Specifically, building redispersible emulsion powder is a kind of building material, which is a combination of building powder and environmental protection glue in a certain proportion. Its use method is simple, the effect is remarkable, now it has been widely used in the construction field.

Redispersible polymer powder is a water-soluble redispersible powder, the most common is ethylene-vinyl acetate copolymer, and uses polyvinyl alcohol as a protective colloid. Therefore, redispersible polymer powder is very popular in the construction industry market.

The main Redispersible polymer powders currently used in the market are: vinyl acetate vinegar and ethylene copolymer latex powder (VAe/E), ethylene and vinyl chloride and lauric acid ethylene vinegar ternary copolymer latex powder (E/VC/VL), vinyl acetate vinegar and Ethene and higher fatty acid vinyl ester ternary copolymer latex powder

Construction Industry: HPMC,As Cement mortar water-retaining agent, retarder so that mortar with pumping. In the plaster, Gypsum Material, putty powder or other building materials, as an adhesive, improve smear and extend the operating time.

In ready-mixed mortar, the addition amount of hydroxypropyl methylcellulose is very low, but it can significantly improve the performance of wet mortar and is a major additive that affects the construction performance of mortar.

Powder mixing method: the HPMC powder and a large number of other powdery material ingredients, fully mixed with a blender, after adding water to dissolve, then the HPMC can be dissolved at this time, without agglomeration, because each tiny little corner, only a little HPMC powder

Hydroxypropyl methyl cellulose has unique properties in the application of construction materials, from mixing to dispersion to construction, as follows.

The dispersible emulsion powder is dispersed and molded in the mold as a second binder to enhance the adhesion; the protective colloid is absorbed by the mortar system (it will not be destroyed after the mold is molded. or secondary dispersion);

In premixed mortar, only a little HPMC can significantly improve the performance of wet mortar, which shows that HPMC is a major additive affecting the construction performance of mortar.
