In the past, most engineering companies used a traditional on-site construction technology, which resulted in high labor costs and long construction periods. Now there are cleanroom steel doors that directly reduce and shorten the construction period. It is a door that can be directly used for assembly. The door leaf is directly buckled or welded by steel plates. The door frames are mostly custom steel frames with a surface Electrostatic resin powder spraying has a simpler design and looks more beautiful and atmospheric. As a professional manufacturer of cleanrooms, Wiskind tells everyone why cleanroom steel doors are so popular?

1. Wide use environment

Cleanroom steel doors have high strength, are not easily deformed under normal external forces, are strong and durable, and are not afraid of water erosion. Hospitals and clean workshops are usually crowded. Ordinary color steel doors have a high probability of collision and scratches, so cleanroom steel doors are especially suitable for use in public environments such as electronics and medical treatment.

2. Durable

The cleanroom steel door uses a steel frame inside and is filled with honeycomb. It is lighter than ordinary solid wood doors, is not easy to corrode, and is more durable. It is very convenient to transport and install, and it greatly reduces the drop limit of the door during use. It is not easy to produce the consequence of falling and unable to close due to long-term use.

3. Beautiful style

The cleanroom steel doors come in various styles and colors. Different styles and colors of cleanroom doors can be produced according to the characteristics of customer requirements, so that the entire space is rendered more beautiful and generous. Different colors will bring customers better mood.

4. Quick installation

For dealers, the advantage of the cleanroom steel door is that it is easy to install, and two workers can quickly install it in place. The operation is convenient, simple and fast. The steel door of the ward that does not need to open the lock hole is even less work. The program can be easily installed in place.

5. Economical price

A particularly important point is that the price of cleanroom steel doors is affordable, and it is also affordable by most public construction units. This is also one of the reasons why steel doors are relatively popular. According to the industry, in the next 3-5 years, Sales of clean steel doors will continue to soar.

6. Green and environmental protection

Because the materials used in cleanroom steel doors are all non-toxic materials, installation and use can be green, healthy and environmentally friendly, so this is also one aspect of the door body that relevant departments strongly recommend.

The cleanroom steel door has its own advantages and disadvantages due to its material and manufacturing process. As long as we avoid installing it in a complex outdoor environment during the selection process, pay attention to appropriate protection measures during use. Its advantages are compared with wooden doors, Resin doors are more prominent, so these six characteristics are also an important reason why cleanroom steel doors will become a boom in hospital doors.

Before the design of different clean rooms, you may think too much about the use of space, personnel passages, and even consider cleanroom sandwich wall panels, cleanroom doors, and floors. They will not give too much consideration to the clean room ceiling system, even though it is clean. The room ceiling system is often overlooked, but this is an extremely important part of the clean room.

Why is clean room ceiling important?

Cleanroom ceiling panels need to do more than just close the clean room. The ceiling panel contains many fixtures and accessories, which are essential for the normal operation of the clean room environment. Especially when installing the ceiling panel, people need to walk around, which requires The cleanroom sandwich panel meets the standard in terms of overall strength and flexural bearing capacity. The ceiling panel is extremely important for later equipment maintenance.

Second, the cleanroom ceiling may include holes for HEPA filters (to remove fine particles in the air) and lighting devices that can provide your workers with the high-quality lighting they need to perform their jobs. The seals around the filter and other components must be of sufficiently high quality to prevent the entry of contaminants, such as fine particles that may interfere with the work inside the cleanroom. For all these reasons, choosing the right ceiling for a cleanroom is very important, and making the wrong choice will affect the performance of the clean room.

Why choose walkable ceiling panel?

The walkable ceiling panel is important because it allows maintenance personnel to safely enter the top of the clean room during construction and maintenance. This ensures that your clean room is kept in good condition, and filters and other accessories are replaced as needed to maintain control of the environment. By choosing your walking ceiling, you can make it easy for maintenance personnel to inspect these components regularly, thereby reducing the risk of accidental maintenance problems coming up from and derailing planned projects.

Clean room ceilings must sometimes withstand harsh conditions. It is very important to deal with moisture, smoke, temperature changes and other environmental hazards without losing its structural integrity. To protect your clean room from such situations, choose a walkable ceiling made of non-combustible, stable materials. The best walkable ceilings usually use rock wool cleanroom ceiling panels. Rock wool has high strength and will not absorb moisture in a humid environment and cause damage to the cleanroom panels.

