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, and has no 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, emulsions and water-soluble resin coatings can be used as emulsifiers, stabilizers and thickeners, etc., so as to make the coating wear-resistant and adhesive, and allow stable PH value.
2. It has water retention. The main function of hydroxypropyl methylcellulose putty powder is that I can retain water and play the role of lubrication and adhesion. It improves shrink resistance and self-skinning to prevent powdering phenomenon.
3. It has good dispersibility in synthetic resins. As a protective agent, hydroxypropyl methylcellulose can play an important role in preventing aggregation of polymer particles and improving 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 of these functions, hydroxypropyl methylcellulose is widely used in many industries, such as construction industry, coating industry, etc., and hydroxypropyl methylcellulose is indispensable.
