What factors affect the water retention of hydroxypropyl methylcellulose
The higher the viscosity of hydroxypropyl methylcellulose, the better the water retention performance. 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 are Haa...

Hydroxypropyl methyl cellulose in machine spray mortar
With the wide use of mortar, the quality and stability of mortar can be well guaranteed. However, since the dry-mixed mortar is directly processed and produced by the factory, the price will be higher in terms of raw materials. If we continue to use manual plastering on site, it will not be compe...

Summary of hydroxypropyl methylcellulose HPMC properties
Hydroxypropyl methyl cellulose HPMC is a kind of non-ionic cellulose mixed ether, which is different from ionic methyl carboxymethyl cellulose mixed ether, and it does not react with heavy metals. Due to the different ratios of methoxyl content and hydroxypropyl content in hydroxypropyl methylcel...
