As a Ceramic Slurry Pump Exporter, share it with you.
Silicon carbide (SiC) material is a mature wear-resistant material with high hardness, stable molecular structure, good wear resistance, corrosion resistance, and high temperature resistance. It has been widely used in mining, metallurgy, electric power, chemical industry, etc. industry. In the field of slurry pumps at home and abroad, the working conditions are mostly strong corrosive and abrasive media, and the use environment is harsh. This requires the material of the flow part to have good wear resistance and corrosion resistance. Silicon carbide ceramics (including Silicon nitride bonded silicon carbide sintered ceramics and resin bonded silicon carbide composite ceramics) are an excellent choice.
Ceramic Slurry Pump
Characteristics of silicon carbide ceramics:
1. Strong wear resistance of silicon carbide:
The crystal structure of silicon carbide is similar to that of diamond tetrahedron. It is a compound composed mainly of covalent bonds, and its hardness is second only to diamond. Through the comparison test of XAJD, its wear resistance is 3.51 times that of Cr30 wear-resistant steel.
2. The strong corrosion resistance of silicon carbide ceramics
It has good chemical stability, can withstand the corrosion of almost all inorganic acids, organic acids and alkalis, and has excellent oxidation resistance.
Ceramic slurry pump, suitable for mining, metallurgy, electric power, coal, chemical industry, building materials and other industries, transporting abrasive and corrosive slurry containing solid particles, such as power plant ash transportation, coal slurry transportation, metallurgical concentrator slurry transportation, coal washing Plant coal slurry and heavy-medium transportation, etc. The maximum weight concentration of the solid-liquid mixture: 45% mortar and 60% ore slurry.
