SiC Mechanical Seal
Silicon carbide products are classified into many kinds according to different application environment. It is generally used more mechanically. For example, silicon carbide is an ideal material for silicon carbide mechanical sealbecause of its good chemical corrosion resistance, high strength, high hardness, good wear resistance, small friction coefficient and high temperature resistance.
Silicon Carbide SealMaterial
Silicon carbide (SiC) is also known as carborundum, which is made of quartz sand, petroleum coke (or coal coke), wood chips (which need to be added when producing green silicon carbide) and so on. Silicon carbide also has a rare mineral in nature, mulberry. In contemporary C, N, B and other non-oxide high technology refractory raw materials, silicon carbide is one of the most widely used and economical materials, which can be called gold steel sand or refractory sand. At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a proportion of 3.20 ~ 3.25 and microhardness of 2840 ~ 3320kg/mm2.
Types of Silicon Carbide Seal Rings
SiC Sealrings can be divided into static ring, moving ring, flat ring and so on. SiC silicon cab be made into various carbide products, such as silicon carbide, silicon carbide, silicon carbide ring and so on, according to the special requirements of customers. It can also be used in combination with graphite material, and its friction coefficient is smaller than alumina ceramic and hard alloy, so it can be used in high PV value, especially in the condition of strong acid and strong alkali.