Learn more about walkable ceilings, the more you know about clean room ceilings and other aspects of clean room construction, the more choices you can make for your facility. Identify the options available for clean rooms, including modular clean rooms, clean rooms with walkable ceilings, and soft wall clean rooms.

Cleanroom wall panel uses special color-coated steel plate, stainless steel, etc. as the panel, and is composited with rock wool, glass magnesium board, aluminum honeycomb, etc. as the core material. The product has excellent performance and is an ideal clean room enclosure material. Cleanroom panels are used in the construction of hospitals, pharmaceuticals, food, and electronic workshops.

However, there are many types of cleanroom wall materials, and different cleanliness levels require different cleanroom wall panel systems. It is also very important to choose different clean wall panel core materials in the construction of cleanrooms. Wiskind, as a cleanroom wall panel manufacturer for more than 40 years, Accumulated numerous cleanroom panel options.

Is food safe after the epidemic?

With the normalization of COVID-19 and its profound impact on the economy and society, people’s attention to food safety and nutrition has reached an unprecedented height. The continuous outbreak of food safety incidents in the society, especially the nutritional catering for students, has made countless parents full of worries and made people put forward higher demands on the food industry.

At present, domestic students’ nutritional catering is uneven, industry standards are not uniform, factory design is backward, and modern equipment is few. Looking at various conditions, it is difficult to meet the requirements of student nutritional catering in the new era. The China Safe Food Promotion Office has mentioned the “central kitchen” model many times in public, and believes this is a new way of solving food safety.

What is a central kitchen?

The so-called central kitchen mainly refers to the centralized catering and distribution center. The main task is to carry out pre-treatments such as cleaning, decomposition and proportioning of then food materials and ingredients required by the restaurant through standardized operation and management, and then distribute them to each store, or reheat or combine and sell to customers.

As a professional nutritious fast food catering company, Shizhicai mainly serves students in various campuses, and employees of small and employees of enterprises of all sizes, and provides nutritious, hygienic and delicious food professional services.

The central kitchen it uses includes vegetable cleaning area, meat product processing area, oil area, cooking area, aquatic product processing area, etc. The construction of different areas needs to avoid high oil, high temperature, high humidity, disinfection, organic solvents and other environmental problems. Therefore, the requirements for cleanroom panels are extremely strict, and a little carelessness will cause bulging and blistering problems.

As the first enclosure system service provider to enter the central kitchen field, Wiskind has accumulated numerous application environment solutions. For different use environments, Wiskind has different panel options, such as color-coated cleanroom panel, 304/316L stainless steel cleanroom panel, Endure^® cleanroom Panel, provide unique value for customers in the professional field.

In terms of production process, Wiskind cleanroom panels are produced by the world’s first continuous production line with independent intellectual property rights. Precise spray glue, automatic arrangment of rock wool,  31m ultra-long double crawler is hot-pressed and the precision, strength and flatness of cleanroom panels have been greatly improved. Really do “science and technology to make every cleanroom panel quality is the same”.

As we all know, the central kitchen needs to be washed frequently due to the cleaning and disinfection of processing tools and cooking, and there is a large amount of water accumulation, which not only corrodes the outer steel plate, but also affects and destroys the weighing and structure of the panels. Therefore, when installing cleanroom panels on the ground, it is necessary to do a good job of waterproofing. Aiming at the problem of waterproofing, Wiskind introduced a brand-new stainless steel groove waterproof joint, which completely avoided the problem of corrosion and blistering of the panel surface due to washing, which would affect the service life of the plant.

In the past few years, the central kitchen, a name that is familiar and unfamiliar to consumers, is becoming the key to transforming the catering industry’s supply chain. Central kitchens are rapidly emerging, starting a new revolution in the kitchen industry. In the field of food clean room, Wiskind has accumulated rich industry experience, product concept of integrate solutions, and exerts its own advantages in the construction of standardized central kitchens to fully protect food safety and health.

Food hygiene directly affects people’s health. Whether it is a processing workshop or a packaging workshop in a food factory, there are very high hygiene standards and requirements. Among them, microbial contamination is the most important factor affecting the quality of food, and it is also the focus of clean engineering in food packaging workshops and processing workshops. Therefore, in the field of food production, it must be clean and safe. According to national production standards, food clean rooms need to meet the 100,000-level air purification standard. The construction of clean workshops in food factories can effectively reduce the deterioration of the products produced, extend the shelf life of food, and improve production efficiency. As the largest manufacturer of cleanroom panels in China, Wiskind puts forward the following precautions for the construction of food cleanroom factories.

