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

HPMC for diatom mud is a non-ionic cellulose ether made from natural polymer cellulose through a series of chemical processing. It is an odorless, tasteless and non-toxic white powder that swells into a clarified or slightly turbid colloidal solution in cold water. HPMC has the properties of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, gel, surface activity, moisture retention and colloidal protection.

1.Improve the water retention:

Diatom mud has water absorption, and HPMC can improve the drying and excessive hydration of diatom mud caused by poor hardening and cracking. It can ensure the construction performance and finished product quality of diatom mud by enhancing water retention.

2.Improve Work Efficiency:

HPMC increased the plasticity of diatom mud and improved the working performance of construction. It is more convenient for the construction and the work efficiency is improved.

3.Thickening: 

Due to its thickening effect, HPMC can prevent the scratching, displacement and adhesion of diatom mud during construction. This helps to maintain the uniformity and consistency of the diatom mud, ensuring the construction and the final decorative effect.

4.Improve adhesion: 

HPMC can make the diatom mud better bond to the substrate and the bonded material, and improve the bond strength. HPMC can ensure strong bond between the diatom mud and the wall or other substrate.

5.Environment: 

Diatom mud is a kind of pure natural, does not have any pollution. Therefore, when choosing HPMC as an additive, it is necessary to ensure that its selection requirements are high to ensure that it is coordinated with the natural environmental protection properties of diatom mud.

In conclusion, HPMC plays an important role in improving construction performance, increasing working efficiency and strengthening bonding strength in diatom mud. It also plays the excellent performance of diatom mud and ensure its environmental protection.
