The hydroxyethoxyl content of common commercial HEMC products currently on the market. The content of methoxyl ranges from 6% to 16%, and the content of methoxyl ranges from 18% to 27%. After an in-depth analysis of the product, it was found that the hydroxyethoxy and methoxy groups should be within the specified range, and the comprehensive performance is the best.

KimaCell® HEMC MH4M Cellulose ether is an admixture widely used in industrial drymix mortar, which has a great influence on the rheological properties of mortar. The increase of the cellulose ether content will lead to the increase of the initial torque of the mortar, but after a period of stirring, the flow resistance of the mortar will decrease instead; under the condition that the initial fluidity is basically the same, the fluidity loss of the mortar first decreases and then increases; the yield strength of the mortar Compared with starch ether and thickened powder, cellulose ether has higher viscosity and stability than starch ether and thickened powder.
