How Much Do You Know About Wear-resistant Alumina Ceramic Linings
What is Wear resistant alumina ceramic lining (Alumina Ceramic Lining)?The wear-resistant alumina lining is made from a corundum special ceramic, which is formed using Al2O3 (as the main raw material) and a rare metallic oxide (as a solvent), and then calcined in a high heat of 1700 degC.
There are different types of alumina tiles that can be used as wear-resistant ceramics. These include alumina sheets, high aluminum linings (aluminum-based), 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, the hardness is extremely high. Rockwell hardness is HRA80-90. Second, its wear resistance, wear resistance that is higher than high-chromium cast-iron and manganese-steel, can extend the life of the equipment by more than tenfold. Third, it is light and has a density of 3.65g/cm. This can reduce the weight of the equipment. Fourth, the wear resistant alumina lining adheres firmly and is It is a good performer, and can be used for a very long time in temperatures up to 350 deg C.
Wear-resistant Alumina Ceramic Lining: It is made from non-metallic inorganic material. This means that it won't pollute the atmosphere. It is able to effectively prevent the breakage or peeling of surfaces caused by impacts. The wear-resistant ceramic lining has a high level of mechanical strength as well as good compatibility.
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 a paper background. 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 also be performed using a 45-degree spray angle, a 50-mm distance, and a pressure of 4 kg/cm3. 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 wear resistant ceramics last ten to twenty time longer than cast stones, steel plastic, steel and rubber.
