WATER FILTER OF DOMESTICS AND PROCESS FOR PREPARATION OF MEMBRANE FOR WATER

摘要

As a complex semi-permeable membrane, porous supporters are layered on the polyester fabrics on which surface forms an activated layer. As a polyester, zeolite in which copper etc is adsorbed is used. The additional copper is layered at the time of polyester polymerization or at the time of ejection to give anti-biotics. As an activated layer, the crosslinked polyamide type ultra thin membrane made by the condensing polymerization of a multi-functional amine solution and a multi-functional halogen material's solution. By completely drying up the hydrocarbon type solvent, the distribution of the compound micro-structure and the deterioration of the properties of the material are prevented.
