In the membrane separation technology applications, microporous membrane is the most widely used a variety of membrane varieties, the use of simple and quick. With strong gas flux, high particle retention rate, good temperature resistance, strong acid, alkali, organic solvents and oxidants, anti-aging and non-stick, non-flammable and non-toxic, good biocompatibility and so on. The material is divided into organic and inorganic two categories, in view of the separation characteristics of microporous membrane, microporous membrane application range is mainly from the gas phase and liquid phase retention of particles, bacteria and other pollutants to achieve purification, separation, Concentration purpose. For microfiltration, the film retention characteristics are characterized by the pore size of the membrane, usually pore size range of 0.1 ~ 1μm, so the microfiltration membrane can be large diameter bacteria, suspended solids and so on. Can be used as a general liquid clarification, security filter, air sterilization. Widely applied research, medicine and health, biochemistry, food, energy, microelectronics industry, nanotechnology, environmental protection and other departments.
