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, regulating humidity, releasing negative oxygen ions, fire prevention and flame retardant, wall self-cleaning, sterilization and deodorization. Because 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 materials instead of wallpaper and latex paint.
Diatom mud special hydroxypropyl methyl cellulose HPMC, is a natural polymer material cellulose as raw material, through a series of chemical processing and made of non-ionic cellulose ether. They are an odorless, tasteless, non-toxic white powder that expands into a clear or slightly cloudy colloid solution in cold water. With thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gel, surface activity, moisture retention and colloidal protection, etc.
The role of hydroxypropyl methyl cellulose HPMC in diatom mud:
Enhance water retention, improve diatom mud too fast drying and insufficient hydration caused by hardening, cracking and other phenomena.
Increase the plasticity of diatom mud, improve construction operability, improve work efficiency.
So that it can better adhere to the substrate and the adhesive.
Because of the thickening effect, it can prevent the phenomenon of diatom mud and the adhesives from being moved during construction.
Diatom mud itself does not have any pollution, pure natural, and has a variety of functions, is latex paint and wallpaper and other traditional coatings can not match. With diatom mud decoration is not to move, because in the construction of diatom mud in the process of no taste, is pure natural, easy to repair. So diatom mud on hydroxypropyl methyl cellulose HPMC selection requirements are relatively high.
