HPMC manufacturer-What Are the Main Raw Materials for Construction Plaster Putty? (1) Building gypsum powder Building gypsum powder is the main material of gypsum putty and is the basic material to ensure the bond strength and impact strength, therefore there are strict requirements on its quality. Physical properties Fineness: all passed through 120 mesh sieve. Initial […]
Read MoreHydroxypropyl methyl cellulose HPMC is used as a dispersant, thickener and binder in construction treatment, and is mainly used in the molding of cement mortar and gypsum products. It is used in cement mortar to increase its adhesion, reduce flocculation, improve viscosity and shrinkage,
Read MoreAs a Construction Grade Hpmc Manufacturer, share it with you.
Read MoreWhen HPMC is added to the plastering mortar, it increases water retention, allowing the cement to fully hydrate and improving bond strength as well as tensile and shear strength. As a result, the construction effect is greatly enhanced, and work efficiency improves.
Read MoreThe production process of HPMC is mainly a polysaccharide-based ether product produced by alkalization and etherification of wood pulp or cotton fibers (domestic). Since it has no charge, it reacts with no charged ions in the gelling material, and its performance is stable. In addition, it is less expensive than other types of cellulose ethers, which makes it ideal for dry mix mortars.

Read MoreThe redispersible polymer powder RDP can be quickly redispersed into an emulsion after contacting with water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high weather resistance and resistance to various High adhesion to various substrates. In addition, the latex powder with hydrophobicity can make the mortar have good water resistance.
