Product Description:
The silicon carbide push plate is mainly composed of silicon oxide and silicon carbide. The oxidation of silicon carbide is more obvious above 1300 ℃.The current large application field is the positive electrode of lithium battery. Material pusher kiln, inorganic powder calcination pusher kiln, etc.
Silicon carbide push plate is made of highpurity silicon carbide ceramic material, which has high hardness, high strength, high temperature stability and excellent wear resistance. It also has excellent chemical stability and good resistance to corrosive media such as acids and alkalis.
It has a lower density compared to metal materials, thus enabling lightweight designs. Despite this, it is very strong, capable of withstanding high pressure and mechanical stress, and is suitable for applications requiring high strength and lightweight construct
Features:
1.Excellent fire resistance: It has excellent fire resistance, can work stably for a long time at high temperature, and will not be corroded by flame, high temperature gas and molten substances.
2.Chemical corrosion resistance: It has good resistance to corrosive media such as acid and alkali. In some kilns or chemical reactors that need to deal with corrosive substances, silicon carbide push plates can provide effective protection
3.Excellent thermal conductivity: Silicon carbide push plate has excellent thermal conductivity, which can transfer heat quickly and achieve uniform heating or cooling.
