Diatomite – The Largest Functional Porous Mineral Material

Diatomite is a natural porous siliceous rock formed by diatom remains over long periods. As the most widely used porous inorganic functional mineral globally, it is indispensable in building materials, coatings, filtration, environmental protection and agriculture. It features environmental safety, porosity, adsorption and cost-effectiveness. Main types include diatomite powder, calcined diatomite and flux-calcined diatomite.

1. Meticulous craftsmanship: Two production paths ensure controllable and traceable quality

（1）Natural mineral processing

Purified and processed from natural diatomite ore via crushing, drying, grinding and classification. It retains natural porous structure, low cost, suitable for general scenarios with high cost-performance requirements (ordinary coatings, agricultural additives, basic fillers).

（2）Chemical calcination and modification

Using precise processes such as high-temperature calcination, impurity removal, surface modification and activation. Raw materials can utilize mining tailings for recycling, in line with green production. Modified products have high purity , uniform particle size, stable porosity, meeting strict requirements of high-end coatings, food filtration and medical materials.

2. Core Features: Six Major Advantages Underpin "Abundant Value"

（1）Environmentally friendly and non-toxic, compliant and worry-free

Free of heavy metals, compliant with EU REACH, RoHS and Chinese national standards. Suitable for food contact, indoor coatings, children’s products and home decoration.

（2）Weather-resistant and lightfast, long-lasting and stable

Excellent UV resistance and thermal stability. No fading, chalking or aging for long-term outdoor use, stable in high-temperature and humid environments, ideal for exterior building systems.

（3）Acid and alkali resistant and corrosion resistant

Outstanding acid and alkali resistance, compatible with cement, latex and resin systems. Stable against chemical corrosion, widely used in anti-corrosion and waterproof coatings.

（4）Strong adsorption and excellent hiding power

High porosity and large specific surface area, effectively absorbing moisture, formaldehyde and odor. Good hiding power, reducing usage and lowering material cost.

（5）Good dispersibility and convenient construction

Fine and light powder, easy to disperse in water-based and solvent-based systems. Suitable for coatings, mortar, plastics and rubber, simple mixing and construction.

（6）Batch stability and controllable quality

Formal manufacturers adopt ISO 9001 quality management system, ensuring consistent whiteness, fineness and adsorption performance per batch, avoiding production losses.

3.Empowering all industries: From basic building materials to high-end manufacturing, covering all sectors

（1）Building Materials Industry

Interior and exterior wall coatings, putty, thermal insulation mortar: moisture-regulating, sound-absorbing, anti-cracking and environmentally friendly;Colored concrete and floor materials: good weather resistance and texture;Thermal insulation materials: light, low thermal conductivity, high safety.

（2）Plastics and Rubber Industry

Plastic fillers, cable materials, sealants: improve rigidity, heat resistance and dimensional stability, reduce cost while enhancing performance.

（3）Industrial Coatings and Environmental Protection

Filtration aids, sewage treatment, air purification: strong adsorption, efficient filtration and purification;Anti-corrosion and thermal insulation coatings: extend service life of steel structures and pipelines.
