1、采用独特的糊膏挤出、双向拉伸技术,制得纤维直径可以达到100nm以下,具有高效低阻的特点。 2、PTFE纳米滤材的过滤机理是纯物理过滤,长期储存效率不会降低,安全可靠;使用沸
PTFE覆膜材料
Composite PTFE Membrane Filter Media Introduction
 
聚四氟乙烯(PTFE)材料具有优异的耐高温,抗化学品非粘附性和疏水性能,经双向拉伸工艺制备得到PTFE微孔膜,具有纤维交错排列的微孔结构,其孔隙率高,孔径小而均匀,因此,PTFE微孔膜在较低的阻力下就能获得较高的效率。
将上述PTFE微孔膜与聚酯纺粘布,水刺无纺布,针刺毡等骨架材料覆合在一起形成PTFE覆膜材料,提高其强度和挺度,满足后道应用要求。
 
Polytetrafluoroethylene (PTFE) material has excellent high temperature resistance, chemical resistance, non-adhesion and hydrophobic properties, prepared by the biaxial stretching technology to obtain PTFE porous film having a staggered fiber pore structure, high porosity, small and uniformpore diameter, therefore, PTFE porous membrane can be at a relatively low resistance to higher efficiency is obtoined. The above PTFE porousmembrane with a polyester spunbond, spunlace nonwoven, needle felt and otherreinforcing material laminafed together to form a PTFE composite material to improve its strength and sifness to meet application.
