Effect of hydroxypropyl methylcellulose on diatom mud
Diatom mud is an indoor decorative wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire prevention and flame retardant, wall self-cleaning, sterilization and deodorization. As diatom mud is healthy and environmentally friendly, it not only has good decoration, but also has functionality. It is a new generation of interior decoration material instead of wallpaper and emulsion paint.
Hydroxypropyl methyl cellulose for diatom mud is a non-ionic cellulose ether made from natural polymer cellulose through a series of chemical processing. They are odorless, tasteless and non-toxic white powders that swell into clear or slightly turbid colloidal solutions in cold water. It has the characteristics of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gel, surface activity, water retention and protective colloid.
Role of hydroxypropyl methylcellulose in diatom mud:
Enhance water retention and improve the phenomena of poor hardening and cracking caused by too fast drying and insufficient hydration of diatom mud.
Increase the plasticity of diatom mud, improve construction operability and improve work efficiency.
Fully enable it to better bond the substrate and the bonded object.
Due to its thickening effect, it can prevent the scratch of diatom mud and bonded objects during construction.
Diatom mud itself has no pollution, is pure natural, and has a variety of functions, which is unmatched by traditional coatings such as latex paint and wallpaper. There is no need to move when decorating with diatom mud, because there is no taste during the construction of diatom mud. It is pure natural and easy to repair. Therefore, diatom mud has high requirements for the selection of hydroxypropyl methylcellulose.
