Specific Index Performance of Industrial Construction Grade HPMC Powder

What are the main technical specifications of industrial construction grade HPMC powder?

The main indexes of industrial construction grade HPMC powder are hydroxypropyl content and viscosity. Hydroxypropyl content is high, water retention is generally better. Viscosity, water retention, relative (rather than absolute) is also better, and viscosity, in cement mortar better.
The most important function of industrial construction grade HPMC powder is water retention, followed by thickening. In putty powder, as long as the water retention is good and the viscosity is lower (70000-80000), it is also OK. Of course, if the viscosity is higher, the relative water retention is better. When the viscosity exceeds 100000, the viscosity has little effect on the water retention.
Industrial construction grade HPMC powder: it is OK with low requirements and viscosity of 100000. It is important to keep water better. It plays three roles of thickening, water conservation and construction in putty powder, and does not participate in any reaction.

The application of industrial construction grade HPMC powder mortar: it has higher requirements, the viscosity of more than 150000 is better, the high viscosity mortar is not easy to drop, it plays a role of water retention and thickening in the mortar, prevents the mortar from segregation and bleeding, and increases the workability and construction performance of the mortar.
