Introduction to the physical properties of alumina ceramic liner
As we all know, alumina ceramic liner is a kind of wear-resistant ceramic liner, and alumina ceramic liner is a kind of ceramic wear-resistant material that is widely used in industry.
To give a simple example: sand is a common item in everyone's daily life. The main component of sand is quartz, and its hardness is generally 7-8 on the Mohs level. The hardness of the alumina liner is 9 on the Mohs scale, so everyone should have a more vivid understanding of its hardness, that is, its hardness is very high. Everyone should only know that ceramics has one of its own shortcomings, which is that it is relatively brittle and will be broken when subjected to a relatively large impact. Therefore, if your working environment has a relatively large impact, the wear resistance of the ceramic liner will not be very good. Play it out.
The alumina ceramic liner is divided into 92 alumina wear-resistant ceramics and 95 alumina wear-resistant ceramics. The density of 92 alumina is 3.6 and the hardness is 9 grades. The density of the 95 alumina ceramic liner is about 3.65, and the hardness is also Mod 9 level. This kind of liner has excellent hardness and therefore exhibits excellent wear resistance. It is widely used in steel mills, thermal power plants, cement plants, docks, and mining industries. But it also has its shortcomings that it is relatively brittle, has poor toughness, and is prone to breakage when the impact force is relatively large. Another is that the thermal shock performance is not good, and it is prone to bursting in the case of rapid cold and rapid heat.
The alumina ceramic lining board above 99 is the best among the ceramic lining boards, and the unit price is extremely high, but its physical properties are also excellent, with high hardness and good toughness. It is especially suitable for parts with severe impact and wear.
