芳纶覆膜

     PTFE覆膜针刺毡是在普通滤料表面复合一层聚四氟乙烯薄膜而成的一种新型滤料。覆膜滤料表面光滑而且耐化学物质，过滤时能将粉尘全部截留在膜的表面，可实现表层过滤。覆膜针刺毡具有剥离强度高、透气量大、阻力小、孔径分布集中均匀等特点，能有效地截留以萎靡来计算的抄袭粉尘，除尘效率达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%.
