The Role of Starch Ether in the Mortar
Please visit our website for more information on this topic.
- Thicken the mortar, increase the sag resistance, sag resistance, and rheology of the mortar
For example, in the construction of tile adhesive, putty, and plastering mortar, especially now that mechanical spraying requires high fluidity, for example, it is imperative in a gypsum-based mortar (machine sprayed gypsum needs high fluidity but will cause severe sagging. 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 will decrease, and the workability and pumpability will be enhanced. When the external force is withdrawn, the viscosity will increase and improve the sag resistance.
For the current trend of increasing tile area, adding starch ether can improve the tile adhesive slip resistance.
- Extend opentime
It can meet the requirements of special tile adhesives for tile adhesives with extended opening hours (Class E, extend from 20min to 30min to reach 0.5MPa).
- Improved surface properties
Starch ether can make the surface of gypsum-based and cement mortar smooth, easy to apply, and has an excellent decorative effect. It is significant for plastering mortars and thin-layer decorative mortars such as putty.
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. As a transition bridge, the cement can be connected to give the slurry a more considerable yield value, improving the anti-sagging or anti-slip effect.
Hydroxypropyl Starch Ether - HPMC
Hydroxypropyl Starch Ether
Hydroxypropyl starch ether can give unique properties to cement and gypsum based products. It has a similar chemical structure to Hydroxypropyl Methyl Cellulose (HPMC), and not only has functions similar to Hydroxypropyl Methyl Cellulose (HPMC), but also has good compatibility with other building additives. Hydroxypropyl starch ether and hydroxypropyl methyl cellulose (HPMC) can be used together to provide better thickening effect, better crack resistance and improved ease of use. And by adding starch ether, the cost of mortar formulation can be significantly reduced.
Properties of hydroxypropyl starch ether
● Hydroxypropyl starch ether has anti-sagging properties, which can improve anti-sagging performance and optimize construction performance;
● Hydroxypropyl starch ether can effectively prevent the phenomenon of thick layer overhanging of mortar, which is good for improving the undesirable phenomena of tile slippage and thick layer overhanging;
● Adding an appropriate amount of hydroxypropyl starch ether to the mortar can delay its opening time. As the temperature rises, the water retention of starch ether remains stable. Therefore, this product can not only improve the water retention performance of mortar, but also make up for the phenomenon that the water retention capacity of ordinary water retention agent retains rapidly with the rise of temperature;
● Hydroxypropyl starch ether has a fast thickening effect on mortar, which can improve the rheology of spraying mortar and plastering mortar;
● Hydroxypropyl starch ether can effectively prevent mortar delamination/separation and can be well used in self-leveling mortar.
Application
● Tile adhesive-C2
● Wall mud (interior and exterior)
● Block joint mortar
● ACC bonding mortar
● Manufacture of glues and adhesives
