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 air, adjusting humidity, releasing negative oxygen ions, fire retardant, wall self-cleaning, sterilization and deodorization, etc. 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 processes. They are an odorless, tasteless and nontoxic white powder that swells into a clear or slightly cloudy colloidal solution in cold water. It has thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, moisture-retaining and protective colloid properties.
The role of hydroxypropyl methylcellulose in diatom mud:
1. Enhance water retention, improve diatom mud over-drying and insufficient hydration caused by poor hardening, cracking and other phenomena.
2. Increase the plasticity of diatom mud, improve construction workability, and improve work efficiency.
3. Fully make it better bond the substrate and the adherend.
4. Due to its thickening effect, it can prevent the phenomenon of diatom mud and adhered objects from moving during construction.
Diatom mud itself has no pollution, is pure natural, and has many functions, which is incomparable to traditional paints such as latex paint and wallpaper. When decorating with diatom mud, there is no need to move, because diatom mud has no smell during the construction process, it is pure natural, and it is easy to repair. Therefore, diatom mud has relatively high requirements for the selection of hydroxypropyl methylcellulose.
