Increase the viscosity of hydroxypropyl methylcellulose in use

Adding some water-soluble polymer compounds can make the hydroxypropyl methylcellulose annual higher, such as mixing a certain amount of starch ether, polyvinyl alcohol and vegetable gum into the hydroxypropyl methylcellulose solution. The viscosity of methyl cellulose was higher than before the addition.

The viscosity of hydroxypropyl methylcellulose has a certain relationship with its molecular weight. The larger the molecular weight, the higher the viscosity.

The viscosity of hydroxypropyl methyl cellulose is greatly affected by temperature. Generally, the higher the temperature, the smaller the viscosity of hydroxypropyl methyl cellulose. Therefore, in the process of improving the viscosity of hydroxypropyl methyl cellulose, we It can be adjusted by controlling the temperature of the environment in which hydroxypropyl methylcellulose is used. However, if stored at room temperature, its viscosity and performance are relatively stable.

Acid and alkali also have a certain influence on the viscosity of hydroxypropyl methyl cellulose. Acid and alkali have no effect on the performance of hydroxypropyl methyl cellulose. Base cellulose plays a role.
