1. Technology

Hydroxypropyl starch ether (HPS), also known as modified starch ether, is a white fine powder obtained from natural plant as raw material, modified, highly etherized, and then spray dried. It does not contain plasticizers. It is completely different from ordinary starch or modified starch.

Project index

Appearance: white or light yellow powder

Solubility is soluble in cold water, aqueous solution is transparent and colorless.

Water content (%) is less than 14.

PH (1%, 25 C) 5-11.5

Viscosity (5% aqueous solution, 20 mPa.s, >100)

Hydroxypropyl content (%) 20-40

Two, application area:

It can be used as admixture for cement based products, gypsum based products and calcium lime products. It has good compatibility with other building admixtures. When used in conjunction with hydroxypropyl methylcellulose ether (HPMC), it can play a thickening role, promote the internal structure, and have better cracking resistance and improve workability. The addition of hydroxypropyl starch ether can significantly reduce the amount of HPMC added.

In addition, HPS can also be used as adhesive, suspension agent and thickener in papermaking, textile, oil drilling, daily chemical industries.

Three, application characteristics:

1, good rapid thickening capacity; medium viscosity, has a certain water holding capacity;

2, small dosage, very low dosage can achieve very high results.

3, improve the anti slide ability of materials;

4, improve the operation performance of the material and make the operation more slippery.

5, extend the opening time of materials;

It is recommended for use in the following materials:

1. All kinds of putty powder for cement, gypsum, lime calcium base and exterior wall.

2, all kinds of (ceramic tile, stone) binder;

3, all kinds of decorative mortar and all kinds of plastering mortar.

Four, recommended dosage:

0.05%-0.1% can also reduce methyl cellulose ether by about 0.1%.

Five, packaging:

25 kilos / bags
