Abstract

Provided is a porcelain sintering defoamer embedded in a furnace. The defoamer is prepared from 10-50 parts of metal corrosion inhibitor, 100-150 parts of deionized water, 1-5 parts of diethylene glycol, 2-5 parts of dispersing agent, 10-20 parts of polyethylene glycol, 40-50 parts of tap water, 10-15 parts of sweet potato stems and leaves, 10-50 parts of deionized water, 20-25 parts of forage, 10-13 parts of animal giblets, 6-9 parts of modified organosilicone defoamer emulsion, 1-3 parts of block polyether, 2-10 parts of quaternary ammonium salt, 1-5 parts of hydrophobic silicon dioxide, 3-5parts of fluorine-containing polysiloxane and 1-2 parts of epoxypropane. In the porcelain sintering defoamer, through the metal corrosion inhibitor and the dispersing agent, liquid with the condensation effect is prepared, the liquid is dispersed on the surface of an embryo body to cool the embryo body after being evaporated with the high temperature, the temperature is reduced, and bubbles on the surface is reduced.

Description

Technical field: [0001] The invention relates to the field of ceramics, in particular to a porcelain sintering defoamer built in a kiln. Background technique: [0002] Ceramics is the general term for pottery and porcelain. The Chinese invented pottery as early as about 8000-2000 BC (Neolithic Age). Ceramic materials are mostly oxides, nitrides, borides and carbides. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have higher hardness, but poor plasticity. In addition to the use of tableware and decoration, it also plays an important role in the development of science and technology. The raw material of ceramics is obtained by quenching the earth's original large resource clay. The nature of clay is tough, it can be molded when exposed to water at room temperature, it can be carved when it is slightly dry, and it can be ground when it is completely dry; it can be made into pottery and can hold water when it is fired to 700 degre...
