What kind of ceramic adhesive is used for wear-resistant ceramic liner
The wear-resistant ceramic liner is mainly made of alumina or zirconia, which has good electrical conductivity, mechanical strength and high temperature resistance, far exceeding the wear resistance of wear-resistant steel and stainless steel
The wear resistance of wear-resistant ceramic linings is recognized, and wear-resistant ceramic linings are widely used because of their simple installation, low cost, and saving maintenance time. However, in power plants and metallurgical plants, the temperature of the equipment is generally high, and the conventional wear-resistant ceramic glue is not resistant to high temperature (the high temperature can reach 150 ° C. Once operated at high temperature for a long time, the glue is easy to age, causing the ceramic to fall off.
The high-temperature wear-resistant ceramic adhesive is a two-component modified epoxy adhesive, in the form of white mud, which can be cured at room temperature. Heating curing can obtain better bonding strength of wear-resistant ceramic linings; the long-term temperature resistance after curing is 250 °C, High temperature resistance of 280℃; aging resistance, corrosion resistance, high strength, good toughness; strong initial viscosity, no magnets or other support measures during construction, and will not fall off, optimizing the construction process and reducing the construction cost. Used for self-adhesion and mutual adhesion of metal, cement, ceramics, wood and other materials, especially suitable for wear-resistant ceramic sheets (lining plates) on the surface of equipment below 250 °C, such as: wear-resistant ceramic lining plates at the outlet pipe of coal mills in thermal power plants , The inner shell of the powder discharge machine, the dust removal system of the steel plant, the air duct elbow, etc.
Wear-resistant ceramic linings are mainly used as wear-resistant materials for the inner walls of various industrial equipment, with high-purity alumina as the main raw material. It has obvious advantages such as high hardness, good wear resistance, strong impact resistance, light weight and good stability.
