Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. It has the functions of eliminating formaldehyde, purifying the air, adjusting humidity, releasing negative oxygen ions, fire retardant, wall self-cleaning, sterilization and deodorization. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, but also functional. It is a new generation of interior decoration materials that replace wallpaper and latex paint.

Hydroxypropyl methylcellulose for diatom mud is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. It has the properties of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface-active, retaining moisture and protective colloid.

The role of hydroxypropyl methylcellulose in diatom mud:

1. Enhance water retention and improve the phenomenon of poor hardening and cracking caused by excessive drying and insufficient hydration of diatom mud;
2. Increase the plasticity of diatom mud, improve construction workability, and improve work efficiency;
3. Fully make it better to bond the substrate and the adherend;
4. Due to its thickening effect, it can prevent the phenomenon of diatom mud and the adhered material from being moved during construction.

Diatom mud itself does not have any pollution, it is pure natural, and has multiple functions, which is unmatched by traditional coatings such as latex paint and wallpaper. When decorating with diatom mud, there is no need to move, because there is no smell during the construction of diatom mud, it is pure natural, and it is easy to repair. Therefore, diatom mud has higher requirements on the selection of hydroxypropyl methylcellulose.
