Chemical organic additives
The so-called additives refers to the increase in product quality and the effect of adding a small amount of ingredients or trace reagents in the preparation of ceramic raw materials in a variety of organic additives, can be used as dispersants, plasticizers, plasticizers, surface modifiers Used in the process of each process.For the daily use of ceramics, it can shorten the process, improve product quality and other excellent role; special ceramic materials, mostly belonging to the barren powder, plasticizers, surface modifier application appears to be It is more necessary because of the successful application of a variety of organic additives for the development of new inorganic ceramic materials opened up a broad prospect.
Porcelain clay surface damage can occur Si ─ O bond, Al ─ O bond break, resulting in positive and negative charge Si +4, Al +3, O-2, they can strongly act on the dispersion medium. Oleic acid and linen Acid active group - COOH (hydroxyl), carbon - carbon double bond> C = C
Grinding aids: In the process of grinding clay, the use of a variety of grinding aids, their addition is generally a few thousandths, can play a strengthening porcelain clay smashing effect.
