HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
The performance of HPMC in dry mortar:
A. Excellent water retention can effectively prevent the morta arfrom losing water so quickly as to lose its operability, and avoid rapid surface drying and cracking, and make the mortar have a lon ger opening time and adjustment time;
B. The thickening effect ofHPMC can control the mortar to ac hieve the best consistency, improve the cohesion of the mortar, achieve anti-sagging effect, improve operability, and greatly improve construction efficiency;
C.It can improve the bonding strength of the mortar, and i t can ensure sufficient moisture and time to fully hydrate the cemen thereby ensuring that the mortar has better bonding perforn hance and strength even in a high temperature environment.
