The product is a non-ionic cellulose ether in the shape of white powder, odorless and tasteless. In cold water, it swells into a clear or slightly turbid colloidal solution. It has thickening, adhesion, dispersion, emulsification, film-formation, suspension, gelation, surface activity,
Hydroxypropyl methylcellulose mainly plays the role of water retention and thickening in cement mortar and gypsum based slurry, and can effectively improve the adhesion and sag resistance of slurry.
Cellulose products are all derived from natural cotton pulp or wood pulp, which are obtained through etherification. Different cellulose products use different etherification agents. Hydroxypropyl methylcellulose HPMC uses other types of etherification agents (chloromethane and propylene oxide), and hydroxyethyl cellulose HEC uses etherification agents. ethylene oxide.
Water-retaining agent: Self-leveling materials are constructed on the ground base, and the construction thickness is relatively thin, and the water is easily absorbed by the ground base, resulting in insufficient hydration of the material, cracks on the surface, and reduced strength.
