(HPMC)What are the factors that affect the viscosity of hydroxypropyl methyl cellulose?

Hydroxypropyl methyl cellulose is widely used, and its viscosity has a great relationship, and hydroxypropyl methyl cellulose for different purposes. The required viscosity is different, so when we are using its products. We should first understand its viscosity, but hydroxypropyl methyl cellulose viscosity is influenced by many factors. If the storage is not careful, is likely to cause its viscosity failure, so for hydroxypropyl methyl cellulose. Its viscosity and what factors?Simple introduction for you next.(HPMC)

The viscosity of hydroxypropyl methyl cellulose is generally affected by the following factors:
  • 1.The higher the polymerization degree of cellulose ether, the greater the molecular weight, the higher the viscosity of its aqueous solution.
  • 2.The higher the mixing amount (or concentration) of cellulose ether, the higher the viscosity of its aqueous solution. But attention should be paid to choosing the appropriate mixing amount when using, so as to avoid too high mixing, which affect the working performance of mortar and concrete.
  • 3.Like most liquids, the viscosity of cellulose ether solution will decrease with the increase of temperature, and the higher the concentration of cellulose ether, the greater the impact of temperature.

Generally, when we control the viscosity of hydroxypropyl methylcellulose, from the above points, so we should check and use the viscosity of hydroxypropyl methylcellulose for multiple times.
