The common thermal conductive ceramic gasket is alumina ceramic material. Because the thermal conductivity of alumina material is very high, it can be used as a thermal conductive and heat dissipation gasket. The following Pintejin ceramic zirconia machining factory will tell you about the thermal conductivity of alumina thermal conductive ceramic gasket. Where is the advantage.
Alumina thermal conductive ceramic gasket: high alumina content, relatively dense structure and special properties, so it is called special ceramics.
The alumina thermal conductive ceramic gasket material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions are filled in two-thirds of the octahedral gap, which is the same stable α-Al2O3 structure as natural corundum, so the ceramic has high Melting point, high hardness and excellent wear resistance.
The hardness of alumina thermal conductive ceramic gasket is ≥HRA85, second only to the hardness of diamond, and the surface is smooth and the friction coefficient is small, and the wear resistance is very ideal, especially in high temperature oxidizing medium or corrosive medium, the material of ceramic patch is better than other The performance of metal materials is much better.
1. High hardness
As determined by the Shanghai Institute of Silicate, Chinese Academy of Sciences, its Rockwell hardness is HRA80-90, the hardness is second only to diamond, and the wear-resistant ceramic plate far exceeds the wear-resistant performance of wear-resistant steel and stainless steel.
2. Very good wear resistance
As determined by the Institute of Powder Metallurgy of Central South University of Technology, its wear resistance is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. According to our customer follow-up survey for more than ten years, under the same working conditions, the service life of the equipment can be extended by at least ten times.
3. Light weight
Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the equipment load.
4. Wide range of applications
Take coal transportation, material transportation system, pulverizing system, ash discharge, dust removal system and other machinery and equipment with large wear and tear in thermal power, steel, smelting, machinery, coal, mining, chemical, cement, port and other enterprises. Different needs choose different types of products.
