Several materials of common folding filter element

The main characteristics of foldable filter element are: high rejection, high flux, low pressure difference and wide chemical compatibility; the production process adopts unique hot-melt welding processing technology, without any adhesive and foreign matters Meet the production requirements of food, beverage, beer, chemical, pharmaceutical and other industries Common folding filter elements are mainly made of the following materials: 1 PP membrane is a kind of membrane material which is made of polypropylene Microfiber by hot-melt adhesion and belongs to deep filtration It has the following characteristics: taking food grade isotactic polypropylene as raw material, there is no additive in the whole process of production; its physical and chemical properties are stable, and it has good phase compatibility; it has a series of pore diameter, high porosity, large pollutant holding capacity, recoil and high temperature disinfection; Good pressure resistance 2 PTFE membrane: it is a microporous membrane produced by using polytetrafluoroethylene dispersion resin and special processes such as premixing, extrusion, calendering and biaxial stretching It is divided into garment membrane, Pu micro waterproof membrane, filter membrane and purification membrane   3 PES membrane, which is made of polyethersulfone microfiber by hot-melt adhesion, is a kind of membrane material for deep filtration It has the following characteristics: taking food grade isotactic polypropylene as raw material, there is no additive in the whole process of production; its physical and chemical properties are stable, and it has good compatibility; it has a series of pore diameter, high porosity, large pollutant capacity, recoil and high temperature disinfection; Good pressure resistance 4 Nylon membrane and the membrane filter material synthesized by cellulose ester have been widely used by relevant units for many times, and the quality meets the standard The product has smooth surface, light and thin texture, high porosity and even microporous structure, so it has the characteristics of fast flow rate and not easy to adsorb Nylon N6 / n66 membrane is a kind of microporous membrane with support, high strength, high precision and good hydrophilicity, which is produced by nylon N6 / n66 solution through mutual conversion of advanced production process 5 PVDF membrane: it is made of PVDF solution in the support layer by advanced production process It has a wide range of pH resistance and is a microporous membrane for good gas and organic liquid filtration.
