The sudden “popularity” of clean room FFU filter membranes stems from its ultra-efficient filtration ability. It has many properties and advantages that ordinary filter materials do not have. Today we will study this material.
Clean room FFU filter membrane is a microporous film produced using polytetrafluoroethylene dispersion resin through special processes such as premixing, extrusion, calendering, and biaxial stretching.
The surface morphology of the microporous film is a spider web-like microporous structure.
Pores are formed between the microfibers, and the arrangement direction of the microfibers is basically parallel to the stretching direction; the junction of the fiber bundles is the node, which is formed by the entanglement of many microfibers.
Fluorine element has the following characteristics: non-stickiness, heat resistance, corrosion resistance, low gas permeability, low refractive index, electrical insulator, antifouling, water and oil repellency, lubricity, low pollution, weather resistance, etc. , is an element with extremely high reactivity and is widely used in cutting-edge and traditional industries such as machinery, electronics, chemicals, military industry, aerospace, office automation equipment, semiconductors, and household products.
In industry, chloroform is used as raw material, chloroform is fluorinated with anhydrous hydrofluoric acid, the reaction temperature is above 65°C, antimony pentachloride is used as the catalyst, and finally tetrafluoroethylene is produced by thermal cracking method; Tetrafluoroethylene can also be produced by reacting zinc with tetrafluorodichloroethane at high temperatures.
We are a manufacturer specializing in the production of clean room FFU filter membrane materials. In the field of industrial sewage treatment, we have the characteristics of “uniform and stable, high efficiency and low resistance, long life, customizable, easy cleaning and maintenance” and are accepted by the majority of enterprises and favorite.
