PTFE material has a highly symmetrical structure, no active groups, high crystallinity, low surface energy, difficult surface wetting, and strong hydrophobicity. Only this kind of film has been specially treated Processing capabilities make its application range wider.
With the continuous expansion of the application scope of e-PTFE membrane, domestic and foreign researchers have conducted a lot of research on the surface modification of PTFE membrane, through plasma treatment , functional monomer polymerization, chemical treatment, sputtering and other treatment methods can improve its wettability and adhesion to increase its surface energy and adjust its hydrophilicity to becomepolytetrafluoroethylene hydrophilic filter membrane , Different from the hydrophobic properties of general e-PTFE microporous membranes, the modified e-PTFE microporous membrane can allow water to pass through, and the suspended particles in the water are separated, thereby expanding its use in water purification. ,, health and other industrial applications.
The currently independently developed PTFE bubble point membrane series is the core material of sterilization filters and has hydrophobic and hydrophilic properties. (Polytetrafluoroethylene hydrophilic filter membrane) Two categories. It has strong hydrophilicity and hydrophilic stability; no pre-wetting is required during use; good mechanical properties; temperature resistance; good anti-pollution properties; strong acid and alkali resistance. It is widely used in medicine, food, beverage, beer, chemical and other industries, such as filtration of sterile raw materials and liquid sterilization in the pharmaceutical industry, filtration of liquor, beverages, wine, fruit wine, etc. in the food industry, and organic solvents in the chemical industry. , various alcohols, chemical reagents, etc. filtration.
Polytetrafluoroethylene hydrophilic membrane has always been the core of business, in biopharmaceuticals, equipment, food and beverages, semiconductors It plays an indispensable role in many fields such as manufacturing and communications. Its hole-making capacity ranges from 0.1μm to 1μm, providing functional solutions such as fine filtration, bacteria and virus removal, waterproofing, breathability, and sound transmission.
