Diatom mud is an environmentally friendly functional decorative material with diatomaceous earth as the main component. Its core component, Diatomaceous Earth, originated from the remains of ancient marine single-celled algae (diatoms). It was formed after hundreds of millions of years of deposition. The components are mainly silica (SiO₂), with a unique microporous sieve-like structure and natural ore. Material properties.

 Material Characteristic Analysis
1. **Porous structure and adsorption capacity**
   Diatom mud has 2-3 nanometer micropores, with a total porosity of up to 90%. Its adsorption capacity to harmful gases such as formaldehyde and benzene is 5,000 times that of activated carbon, and can effectively purify the air. Its specific surface area is 40-65㎡/g, and it can absorb moisture of 2.5 times its own weight, achieving automatic humidity adjustment.

2. **Environmental performance**
   Natural adhesive-free material, formed by mineral ion bonding, zero formaldehyde is released, and tested by GB/T 18883 air quality standard. The pH value remains in the weakly alkaline range of 8-9, and has natural anti-mold properties.

3. **Functional Compound**
   Modern technology often grafts nanophotocatalysts (TiO₂) into diatom micropores, which can catalyze the decomposition of pollutants under ultraviolet light or LED light sources, and upgrade traditional physical adsorption to chemical decomposition systems.

 Core application fields
 1. Building decorative materials
- **Wall System**: Replace latex paint/wallpaper, suitable for interior walls in residences, hotels, and hospitals
- **Functional ceiling**: Used with central air conditioning, control indoor humidity fluctuations ≤±5%
- Featured applications: Anti-condensation ceiling of underground parking lot, acoustic tuning wall of piano room

 2. Air purification products
- Purification module: embedded in fresh air system/air purifier, the measured benzene adsorption rate can reach 92%
- Formaldehyde decomposition board: Furniture surface treatment for composite boards, continuously decompose free formaldehyde
- Car purification pad: 2cm thickness product has a 72-hour removal rate of TVOC up to 81%

 3. Creative Design Field
- Art relief: strong plasticity, can make three-dimensional calligraphy, painting, cultural walls and other decorations
- Microlandscape carrier: porous structure adapts to the growth of plants such as moss, and is used in ecological installation art
- Handicrafts: made into vases, ornaments, etc., with natural humidity adjustment function

 4. Industrial environmentally friendly products
- Water treatment filter element: used for heavy metal ion adsorption with activated carbon
- Industrial dehumidifier: regenerated dehumidifier material, humidity response sensitivity up to ±3%RH
- Precision instrument moisture-proof box lining: maintain 45-55% RH gold storage humidity

The current market has derived sub-products such as photocatalyst, negative ion type, phase change temperature adjustment type, etc., and the application scenarios have expanded from the construction field to multiple dimensions such as environmental protection, art, and precision manufacturing, becoming a typical "function-decoration" composite material. . It should be noted that its physical adsorption characteristics require regular lighting maintenance, and the surface hardness (Mohs level 2-3) is lower than that of stone, so process optimization is required for different scenarios.
