Hydroxypropyl methylcellulose HPMC is mainly used in the molding of cement mortar and gypsum products as a dispersant, thickener and binder in building treatment. It is used in cement mortar to increase its cohesiveness, reduce flocculation, improve viscosity and shrinkage,

In the use of building materials, hydroxypropyl methyl cellulose HPMC is a commonly used building material additive, hydroxypropyl methyl cellulose is widely used in industry, and has different types, hydroxypropyl methyl cellulose can be divided into For cold water instant type and hot melt type.

As a common building material, hydroxypropyl methylcellulose HPMC is more important in the construction industry. What are the main functions of hydroxypropyl methylcellulose?

It comprises of cement, sand, limestone, cellulose ether (HPMC ,MEHC etc)  , Vinyl Acetate-Ethylene , and other additive.

The construction method of new cement based plastering mortar, construction preparation, basic treatment, metope paste cake and reinforcement, metope appropriate amount of watering, preparation of slurry, slurry scraping on the wall, scraping, compaction and polishing.

The light transmittance of hydroxypropyl methyl cellulose is mainly affected by the following points:

1. If the degree of polymerization of cellulose ether of hydroxypropyl methylcellulose is higher, its molecular weight will be larger, resulting in a higher viscosity of its aqueous solution.
