Uisciú ceallalóis Methyl Hidroxypropyl de ghrád tógála go cementmortar:

1、The viscosity, dosage, ambient temperature and molecular structure of Ceallalóis Meitile Hiodrocsapróipilín Tógála have a great influence on its water retention performance. Under the same conditions, the higher the viscosity of Construction grade Hydroxypropyl Methyl Cellulose, the better the water retention; the higher the content, the better the water retention, and the higher the ambient temperature, the water retention of cellulose ether usually decreases, but some modified Construction grade Hydroxypropyl Methyl Cellulose also has better water retention under high temperature conditions; Ceallalóis Meitile Hiodrocsapróipilín Tógála with a lower degree of substitution has better water retention.

2、The hydroxyl group on the Construction grade Hydroxypropyl Methyl Cellulose molecule and the oxygen atom on the ether bond will associate with the water molecule to form a hydrogen bond, turning the free water into bound water, thus playing a good water retention effect; the water molecule and the hydroxypropyl methyl group The mutual diffusion between cellulose molecular chains allows water molecules to enter the hydroxypropyl methyl cellulose macromolecular chain, and is subject to a strong binding force, thereby forming free water, entangles the water, and improves the water retention of cement slurry;


Therefore, in the production of building materials, especially dry mortar, Ceallalóis Meitile Hiodrocsapróipilín Tógála plays an irreplaceable role and is an indispensable and important part.
