Characteristics of injection-molded alumina wear-resistant ceramics

The content of aluminum oxide (A1203) in injection molded alumina wear-resistant ceramic products is more than 96%, which includes ingredients, preparation of binders, mixed binders and alumina, mechanical kneading, mechanical granulation, injection molding, and degumming, Firing and other steps, the surface of the porcelain is more smooth and the porcelain hardness is greater. During the high-speed spinning process, there will be no burrs on the surface of the porcelain, which improves the spinning quality.

The surface finish of the injection-molded alumina wear-resistant ceramic products is high. After polishing, the roughness is not greater than 0.2, and the surface is not easy to produce burrs, which significantly improves the quality of chemical fibers. The product has a large hardness, and its hardness value is HRA88, which can meet high-speed spinning. Requirements: The injection molding process pressure is high, the blank density is high, and the size is accurate, which ensures that the product density is greater than 3.9g/cm3; the total shrinkage rate of the injection molding process is 11, and the deformation is small, which ensures that the product size is more accurate.
