Many well-known, covered needle felt is widely used in municipal waste incineration dust collection, chemical dust and other adverse conditions. It is resistant to acids, alkalis, and corrosive gases and has high filtration accuracy. It is the ideal waste incineration dust bag. But how much do you know about a specific point? Xiao Bian is here today for everyone to explain in detail.
The specific features are as follows:
1.Physical properties
Smooth surface, almost no water absorption, low permeability to water vapor. The
2. Low coefficient of friction
The friction coefficient of PTFE is the smallest among solid materials to date. The
3. Extremely high heat resistance
Operating temperature range: -200–260 °C. The thermal stability of PTFE is the highest among thermoplastics. It does not lose its self-lubricity at low temperatures, it has high strength, and it has flexibility at -80°C. The
4. Chemical resistance
PTFE fibers are resistant to many highly corrosive media and are virtually unaffected by any chemical (except for alkali metals and alkaline-earth metals and their compounds above 350°C that are corrosive). Not affected by moisture, mildew, bacteria, ultraviolet rays, etc. The
5. Good electrical conductivity
In addition to poor corona resistance, PTFE fiber is the most excellent dielectric material
