The principle of fiber sealing gasket is mainly based on its material properties and sealing mechanism. Fiber sealing gaskets are usually made of fiber materials (such as asbestos, glass fiber, etc.) and rubber or other elastic materials, and have good elasticity and resilience. Its sealing principle mainly includes the following aspects:
Material properties: Fiber sealing gaskets are usually made of fiber materials (such as asbestos, glass fiber, etc.) and rubber or other elastic materials. This composite material has good elasticity and resilience, and can deform when subjected to compression force to fill the tiny gap between the sealing surfaces.
Sealing mechanism: When the fiber sealing gasket is pressed between the two sealing surfaces, the gasket material will deform and fill the tiny gap between the sealing surfaces. As the compression force increases, the deformation of the gasket will also increase, thereby squeezing the surface layer of the gasket into the trough of the sealing surface to prevent the medium from penetrating from the interface. When the spacing between the sealing surfaces increases, the gasket has a rebound force, which can fill the change in spacing and prevent the medium from leaking.
