Cleanroom wall panels are designed to meet the process requirements of cleanrooms. It is generally composed of three parts: surface material, core material and connecting material. The wall surface must meet the requirements of being smooth, dust-free and easy to clean, and the material must be wear-resistant and anti-static. The surface material refers to the surface decoration material seen from the inside of the cleanroom and isolated from the external environment. Commonly used ones include sandwich panel, aluminum alloy panel, stainless steel panel, etc. The core material refers to the infill between the surface materials. Commonly used ones include rock wool, polyurethane, glass magnesium, etc. The connection materials mainly include aluminum alloy profiles, screws, expansion tubes, expansion screws, bolts, etc.

The properties that cleanroom wall panels generally need to have include anti-static, corrosion resistance, environmental protection, easy cleaning, sound insulation, etc.:‌

(1) Antistatic properties

Cleanroom wall panels are usually made of PVC or PP materials, which have good conductivity and can effectively avoid the generation of static electricity and prevent the deposition of dust and microorganisms.This feature makes the wall panels particularly suitable for environments that require high cleanliness, such as medical, biopharmaceuticals and precision electronics.

(2) Corrosion resistance

The surface protective layer of the cleanroom wall panels has an anti-corrosion effect and can resist erosion by chemicals such as acids and alkalis. For example, the medical clean panel uses asbestos-free calcium silicate panel as the substrate, with a UV paint coating on the surface. It has good resistance to acid and alkali erosion and can resist erosion by organic solvents, disinfectants and other substances.

(3) Environmental performance

Cleanroom wall panels are usually made of PVC or PP materials, which do not contain heavy metals and other harmful substances, making them non-toxic and odorless, and meet environmental protection requirement. For example, medical clean panels are made of asbestos-free calcium silicate panels, which are non-toxic and harmless and can effectively reduce indoor pollution and bacterial growth.

(4) Easy cleaning property

The surface of the cleanroom wall panels is smooth and flat, does not stick to dust and is easy to clean. For example, the surface of the medical clean panel is smooth and rigid, germicidal and not easily stained, very easy to clean and maintain.

(5) Sound insulation property

Cleanroom wall panels have good sound insulation performance and can provide a more comfortable indoor environment. For example, medical cleanroom panels can still maintain their beauty and practicality in a humid environment and have good moisture and mildew resistance.

(6) Other properties

Cleanroom wall panels also have the characteristics of fire resistance, antibacterial and good durability. For example, medical cleanroom panels meet the A1 fireproof material standard requirements and can effectively prevent the spread of fire; the surface UV coating layer is dense and non-porous, and has excellent waterproof and moisture-proof capabilities.

According to the manufacturing process, cleanroom wall panels are divided into handmade purification sandwich panels and machine-made purification sandwich panels.

（1）Machine-made panel‌: It is produced through machine assembly lines and uses advanced machinery and equipment to complete the entire production process. It has the characteristics of high surface flatness, uniform color and texture, good sound insulation and heat insulation properties, and high strength and durability. Such panels are suitable for places with high requirements for sound insulation and heat insulation performance. Common application industries include:

♦ Electronic manufacturing

♦ Biopharmaceuticals

♦ Food processing

♦ Laboratory environment

♦ Medical Industry

♦ Electronic manufacturing field

♦ Food processing
