0.45um microporous filtration membrane belongs to a category of PTFE bubble point membrane. The reason why it is called bubble point membrane is because it has been used to make bubble points. test.
Bubble point testing is based on the capillary model. The structure of the filter membrane is filled with microporous flow channels. These microporous flow channels form many “capillaries”. When the filter membrane is wetted by the wetting liquid, the liquid is retained inside the filter membrane due to surface tension. If To squeeze the liquid out of the membrane holes, an external gas pressure is required. The small pressure required to overcome the surface tension and squeeze out the liquid in the membrane pores is the bubble point pressure of the filter membrane, which is what we often call the bubble point. The test method based on this principle is the bubble point. Test method.
0.45um microporous filter membrane has two differences: hydrophilic and hydrophobic. The filtration precision can be adjusted to obtain different bubbles. pressure to meet the needs of different customers for different filtration precisions. High biological reliability, pore size between 0.1μm and 1μm. It can intercept almost all small bacteria and other impurities. It has strong chemical properties and is resistant to strong acids and alkalis. It has high porosity and interception rate, stable performance, and high air permeability despite high filtration effect.
It is a 0.45um microporous filtration membrane manufacturer that integrates production, sales and customization. The company has advanced PTFE film production lines and composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that it puts the interests of users first and provides users with high-tech, high-quality, high-performance, and high-level products.
