PTFE microporous filter membrane is a material commonly used for liquid and gas phase filtration and separation. It is characterized by good chemical stability and temperature resistance. , corrosion resistance, wear resistance, good hydrophobicity, etc. The small pore size can achieve fine filtration and separation effects.
There are various preparation methods, including coating method, stretching method and self-assembly method. Among them, the coating method is one of the commonly used preparation methods. PTFE particles are mixed with a solvent to form a dense emulsion, which is then coated on the substrate and dried at high temperature to form a film. The stretching method is to heat the PTFE polymer to a semi-molten state, then stretch it into a film, and perform heat treatment and solidification. The self-assembly method uses PTFE surface tension and electrostatic force to make PTFE particles arrange themselves and form a film.
PTFE microporous filter membrane is widely used in food, chemical industry, electronics, environmental protection and other fields. It is used as a filter material for surgical masks, which can filter bacteria and viruses well to ensure the surgical process; in the food field, it is used to filter beverages, beer, etc. to remove impurities and harmful substances and ensure product quality; in the chemical industry, It is used to separate organic matter and water and purify chemicals; in the electronic field, it is used to prepare optical films and protect display screens.
In addition, it can also be used as a substrate for other functional films, such as nanocomposite films, anti-corrosion films, etc. At the same time, environmental pollution and resource waste are reduced through cleaning, recycling and reuse.
In general, PTFE microporous filtration membrane has wide application value and development prospects. With the continuous advancement of science and technology and With the improvement of the process, its performance and application fields will become more and more diverse and extensive.
