Hebei pre-burnt starch company

Ningjin Xin Rui energy-saving materials Co., manufacturer of high-quality, pre-burnt starch phone manufacturers pre-burnt starch CAS number, pre-burnt viscosity of starch, starch pre-burnt latest offer, the price of pre-burnt starch, pre-burnt the role of starch, starch pre-burnt execution GB, pre-burnt starch manufacturers latest offer, the amount of starch-based pre-burnt, usage and effect: Pre-processing of burnt starch is a simple, versatile modified starch, applied when Just tune into burnt with cold water, eliminating the trouble of heating burnt. Widely used in food, cosmetics, animal feed, oil drilling, metal casting, textile, paper and many other industries. The Principle of burnt starch: starch grains at an appropriate temperature (starch from various sources desired temperature, generally 60 ~ 80 ℃) swell in water, split to form a uniform action called burnt burnt-like solution of the role. Hu is the essence of the role of hydrogen bonds in starch molecules of starch grains ordered and unordered (amorphous and crystalline) state between the disconnected, dispersed in water become colloidal solution. Specifications: Item Index Appearance white powder, a water-soluble group burnt, burnt with good adhesion and toughness of performance can swell into a translucent deep burnt fingers viscosity ≥300-2500mpa.s (2% aqueous solution) PH value in cold water? ≥300-2500mpa.s (2% aqueous solution) fineness of 80 mesh ash ≤0.4 three application areas: high-viscosity pre-burnt starch-based products as cement, gypsum based products admixtures. And other buildings additives have good compatibility. And hydroxyl (qiang) methyl cellulose ethers used in conjunction, can play a thickening effect, promote internal structure, better crack resistance, improve workability, can significantly reduce the hydroxypropyl methyl cellulose added the amount.
