Starch ether
Used in conjunction with methyl cellulose ether, it shows a good synergistic effect between the two. Adding an appropriate amount of starch ether to methyl cellulose ether can significantly improve the sag resistance and slip resistance of the mortar, and has a high yield value.
In the mortar containing methyl cellulose ether, adding an appropriate amount of starch ether can significantly increase the consistency of the mortar and improve the fluidity, making the construction smoother and the scraping smoother.
In the mortar containing methyl cellulose ether, adding an appropriate amount of starch ether can increase the water retention of the mortar and prolong the open time.
Starch ether is a chemically modified starch ether soluble in water, compatible with other additives in dry powder mortar, widely used in tile adhesives, repair mortar, plaster plaster, interior and exterior wall putty, gypsum-based caulking and filling Materials, interface agents, masonry mortar.
Starch ether is mainly used in construction mortar, which can affect the consistency of mortar based on gypsum, cement and lime, and change the construction and sag resistance of mortar. Starch ethers are usually used in conjunction with non-modified and modified cellulose ethers. It is suitable for both neutral and alkaline systems, and is compatible with most additives in gypsum and cement products (such as surfactants, MC, starch and water-soluble polymers such as polyvinyl acetate).
The characteristics of starch ether mainly lie in:
⑴Improve sag resistance;
⑵ Improve construction;
⑶ Improve the water retention rate of mortar
