Today, what is the viscosity of hydroxypropyl methylcellulose aqueous solution?

1. The relative molecular mass of cellulose ether, the temperature of the aqueous solution, the cutting rate, and the experimental method;

2. The higher the glass transition temperature, the higher the relative molecular mass, and the higher the viscosity of the solution;

3. The higher the content of cellulose ether, the higher the viscosity of its solution. Therefore, we should pay attention to the appropriate dosage when implementing the application to prevent the dosage from being too high, which will directly affect the cement mortar and cement concrete. characteristic;

4. Like most solutions, the viscosity will also decrease with the increase of temperature. In addition, the higher the content of cellulose ether, the greater the harm to the temperature; in addition, the actual thickening The effect also varies according to the water consumption of the epoxy cement material.