1. What is a clean room?

Clean room is also called dust-free workshop, clean room, and clean room. It refers to the removal of particles, 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, lighting, and static electricity are controlled within a certain range of requirements, and a specially designed room is given. No matter how the outside air conditions change, the room can maintain the originally set required performance characteristics such as cleanliness, temperature, humidity, and pressure.

What is a class 100,000 clean room?

There are no more than 3.52 million particles with a diameter of ≥0.5μm per cubic meter of air in the workshop. The fewer particles in the air, the less dust and microorganisms, and the cleaner the air. The 100,000-class clean room requires 15-19 air exchanges per hour in the workshop, and the air purification time after complete air exchange does not exceed 40 minutes.

How is the food clean room distributed?

General food clean room can be divided into three areas: non-clean area, quasi-clean area, clean operation area.

Non-clean areas: general storage areas for raw materials, finished products, tools, packaging and finished products transfer areas and other areas with low exposure risk of raw materials and finished products, such as outer packaging room, raw and auxiliary material warehouse, packaging material warehouse, outer packaging workshop, finished product warehouse, etc.

Quasi-clean area: no need for secondary dressing, such as raw material processing, packaging material processing, packaging, buffer room (unpacking room), general production and processing room, non-ready food inner packaging room and other finished product processing but not directly exposed areas.

Clean operation area: Refers to the highest sanitary environment requirements, personnel and environment requirements are high, and must be disinfected and changed before entering, such as: raw materials and finished products exposed processing areas, cold processing rooms for edible foods, cooling rooms for ready-to-eat foods, and waiting for packaging Storage room for instant food, inner packaging room for instant food, etc.

Points to note in clean room construction?

1. The calculation of air exchange rate in the workshop must have sufficient air exchange rate and ensure positive pressure.

2. The temperature and humidity control in the workshop has reached the requirements.

3. The locker room, buffer room, hand washing and disinfection, and other facilities for the staff’s secondary change are designed to meet the requirements of the staff.

4. The design of the air shower room.

5. The installation of environmental disinfection facilities in the workshop, such as ultraviolet lamps.

6. The installation of anti-rodent and fly-proof facilities in the workshop, such as fly-killing lights.

7. The location of the air inlet of the workshop should be set up at the air inlet, and there should be a filter system, and should be closed when the machine is shut down.

8. The design of the return air outlet or the return air wall ensures easy cleaning.

9. Treatment of the workshop floor and sewers without stagnant water, and ensure that the sewers are deodorized.

10. The design of the safety door in the workshop to ensure the safety of employees.

In late-stage clinical trials in Brazil, Sinovac Biotech’s vaccine has shown 78% effectiveness in fighting COVID-19, and 100% can prevent severe illness.

China Sinovac Biotech cooperated with Butanta Research Institute, Brazil’s largest vaccine manufacturer, to conduct Phase III clinical research in Brazil. The agency said on Thursday that among the volunteers vaccinated, there were no severe cases. Although the effectiveness of Sinovac Biotech CoronaVac vaccine is not more than 90% like Moderna, this vaccine is easier to transport and can be stored at normal refrigerator temperature.

In December 2020, Sinovac Biotech announced that it is expected to produce 300 million doses of vaccine in 2020 and increase its production capacity to 600 million doses per year. Sinovac Biotech built a factory in Beijing for the production of the COVID-19 vaccine. At present, Sinovac Biotech’s vaccine research and development laboratory in China is provided by Wiskind with cleanroom materials, using a total of 15,000 square meters of cleanroom panels.

In view of the particularity of the vaccine laboratory, and taking into account the strength and aesthetic performance of the required cleanroom panels, Wiskind provides magnesium rock wool cleanroom panels, which have the advantages of drug resistance, corrosion resistance, and pollution resistance. It is a pharmaceutical experiment Ideal for the room.

As a professional cleanroom enclosure system service provider, Wiskind has the world’s first cleanroom panels production line with independent knowledge products, which can produce a variety of core materials and can be customized to meet the needs of different industries. It has been used in pharmaceuticals, food, electronics, and hospitals. Provide professional cleanroom panels and technical support services for hundreds of customers in many fields.

Moscow-based “R-Pharm” will become a leading manufacturer of Russia’s Sputnik V covid-19 vaccine.

