Diatomite paint is an indoor decorative wall material primarily made from diatomite. Due to its health and environmental benefits, it not only has excellent decorative properties but also functional properties, making it a new generation of indoor decorative materials.

Cellulose ethers are synthetic polymers derived from natural cellulose, a high-molecular-weight material. They are odorless, tasteless, and non-toxic white powders that swell in cold water to form clear or slightly turbid colloidal solutions. They possess properties such as thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surfactant activity, moisture retention, and colloid protection.

Hydroxypropyl methyl cellulose ether in diatomite paint offers excellent water solubility, rapid thickening and viscosity, superior water retention, high bonding strength, and excellent workability. Specifically, it provides the following benefits:

1. Enhances water retention, improving issues such as rapid drying and insufficient hydration of diatomite paint, which can lead to poor hardening and cracking.

2. Increases the plasticity of diatomite paint, improves workability, and enhances efficiency.

3. Ensures optimal adhesion of diatomite to substrates and bonded materials.

4. Acts as a thickening agent to prevent shifting of diatomite and bonded materials during application.

Additionally, hydroxypropyl methylcellulose offers the following advantages:

1. Consistent quality achieved through scientific formulation, large-scale automated production, and appropriate additives to meet special quality requirements;

2. Wide range of products, capable of producing various types of mortar and coatings with different performance characteristics according to specific requirements;

3. Excellent construction performance, easy to apply and spread, eliminating the need for pre-wetting of the substrate and post-water curing;

4. Convenient to use, easy to transport and store, and facilitates construction management;

5. Environmentally friendly, reducing environmental impact;

6. Cost-effective, dry-mixed mortar and coatings avoid unreasonable raw material usage due to optimized formulations, are suitable for mechanized construction, shorten construction cycles, and reduce construction costs.
