Hydroxypropyl starch ether
I. Technical requirements:
“宸邦” 羟丙基淀粉醚 （ HPS) 是以天然植物为原料，经过改性、高度醚化反应、然后喷雾干燥而得到的白色精细粉末，不含增塑剂。 1. "Shenbang" hydroxypropyl starch ether ( HPS) is a white fine powder obtained from natural plants as raw materials, modified, highly etherified, and then spray-dried, without plasticizers. It is completely different from ordinary starch or modified starch.

应用领域： Application fields:
Can be used as admixtures for cement-based products, gypsum-based products and grey calcium products. Has good compatibility with other building additives. 配合使用，能起到增稠作用，促进内部结构，具有更好的抗裂性和提高和易性。 Used in combination with hydroxypropyl methyl cellulose ether ( HPMC) , it can play a thickening role, promote internal structure, have better crack resistance and improve ease. HPMC 添加量。 The addition of modified starch ether can significantly reduce the amount of HPMC added.
、 应用 特性 ： Application characteristics :
1. Good fast thickening ability; medium viscosity, some water retention;
2. The dosage is small, and the extremely low addition amount can achieve a high effect;
3. Improve the anti-sliding ability of materials;
4. Improve the operation performance of the material and make the operation smoother.
5. Extend the opening time of materials;
建议应用于以下材料中 ： 4. It is recommended to be applied to the following materials :
( 水泥、石膏、灰钙基 ) 内、外墙腻子粉； 1. Various types ( cement, gypsum, gray calcium based ) putty powder for internal and external walls
( 瓷砖、石材 ) 粘结剂； 2. Various types of ( tile, stone ) adhesives;
3. Various decorative mortars and various plastering mortars.
0.05%-0.1% 同时可以降低甲基纤维素醚 0.1% 左右。 4. Recommended dosage: 0.05% -0.1% can reduce methyl cellulose ether by about 0.1% .
： 5. Packaging :
