Physical properties of alumina ceramic liner
Nowadays, customers are concerned about the physical properties of the alumina ceramic lining, that is, the wear resistance. In fact, the wear resistance of the alumina ceramic lining is determined by many factors, so now the editor of Junjie Ceramics Let's take a look at the wear resistance of alumina ceramic liner:
As we all know, alumina ceramic lining is a type of wear-resistant ceramic lining, and alumina ceramic lining 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 our daily life. The main component of sand is quartz, and its hardness is generally 7-8 on the Mohs scale. The hardness of the alumina liner is Mohs 9, so everyone should have a relatively vivid understanding of its hardness, that is, its hardness is very high. Everyone should only know that ceramics have their own shortcomings, that is, they are relatively brittle and will be broken when subjected to a relatively large impact. Therefore, if the impact force of your working environment is relatively large, the wear resistance of the ceramic lining plate will not be able to play well. come out.
The alumina ceramic lining plate is further divided into 92 alumina wear-resistant ceramics and 95 alumina wear-resistant ceramics, of which the density of 92 alumina is 3.6 and the hardness is Morse 9. The density of the 95 alumina ceramic liner is about 3.65, and the hardness is also Morse 9. This liner has excellent wear resistance because of its excellent hardness, and is widely used in steel mills, thermal power plants, cement plants, docks, and mining industries. However, it also has its shortcomings: it is relatively brittle and has poor toughness. In the case of a relatively large impact force, it is prone to breakage. In addition, the thermal shock performance is not good, and it is easy to burst under the condition of rapid cooling and rapid heating.