On December 11, 2020, Moscow Mayor Sergei Sobyanin and R-Pharm Chairman Alexey Repik checked the progress of the production of the vaccine against Covid-19 in the Moscow plant. The project is being developed by R-Pharm. Wiskind provided more than 40,000 square meters of rock wool cleanroom panels, cleanroom doors and other cleanroom enclosure products for the project.

The production base will produce the flagship home vaccine “Sputnik V” developed by the Epidemiology and Microbiology Center. According to this project, when the factory reaches full capacity, it will produce up to 20 million doses of vaccine every month. The total investment in the project amounts to 8.6 billion rubles. The R-Pharm enterprise plans to start at the end of December 2020, and the first batch of Sputnik V vaccines are planned to be produced in Moscow Technopolis in January 2021. The construction of the complex located on the territory of the special economic zone “Technopolis “Moscow” took place in record time, which is necessary for the implementation of national and urban vaccination programs. The area of the new factory will exceed 20,000 square meters.

At present, high-quality steel cleanroom doors are widely used in engineering fields such as biopharmaceutical, food, electronics and medical industries. In China, there are many steel cleanroom door manufacturers with uneven products and low market positioning. Each manufacturer mainly focuses on quantity, but ignores the quality of the product.

So how can we buy high-quality steel cleanroom doors? After more than 40 years of development of Wiskind , during the production process, several points need to be paid attention to:

Thickness of door leaf steel plate

When buying cleanroom doors, you need to know the thickness of the door leaf. The thickness of the door leaf of the steel cleanroom door of the general manufacturer is 0.4-0.6mm, while the thickness of the steel cleanroom door leaf of Wiskind is 0.6-0.8mm, although we cannot see the real The thickness of the plate of the steel cleanroom door, but the thickness of the steel plate must be particularly emphasized when purchasing, and sampling can be done.

Door surface spraying

Many ordinary spray paints use relatively cheap raw materials, but steel cleanroom doors must use high-quality environmentally friendly raw materials, because they are indoors, they must use high-quality raw materials. The quality of the inspection door surface mainly depends on the hardness, flexibility, flatness, color, etc. of the paint film. The hardness should be scratched without scratches, and the flexibility should be bent to a certain degree without cracks. The flatness can be touched by hand, no blemish, full color, hand feeling, no particles on the paint surface, but it is not as smooth as possible. The surface of the steel cleanroom door of Wiskind is sprayed with electrostatic resin powder.

Window on the door

There are single-layer and double-layer windows on the door, but currently the windows on the door are mainly double-layer glass. The quality of the windows determines the use time. The poor quality windows are prone to fogging after long-term use, which affects the appearance , And Wiskind cleanroom window adopts patented window keel. The ventilation holes are arranged uniformly and long on both sides of the keel. The 3A molecular sieve reacts with the air in the cleanroom window through the gaps on both sides to ensure the anti-fogging performance of the cleanroom window.

Door Hardware

The quality of the door hardware will directly affect the use of the door. Wiskind cleanroom door locks use customized German locks, which have passed 500,000 opening and closing experiments, two-year warranty for the entire door, and free lifetime maintenance services. At the same time, the Wiskind cleanroom door is the first product in the industry to be tested by the National Construction Engineering Quality Supervision and Inspection Center. It can achieve multiple indicators such as wind pressure/air tightness/soft impact resistance, vertical load resistance, and static distortion resistance.

Wiskind cleanroom door and window product series are divided into steel cleanroom doors, stainless steel doors, aluminum cleanroom doors, hollow cleanroom windows, fire-resistant windows, and dimming windows. According to different industries and use environments, we can provide cleanroom enclosure system solutions and related technical service support.

China built the world’s largest new crown vaccine production plants, mass production annual capacity of 100 million, have to meet the large-scale use of emergency and routine vaccination production conditions. The new crown vaccine production workshop project has professional systems, tight schedules control and so on, these are the difficulties of the project. In order to successfully complete the construction, the project team organized several special rush meetings to orderly schedule the procedures during the construction process, which is particularly critical in terms of material procurement and construction plans.

At Wiskind, we can quickly provide all the materials needed to build a clean room and provide one-stop service. At the same time, for some projects with tight time and heavy tasks, we can provide modular clean rooms, fast assembly, and standardized production. Increase the efficiency of clean room material production and construction more than 15%, shorten the construction period by 20% to 40% , and greatly improve the quality of construction. This means that your team can start using new facilities as soon as possible, thereby greatly reduces work delays , and further promote the industry’s profitability model changes.

