Description
Technical field：
The present invention relates to ceramic field, and in particular to a kind of porcelain sintering defoamer being built in kiln.
Background technology：
Ceramics are the general names of pottery and porcelain.Chinese just send out early in about B.C. 8000-2000 (Neolithic Age)
Understand pottery.Ceramic material is oxide, nitride, boride and carbide etc. mostly.Common ceramic material has clay, oxygen
Change aluminium, kaolin etc..The general hardness of ceramic material is higher, but plasticity is poor.Except feeder, decoration use on, in section
Learn, also played an important role in the development of technology.Ceramic raw material is that the original ample resources clay of the earth forms by quenching to take.And
The property tool toughness of clay, normal temperature chance water is plastic, and micro- do can carve, absolutely dry to grind；Water can be filled into pottery by burning to 700 degree；Burn extremely
1230 degree of then porcelain, can not absorb water and corrosion-and high-temp-resistant completely.The elasticity of its usage, still have in culture today science and technology various
The application of intention.
Firing refers to by high-temperature process, makes base substrate that a series of physical chemical change, mineral composition expected from formation occur
And microstructure, so as to reach fixed profile and obtain required by effect process.It is the 3rd important procedure of ceramic process.
Sintering is that powdered compact is heated to be incubated below the melting temperature less than its basic constituent element, is then cooled to the heat of room temperature
Handling process.
