hpmc manufacturer-How to choose the viscosity of hydroxypropyl methylcellulose?
1) Putty powder, tile adhesive, caulking agent, bonding mortar, plastering mortar, etc. can be used up to 100,000 viscosity hydroxypropyl methylcellulose.
2) The standard of vitrified microbead insulation mortar is higher. It requires 150,000 viscosity hydroxypropyl methylcellulose or 200,000 viscosity hydroxypropyl methylcellulose. If you choose 100,000 viscosity, it is very easy to form a flow. Hanging phenomenon.
3) The key function of cellulose is water retention, followed by thickening. In putty powder, if the water retention is good, the viscosity is lower (70,000-80,000). When the viscosity exceeds 100,000, the viscosity has little effect on the water retention. The production of putty is better without choosing The viscosity of 200,000, because the viscosity is too large, there will be difficult to scrape, scraping and sinking.
