In the dry mixed ready mixed mortar, the addition of hpmc is very low, but it can improve the performance of wet mortar. The reasonable selection of different varieties, different viscosities, different particle sizes, different viscosities and different amounts of cellulose ethers has an impact on the improvement of the performance of dry powder mortar. At present, many masonry and plastering mortars have poor water retention performance, and water slurry separation will occur after a few minutes of standing. Water retention is an important performance of methyl cellulose ether, and it is also the performance concerned by many domestic dry powder mortar manufacturers, especially those in the regions with high temperature in the south. The factors affecting the water retention effect of dry powder mortar include the amount of hpmc, the viscosity of hpmc, the fineness of particles and the temperature of the environment. Hydroxypropyl methylcellulose (hpmc) is a kind of synthetic polymer, which is made from natural cellulose by chemical modification.

Polycarboxylate superplasticizer is a concrete admixture with high water reducing rate and low slump loss.

HPMC products for construction are widely used to improve the performance of hydraulic building materials, such as cement and gypsum. In cement-based mortar, it can improve water retention, extend correction time and opening time, and reduce sagging phenomenon.

Nov 11 has been a shopping festival in China recently.So we organize an online activity for giving back to our new®ular customers.

1. Masonry mortar plastering mortar High water retention can fully hydrate cement. Significantly increase the bond strength. At the same time, the tensile and shear strength can be appropriately improved. Greatly improve the construction effect and work efficiency.
