Many companies will build purification workshops. Purification workshops can exclude particulates, harmful air, small bacteria and other pollutants in the air within the space, and remove indoor pollutants. Temperature, cleanliness, etc. are controlled within corresponding ranges. The editor will mainly talk about FFU and FFU filter materials in the purification workshop – Polytetrafluoroethylene filter paper.
FFU fan purification unit is light in weight and adopts a cover-type installation method, making installation, filter replacement and maintenance more convenient. Shorten the construction cycle. The FFU fan filter unit system saves significant energy, thereby solving the shortcomings of centralized air supply due to the large air-conditioning room and increased operating costs of the air-conditioning unit. The independent structural features of FFU can be adjusted at any time to make up for the lack of mobility in the clean room, thus solving the production process Disadvantages that cannot be adjusted. The use of FFU circulation system in clean rooms not only saves operating space, has high cleanliness reliability and low operating costs, but also has high operational flexibility. System upgrades and adjustments can be made at any time without affecting production, which can be very good. To meet the needs of clean rooms, the use of FFU circulation systems in semiconductor or other manufacturing industries has gradually become the main clean design solution.
Polytetrafluoroethylene filter paper is suitable for various purification workshops from level 1 to level 100,000. It adopts special processing technology. A microporous film made by calendering, extrusion, biaxial stretching and other methods. This polytetrafluoroethylene filter paper has excellent air permeability, corrosion resistance, aging resistance, temperature resistance and other properties. According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
