Cellulose ethers are currently the commonly used polymer admixtures of the cement mortar used in construction. Cellulose ethers can be fully dispersed in water to form a transparent viscous liquid. With a small amount (the mass percentage of less than 1%) added to the cement, it can improve the flow and condensation characteristics of cement.. read more →

The cellulose ether can be used as the water-retaining agent. The water retention effects of cellulose ether can prevent the substrate from absorbing moisture too much and too fast, and can prevent the evaporation of water, in order to ensure sufficient water during hydration of cement. Generally speaking, the water-holding capacity of cement slurry will.. read more →

As an additive for cement mortar, the cellulose ether usually has an addition amount not more than 2% of cement mass. For the study on cellulose ether, there has been a long history of research abroad. For example, DOW had successfully developed and marketed as early as 1938. First, the higher viscosity the cellulose ether.. read more →

In the formulations of building materials, the dosage of cellulose ether is only 0.1% to 1%. But it plays an irreplaceable role. Various applications of cellulose ether in building materials will be introduced as follows. 1. Latex and Latex Building Materials Such cellulose derivatives as MC, CMC, HEC and HPMC can be used in the.. read more →

The water retention property of HPMC is also related to the temperature used, and will decrease with increasing temperature. But in the actual material application, in many circumstances, the dry mortar is often used in construction under the conditions of high temperature (above 40 degrees). In the case of plastering for exterior wall putty under.. read more →

As for the particle size, the finer the particle is, the better the water retention property will be. When cellulose ethers of large particles are in contact with water, the surface will be immediately dissolved to form a gel and wrap the materials up so as to prevent water molecules from continuing to penetrate. Sometimes.. read more →

1. CMC and HPMC added to the mortar can play the dual role of water retention and thickening. With the increase of dosage, the layering degree of mortar will decrease. CMC is an ionic cellulose ether, and can react with Ca(OH)2 when added to the mortar. CMC has no obvious improvement in the water retention.. read more →

With the continuous development of China’s building ceramics industry, full polished glaze tiles, ceramic stone, thin sheets and other new products have begun to become popular on the market. New ceramic tile body of various water absorption rates and of different properties emerging, the bonding properties of traditional cement mortar have been difficult to meet.. read more →
