construction hpmc-HPMC plays three roles in putty powder HPMC plays three roles in putty powder: thickening, water retention and construction. Thickening: The cellulose thickens the putty powder and helps to suspend it and keep it in a uniform solution. Water retention: It makes the putty powder dry slower and assists the reaction of calcium ash under […]

cellulose hpmc-Application Fields Of Hydroxypropyl Methylcellulose In Various Building Materials Application Fields Of Hydroxypropyl Methylcellulose In Various Building Materials Hydroxypropyl methylcellulose In dry mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive that affects the performance of mortar construction. The […]

HPMC manufacturer-The main effect of HPMC on mortar construction Overview of Cellulose Ether-HPMC For modern building mortar, it is required to have suitable construction consistency and water retention, delay the loss of water in the mortar, prolong the operation time and open time (opening time), enhance wet viscosity and cohesion after setting and hardening, and […]

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 […]

Hydroxypropyl 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,

As a Construction Grade Hpmc Manufacturer, share it with you.

When 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.

The 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.
