Starch ether Thicken the mortar, increase the sag resistance, sag resistance and rheology of the mortar

For example, in the construction of tile glue, putty, and plastering mortar, especially now that mechanical spraying requires high fluidity, for example, it is especially important in gypsum-based mortar (machine sprayed plaster requires high fluidity but will cause serious sagging phenomenon, starch Ether can make up for this defect).

Liquidity and sag resistance are often contradictory, and the increase in fluidity will bring about a decline in sag resistance. The mortar with rheological properties can well solve the contradiction that when an external force is applied, the viscosity decreases, which enhances the workability and pumpability, and when the external force is withdrawn, the viscosity increases and improves the sag resistance.

For the current trend of increasing tile area, adding starch ether can improve the slip resistance of tile adhesive.

2) Extend opening hours

For tile adhesives, it can meet the requirements of special tile adhesives with extended open time (Class E, extend from 20min to 30min to reach 0.5MPa).

a. Surface performance improvement

Starch ether can make the surface of gypsum-based and cement mortar smooth, easy to apply, and has a good decorative effect. It is of great significance for plaster-based mortars and thin-layer decorative mortars such as putty.

b. The mechanism of action of starch ether

When starch ether is dissolved in water, it will be evenly dispersed in the cement mortar system. Because starch ether molecules have a network structure and are negatively charged, they will adsorb positively charged cement particles, which can be used as a transition bridge to connect cement, thus giving The larger the yield value of the slurry can improve the anti-sagging or anti-slip effect.
