Common materials of fiber sealing gaskets include aramid fiber, aluminum silicate fiber paper and ceramic fiber.
Aramid fiber
Aramid fiber sealing gasket is made of high-strength aramid fiber, which has excellent high temperature resistance and can remain stable even in extreme environments. It does not contain asbestos, is environmentally friendly and safe, and is particularly suitable for scenes with strict health and environmental requirements. For ships that need to replace seals frequently, the durability of aramid fiber gaskets is very outstanding, which can effectively reduce the risk of leakage and extend the service life.
Aluminum silicate fiber paper
Aluminum silicate fiber paper is made of loose cotton as the main raw material, with a very small amount of inorganic or organic binder added, and refined through a wet forming process. It has the following advantages: High temperature resistance: It can maintain structural stability in high temperature environments, is not easy to deform or damage, and ensures the durability of the sealing effect. Low thermal conductivity: It can effectively prevent the transfer of heat and keep the temperature of the sealing area stable. Thermal shock resistance: It can withstand rapid temperature changes without breaking. High temperature insulation performance: Ensure electrical safety in high temperature environment.
Anti-nonferrous metal molten erosion ability: Able to resist molten erosion of nonferrous metals such as aluminum and zinc.
Non-toxic and harmless: No adverse effects on the environment, in line with environmental protection requirements.
Ceramic fiber
Ceramic fiber gaskets are mostly made of natural kaolin melted in an arc furnace and then sprayed or resistance polished. Its characteristics include:
High temperature resistance: Continuous use temperature can reach 1000℃, short-term use temperature can reach 1260℃.
Acid and alkali corrosion resistance: Has good acid and alkali corrosion resistance and resistance to molten metal corrosion such as aluminum and zinc.
High temperature strength: Good high temperature strength and excellent thermal insulation performance.
Electrical insulation performance: Electrical insulation performance is higher than glass fiber.
Non-toxic and harmless: Non-toxic, harmless, and odorless.
