What is diatom mud?

Diatom mud is an indoor decorative wall material with diatomaceous earth as the main raw material. It has the functions of eliminating formaldehyde, purifying air, regulating humidity, releasing negative oxygen ions, fire retardant, self-cleaning wall, 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 nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. They are an odorless, tasteless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. It has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gelation, surface activity, moisture retention, and a protective colloid.

The function of hydroxypropyl methyl cellulose (HPMC) in diatom mud:

  • Enhanced water retention, improved diatom mud too fast drying and insufficient hydration caused by poor hardening and cracking.
  • Increase the plasticity of diatom mud, improve the workability and improve work efficiency.
  • Enhance the adhesive

 

Due to the thickening effect, it can prevent the diatom mud and the adherent from being scratched during construction.

Diatom mud itself does not have any pollution, it’s pure natural, and has a variety of functions, which is incomparable with traditional coatings such as latex paint and wallpaper. During the construction of diatom mud, it has no flavor and is purely natural. The selection of hydroxypropyl methylcellulose(HPMC) in diatom mud is high quality.
