Description
Mosaic alumina ceramic tiles are made of alumina or zirconia calcined at high temperature. Alumina is converted into dense alpha alumina at high temperature, and due to its special crystal structure, it becomes extremely hard, second only to diamond in hardness. The wear resistance is much higher than that of any other material, in addition, due to the smooth surface of mosaic alumina ceramic linings pieces, the surface resistance is very small, which also greatly improves its wear resistance.
Product Advantages
High hardness: the Rockwell hardness of mosaic alumina ceramic linings pieces is above HRA90, the hardness is second only to diamond, far exceeding the wear-resistant performance of wear-resistant steel and stainless steel.
Excellent wear resistance: its wear resistance is 30 times that of manganese steel and 20 times that of high-chromium cast iron. According to the customer follow-up survey for more than 20 years, under the same working conditions, the service life of the equipment can be extended by at least ten times.
Light weight: its density is about 3.6g/cm³, which is only half of that of steel, which can greatly reduce the load of equipment.
Strong bonding and good heat resistance: The wear-resistant ceramic sheet can be fixed on the inner wall of the equipment by various methods such as gluing, welding, and rubber vulcanization according to different equipment and working conditions.
Corrosion resistance: good corrosion resistance to sulfuric acid, hydrochloric acid, strong alkali, salt, etc.
Application
Widely used in thermal power, thermal power, steel, heat, cement, smelting, mining, chemical, machinery, paper, aluminum and other industries with severe wear and tear.
