Cleanroom panel also called modular cleanroom panel, Cleanroom panels are widely used for multiple purposes including pharmaceutical cleanroom, electronic cleanroom, food cleanroom, office partition as well as hospital operating room, etc.
In the clean room panel installation process, will involve two categories of problems, the first is the cleanroom wall board opening problem, including clean switch socket, safety exit indicator light and other small holes, the second type of problem is the clean board electrical system installation, including clean lights.
At present, there are many ways to cleanroom the wall panel, the main reason is that the site opening flexibility is relatively large, the construction efficiency is high.
In terms of cleanroom wall panels opening, article 4.3.4 of clean room construction and acceptance code stipulates that metal sandwich board is not easy to open holes on site.All kinds of holes on the panel should be cut square, neat edge, the edge of the filling material should be used to evenly inlaid sealant seal;
The biggest problem for the small hole is the presence of dust inside the hole, which enters the indoor hidden danger through the gaps such as switches and sockets. At the same time, the dust enters the interior of the electrical appliances, which will also have a certain impact on the life or safety.
For large holes such as air supply outlets, lamps, columns, etc., if no special treatment, there will be secondary pollution, and the overall strength of the plate will decline, especially in the clean plate installation project.
Therefore, to reduce the hidden danger as much as possible, the location of the hole must be pre-processed, preferably in the factory pre-fabricated processing.This includes the installation of electrical systems and the preinstallation of wire pipes.

According to the requirements of the laboratory, the biological lab cleanroom was designed with a construction area of 23㎡ as an example. There should be a P2 main laboratory (P2 laboratory is Physical Containment Level 2 Laboratory), a one-buffer room, a two-buffer room, and a scrubbing and disinfecting room.
Plan the layout according to the relevant national regulations and the special requirements of the experimental site. Consider that the biosafety laboratory should implement the requirements of the first-level barrier and the second-level barrier at the same time. The first-level barrier is mainly reflected in the layout and maintenance structure of the microbiological experiment area. The secondary barrier is mainly reflected in the air-conditioning purification system.
1. Separate the flow of people and logistics in the plane layout to prevent cross infection of people and things.
2. The experiment operator enters the P2 main laboratory through the first buffer room and the second buffer room, and the experimental objects enter and exit the P2 main laboratory through two interlocking pass boxes.
One of the interlocking pass boxes is located between the main laboratory and the preparation room, and the other is located between the main laboratory and the scrubbing and disinfecting room, which ensures that the cleans are not infected, and at the same time ensures that the pollutants are passed into the scrubbing and disinfecting as soon as possible The room is sterilized.
2. Enclosure Cleanroom Materials
The design requires that the cleanroom wall of the laboratory is a cleanroom panel with a thickness of 50mm, and the core material is non-combustible. Wiskind is a supplier of modular cleanroom enclosure materials. Rockwool cleanroom panel is recommended. It features high flatness, corrosion resistance, thermal insulation and fire protection. Can meet the requirements of the overall biological lab cleanroom.
The ceiling material is also a cleanroom panel. The indoor ground of the microbial area is welded with imported PVC materials without gaps, which has the characteristics of corrosion resistance, strong wear resistance, good flatness and easy cleaning.
The ground corner line is decorated with negative angle clean room aluminum material, which is beautiful and tight. Through scientific design and careful construction, the overall laboratory will form a sterile, seamless, smooth, beautiful, non-reflective, dust-free, rust-free, moisture-proof, anti-bacterial, and high-performance sterile surface and inner shell in the laboratory. Thereby solving the problems of air tightness and cleaning.
All materials of Wiskind modular cleanroom are processed and formed in the factory according to the design drawings, and shipped to the site for rapid installation. All the equipment in the room is embedded in the wall, making the wall of the whole laboratory smooth and seamless, preventing dust accumulation, and convenient for cleaning and disinfection.
3. Basic Configuration of Microbiology Laboratory
In addition to solving the problem of air purification, the clean laboratory should provide as much convenience as possible for the experimental work, so some necessary laboratory equipment should be considered in the design.
1. Interlocking pass box: equipped with two transfer windows in the P2 laboratory. Ensure the safety of laboratory logistics. There is an ultraviolet lamp in the interlocking transfer window, which is disinfected before the contaminated items are taken out of the laboratory. The interlocking transfer window also ensures the isolation of outdoor and indoor air, which facilitates the transfer of items by experimenters and reduces the entry and exit of experimenters The frequency of the laboratory. Both the indoor and outdoor transmission windows can be controlled.
