1. Flexible PVC sheets and semi-rigid PVC sheets are commonly used in the air. They are flexible, wear-resistant, dustproof, easy to clean, corrosion-resistant, anti-static and beautiful. However, the quality of joints and stickers runs out of control, which will affect the application effect. They are suitable for electronics, fine manufacturing of ordinary clean rooms and pharmaceutical industry. Less.
2. Terrazzo in the air has good integrity, lubrication, wear resistance, not easy to dust, easy to clean, anti-static, no elasticity and other characteristics. However, due to practical data and construction quality easily out of control, it is less used in electronic products consumption, comparable to applicable to food, cosmetics, general API industry.
3. Coating type air is divided into polyurethane coating and epoxy resin or polyester resin mortar, cement air, polyurethane coating at room temperature dry curing, and metal, concrete and other good adhesion, easy to construct, with a bright appearance, good elasticity, easy to clean, water resistance, oil resistance, corrosion resistance and wear resistance, etc., in the epoxy or polyester resin to participate in hardeners, pigments. The coating construction method or tape test method (i.e. self-leveling) or cement construction method has the advantages of convenient construction, corrosion resistance, water resistance, good mechanical strength, impact resistance, clean and beautiful appearance. If antistatic materials are added, good electrical conductivity, etc., it is most commonly used in the air of Dongguan Dustless Workshop at present.
4. The metal sandwich ventilation floor is used in the vertical single-flow purification workshop as a return air barrier. It is usually made of porous plates, which are joined together by perforations of several moving units. It is arranged in the corresponding supporting structure. The number, opening rate and device location of the porous plates should be determined according to the air velocity and air volume of the single-flow dust-free workshop. Usually, the opening rate of the porous plates is about 6%-40%, which is mainly composed of porous plates. Applicable to electronic industry.
