Jinan corn starch factory pre Hu Xin Rui

Pre burnt corn starch factory pre-burnt corn starch is a simple process, extensive use of modified starch, as long as the application of cold water into a burnt, eliminating the trouble of heating burnt. Widely used in building materials, medicine, 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. Hu of action can be divided into three stages: (1) irreversible absorption stage, the water enters the starch granules amorphous part, a slight expansion of the volume, then cooling and drying, the particles can be restored, birefringence unchanged (2 ) irreversible absorption phase, as the temperature rises, the water enters the starch microcrystalline gap irreversibly lot absorbent, birefringence gradually die burnt and even disappear, also known as crystal "dissolution", starch granules swell to 50 to 100 times its original volume ; (3) the final dissolution of starch granules, the starch molecules into the solution of all technical indicators: Item Index Appearance white powder, a water-soluble group burnt, burnt of toughness with good adhesion properties can swell into a deep translucent burnt fingers in cold water viscosity ≥ ? 300-2500mpa.s (2% aqueous solution) PH value of 7 (2% aqueous solution) fineness of 80 mesh ash ≤0.4 packaging, transport and storage Packaging: paper-plastic bag lined with plastic film bag, net weight 25kg. Transportation: available all kinds of transport vehicles, kept dry, and with the rain, waterproof, anti-moisture facility; not with toxic, hazardous, there are other abnormal odor mixed cargo; prohibited rain, water quality and other dirt contamination. Storage: Store in a dry, ventilated, cool place. Storage: One year. This information is provided by energy-saving materials Co., Ltd. Shandong Xin Rui
