Kingcera Parts and Components Made of Alumina Ceramic
Part and components made of alumina ceramic
Kingcera offer optimized wear protection for plant componets and pipe systems.
Why wear protection?--- reduce costs and avoid downtime.
Product structure:
Structure ceramic is a large group of new ceramic material of which the mechanical, heat and chemical properties are fully utilized. It can be used in a lot of rigorous working conditions, which makes it the key for the realization of many emerging technologies. Compared with metal material, the most outstanding advantage is its superior mechanical properties at high temperature, chemical resistance, resistane of oxidatioin at high temperature, wear resistance and low density (about 1/3 that of metal), therefore, it is gradually being used instead of expensive supper alloy steel in the cases that metal material cannot be competent, such as cylinder cover of engine, bush, paking ring and cut tools for ceramic.
Clear advantages:
--- long lifetime
--- maintenance free operation
--- no operation interuption
--- no production losses
--- no contaminaiton of conveyed mataterial due to abrasion, mixture or oxidation
--- physiologically harmless, suiable for food products
--- smooth surface to achieve good flowability and to aviod plugs
--- reduced pressure losses and lower energy cost
