HPMC water retention

HPMC water retention 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. HPMC water retention 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.

Are the water retention capacity and the amount of HPMC water retention affected by the season?

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 HPMC water retention in different seasons.

2) In different seasons, the water retention effect of the slurry can be adjusted by increasing or decreasing the amount of HPMC water retention during specific construction. Promote mortar and gypsum to show different water retention.

The performance in specific operations is as follows:

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 HPMC water retention, 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 HPMC water retention can be gradually reduced, so that the same water retention effect can be achieved.
