How Much Do You Know About Wear-resistant Alumina Ceramic Linings
What is Wear-resistant Alumina Ceramic Lining?The alumina ceramic wear-resistant coating is made from a special corundum material formed by Al2O3 in the main raw materials and a rare metallic oxide as a solution. This ceramic is then calcined with a high temperature (1700 degC).
There are many different types of wear-resistant alumina tiles, such as high-aluminum sheets, wear-resistant ceramics linings. alumina patches and alumina linings.
What are some of the benefits and features of ceramic alumina linings that resist wear?
Wear-resistant Alumina Ceramic Lining Features: First, its hardness is high. Rockwell hardness can reach HRA80 to 90. Second, its wear resistance, which is higher than that of manganese and high-chromium cast-iron, can extend the life of equipment by more than tenfold. Third, it is light and its density of 3.65g/cm can reduce the weight of the equipment. Fourth, the wear resistant alumina lining adheres firmly and is heat-resistant. It is a good performer, and can be used for a very long time in temperatures up to 350 degrees Celsius without aging.
Wear-resistant Alumina Ceramic Lining: It is an inorganic, non-metallic, material that will not pollute the atmosphere. It has a high level of toughness, seismic performance, and fracture toughness. Wear-resistant ceramic lining has a high mechanical strength, good compatibility and integrity. It can effectively stop breakage and peeling due to impact force.
How can I identify wear-resistant alumina linings?
Look at the surface of ceramic sheet first. The surface is uniformly colored, smooth, and free of black spots. After vulcanization the ceramic wear-resistant lining is attached to background paper. The joints will be continuously shaped into a straightline. They can be identified through measuring their density. Density can be measured to calculate the alumina. The test can be performed using a 50mm distance, a sandblaster at a pressure 4.0 kg/cm3, and a 45° spray angle. Gradient, time-measured wear within 60 minute.
Can wear-resistant ceramic alumina linings be applied in these industries?
Wear-resistant alumina linings are used in power, metallurgy (including coal), petroleum, chemical, machinery, and other industries. The material should be safe and reliable to use for high-temperature corrosion, high-temperature wear or high-temperature ablation. The data shows that the wear-resistant materials have a ten-to-twenty-fold higher life span than cast stone or steel alloys cast in alloy, rubber and steel.