Modular clean room includes cleanroom doors, cleanroom windows, and cleanroom panels. The high flexibility of modular clean room design means that you can choose to use other clean room equipments to maintain stricter environment control. At the same time, the modular clean room has great advantages over the brick and mortar clean room structure. You can solve the damage of the clean room wall by replacing a single clean wall panel without having to consider replacing  entire structure. Wiskind invented a removable sandwich wall panel, through the development of removable accessories to connect the panel, which can removed part of the wall.

As a global supplier, we tend to have different opinions and suggestions from customers, and take this opportunity to learn more about the benefits of modular clean rooms to find out whether they are suitable for your organization. These suggestions can increase our overall design and construction of modular clean rooms, help us make better changes.

What is a pass box?

The pass box is an auxiliary device of the clean room, which is mainly used for the transfer of small items between the clean area and the clean area, the non-clean area and the clean area, so as to reduce the number of door openings in the clean room and minimize the clean area. Pollution. The pass box is made of stainless steel plate, smooth and clean, the two doors are interlocked with each other, effectively preventing cross-contamination, equipped with electronic or mechanical interlocking devices, and equipped with ultraviolet sterilization lamps. Transfer windows are widely used in micro-technology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCDs, electronics factories, etc. wherever air purification is required.

The pass box is divided into three categories: 1. Electronic interlocking pass box 2. Mechanical interlock pass box 3. Self-cleaning pass box

Pass box can be divided into air shower type pass box, ordinary pass box and laminar flow pass box according to the working principle. Various models of pass box can be made according to actual requirements.

Optional accessories: walkie-talkie, germicidal lamp and other related functional accessories.

Working Principle:

⒈Mechanical interlock device: The internal interlocking is implemented in a mechanical form. When one door is opened, the other door cannot be opened. The other door must be closed before the other door can be opened.

⒉Electronic interlocking device: internally integrated circuits, electromagnetic locks, control panels, indicator lights, etc. are used to achieve interlocking. When one of the doors is opened, the indicator light of the other door is off, telling that the door cannot be opened, and the electromagnetic The locking action realizes interlocking. When the door is closed, the electromagnetic lock of the other door starts to work, and the indicator light will illuminate, indicating that the other door can be opened.

Instructions:

The pass box is managed according to the cleanliness level of the higher-level clean area connected to it. For example, the transfer window connecting the coding room and the filling room should be managed according to the requirements of the filling room. After get off work, the clean area operator is responsible for wiping the internal surfaces of the pass box and turning on the ultraviolet sterilization lamp for 30 minutes.

1. Materials entering and exiting the clean area must be strictly separated from the flow channel, and entering and exiting through the dedicated material channel in the production workshop.

2. When the material enters, the raw materials and auxiliary materials will be unpacked or cleaned by the person in charge of the preparation process, and then sent to the temporary storage room of the raw materials through the delivery window; after the inner packaging materials are removed from the outer temporary storage room, Sent into the private room through the pass box. The workshop comprehensive staff handles the material handover with the person in charge of the preparation and inner packaging process.

3. When passing through the pass box, the regulations of “one opening and one closing” of the inner and outer doors of the pass window must be strictly implemented, and the two doors cannot be opened at the same time. Open the outer door to put the material in, then close the door first, then open the inner door to take out the material, close the door, and so on.

4. When the materials in the clean area are sent out, the materials should be transported to the relevant material intermediate station first, and moved out of the clean area according to the reverse procedure when the materials enter.

5. All semi-finished products are transported out of the clean area from the pass box to the temporary storage room, and then transferred to the outer packaging room through the logistics channel.

6. Materials and wastes that are highly susceptible to pollution should be transported from their dedicated delivery windows to unclean areas.

7. After the materials are in and out, the cleanliness of the clean room or the intermediate station and the pass box should be cleaned in time.

Precautions:

1. The pass box is suitable for general transportation. During transportation, it is protected from rain and snow to avoid damage and rust.

2. The pass box should be stored in a warehouse with a temperature of -10℃~+40℃, a relative humidity of not more than 80%, and no corrosive gases such as acids and bases.

3. When unpacking, work in a civilized manner, without rough or brutal operations, so as not to cause personal injury.

4. After unpacking, please first confirm whether this product is the intended product, and then carefully check the contents of the packing list for missing parts and whether any parts are damaged due to transportation.
