Gelatinized starch is a natural starch as raw material, through improvements made. It has many important properties, including: a solution thickening, good solubility in water, suspended or glue stability, protective colloid effects, film, water retention, adhesion properties, non-toxic, tasteless, biocompatibility, touch degeneration. In the construction industry (insulation mortar, putty powder, tile adhesive, building mortar, etc.) can improve the workability, while production costs are reduced by about 10 to 20%. 1, a good fast thickening ability, a certain retention. 2, the amount of small, low additive amount that can achieve high results. 3, to improve the ability of anti-falling material. 4, to improve the operating performance of the material, make the operation more smooth. 5, to extend the opening hours of material. Second, the technical indicators: Item Index Appearance white powder, a water-soluble paste group, with good toughness pasting sticky inflation performance can be deep into a translucent paste viscosity ≥300-2500mpa.s (2% aqueous solution) in cold water PH value 7 (2% aqueous solution) fineness of 80 ash ≤0.4 three application areas: high-viscosity pre-gelatinized starch-based products as cement, gypsum based products admixtures. And other buildings additives have good compatibility. And hydroxypropyl methyl cellulose ethers used in conjunction, can play a thickening effect, promote internal structure, better crack resistance, improve workability, can significantly reduce the amount of hydroxypropyl methylcellulose. High viscosity pre-gelatinized starch in the building materials industry has its wide range of uses, the amount is large, it can be used as a retarder, insurance agent, thickener and binder. In ordinary dry mix mortar, exterior insulation mortar, self-leveling mortar, dry adhesive plaster, tile adhesive dry mortar, high-performance architecture putty within the external walls cracking putty, waterproof dry mortar, plaster, scratch filler agent , thin seams and other materials play an important role in water retention of mortar systems, sturdiness, and construction of retarding an important role. Fourth, the reference formulation interior wall putty powder formulations 1 Flying powder: 1000 kg 2 pre-gelatinized starch: 5 kg 3 CMC: 10-15 kg 1, the goods, to add materials and additives, dry mix evenly, construction When adding cold water mixing can be used. Only for reference, the construction materials for safety should be based on local circumstances, must first rigorous feasibility test, in order to achieve the best results. 2, if reconcile after a good, if found scraping open in the construction, should reduce the amount of pre-gelatinized starch. On the other hand, should increase the amount of CMC. If reconcile well after construction hold together tightly, because of uneven mixing. Fifth, 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. Technical Advisory pellet project vice president Xing Xiangjia 13730220127
