The influence of asbestos fiber quality in mechanical seal:

The quality of asbestos fiber has a great influence on the 2100 mechanical sealing performance of asbestos rubber sheet. Therefore, it is required that the asbestos fiber has high tensile strength, good heat resistance, a certain length, and the fiber is easy to bend and be elastic. Because asbestos is a loose material, there are still a lot of pores inside after it is pressed into a sheet. A certain amount of rubber (as a binder) and various fillers must be added to make asbestos rubber sheets. Adding binders and fillers can be Fill pores and prevent leakage. Generally, asbestos fibers account for 60%-85%.

Asbestos rubber sheet has suitable strength, elasticity, softness, heat resistance and medium resistance. It is convenient and cheap to make gaskets, so it is widely used. The relevant standards are shown in Table 3-1.
