The wear-resistant ceramic piece is a special corundum ceramic made from Al2O3 as the main raw material and rare metal oxide as the flux, which is roasted at 1,700 degrees high temperature. Wear-resistant ceramic pieces have a variety of names, Mosaic porcelain pieces, alumina ceramic pieces, ceramic lining and so on. Generally, the aluminum content of 92-99% is collectively referred to as high aluminum ceramic sheets. The hardness of wear-resistant ceramics is as high as 80HRA, second only to diamond, and the wear resistance exceeds that of wear-resistant steel, which is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. It can be widely used as anti-wear material for industrial equipment.
Wear-resistant ceramic pieces are mostly used in power plants or cement plants and other industries, but in some equipment, the flow rate is fast, or the temperature is too high, and the material scouring force is strong, it is easy to cause the wear-resistant ceramic pieces to fall off. Once the ceramic falls off, the equipment is not protected, and it is easy to wear and tear, affecting the safe production of the system. So how do you solve this problem?
For the phenomenon of ceramic piece falling off, it is necessary to design a suitable plan according to the working condition. If the ceramic falls off due to high temperature, it is necessary to use high-temperature ceramic glue or high-temperature cement, so that the ceramic will not fall off.
If the material impact force is too large to cause the ceramic sheet to fall off, it means that the ordinary ceramic sheet has been unable to resist this too large impact, and it is necessary to use an anti-impact wear-resistant liner, such as a ceramic composite liner, or a welded anti-strip liner.Ceramic composite liner is composed of rubber, ceramic and steel plate, rubber can buffer the impact of the material, coupled with the high wear resistance of ceramic, can be used for the impact of large conditions. The welded ceramic liner has a conical hole in the middle, in addition to the inorganic adhesive adhesive, but also need to use bolts through the conical hole and the equipment welded together, forming a double fixing effect, to ensure that the ceramic liner is not easy to fall off.
It is recommended to select suitable wear-resistant ceramics in different equipment conditions. Chemshun has many years of construction experience, is a professional manufacturer of wear-resistant ceramics, can provide suitable solutions according to customers’ equipment.
