The development of modern science and technology is becoming more mature, and many membrane materials have become available.
Among them, ptfe high-temperature membrane with lower resistance and higher efficiency has been continuously developed and put into use.
At present, the high-temperature filter fibers used for flue gas treatment at home and abroad mainly include PPS (polyphenylene sulfide), Nomex (aromatic polyamide), P84 (polyimide), PTFE (polytetrafluoroethylene), Glass fiber and PSA (aromatic sulfone) fiber, etc., are often used in practical applications.
The production process includes needle felt, surface coating, emulsion impregnation, etc., which can achieve the effects of surface filtration and gradient filtration. It not only improves the dust collection capacity, but also reduces pressure loss, makes it easy to clean dust, and saves energy consumption.
PTFE high temperature film has excellent high temperature resistance and low temperature resistance. The melting point is 327 degrees Celsius and the decomposition temperature is 415 degrees Celsius. It can be used for a long time in the range of 200 to 260 degrees Celsius.
But a major disadvantage of PTFE is its immobility at high temperatures F.
It will not change from a high elastic state to a viscous flow state when it is above the melting point, and will not flow even if it is heated to the decomposition temperature, which makes it impossible to adopt the molding method of general thermoplastic materials.
PTFE has a low thermal conductivity and poor thermal conductivity.
It is a fluorine material film manufacturer integrating production, sales and customization.
The company has advanced PTFE high-temperature 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.
