exchange thermal alumina Ceramic Bushing insulator
Reputation depends on quality, quality comes from Hard!
Alumina Ceramic:
Powder spray granulation is required for dry press molding, in which polyvinyl alcohol is introduced as a binder. A research institute in Shanghai developed a water-soluble paraffin as a binder for Al203 spray granulation, which has good fluidity under heating. The powder after spray granulation must have good fluidity, loose density, and a flow angle friction temperature of less than 30 °C. The particle gradation ratio is ideal and the like to obtain a larger bulk density.
Molding method
Alumina ceramic products are formed by various methods such as dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing. In recent years, molding techniques such as pressure filtration molding, direct solidification injection molding, gel injection molding, centrifugal grouting molding and solid free forming have been developed at home and abroad. Different product shapes, sizes, complex shapes and precision products require different molding methods.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
