The alumina ceramic tube has strong weather resistance, that is, it has strong adaptability to the outside climate, is resistant to sunlight, acid rain and corrosion, and has stable performance.

The alumina ceramic tube has strong weather resistance, that is, it has strong adaptability to the outside climate, is resistant to sunlight, acid rain and corrosion, and has stable performance. It does not need to add paint or protective layer on its surface and cutting edge. It is directly processed after finishing. Glazed will do.

Alumina ceramic tube is industrial Al2O3 which is made of 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 calcining after injection, but they are different from ordinary ceramic tubes.

Adding zirconia, silicon oxide, silicon nitride and other powder materials to the composite ceramic material of the alumina ceramic tube during calcination 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.
