Wear-resistant ceramics are special corundum ceramics made of AL2O3 as the main raw material, rare metal oxides as flux, and calcined at a high temperature of 1,700 bai. The hardness is large, its Rockwell hardness is HRA80-90, the hardness is second only to diamond, and it exceeds the wear resistance of wear-resistant steel and stainless steel. It has excellent wear resistance and can extend the service life of the equipment by more than ten times. It is light in weight and its density It is only half that of steel, which can reduce the load of equipment, have firm bonding and good heat resistance. Wear-resistant ceramic sheets are best to be pasted with special wear-resistant ceramic sheet glue, which can ensure that the ceramics will not fall off for a long time at high temperatures. Then how to choose wear-resistant ceramic sheet glue, we can choose from the following points:
1. What material is the wear-resistant ceramic sheet bonded to, for example, the wear-resistant ceramic sheet is bonded to metal (stainless steel, aluminum alloy, titanium alloy, etc.);
2. How big is the bonding area;
3. The medium resistance of the glue after bonding, that is, the specific bonding requirements, such as bonding speed, colloid color, colloid viscosity, high and low temperature resistance, bonding strength, etc.;
For wear-resistant ceramic sheet adhesive, compared with general structural adhesives, it has high bonding strength, peeling resistance, abrasion resistance, chemical corrosion resistance, impact resistance, shock absorption and buffering, high temperature resistance and a wide range of applications. Instead of welding, riveting, bolting and other traditional connection methods, it can also be applied to the bonding of wear-resistant ceramic sheets on equipment such as steel, electric power, cement, mining, coal, and ports, and can be applied to wear-resistant ceramics under 200℃ Bonding of sheet to metal. Wear-resistant ceramic sheet glue is also suitable for the paste of wear-resistant ceramic sheets on equipment such as coal conveying and ash discharge systems in thermal power plants, as well as material conveying and batching systems in the metallurgical industry.
