Hydroxyethyl Methyl Cellulose HEMC CAS No.9032-42-2

Overview of Hydroxyethyl Methyl Cellulose

Hydroxyethyl methyl cellulose (HEMC) is widely used in water-based emulsion coatings, building construction and building materials, printing inks, oil drilling, etc. It plays a role in thickening and water retention, improves workability, and is used in dry and wet mortar series products.

The role of hydroxyethyl methyl cellulose in cement mortar mainly includes the following aspects:

1. Increase the viscosity and adhesion of the mortar: hydroxyethyl methyl cellulose can increase the viscosity and adhesion of the cement mortar, making the mortar thicker, thus improving its resistance to cracking and impermeability.

2. Delay the hardening time of mortar: hydroxyethyl methyl cellulose in cement mortar can be used as a retarder to prolong the hardening time of mortar, which is favorable for construction operations.

3. Improve the construction performance of mortar: by increasing the hardening and application time, hydroxyethyl methyl cellulose can improve the performance of gypsum mortar and improve its compressive and twisting strength and spatial stability.

4. Improve the stability of mortar: hydroxyethyl methyl cellulose can improve the stability of mortar and reduce the phenomenon of water secretion, thus improving the overall performance of mortar.

The effect of hydroxyethyl methyl cellulose on the rheological properties of cement mortar:

1. Yield stress and plastic viscosity: the greater the viscosity of hydroxyethyl methyl cellulose, the more pronounced the delaying effect on the development of mortar yield stress and plastic viscosity. When the dosage is greater than 0.3%, both mortar yield stress and plastic viscosity increase with the increase of its dosage.

2. Time change: with the prolongation of time, the mortar yield stress will decrease, while the plastic viscosity increases with the increase of time.

The optimum dosage of hydroxyethyl methyl cellulose in cement mortar:

Studies have shown that the appropriate dosage of hydroxyethyl methyl cellulose in the finishing mortar of a ternary system of alumina cement-silicate cement-gypsum is 0.3% to 0.4%, which can enhance the whiteness resistance and stain resistance of the mortar, reduce the amount of water absorption, and improve the tensile bond strength, but it will reduce the flexural strength and compressive strength.
