Hydroxypropyl methylcellulose ether (HPMC) has the function of water retention and thickening in cement mortar and gypsum-based mortar, and can reasonably improve the adhesion and vertical resistance of mortar.

Factors such as gas temperature, temperature and gas pressure rate are harmful to the evaporation rate of moisture in cement mortar and gypsum based products. Thus, the same total amount of commercial hydroxypropyl methylcellulose ether (HPMC) added to maintain water utility varies from season to season.

In concrete pouring, the actual effect of water lock can be adjusted according to raising and lowering the high fraction total flow. The water locking rate of hydroxypropyl methyl cellulose ether at high temperature is the key index value to distinguish the quality of hydroxypropyl methyl cellulose ether.

High-quality hydroxypropyl methyl cellulose ether (HPMC) products can reasonably handle the problem of high temperature water locking. In high temperature seasons, especially in hot and humid areas and chromatographic engineering buildings, high-quality hydroxypropyl methyl cellulose ether (HPMC) is required to improve the water solubility of the slurry.

High-quality hydroxypropyl methyl cellulose ether (HPMC) is very well-proportioned, and its methoxy group and hydroxypropyl group are evenly distributed on the molecular structure chain of methyl cellulose, which can enhance the generation of oxygen molecules on hydroxyl and ether bonds. The ability of covalent bonds to work.

It can reasonably control the volatilization of water caused by hot weather, and achieve the actual effect of high water lock. High quality hydroxypropyl methylcellulose ether (HPMC) can be found throughout mixed mortar and plaster of paris crafts.

All solid particles are encapsulated to produce a wet film, and the conventional moisture is slowly released for a long time, and undergoes coagulation reaction with inorganic materials and collagen materials to ensure the bonding compressive strength and tensile strength.

Therefore, in the high temperature summer construction site, in order to achieve the actual effect of water saving, people must add high-quality hydroxypropyl methyl cellulose ether (HPMC) products according to the secret recipe, otherwise, it will be due to lack of coagulation, reduced compressive strength, Cracks, gas drums and other product quality problems cause excessive drying.

This also increases the difficulty of construction for workers. With the decrease of temperature, the addition amount of hydroxypropyl methyl cellulose ether (HPMC) is gradually reduced, and the same moisture can be achieved.
