Analysis of Process Technology of Alumina Ceramics Processing
Alumina ceramics have very good wear resistance, which far exceeds that of stainless steel plates. Its strong strength determines its service life, which is ten times longer than that of ordinary porcelain; its The strength is comparable to diamond. Although it is a bit close, it has advantages over stainless steel plates and wear-resistant steel plates; although it has high hardness and strong wear resistance, it is very light and not heavy, and it is more convenient to operate.
Alumina ceramics are currently divided into high-purity type and general-purpose type. High-purity alumina ceramics are structural ceramics with Al2O3 content above 99.9%
Although the general powder superheated steam calcination method of alumina ceramics is more effective, it is because it is a trend in the traditional porcelain preparation and processing technology, and the green body calcination is carried out under the standard of dry hydrogen or vacuum pump, so it The long calcination temperature of the heat insulation and heat preservation time limits the increase of its transmittance.
Alumina ceramics generally have the advantages of insulating properties, low loss tangent value, high impact toughness, satisfactory organic chemical reliability, and rapid temperature resistance. They are used in many industrial sectors such as electronic devices, chemical plants, and textile equipment. used widely.
The characteristics of alumina ceramic sheet: firstly, its strength is high, its Rockwell hardness can reach HRA80-90; its wear resistance is very good, and its wear resistance can be higher than that of alloy steel and high chromium cast iron, which can increase the service life of machinery and equipment Ten times more.
