Retención de agua HPMC
Retención de agua HPMC is a non-ionic cellulose ether. In cement mortar and gypsum-based slurry, it mainly plays a role of water retention and thickening, which can effectively improve the adhesion and sag resistance of the slurry. It is an indispensable additive in mortar and paste. Retención de agua HPMC produced by Milestone Industrial Co. Ltd. has high purity and good quality. It has excellent water retention and thickening properties when used in mortar and gypsum. It is the first choice for cellulose ethers in your construction industry.

¿La capacidad de retención de agua y la cantidad de retención de agua de HPMC se ven afectadas por la temporada?
1) Since air temperature, wind pressure and other factors will affect the volatilization rate of water in cement mortar and gypsum-based products, there are some differences in the water retention effect of the same amount of Retención de agua HPMC in different seasons.
2) En diferentes estaciones, el efecto de retención de agua de la lechada se puede ajustar aumentando o disminuyendo la cantidad de retención de agua de HPMC durante una construcción específica. Promueva el mortero y el yeso para mostrar una retención de agua diferente.

El desempeño en operaciones específicas es el siguiente:
If you want to achieve the water retention effect during the high temperature summer construction, you need to add high-quality HPMC water retention in sufficient quantities according to the formula, so that the water will not lose too fast during the operation; if you do not add high-quality Retención de agua HPMC, the high temperature The operation will have quality problems such as insufficient hydration, reduced strength, cracking, hollowing and falling off caused by excessive drying, and it will also increase the difficulty of construction for workers.
If under non-summer and non-high temperature conditions, as the temperature drops, the amount of Retención de agua HPMC can be gradually reduced, so that the same water retention effect can be achieved.
