Wear resistant ceramic characteristics and technical indexes
1, the wear-resisting ceramics definition and performance characteristics
The definition of wear-resisting ceramics:
Wear-resisting ceramics is AL2O3 as the main raw material, with rare metal oxide as the flux, through one thousand seven hundred baidu high temperature roasting of special alumina ceramic, with special rubber and high intensity of a combination of organic/inorganic adhesive products.
Wear resisting ceramics performance characteristics:
A high hardness
B, excellent wear resistance
C light weight (only half as much as that of the steel can greatly reduce equipment load)
D good adhesion strong, heat-resisting performance (wear-resisting ceramics piece of heat-resisting strong glue to stick on the inner wall of the equipment)
E Wide range of application
Thermal power, steel, metallurgy, machinery, coal, mining, chemical, cement, port terminals and other enterprises of coal transporting system, pulverizing system, ash discharge and dust removal system, etc
All wear large mechanical equipment, can choose according to different requirements of different types of products.
