Product introduction
Wear resistant zirconia ceramic lining brick refers to a kind of wear resistant products whick use alumina and zirconia as the main material. Compared with the alumina linging brick, wear resistant zirconia ceramic lining brick is more ductile due to the addition of zirconia. Titan produces wear resistant zirconia ceramic lining brick of different sizes and contents which can meet different customers' needs.
Advantage
1. High hardness, good wear resistance, light weight, specific gravity 4.2g/cm3, greatly reducing equipment load;
2. The bonding is firm and has good heat resistance. It is pasted on the inner wall of the equipment with heat-resistant glue. It can be used at 350°C Long-term operation without aging, the inorganic adhesive used for cemented products is wear-resistant at 750°C, and the adhesive is resistant to Strong temperature performance and adhesion performance;
3. Strong impact resistance, combined with zirconia toughness and wear resistance, the fracture toughness is comparable to that of alumina products Increased by 20%, bending strength increased by 70%, greatly improving the impact of materials on equipment;
4. High cost performance, which greatly increases the service life of the equipment and reduces the comprehensive production cost of the enterprise.
Application
Wear resistant zirconia ceramic lining brick is mainly used as liners of ball mill and transportation equipments, which can greatly reduce the wear of the equipments and prolong its service life.
