China HPMC viscosity

Viscosity is an important parameter for evaluating the performance of cellulose ethers. The higher the China HPMC viscosity, the better the viscosity of the cement-based material, the better the adhesion to the substrate, the stronger the anti-sagging and anti-dispersion ability, but if the viscosity is too large , It will affect the fluidity and operability of cement-based materials (such as sticking a plaster knife during plastering mortar construction). Therefore, the China HPMC viscosity used in dry-mix mortar is usually 15,000 to 60,000 mPa. S-1, self-leveling mortar and self-compacting concrete that require higher fluidity require lower China HPMC viscosity.

HPMCviscosity depends on the following factors:

1. The molecular weight (or degree of polymerization) and concentration of HPMC, solution temperature, and shear rate

2. The higher the degree of polymerization of HPMC, the higher the molecular weight, and the higher the viscosity of its aqueous solution;

3. The higher the content (or concentration) of HPMC, the higher the viscosity of its aqueous solution, but when using it, attention should be paid to selecting the appropriate content to avoid excessive blending and affecting the performance of mortar and concrete;

4. Like most liquids, HPMCviscosity will decrease with increasing temperature, and the higher the HPMC concentration, the greater the influence of temperature;

In addition, the thickening effect of HPMC will increase the water demand of cement-based materials, thereby increasing the output of mortar.


Viscosity is an important parameter for evaluating the performance of cellulose ethers. The higher the HPMCviscosity, the better the viscosity of the cement-based material, the better the adhesion to the substrate, the stronger the anti-sagging and anti-dispersion ability, but if the viscosity is too large , It will affect the fluidity and operability of cement-based materials (such as sticking a plaster knife during plastering mortar construction). Therefore, the HPMCviscosity used in dry-mix mortar is usually 15,000 to 60,000 mPa. S-1, self-leveling mortar and self-compacting concrete that require higher fluidity require lower HPMCviscosity.

HPMC solution is usually a pseudoplastic, which has the property of shear thinning. The higher the shear rate during the test, the lower the viscosity. Therefore, the cohesiveness of the mortar will be reduced due to the external force, which is beneficial to the scraping construction of the mortar, so that the mortar can have good workability and cohesion at the same time. However, HPMCsolution exhibits Newtonian fluid characteristics when the concentration is very low and the viscosity is small. When the concentration increases, the solution gradually exhibits pseudoplastic fluid characteristics, and the higher the concentration, the more obvious the pseudoplasticity.
