Generally speaking, the principle of a membrane filter is very simple. The solution to be filtered passes through a thin microporous membrane. Its permeability depends on the size of the pores, which is equivalent to the mesh size of an ordinary sieve and has smaller pores than the filter membrane. Small particles pass through the filter membrane, while particles larger than the pores of the filter membrane are trapped.
As for the Teflon liquid filtration membrane we are going to introduce today, its filtration effect is even more outstanding? Membrane water treatment is a solid-liquid separation technology. It filters water through membrane pores and intercepts impurities in the water. There is no chemical change and the process is simple, but because the membrane pores are very small, there are certain technical problems.
Biofilm is also used to treat raw water in water supply, but it is different from filtration membrane separation technology.
The membrane used for membrane separation is called membrane, and the membrane used for biofilm treatment is called film. Teflon liquid filtration membrane has wide applicability, stable chemical properties, high temperature resistance, corrosion resistance, water repellency, oleophobicity, etc. Therefore, it also has good filterability for special gases with high temperature, high humidity, high corrosion and organic liquids.
It is widely used in food and beverage, industrial wastewater, pharmaceutical fields, electronic appliances, etc.
The Teflon liquid filtration membrane processed through biaxial stretching technology gives the membrane good void characteristics. After the membrane is stretched in different directions, the structure of the micropores and agglomeration of the membrane changes, and at the same time the membrane The mechanical properties have anisotropic characteristics.
Because of its wide operating temperature range, small friction coefficient, stable chemical properties, low surface energy, microporous structure and other characteristics, it is widely used in environmental protection and chemical industry fields such as air dust removal, air sterilization, and water filtration.
