What is the pore size of ptfe air filter membrane
There are many types of filter materials currently on the market, and they are widely used in the field of air filtration. However, existing air filtration materials generally have shortcomings such as thick diameter, large pore size, and low porosity. As a result, they still face limitations such as thick materials, single stacking structures, and difficulty in synchronous optimization of filtration efficiency and air resistance, which seriously limits the application performance of the materials. substantial improvement. In order to solve this problem, ptfe air filter membrane was born.
The forklift air filter can also be called the forklift air filter element or the forklift air grid. Its main function is to be installed on the air inlet of the forklift carburetor to remove the chemical that enters the forklift. Remove suspended dust and other unclean substances in the air of the oil collector to extend the service life of forklift engine parts.
There are two main methods for preparing PTFE air filter membranes that have been reported so far. One is to add the pore-forming agent NaCl to ptfe, then make the ptfe into a film, and then remove the NaCl by heating and washing with water. The vacancies left by the NaCl form pores. The minimum pore size of the microporous film made by this method is 0.1 μm. . The second is the mechanical stretching method. The microporous film made by the modified method has a special structure of island-like “knots” connected by microfibers. It is currently the main method for preparing PTFE microporous films.
