Silicon carbide has many uses. What are the specific uses? Let's give you a brief introduction:
(1) Mechanical seal ring silicon carbide: it is used for many purposes in machinery, but the main purpose of silicon carbide is to make silicon carbide seal ring. Silicon carbide ceramic has good chemical corrosion resistance, high strength, high hardness, good wear resistance, small friction coefficient and high temperature resistance, so it is an ideal material for making seal ring. When combined with graphite materials, its friction coefficient is smaller than that of alumina ceramics and cemented carbide, so it can be used in high PV value, especially in the working condition of conveying strong acid and alkali.
(2) Silicon carbide atmospheric pressure sintered products: silicon carbide atmospheric pressure sintered products have the characteristics of high density, high hardness, large production batch and can produce products with complex shapes. They are suitable for high-performance seals, especially under the working conditions of high PV value and resistance to strong acid and alkali. Because there are a large number of dispersed fine graphite particles in the silicon carbide matrix, when paired with other materials, its friction coefficient is very small and has good self-lubricating performance. It is especially suitable for making gas seals or seals with dry friction conditions, so as to improve the service life and working reliability of seals.
