04 Anti bacterial
The rapid multiplication of bacteria in membrane pore is an important cause of membrane pore pollution.By modifying the material of membrane and adding antibacterial components in PVDF alloy,JF reinforced membrane products prevent bacteria from multiplying in the membrane pores and greately reduce the rate of biological pollutaion in the membrane pores.

05 High Strength
The improvement of membrane physical strength can increase the service life of the material of membrane.JF reinforced membrane products improve the peeling strength between the filter layer and reinforced layer by modifying the surface of reinforced material.The bursting pressure of reinforced membrane product is higher than 0.8Mpa,the tensile strength is more than 400N.
