What factors affect the viscosity of hydroxypropyl methylcellulose

In summary, the cohesion of mortar will be reduced due to the action of external force, which is also conducive to the scraping and construction of mortar, resulting in good cohesion and construction of mortar.

In summary, the cohesion of mortar will be reduced due to the action of external force, which is also conducive to the scraping and construction of mortar, resulting in good cohesion and construction of mortar. However, if the concentration of cellulose ether solution is low and the viscosity is low, it will show the characteristics of Newtonian fluid

What factors affect the viscosity of hydroxypropyl methylcellulose? It mainly depends on the following reasons.

1. If the degree of polymerization of cellulose ether of hydroxypropyl methylcellulose is higher, its molecular weight will be larger, resulting in higher viscosity of its aqueous solution.

2. If the amount or concentration of cellulose ether is higher, the viscosity of its aqueous solution will be higher. However, when using it, you should pay attention to choosing the appropriate amount of addition, mainly to avoid excessive addition, which will affect the working performance of mortar and concrete.

3. Hydroxypropyl methylcellulose Like most liquids, the viscosity of cellulose ether solution decreases with increasing temperature, and the higher the concentration of cellulose ether, the greater the temperature effect.

4. Cellulose ether solution is usually a pseudoplastic body with shear thinning characteristics. The greater the shear rate during the test, the lower the viscosity.

In summary, the cohesion of mortar will decrease due to the action of external force, which is also conducive to the scraping and construction of mortar, resulting in good cohesion and construction of mortar. However, if the cellulose ether solution is at a low concentration and low viscosity, it will show the characteristics of Newtonian fluid. When the concentration increases, the solution will slowly show the characteristics of pseudoplastic fluid, and the higher the concentration, the more obvious its pseudoplasticity.
