Polytetrafluoroethylene is a material that has excellent chemical resistance and is resistant to all chemicals. It is known as the king of plastics.
At present, a series of filter materials made of PTFE liquid filter membrane are widely used in many fields such as garbage incineration and high-sulfur coal dust removal.
There are two main methods for preparing PTFE liquid filtration membranes.
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 microporous film made by this method has the smallest pore size. is 0.1μm.
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.
Have 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 everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
