Pregelatinized starch 1. Product introduction contact person Wu Haili
Pregelatinized starch is a kind of natural starch as raw material, which has been modified through modification. It has many important properties, including solution thickening, good water solubility, suspension or stability with glue, protective colloid effect, film forming, water retention, adhesive properties, non-toxic, odorless, biocompatibility, thixotropy wait. In the construction industry (insulation mortar, putty powder, ceramic tile bonding, building mortar, etc.), the construction performance can be improved, while the production cost can be reduced by about ~.
, good rapid thickening ability and certain water retention.
, the dosage is small, very low addition amount can achieve high effect.
, Improve the material's ability to resist sliding.
, improve the operating performance of the material and make the operation smoother.
, extend the opening hours of materials.

3. Application areas
High viscosity pregelatinized starch is widely used in feed, foundry, oil drilling, corrugated cartons , building materials coatings and other industries. It has good compatibility with other building admixtures. Used in conjunction with hydroxypropyl methylcellulose ether, it can thicken, promote the internal structure, have better crack resistance, improve workability, and can significantly reduce the amount of hydroxypropyl methylcellulose added.
High viscosity pregelatinized starch has a wide range of uses in the building materials industry. It is used in large amounts and can be used as a retardant, water retaining agent, thickener and adhesive. In ordinary dry mixed mortar, exterior wall insulation mortar, self-leveling mortar, dry powder plastering adhesive, ceramic tile bonding dry powder mortar, high-performance building putty, crack-resistant interior and exterior wall putty, waterproof dry mixed mortar, gypsum plaster, scraping filler , thin-layer joints and other materials, and plays an important role in the water retention, solidity, retarding and constructability of the stucco system.

Add this product to the auxiliary materials and auxiliaries in proportion, and dry mix evenly. Add cold water to mix during construction before use. The above parameters are for reference only. For safety reasons, the specific conditions of local auxiliary materials should be used during construction, and strict feasibility tests must be done first to achieve the best use results.
If after mixing, it is found that it cannot be scraped during construction, the amount of pregelatinized starch should be reduced. On the contrary, the addition amount should be increased. If after mixing, the mixture is too tight during construction, it is because the mixture is not evenly mixed.
5. Packaging, transportation and storage
Packaging: Plastic woven bags lined with plastic film bags, net weight per bag.
Transportation can be carried by various means of transport, kept dry, and equipped with rainproof, waterproof, and moisture-proof facilities. Do not mix with other goods that are toxic, harmful, or have abnormal odors. Contamination by rain, water, and other contaminants is strictly prohibited. .
Storage should be stored in a dry, ventilated, and cool place. Storage period is one year.