2. Automatic door closer: According to the requirements of national regulations, an automatic door closer is installed on the clean laboratory door.
3.Interlocking cleanroom door: The main laboratory is equipped with a set of two interlocking electronic interlocks. When one of the doors is not closed, the other door will not open. This will buffer the airflow into the clean room. The interlocking door is also equipped with an emergency switch. When an accident occurs, press the emergency switch to facilitate laboratory personnel to escape from the scene as soon as possible.
4. Socket: According to laboratory use requirements. In each laboratory, according to different experimental purposes, a sufficient number of single-phase sockets and three-phase sockets should be configured. The sockets are all embedded and air-tight. The imported multi-functional dust-proof, waterproof and anti-leakage combined power supply board is imported, and it is installed with advanced technology.
5. Ultraviolet lamps: Considering the disinfection requirements of the clean room, two ultraviolet disinfection lamps should be equipped in the P2 main laboratory to facilitate the physical disinfection before and after the experiment.
Sample cart: In order to facilitate laboratory personnel to move samples and other experimental supplies, a small sample cart should be specially arranged in the scrubbing and disinfecting room. It is a stainless steel structure with two layers on the top and bottom, which is small and convenient to promote.
7. Biosafety cabinet (BSC-Ⅱ-A2): According to the requirements of the national regulations of the biosafety laboratory, the P2 laboratory should be equipped with a biosafety cabinet. Biological safety cabinets are the main isolation equipment used in biological laboratories to prevent the spread of harmful suspended particles. Based on the protection provided to people, the environment and the samples of the test article, the level varies. Class II A2 biological safety cabinet can provide comprehensive protection for personnel, test samples, and environment, and is applied to the operation of high-risk microorganisms, toxic substances and radioactive oligonucleotides. A2 type A2 is a front-door biological safety cabinet, which protects the staff by vertical airflow, protects the samples by multi-layer HEPA filtration, and protects the environment by HEPA filtration exhaust gas. The airflow settles from the top of the cabinet through the HEPA intake filter. After the gas reaches the working surface, about 50% of the gas is sucked into the rear grille of the cabinet, and the remaining gas meets the indoor air at the front grille, of which 30% of the air can pass through The HEPA exhaust filter is discharged, and the remaining 70% of the air is mixed with fresh air through HEPA filter to form a sterile work area, which effectively prevents cross-contamination. A gas barrier is generated where the indoor air meets the HEPA filtered air, so that the staff and the sample are isolated, protecting the safety of the experimenter, and the sample is not contaminated.
The biological clean room should strictly follow the health industry standard of the People’s Republic of China WS233-2002 “General Guidelines for Biosafety in Microbiology and Biomedical Laboratories” and the National Standard GB19489-2004 “General Requirements for Laboratory Biosecurity” The assembly standard is to assemble different levels of biological clean rooms for users according to the degree of biological hazards of the biological factor analysis process carried out by various professional laboratories and according to the biological safety level classification in national standards. Called level 1, level 2, level 3, and level 4.
P1 treatment objects are less harmful to humans, animals or the environment, and do not have pathogenic factors that cause disease to healthy adults, animals and plants. P2 is a moderately hazardous or potentially dangerous pathogenic factor for humans, animals, plants or the environment, and will not cause serious harm to healthy adults, animals and the environment. Effective prevention and treatment measures.
P3 is highly dangerous to humans, animals and plants or the environment, mainly through aerosols to cause serious or even fatal diseases, or pathogenic factors that are highly harmful to animals, plants and the environment. There are usually preventive treatments.
P4 is highly dangerous to humans, animals, plants or the environment. It is transmitted by aerosol or its transmission route is unknown, or unknown and dangerous pathogenic factors. There is no preventive treatment.
2. Main technical indicators of clean laboratory

3. Expression of cleanliness
Cleanliness class 10000 (P20,000 laboratory is ISO7 level), that is, the number of dust particles greater than or equal to 0.5μm is greater than 35000 particles / m3 (35 particles / L) to less than or equal to 350,000 particles / m3 (350 particles / L) The number of dust particles greater than or equal to 5 μm is greater than 300 particles / m3 (0.3 particles / L) to less than or equal to 3000 particles / m3 (3 particles / L).
