芳綸覆膜

     PTFE覆膜針刺氈是在普通濾料表面復合一層聚四氟乙烯薄膜而成的一種新型濾料。覆膜濾料表面光滑而且耐化學物質，過濾時能將粉塵全部截留在膜的表面，可實現(xiàn)表層過濾。覆膜針刺氈具有剝離強度高、透氣量大、阻力小、孔徑分布集中均勻等特點，能有效地截留以萎靡來計算的抄襲粉塵，除塵效率達99.99%以上。

      PTFE membrane felt is a kind of filter material, which is coated with polyterafurcethylene membrane on its surface.The surface of PTFE membrane felt is smooth and anti-chemistry.It can stop dusts getting into inner, and surface filter can be realized. Compared with normal filter material, PTFEE membrane felt has highter peel strength and air permeability, lower pressure drop, and efficiently prevents ultrafine dust measured in microns. Filtration efficiency is up to 99.99%.
