Polytetrafluoroethylene (PTFE) microporous membrane has been widely used in various industrial fields due to its special physical and chemical properties. In the automotive manufacturing industry, PTFE microporous membranes also play an important role in valve systems. This article will discuss in detail the application of PTFE microporous membranes in automotive valves.
1. Characteristics of PTFE microporous membrane
Polytetrafluoroethylene microporous membraneIt is made of polytetrafluoroethylene (PTFE) film that has been specially treated to form uniformly distributed micropores. This membrane has excellent temperature resistance, corrosion resistance and anti-stick properties, and can maintain stable performance over a wide range of temperatures and pressures.
2. Application of PTFE microporous membrane in automotive valves
Automotive valves are the It is an important part of the fluid control system, and its performance directly affects the operating efficiency and reliability of the vehicle. The application of PTFE microporous membrane in automobile valves is mainly reflected in the following aspects:
1. Valve sealing
In high-pressure hydraulic valves, PTFE microporous membranes are often used to seal the valve disc and valve seat. Due to the excellent corrosion resistance and anti-stickiness of PTFE microporous membrane, it can prevent oil leakage and extend the service life of the valve.
2. Valve stem seal
PTFE microporous membrane can also be used for automotive valves Rod seal. Under high pressure conditions, PTFE microporous membrane can provide good sealing effect and prevent oil leakage. At the same time, the excellent temperature resistance of the PTFE microporous membrane can also ensure the normal operation of the valve in high temperature environments.
3. Anti-pollution protection
With the development of automotive electronics, the development of automotive valves The usage environment is also becoming more and more complex. Contaminants such as fine dust and moisture may affect the performance of the valve. PTFE microporous membrane can well prevent the intrusion of these pollutants and protect the normal operation of the valve. Interested parties can enter the store for consultation and purchase!
