How does hydroxypropyl methylcellulose retain water?
August 4, 2020
Hydroxypropyl methyl cellulose is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing.They are an odorless, tasteless and non-toxic white powder that swells into a clear or slightly turbid colloidal solution in cold water.It has the characteristics of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid.
Excellent hydroxypropyl methylcellulose can effectively solve the problem of water retention at high temperature.In high temperature seasons, especially in hot and dry areas and thin-layer construction on the sunny side, high-quality HPMChydroxypropyl methylcellulose is required to improve the water retention of the slurry. High-quality hydroxypropyl methyl cellulose with very good uniformity. Its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose molecular chain, which can increase the oxygen atom and water association on the hydroxyl and ether bonds.The ability to combine to form hydrogen bonds turns free water into bound water, thereby effectively controlling the evaporation of water caused by high temperature weather and achieving high water retention.
