KimaCell® MHEC MH60M methyl hydroxyethyl cellulose thickening is an important modification effect of cellulose ether on cement-based materials. Cellulose ether can endow the wet mortar with excellent viscosity, significantly increase the bonding ability between the wet mortar and the base layer, and improve the anti-sag performance of the mortar.

Application of MHEC MH60M

Kima Chemical MHEC MH60M methyl hydroxyethyl cellulose is used in cement slurry plaster and the increase rate of viscosity increase continuously. The molecular network structure of cellulose ether and the network structure of cement hydration products are intertwined, and the initial hydration of cement indirectly increases the concentration of cellulose ether, so that the viscosity of cellulose ether solution and cement slurry has a "composite superposition effect", cellulose ether The viscosity of the modified cement slurry is much greater than the sum of their respective viscosities.

Both cellulose ether modified cement slurry and pure cement slurry have the property of shear thinning or pseudoplasticity; the pseudoplasticity of cellulose ether modified cement slurry is lower than that of pure cement slurry; the lower the rotation rate, or the cellulose ether modified The lower the viscosity of cement slurry, or the lower the content of cellulose ether, the more obvious the pseudoplasticity of cellulose ether modified cement slurry.

As the temperature continues to rise, the speed and degree of cement hydration increase, so that the viscosity of pure cement slurry gradually increases. Due to the different ability of different types and amounts of cellulose ethers to inhibit cement hydration, the viscosity of the modified cement paste varies with temperature.
