Common alumina ceramic pieces in many industrial production occasions will be used, which shows that alumina ceramic pieces compared with other materials have a lot of superior performance, will be very popular in the industry. The forming methods of alumina ceramic parts include dry pressing, grouting, extrusion, cold isostatic pressing, injection, flow casting, hot pressing and hot isostatic pressing.
The production process of alumina ceramic parts is generally divided into three main steps, in order to ensure the quality of each link to do a good job, the first is the preparation of ceramic powder as raw materials. For general purpose ceramics, there is a ready - made spray - dried granulation powder available on the market.
If you need to control the formulation of the material, you need to buy a ball mill and ball and spray dryer. With the raw material can begin pressing molding, for less than 2 mm sheet products, you can consider the use of gelatinization method; And for more than 2 mm ceramic pieces can be considered to use the press to press the method of molding.
At present, alumina ceramic parts can be used for temperature measuring instrument thermocouple thermometer protection tube, insulation tube; At the same time, it can also be used in industrial resistance furnace, experimental furnace, heat treatment furnace tube. In addition, steel and iron chemical analysis of carbon tubes and sulfur tube, as well as other high temperature, acid and alkali corrosion resistance insulation instrument components should be used ceramic porcelain as the basic parts.
Alumina ceramic factory produces alumina ceramic parts using its strong mechanical strength, thermal shock resistance; Good thermal conductivity, insulation, and high softening temperature advantage, in many industries have been used, welcome to buy.
