HPMC Hydroxypropyl Methyl Cellulose products for construction are widely used to improve the performance of cementitious building materials such as cement and gypsum. In cement-based mortar, it can improve water retention, prolong correction time and opening time, and reduce sagging phenomenon.
1. Improve construction efficiency
The application of
Hydroxypropyl Methyl Cellulose HPMC can improve the workability of mortar construction.
2. Water retention property
Hydroxypropyl Methyl Cellulose for construction is used to prevent moisture from seeping into the wall. An appropriate amount of water stays in the mortar, allowing the cement to hydrate for a longer period of time. The water retention is proportional to the viscosity of the cellulose ether solution in the mortar, and the higher the viscosity, the better the water retention. Once the water molecules increase, the water retention decreases. Because for the same amount of building specific
Hydroxypropyl Methyl Cellulose solution, an increase in water content means a decrease in viscosity. Improving water retention can lead to an extension of the curing time of the mortar being constructed.
3. Lubrication ability
All air entraining agents have a wetting effect as they reduce surface tension and help disperse fine powder in mortar when mixed with water.
4. Bubble content
High bubble content leads to better mortar yield and workability, reducing cracking formation. It also reduces the strength value and causes the phenomenon of "liquefaction". The bubble content usually depends on the stirring time.
5. Anti current hanging
Good anti sagging mortar means that there is no risk of sagging or downward flow during thick layer construction. The anti sagging performance can be improved by building specific
Hydroxypropyl Methyl Cellulose. Especially the newly developed building specific
Hydroxypropyl Methyl Cellulose can provide better anti sagging properties for mortar