5. Purified Air Conditioning System
The microbial clean room is equipped with a purification air-conditioning system in order to establish a micro-environment with suitable temperature, humidity, fresh air, and aseptic cleanliness to facilitate the experimental operation. The traditional air-conditioning system can only control the temperature to a certain degree, and the cleanliness cannot be completely controlled, thus causing the breeding and reproduction of bacteria. Such an air conditioning system is far from meeting the hygienic requirements of a specific clean environment in a microbiology laboratory.
After being carefully designed through a series of technical measures, the purification air-conditioning system can fully control the temperature, dust, bacteria, harmful gas concentration and airflow distribution in the laboratory, ensure the fresh air volume required by indoor personnel and reasonable indoor airflow direction Maintain the appropriate gradient pressure and directional flow throughout the microbiology laboratory, fully realize the purpose of “sterile environmental protection system”, and reduce all potential infection risks during the experiment. Another outstanding feature of the structural design is that most of the indoor air conditioning equipment maintenance is performed outdoors, reducing the chance of non-experimental personnel entering the laboratory, reducing pollution, and improving the utilization rate of the laboratory.
6. Power Distribution System
The design scope of the engineering power distribution system is the lighting and power system of the laboratory and the power supply and distribution system of the air-conditioning unit of the microbiology laboratory. The design is based on “Code for Design of Power Supply and Distribution System”, “Code for Design of Low-Voltage Power Distribution”, “Standard for Lighting Design of Civil Buildings”, “Code for Electrical Design of Civil Buildings”, “Technical Specification for Building of Biosafety Laboratory”, “Biosafety for Laboratory “General Requirements”, “General Guidelines for Biosafety of Microbiology and Biomedical Laboratories” and the tender documents provided by the experimental site are the design basis.
Laboratory power distribution: It is designed to set up a power distribution sub-box for the biological safety laboratory, and the main circuit of the power distribution will lead to a separate circuit for power distribution, so as to ensure the reliability and safety of laboratory electricity. In addition, the power distribution of other auxiliary laboratories is carried out in a mode laid separately from the microbiological safety laboratory, thereby further ensuring the reliability of electricity use in the biosafety laboratory; the lighting distribution of the main laboratory is separated from the socket power distribution.
From the spring of 2003 to the Spring Festival of 2019, China experienced two undefeated wars. If the medical personnel are fighters in these two wars, Modular container houses have built trenches to ensure victory in the two wars.
In these two wars, the most famous are the Beijing Xiaotangshan Hospital in 2003 and the Wuhan Vulcan Mountain Hospital in 2019. The two hospitals are both emergency infectious disease hospitals, and they were built in a very short period of time, but the construction of the two hospitals also demonstrates the transformation and development of Wiskind’s prefabricated building technology.
Modular container house is a movable and reusable building product. Its unit module is mainly composed of box top, box bottom, upright, wall, door and window accessories. It adopts modular design and factory production, and uses the box as the basic unit. It can be used alone, or it can form a spacious use space through different combinations of horizontal and vertical directions. The vertical direction can be laminated.
Modular container houses are generally used for temporary houses, field work houses or emergency houses. For example, real estate development company sales exhibition halls, product sales exhibition halls, temporary reception centers, commercial temporary offices, shops, etc., resort hotels, restaurants, exhibition halls, art centers, etc. in tourist cities, office, accommodation, conferences of construction site project managers Office, field exploration and construction mobile office, dormitory, etc., military mobile command center, emergency mobile command center, disaster relief mobile command center, etc. The main structural forms of Wuhan Huoshenshan Hospital and Raytheon Mountain Hospital, the hospitals that are currently in use to specially treat patients to fight against the new crown epidemic, are on-site assembly of box-type rooms with container movable panels.
What are the advantages of Modular container houses?
Steel structure modular container houses have five outstanding advantages, which are very suitable as emergency rooms for hospitals or temporary products:
1. It is convenient to transport, prefabricated and produced each component directly in the factory, and it can be directly assembled on site, convenient for disassembly and assembly.
The building components are standardized in design, and the products are in plate packaging, which is convenient for transportation and saves space. The box unit structure is a standard member welded with special steel, and the boxes are connected by bolts, and the structure is simple. Because the accuracy of the components is ensured, on-site installation can be fast and precise. The house can be recycled and can be disassembled and reassembled at will, saving energy and protecting the environment. The box house sent to Wuhan in this epidemic is divided into separate parts for easy transportation. It is assembled at the Wuhan construction site according to the drawings, and 4 workers can build a box house unit in 2 hours.
2. Sturdy and durable, strong resistance to earthquake and deformation
The steel as the structure has good ductility, strong plastic deformation ability, and is a green environmental protection material. It has high strength, low self-weight, and good seismic performance. The service life can reach more than 20 years.
