제품 설명

99% 99.5% alumina ceramic sharp conical fillet rod

Reputation depends on quality, quality comes from Hard!

Alumina Ceramic:

The alumina powder entering the plant is prepared into a powder material according to different product requirements and different molding processes. The particle size of the powder is less than 1 μm. If the purity of the alumina is 99.99%, the high-purity alumina ceramic product needs to be ultra-finely pulverized and the particle size distribution is uniform. When extrusion molding or injection molding is used, a binder and a plasticizer are introduced into the powder. Generally, a thermoplastic plastic or resin organic binder having a weight ratio of 10-30% should be at a temperature of 150-200 with the alumina powder. Mix evenly underneath to facilitate the molding operation. The powder raw material formed by the hot pressing process does not need to be added with a binder. If semi-automatic or fully automatic dry pressing is used, there is a special process requirement for the powder. It is necessary to spray the granulation method to treat the powder to make it spherical, so as to improve the fluidity of the powder and facilitate the automatic filling of the molding. wall. In addition, in order to reduce the friction between the powder and the mold wall, it is necessary to add 1 to 2% of a lubricant such as stearic acid and a binder PVA.


High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
