The advanges of HPMC & MHEC in dry mix mortar products
November 22nd 2024
Hydroxypropyl methylcellulose is now used in all walks of life. What kind of raw material is it?
From a physical point of view, hydroxypropyl methylcellulose is a non-ionic cellulose ether, white powder, without taste. In the construction industry, it can be used as a water retaining agent and retarder for cement mortar to make the mortar pumpable.
The following are some properties of hydroxypropyl methylcellulose:
1. With its good stability, emulsion and water-soluble resin coatings can be used as emulsifiers, stabilizers and thickeners, etc., so as to make the coating wear resistance and adhesion, and allow stable pH value.
2. It has water retention. The main function of hydroxypropyl methyl cellulose putty powder is that I can retain water for lubrication and adhesion. It improves shrinkage resistance and self-skinning to prevent the phenomenon of powder.
3. It has good dispersibility in synthetic resin. Protective agent, hydroxypropyl methyl cellulose can play an important role to prevent aggregation of polymer particles and improve the stability of resin particle dispersion.
In addition to these properties, hydroxypropyl methylcellulose, as well as good thickening, strong adhesion, construction and other characteristics, it can be seen that its performance is very good. Because these functions are widely used in many industries, such as construction industry, coating industry, etc., to make hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose is indispensable.
