Filter material polytetrafluoroethylene microporous membrane manufacturer

Polytetrafluoroethylene microporous membrane is a polymer compound made of tetrafluoroethylene. It is a membrane material made by calendering, extrusion, biaxial stretching and other methods using a special process.

Characteristics: 1. High filtration efficiency, which can meet the filtration efficiency level requirements of sub-efficient, high-efficiency and ultra-high-efficiency air filters.

?2.?Compared with other high-efficiency filtration materials, polytetrafluoroethylene microporous membrane manufacturer membrane materials have a higher PF value and good filtration performance.

(PF value represents an indicator of the balance between filtration efficiency and pressure loss. The larger the PF value, the better the filtration effect. The calculation formula is as follows: ?PF value = -log (1-filtration efficiency) / pressure loss * 1000 Pressure loss unit: Pa, test flow rate: 5.3cm/s, particle size range: 0.1~0.2μm.

)? 3. The membrane pore size is small, and the material has undergone high-temperature heat setting treatment, and the microporous structure is stable, so it can effectively intercept dust particles at high wind speeds.

?4. PTFE material has strong hydrophobicity, low surface energy, and good non-adhesion. It is easy to remove dust accumulated on the surface of the material, so it can be rinsed with water to restore its performance, achieve reuse, and greatly extend its service life.

?5. Surface filtration mechanism, the accumulated dust can be easily removed through mechanical vibration or wiping.

Polytetrafluoroethylene microporous membrane manufacturers undertake various filter material coating processing services. Our company will perform coating processing according to the coating substrate provided by the customer or the coating substrate specified by the customer.

The key to its technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. Our company can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different needs of users.
