The application of hydroxypropyl methylcellulose is very extensive, and it has a lot to do with its viscosity, and the viscosity required for different uses of hydroxypropyl methylcellulose is also different, so when we use its products First of all, we should know what its viscosity is, but the viscosity of hydroxypropyl methylcellulose is affected by many factors. If the storage is not careful, it may cause its viscosity to fail. So for hydroxypropyl methylcellulose, What factors are its viscosity related to? Let me introduce you briefly.
Generally, the viscosity of hydroxypropyl methylcellulose will be affected by the following factors:
1. The higher the degree of polymerization of cellulose ether and the larger the molecular weight, the higher the viscosity of its aqueous solution;
2. The higher the dosage (or concentration) of cellulose ether, the higher the viscosity of its aqueous solution, but care should be taken to select the appropriate dosage when using it, so as not to affect the performance of mortar and concrete if the dosage is too high;
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 influence of temperature;
Generally, when we control the viscosity of hydroxypropyl methylcellulose, we observe from the above points, so we should check and use it many times when storing hydroxypropyl methylcellulose
