Wear resistant ceramics are special corundum ceramics that use AL2O3 as the main raw material, rare metal oxides as flux, and are roasted at a high temperature of 1,700 degrees. They are then combined with special rubber and high-strength organic/inorganic binders. The product.
Now alumina wear-resistant ceramics have spread all over the market and are widely used in steel, coal, thermal power, cement, smelting and other industries. So how to choose wear-resistant ceramics?
1. Hardness of wear-resistant ceramics
Generally used in various equipment, people often choose wear-resistant ceramic sheets, which are directly attached to the surface of the equipment to protect the equipment from wear. Due to the small size of the ceramic sheets, they can be flexibly applied to equipment of various shapes. Different equipment uses ceramics with different hardnesses, which are determined based on the working conditions.
2. Wear resistance
Special working conditions require the use of more wear-resistant ceramics, such as ZTA toughened alumina ceramics. ZTA toughened alumina ceramics add certain zirconia ceramic ingredients on the basis of alumina. The wear resistance and toughness are between alumina ceramics and zirconia ceramics. ZTA ceramics have better wear resistance than 95% alumina ceramics. good.
3. Working temperature
Secondly, the operating temperature of the equipment must be considered, which determines the choice of installation method of wear-resistant ceramics to ensure that the wear-resistant ceramics can not fall off under high temperature conditions. If bulk materials are transported, the impact intensity must be evaluated based on factors such as material properties, particle size, drop, erosion angle, etc. to ensure the selection of appropriate wear-resistant ceramics.