3. With heat insulation, moisture proof, waterproof and other properties, and good sealing performance, strict manufacturing process makes it well used in infectious disease hospitals and other fields
Box-type houses transported in short distances can be transported as a whole. Doors, windows, wiring, ceilings, etc. have been shipped from the factory. Air conditioning, electricity, lighting, tables and chairs can be built in. The interior of the house meets the complete decoration standards. , Available immediately.
4. The movable room is based on the standard steel chassis, and the layout is flexible, which can derive many combined spaces.
The modular house has flexible space division. In addition to the horizontal and vertical connection, it can also be placed on top of each other, and a roof platform can be set. The internal space after connection can also be flexibly equipped with indoor partitions and partition walls.
It is precisely with the above characteristics, in this battle of the new crown epidemic, the steel structure box house has become the first choice for the construction of most emergency infectious disease hospitals in China.
In addition, the box house can be industrialized, easy to control costs, and effectively improve building quality, construction is not affected by the season, and there is little construction waste on the construction site, which meets China’s development requirements for green buildings. It has also become one of the reasons for its increasing attention.
COVID-19 has swept through, bringing serious life and economic pressures to people, affecting batches of batches of pharmaceutical companies to continuously develop new vaccines. At the same time, a large number of hospitals and isolation rooms were built, but the With the continuous development, the decorative materials used in the cleanroom have also been replaced with dust-proof and cleanroom panels from the original reinforced concrete, but how to choose cleanroom materials has also become particularly important.
Wiskind conforms to the development of the times, according to the current specifications of cleanroom workshop design, economic and reasonable, safe application, ensure quality, meet the requirements of energy conservation and environmental protection, provide a variety of cleanroom enclosure materials and related cleanroom equipment, not only meet GMP requirements, obtain CE Certification, while the modular structure also improves installation efficiency and safety.
The importance of cleanroom architectural decoration is mainly manifested in the following aspects:
1. The cleanroom requires that the material does not produce dust, the structure does not accumulate dust, and the seal is tight and impervious to dust, so the decorative materials of the cleanroom will directly affect the cleanroom level. The cleanroom material meets the requirements of heat preservation, heat insulation, fire prevention and moisture resistance; the surface is smooth and smooth, without cracks, tight interface, no falling off of particles, resistant to cleaning and disinfection.
2. When the paint layer is used for the cleanroom wall panels and cleanroom ceiling panel, the materials that are corrosion-resistant, clean-resistant, smooth and mildew-resistant are used.
3. Reliable sealing measures shall be taken for the structure and construction gaps of cleanroom doors, windows, walls, ceilings, and floor (floor) surfaces.
Different cleanrooms also need to consider different personal needs when choosing interior decoration materials:
1. Cleanroom usually need to be wiped frequently. In addition to wiping with water, wipe with disinfectant, alcohol, other solvents, etc. These liquids usually have a certain chemical nature, which will cause some materials to discolor and fall off. The surface of the cleanroom panel has certain chemical resistance.
2. Biological cleanrooms such as operating rooms are usually equipped with trioxygen O3 generators for the purpose of sterilization. O3 (i.e. ozone) is a strong oxidizing gas, which will accelerate the oxidative corrosion of objects, especially metals in the environment, and will also cause the general coating surface to fade and change color due to oxidation. Therefore, such a cleanroom requires that its decorative materials have good oxidation resistance and will not produce rust.
Endure® is mainly suitable for clean room enclosures under the environment of VHP (Vaporize Hydrogen Peroxide) disinfection, panel disinfection, and new Jieer (Benzalkonium Bromide) cleaning environment in clean room B areas such as biological products and blood products.Its unique properties include Excellent weatherability, excellent mechanical properties, ductility, and resistance to a wide range of chemicals, solvents and colorants.
Medical masks are made of three layers of non-woven fabrics. The main production processes include meltblown, spunbond, hot air or needle punching. They are equivalent to resisting liquids, filtering particulates and bacteria. They are a kind of medical protective textiles.
Wiskindcleanroom product has been approved by the “National Medical Device Manufacturing License” and “Medical Device Registration Certificate”, and has obtained the qualification for the production and operation of disposable medical masks, which meets the CE certification requirements.
Medical masks are used to block the spouts exhaled from the mouth and nasal cavity, and can be used for one-time hygiene care in general medical environments. It is suitable for general hygiene care activities, such as sanitation cleaning, liquid distribution, cleaning bed units, etc., or the blocking or protection of particles other than pathogenic microorganisms such as pollen.
