Ultrafiltration membranes are divided into plate and frame type (plate type), hollow fiber type, nanomembrane surface ultrafiltration membrane, ptfe tubular ultrafiltration membrane, roll type and other structures. Among them, hollow fiber ultrafiltration membrane is a relatively mature and advanced form of ultrafiltration technology. The outer diameter of the hollow fiber is 0.4-2.0mm, and the inner diameter is 0.3-1.4mm. The hollow fiber wall is covered with micropores. The pore size is expressed in terms of the molecular weight that can intercept substances, and the molecular weight interception can reach thousands to hundreds of thousands.
There are many materials on the market that can be used to make ultrafiltration membranes, which are divided into two categories: organic polymer materials and inorganic materials. Among them, organic polymer materials include cellulose esters, polysulfones, polyolefins, fluorine materials ptfe tubular ultrafiltration membrane, polyvinyl chloride, etc. Inorganic materials are new types developed in recent years. Membrane-making materials mainly include ceramics, glass, alumina (Al2O3), zinc oxide (ZnO2) and metals. Currently, they are still in the laboratory research stage in China and have not yet been commercialized. The outstanding advantages of ultrafiltration membranes made of this material are It has good temperature resistance and organic solvent resistance, is not easy to age, has strong reproducibility, and is suitable for special separations.
is a manufacturer specializing in the production of ptfe tubular ultrafiltration membrane. We have the characteristics of “uniform, stable, low resistance” in the field of industrial sewage treatment. , long life, customizable, easy cleaning and maintenance, etc., and the processing process has no phase change, has no adverse effects on the components in the material, and avoids the disadvantage of high temperature destroying biologically active substances, and is accepted and loved by the majority of enterprises. .
PTFE membrane technology has always been the core of the business and plays an indispensable role in many fields such as biopharmaceuticals, equipment, food and beverages, semiconductor manufacturing processes, and communications. Role, the pore-forming ability ranges from 0.1μm to 1μm, providing functional solutions such as fine filtration, removal of small bacteria and viruses, hydrophobic breathability, and sound transmission.
