What are the reasons that affect the water retention of hydroxypropyl methyl cellulose?
The greater the viscosity of hydroxypropyl methyl cellulose, the better the water retention. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to measure the viscosity of HPMC. The main methods include HaakeRoto...Read more -
Study on common admixture of ready – mixed mortar
Pre-mixed mortar can be divided into wet mixed mortar and dry mixed mortar according to the production mode. The wet mixed mortar formed by adding water is called wet mixed mortar, and the solid mixture formed by mixing dry materials is called dry mixed mortar. There are many raw materials involv...Read more -
