Alumina or zirconia are calcined at high temperature to make wear-resistant ceramic linings. Alumina can be transformed into dense alpha alumina at high temperature. Due to its special crystal structure, it becomes extremely hard, second only to diamond in hardness.
The wear resistance of the alumina wear-resistant lining is several times or even more than that of other wear-resistant materials. In addition, due to the smooth surface of the wear-resistant ceramic lining, the resistance is very small, which can greatly improve the wear resistance.
Features:
(High hardness) The Rockwell hardness of alumina wear-resistant ceramic sheet is above HRA90, the hardness is second only to diamond, far exceeding the wear-resistant performance of wear-resistant steel and stainless steel.
(Good wear resistance) The wear resistance of alumina wear-resistant ceramic sheet 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) The density of the alumina wear-resistant ceramic sheet is about 3.6g/cm³, which is only half of that of steel, which can greatly reduce the load of the equipment.
(Good adhesion 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.
(strong corrosion resistance) has good corrosion resistance to sulfuric acid, hydrochloric acid, nitric acid, strong alkali, salt, etc.
