The processing flow of China alumina ceramic tube

Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior performance, it has been widely used in modern society and meets the needs of daily use and special properties. Alumina ceramics and zirconia ceramics are new types of special industrial ceramics, they can be processed into ceramic rods, ceramic tubes, ceramic rings and other ceramic parts after a series of processes.

China alumina ceramic tube has extremely strong weather resistance, that is, it has strong adaptability to the external climate, is resistant to sunlight, acid rain corrosion, and has stable performance. It does not need to add paint or protective layer on its surface and cutting edges. Glaze is done.

China alumina ceramic tube is industrial Al2O3 is prepared from bauxite (Al2O3 ▪3H2O) and diaspore. For Al2O3 with high purity requirements, it is generally prepared by chemical methods. The molding methods mainly include extrusion, isostatic pressing, grouting, dry pressing, and high temperature calcination after injection molding, but they are different from ordinary ceramic tubes.

When the alumina ceramic tube is calcined, the composite ceramic material of zirconia, silicon oxide, silicon nitride and other powders will greatly increase the hardness and strength of the ceramic tube, and compared with the traditional ceramic tube, the water absorption of the alumina ceramic tube On the low side, the technology is more advanced, the cost is low, and the brittleness is relatively large.
