Hydrophilicity is defined as hydrophilicity. Hydrophilic ptfe hydrophilic filter membrane usually has a special chemical layer that allows the filter membrane to be wetted by water. ;Hydrophobicity is a reference to the repulsion of water. Hydrophobic membranes rarely absorb water at all. From the observation, it can be seen that the small water droplets stay on the surface of the filter membrane without being adsorbed by the surface and spreading into the water surface. The size of hydrophobicity depends on the pore size of the filter material and the characteristics of the filter membrane material.
Microporous filter membrane is made of polymer chemical materials, porogenic additives are specially treated and then applied to the support layer. become. In the application of membrane separation technology, microporous filtration membrane is a membrane type with a wide range of applications. It is simple and fast to use and is widely used in many fields such as scientific research, food testing, chemical industry, nanotechnology, energy and environmental protection.
At present, the ptfe hydrophilic filter membrane series independently developed by polytetrafluoroethylene membrane manufacturers is widely used in organic solvent filtration and has There are two categories: hydrophobic and hydrophilic. It can achieve sterility when used for gas filtration, has the characteristics of large flux, temperature resistance, resistance to strong acids and alkalis, and wide chemical applicability. It is suitable for fermentation tanks, carbon dioxide, nitrogen and compressed air. When used for liquid filtration, it can intercept all kinds of phages, small bacteria and particles above 0.2μm, meeting the requirements of HIMA small bacteria interception experiments.
ptfe hydrophilic filtration membrane technology has always been the core of the business, in biopharmaceuticals, equipment, food and beverages, semiconductor processes, It plays a very important role in many fields such as communications. Its pore-forming capacity ranges from 0.1μm to 1μm, providing functional solutions such as fine filtration, removal of small bacteria and viruses, hydrophobic breathability, and sound transmission.
