Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01μm, which can effectively remove water from water. Particles, colloids, small bacteria, heat sources and high molecular organic substances. It can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase transformation and operates at room temperature. It is particularly suitable for the separation of heat-sensitive substances and has good temperature resistance, acid and alkali resistance and oxidation resistance. It can be used continuously for a long time under the conditions of below 60℃ and pH of 2-11. use.
According to the classification of membrane materials, ultrafiltration membranes can be divided into organic membranes and inorganic membranes. According to the appearance characteristics of the membrane, ultrafiltration membranes can be divided into: flat membrane, ptfe tubular ultrafiltration membrane, inner diameter > 10nm, capillary ultrafiltration membrane, inner diameter 0.5 ~ 10.0nm, hollow fiber ultrafiltration Membrane, inner diameter <0.5nm, porous ultrafiltration membrane.
ptfe tubular ultrafiltration membrane is a polymer compound polymerized from tetrafluoroethylene. It is calendered and Membrane materials made by extrusion, biaxial stretching and other methods. It can well intercept dust particles in the air, and the material has strong hydrophobicity, non-adhesion, corrosion resistance, thermal stability and good mechanical properties, so it can be washed with water to restore performance, extend service life and save costs.
The ptfe tubular ultrafiltration membrane currently independently developed and produced is widely used in water treatment, with a pore size of 0.1μm-1μm. It is prepared using a two-way stretching process, which can ensure that all small bacteria and impurities are trapped. It can be used in liquid filtration to achieve sterility. It has wide chemical applicability, resistance to strong acids and alkalis, and high ozone strength.
