| Main characteristics of starch ether: (1) starch ether is usually used in combination with methyl cellulose ether, which shows a good synergistic effect between the two. Adding an appropriate amount of starch ether into methyl cellulose ether can significantly improve the anti-sag and anti-slip properties of mortar, with a high yield value. (2) in the mortar containing methyl cellulose ether, adding an appropriate amount of starch ether can significantly increase the consistency of the mortar, improve the flow performance, and make the construction smoother and scraping smoother. (3) in the mortar containing methyl cellulose ether, adding an appropriate amount of starch ether can increase the water retention of the mortar and extend the opening time. (4) starch ether is a chemical modified starch ether soluble in water, compatible with other additives in dry mortar, widely used in ceramic tile adhesive, repair mortar, plaster, internal and external wall putty, gypsum base caulking and filling materials, interface agent, masonry mortar. The characteristics of starch ether mainly lie in: 1. (2) improve the construction; We can improve the rate of mortar Application of starch ether: Starch ether is mainly used in building mortar, which can affect the consistency of mortar based on gypsum, cement and lime, and change the construction property and resistance to sag of mortar. Starch ether is usually used in combination with non-modified and modified cellulose ether. It is suitable for both neutral and alkaline systems and is compatible with most additives found in gypsum and cement products (such as surfactants, MC, starch and water-soluble polymers such as polyvinyl acetate). Recommended usage of starch ether :0.03%~0.05%. |
