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, self-cleaning of walls, 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. Cellulose is made from natural polymer material cellulose through a series of chemical processes. They are odorless, tasteless and non-toxic white powders that swell into clear or slightly turbid colloidal solutions 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.
Hydroxypropyl methylcellulose has the following advantages:
1. Excellent quality, according to the scientific formula, large-scale automatic production, adding appropriate admixtures to ensure that the product can meet the special quality requirements;
2. Rich variety, can produce mortar and coating with various properties according to different requirements;
3. Good construction performance, easy to apply and scrape, eliminating the need for substrate pre-wetting and post-watering maintenance;
4. Easy to use, it can be used after adding water and stirring, which is convenient for transportation and storage, and convenient for construction management;
5. Green and environmental protection, no dust on the construction site, no various piles of raw materials, reducing the impact on the surrounding environment;
6. Economical. Due to the reasonable ingredients of dry-mixed mortar and paint, the unreasonable use of raw materials is avoided. It is suitable for mechanized construction, which shortens the construction period and reduces the construction cost.