Medical masks are generally made of 3 layers of non-woven fabrics, of which the outer layer is spun-bonded non-woven fabric, which is waterproofed to block body fluids, blood and other liquids; The woven fabric is the core filter layer; the inner layer is also mainly made of non-woven fabric, which generally has good moisture absorption function.
Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good fold resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt-blown cloth has good filtration, shielding, heat insulation, and oil absorption.
Meltblown cloth can be used in the fields of air, liquid filtration materials, insulation materials, absorption materials, mask materials, warmth materials, oil-absorbing materials and wipers.
Instructions:
1. Carefully cover the mouth and nose with a mask and fasten it to minimize the gap between the face and the mask;
2. Avoid touching the mask when using it-after touching the used mask, for example to remove or clean the mask, wash your hands with soap and water or use alcohol hand sanitizer;
3. After the mask is wet or contaminated with moisture, replace with a new clean and dry mask;
4. Do not reuse disposable masks. Disposable masks should be discarded after each use.
With the rapid development of industrial technology, especially the production of high-tech products such as microelectronics and biomedical engineering, there are increasingly higher requirements, which not only requires the improvement of production technology of process equipment, but also the requirements for the production environment. Harsh. The cleanliness level and production environment of the clean room have a huge impact on the production efficiency and quality of the product. The comfort of the production environment is also related to the comfort and work efficiency of the staff.
The clean room environment has a huge impact on product production. The biggest impact is that the production environment affects the production process and production quality of high-tech products. The air cleanliness of the purification engineering workshop is one of the key factors for the smooth development of high-tech products. Especially in the chip production process of high-tech industries such as microelectronics, the control of particles in the air must reach the molecular level, that is, the non-100-level clean room environment, and it is impossible to produce at all, or even if it can be produced, the quality is difficult. Meet the requirements.
In the production of pharmaceutical products such as biopharmaceuticals, it is necessary not only to control the dust particles in the clean room, to achieve the required production environment and purification level, but also to properly control the bacteria and microorganisms in the air, otherwise the production of the drug is difficult to carry out normally. Even if it is produced, it is mostly defective, and it is difficult to meet the quality standards.
It can be seen that the impact of clean technology on industrial production is enormous. With the continuous development of industrial technology, more and more new products need to be carried out in the clean room. The ordinary production workshop can not meet the production requirements at all, and the conventional The production workshop can not control the whole air environment through the purification equipment. Only the color steel cleanroom panel and the reasonable air volume and pressure difference can meet the requirements of the production.

Wiskind hopes that you can control the microbial particles in the cleanroom, control the product quality, and provide services to your business and customers.
What is a cleanroom?
Cleanroom refers to the removal of particulates, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise vibration and lighting, static electricity are controlled in a certain Within the scope of demand, and given by specially designed rooms. No matter how the external air conditions change, the indoor can maintain the required cleanliness, temperature, humidity and pressure.
What is a 100,000-level cleanroom?
The number of particles ≥0.5μm in the air per cubic meter of the workshop is not more than 3.52 million. The fewer the particles in the air, the less the number of dust and microorganisms, and the cleaner the air. The 100,000-level clean workshop also requires that the workshop must be ventilated 15-19 times per hour, and the air purification time after complete ventilation is not more than 40 minutes.
Food Cleanroom Division
The food workshop can be roughly divided into three areas: general operation area, quasi-cleaning area, and cleaning operation area.
1.General operation area (non-clean area): general raw material, finished product, tool storage area, packaging finished product transfer area and other areas with low risk of raw material and finished product exposure, such as outer packaging room, raw material warehouse, packaging material warehouse, outer packaging Workshop, finished product warehouse, etc.
2.Quasi-clean area: requirements are followed, such as raw material processing, packaging material processing, packaging, buffer room (unpacking room), general production and processing room, inner packaging room of non-ready-to-eat food, etc., but not directly exposed.
3.Clean operation area: This area is often constructed as a clean workshop, usually referring to the highest sanitary environment requirements, high personnel and environmental requirements, such as: raw material, finished product processing area, food cold processing room, ready-to-eat food cooling room, waiting Storage room for packaging ready-to-eat food, inner packaging room for ready-to-eat food, etc.
Cleanroom Design Requirements
1. Food factories with clean workshops should avoid the occurrence of pollution sources, cross-contamination, mixing and errors to the greatest extent during site selection, design, layout, construction and transformation.
