The designs raw material of pottery and porcelain main component that makings of oar of 1 high polymer compound pottery and porcelain reduces water grinding aid is mica of quartz, feldspathic, kaolin, thin silk to wait, the clay mineral grain such as kaolin belongs to micelle category, have the general character of colloid, and the barren sex raw material such as quartz does not belong to micelle category. In the oar makings that did not add chemical additive, free water adsorption is in argillaceous grain surface, need to add many water dilute to make oar makings has liquidity, such ability that grind a ball make through the action such as significant impact, extruding mineral grain mill. Adscititious and chemical additive still can rise to reduce the effect that freedom of mineral grain surface can disperse with hardness and stability. Because the slop of this design reduces water grinding aid,should have make mineral grain admirably free water desorption, reduce freedom of mineral grain surface to be able to reach hardness and the function that make mineral grain dispersive. Water glass, sodium carbonate is used commonly in production of domestic pottery and porcelain, 3 get together phosphoric acid natrium, humic the tradition such as acerbity natrium decreases water agent, its basically can rise to make mineral grain free the action of water desorption, add a capacity bigger, but action result is poor, do not live price on the low side. Foreign advanced ceramics manufactures the does not use onefold constituent basically chemical additive in craft, use commonly get together carboxylic acid kind the auxiliary of makings of oar of compound pottery and porcelain that high polymer gives priority to. Auxiliary of makings of oar of this kind of compound pottery and porcelain is had afore-mentioned a variety of functions, but its price is high, at present home basically still is used in the production of the high-grade pottery and porcelain such as special type pottery and porcelain. To develop the auxiliary of makings of oar of pottery and porcelain with low muti_function cost, this research is opposite above all of natural high polymer humic acid undertook low cost modified, more close water base the group introduces humic in acerbity element, raise its to replace the capacity of the free water of adsorption of mineral grain surface and dispersive and mineral grain considerably. Designed density of negative electric charge and space next block gets together greatly carboxylic acid kind high polymer, choose a variety of gender price to compare tall monomer, improved synthetic technology, make get together carboxylic acid kind the manufacturing cost of high polymer reduces half above. Compared inorganic salt to decrease water agent to expect in oar of pottery and porcelain the sexual price in production is compared finally, the inorganic salt that chooses efficient low cost and modified are humic acerbity, get together carboxylic acid kind high polymer undertakes answer match, reduced slop of high polymer compound pottery and porcelain to reduce the cost of water grinding aid further. 3.
