What is Starch ether
Starch is one of the most prolific natural polymers and is composed of amylose and amylopectin. And starch ether is made from starch by chemically modified.
Because potato starch is one of the high purity starch, so it’s the best choice for building, and the molecular weight of starch and the degree of etherification determine the consistency and workability of the starch applied to the mortar product, besides, the fineness of the starch determines its dissolution rate in the water.
2. What’s the role of starch ether in dry mortar
Starch ether is widely used in the dry mortar industry because it’s cost-effective compared to other raw materials. And it provides much good performance.
1. Adjusting the performance of mortar in the state of fresh mixing.
2. It could prevent the sag during mechanical construction and manual plastering,
3. Significantly improve the construction performance of the mortar and increase the output rate.
4. As an effective additive to prevent tile slippage.
5. It could prevent sedimentation, segregation when it’s applied in self-leveling mortar and grouting material.
3. How to make Starch ether
Usually, we use Carboxymethylation(CM), and hydroxyalkyl (HP) and cross-linking (CL) methods to modificate starch, the amylase could get quick swelling, smooth, resistance to alkali, temperature stability, shear stabilit through different chemical modifications.
4. The effect of particle size
The solubility of starch varies with particle size. The smaller the particle size is, the faster the dissolution rate of starch is, so is in the thickening effect. Throufh physical modification, the applicability of starch is more extensive.
