Comparison of the choice of clean room wall decoration materials

The clean room, also known as the cleanroom, is now an indispensable and important facility in the semiconductor industry, biochemistry, medicine, and food. With the development of China's economy, more and more applications in industrial electronics factories, pharmaceutical factories, medical operating rooms, intensive care units ICU, burn wards, food processing plants and other places will be applied to clean rooms.

The clean room has the following requirements for the decorative materials in the interior decoration:

1、The building envelope structure and interior decoration of the clean room should be made of materials with good air tightness and small deformation under the influence of temperature and humidity. In-wall decoration When additional structural skeletons and insulation layers are required, non-combustible or difficult-to-burn bodies should be used.

2、The surface of the clean indoor wall and ceiling should meet the requirements of smooth, smooth, no ash, avoid glare, easy to remove dust; reduce the concave and convex surface, fill the corners of the yin and yang. Dry cleaning should be used for interior decoration. For plastering, advanced plastering standards should be used.

3、The floor of the clean room should meet the requirements of leveling, wear-resisting, easy dust removal and cleaning, difficulty in accumulating static electricity, avoiding glare, and having comfort.

4、Reliable sealing measures should be taken for the construction and construction gaps of clean room doors, windows, walls, ceilings and floors (floors).

5、The color of the clean room should be light and elegant.

Different clean rooms also need to consider different individual needs when selecting interior materials:

1. The clean room usually needs to be wiped frequently. In addition to wiping with water, it will be wiped with disinfectant water, alcohol, other solvents, etc. These liquids usually have certain chemical properties, which will cause some materials to discolor and fall off. This requires decoration. The surface of the material has a certain chemical resistance.

2. The biological clean room, such as the operating room, is usually equipped with a trioxide O3 generator for sterilization purposes. O3 (Ozone) is a strong oxidizing gas that accelerates the oxidative corrosion of objects in the environment, especially metals. It also causes the surface of the general coating to fade and discolor due to oxidation. Therefore, such clean rooms require that the decorative materials have good oxidation resistance and no rust.

Color steel plate is a widely used material in the current clean room. With insulation function, production and installation are fast and fast, so many clean workshops with low purification level are widely used.

The weakness of the color steel plate is also obvious, that is, the steel plate is easily oxidized and rusted, especially in a humid environment. Once the surface coating of the color steel plate is collided and detached, the exposed steel plate is oxidized and rusted, which becomes a breeding ground for bacteria. This is very dangerous in a biological clean room.

The chemical-resistant color steel plate jointly developed by Wiskind and DuPont is suitable for the enclosure structure of the new GMP clean room disinfection area. It is used in the environment of VHP disinfection, panel disinfection and new Jieer liquid wiping in biological products and blood products. The ultimate professional performance.

As a dream-grade panel for clean boards, DuPont Tedlar polyvinyl fluoride film is safe and environmentally friendly. The clean surface does not support bacterial growth and meets the US Food and Drug Administration (FDA) standard 21 CFR 175.210, which is in contact with food and is RoHS compliant. The composition is composed of a 100% fluororesin film and a metal-coated steel plate special adhesive, and a DuPont special adhesive is used.

It has at least 50 years of weather resistance, excellent mechanical properties, excellent ductility, and resistance to a wide range of chemicals, solvents and colorants. The dense film surface has no pinholes, cracks and other defects, is resistant to stains, easy to clean, excellent in fire resistance, and safe and environmentally friendly.
