1. HPMC element uniformity Homogeneous reaction of hydroxypropyl methyl cellulose, methoxy, hydroxypropoxy evenly distributed, high water retention rate.

Hydroxypropyl methylcellulose is used as a water-retaining agent in cement mortar and retarder for mortar pumping.

High-quality HPMC can be evenly and effectively dispersed in cement mortar and gypsum based products, and wrap all solid particles, and form a layer of wetting film. The moisture in the base is gradually released over a long period of time, and hydrates with inorganic cementitious materials, thus ensuring the bonding strength and compressive strength of the materials. Therefore, in high temperature summer construction, in order to achieve the water retention effect, it is necessary to add enough high-quality HPMC products according to the formula, otherwise, quality problems such as insufficient hydration, strength reduction, cracking, hollowing and falling off caused by drying too fast will occur, and the construction difficulty of workers will also be increased. As the temperature decreases, the amount of HPMC can be gradually reduced, and the same water retention effect can be achieved.
