The Way to Measure the Viscosity of Hydroxypropyl Methylcellulose HPMC

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.

What is the main function of the application of hydroxypropyl methyl cellulose in putty powder? Is there a chemical reaction?

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.

Hydroxypropyl methyl cellulose (HPMC) product characteristics
1. Properties: This product is a white powder, and is odorless, tasteless and non-toxic.

Hydroxypropyl methyl cellulose manufacturers analyze and test hydroxypropyl methyl cellulose

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.
