wear resistance 99% aluminum oxide ceramic sleeve bush
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
In the traditional pouring method, the pre-drying of the green body is naturally dried in the grouting workshop. Within 16 hours after the workers are off work, the high temperature (33-40 ° C) and high humidity (40% -60 %) To make the body dry slowly. After pre-drying, the moisture content of the wet body is reduced from 15% to 17% to 8% to 10%. Care must be taken to prevent waste due to excessive drying or uneven drying. The modern grouting method generally uses hot air to directly force the billet to dry. The pre-drying shrinkage of the vitrified porcelain body is 4% and the pre-drying shrinkage of the clay body is 2%. The final process of grouting will ultimately determine the size of the green body. When the green body is repaired, the water content of the green body should be less, and the water used for brushing the green body should not be oily. After the green body is repaired, it should be stored at 28-35 ° C. Indoor, ready for glazing. 2 Points during the grouting operation (1) When grouting, wipe the mud on the model. Mix into the mud and avoid defects on the surface of the green body.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
