Hydroxypropyl methylcellulose is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processes. They are a kind of odorless, odorless, non-toxic white powder, which swells in cold water and is called clear or slightly cloudy colloidal solution. It has the properties of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, maintaining moisture and protecting colloid.
Excellent hydroxypropyl methylcellulose can effectively solve the problem of water retention under high temperature. In high temperature seasons, especially in hot and dry areas and thin-layer construction on the sunny side, high-quality HPMC hydroxypropyl methylcellulose is required to improve the water retention of the slurry.
High-quality hydroxypropyl methylcellulose has particularly good uniformity. Its methoxy and hydroxypropoxy groups are evenly distributed along the cellulose molecular chain, which can enhance the oxygen atoms on the hydroxyl and ether bonds and the water association. The ability to combine and 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.