2. The factory area is clean and tidy, the flow of people and logistics are reasonable.
3. There should be appropriate access control measures to prevent the entry of unauthorized persons.
4. Preserve construction and construction completion information
5. Buildings with serious air pollution during the production process should be built on the downwind side of the factory area with the most wind direction all year round.
6. When the production processes that affect each other should not be located in the same building, effective separation measures should be provided between the respective production areas. Production of fermented products should have a dedicated fermentation workshop.
Cleanroom Construction Requirements
1. Processes that have sterility requirements but are not able to carry out final sterilization and although they can achieve final sterilization, the process of aseptic operation after sterilization should be carried out in a clean workshop.
2. A clean workshop with good hygienic production environment requirements should include perishable foods, ready-to-eat semi-finished products or finished products, storage and treatment places before final cooling or packaging, raw material pretreatment, product sealing and molding places that cannot be sterilized , The exposed environment after the final sterilization of the product, the inner packaging material preparation area and inner packaging room, as well as the processing and processing places and inspection rooms for food production, improving food characteristics or preservation.
3. The production process of the workshop and the corresponding clean room level requirements are reasonably arranged. The production line layout should not cause round trips and discontinuities.
4. The different workshops connected to each other in the production area should meet the needs of varieties and processes. If necessary, there should be buffer rooms and other measures to prevent cross-contamination. The area of the buffer room should not be less than 3 square meters.
5. Raw material pre-processing and finished product production do not use the same clean area.
6. In the production workshop, areas and spaces suitable for the scale of production are designated as temporary storage areas for materials, intermediate products, products to be inspected, and finished products, and crossover, confusion, and pollution should be strictly prevented.
7. The inspection room should be set up independently, and proper measures should be taken for its exhaust and drainage. If there is a requirement for air cleanliness in the product inspection process, a clean bench shall be provided.
Endure® is mainly suitable for clean room enclosures under the environment of VHP (Vaporize Hydrogen Peroxide) disinfection, panel disinfection, and new Jieer (Benzalkonium Bromide) cleaning environment in clean room B areas such as biological products and blood products.
After several experiments, the Wiskind gave you a comprehensive explanation of VHP disinfection, only for better construction of classrooms. Choose Endure®, all problems will be solved.
After several experiments, the Wiskind team gave you a comprehensive explanation of VHP disinfection, only for better construction of classrooms.
What is VHP? VHP is what we usually call vaporized hydrogen peroxide. It is a technology that utilizes the advantages of hydrogen peroxide at room temperature to kill bacteria and spores and achieves complete sterilization.
As we all know, the biological workshop is a cleanroom with high cleanliness requirements. There are strict control standards for dust particles and microbial levels. The maximum allowable number of suspended particles in cleanroom B areas, such as biological products and blood products, is 0.5µm (micrometer), and planktonic bacteria is 1cfu / m³ (1 colony per cubic meter).
In order to meet these requirements, the biological environment system must be regularly disinfected to control airborne microbial (bacterial and microbial) pollution, and the most commonly used is VHP disinfection. Although VHP is highly effective in sterilization and has no residue, a high concentration of H2O2 will cause corrosion on the color Steel Sheet. H2O2 itself is a strong oxidant, and the surface of the corroded color Steel Sheet will blister.
The reason is that H2O2 penetrates into the middle of the paint coating, decomposes into water and oxygen, and is caused by arching the paint coating under the change of temperature. The use of a thin paint coating with poor denseness and micro-porosity can cause blistering. The blistering is not the corrosion of the steel sheet itself, but the color steel sheet that has lost the protection of the paint coating has a reduced appearance and a greatly reduced service life. What’s more serious is that foaming will also lower the level of the entire cleanroom and affect the quality of pharmaceuticals in the production process.
Think about it, this is really a headache.
How to solve this problem? Group after group of scientific researchers worked hard for research, and Endure® Steel Sheet was born.
Compared with the traditional color Steel Sheet, the Endure® steel sheet has a layer of special high-durability PVC on the surface, which is like adding a layer of shield to effectively block the penetration of H2O2 and fundamentally solve the phenomenon of H2O2 corrosive paint blisters.
Through experimental comparison, the Endure® steel sheet not only has excellent resistance to H202 corrosion resistance but also performs well in specific environments such as acid and alkali.
Therefore, in a VHP disinfection environment, choosing the cleanroom panel made of Endure® steel sheet will prevent your cleanroom from the risks and troubles of blistering of color Steel Sheets.
