Diatomaceous earth filter aid
Offering unmatched UV protection, this light and soft diatomaceous earth is a premium filler that eliminates leather pollution. Its neutral pH, non-toxic nature, and smooth, powdery texture provide excellent strength, UV resistance, and high temperature endurance. Perfect for applications in paints, coatings, and waste treatment industries.
Pesticide industry
With a neutral pH and non-toxic profile, this diatomaceous earth boasts extraordinary suspension performance and strong adsorption. Its light weight and high oil absorption rate (115%) ensure perfect mixing uniformity, preventing blockages in agricultural machinery pipelines. Ideal for composite fertilizers used in fruit, vegetable, and flower cultivation, it enhances soil moisture retention, soil aeration, and promotes crop growth by extending fertilizer efficacy.
Rubber industry
When used as a filler for vehicle tires, rubber tubes, triangle belts, conveyor belts, and car pads, diatomaceous earth significantly boosts the rigidity and strength of these products. With a high settlement volume of 95%, it improves heat resistance, wear resistance, thermal insulation, and anti-aging properties, ensuring the durability and longevity of rubber products.
Paint, coating industry
A top-tier filler providing excellent UV protection, lightweight, and soft texture, diatomaceous earth eliminates leather pollution. With its neutral pH and non-toxic qualities, it offers a smooth, powdery finish that delivers superior strength and high-temperature resistance. Ideal for paints, coatings, and waste treatment applications.
Home industry
In the home industry, diatomaceous earth is predominantly used in bathroom mats, foot mats, toilet mats, and tableware trays. These products excel at absorbing and decomposing moisture and odor, ensuring indoor air remains fresh and dry.
Construction industry:
In construction, diatomaceous earth's excellent moisture absorption, adsorption, and stability make it an ideal material for thermal insulation and external insulation for interior walls. It can also be applied to wall surfaces for enhanced waterproofing, moisture-proofing, and fireproofing properties.
Health industry:
In the health sector, diatomaceous earth is used to create mineral face masks, diatomaceous earth mud, and other skincare products. These products effectively cleanse the skin, absorb impurities and toxins, and promote metabolism and cell regeneration.

Types:
1. Dried Products: After raw diatomite is dried at 100ºC~300ºC, it undergoes high-pressure gas flow pulverization and purification, followed by classification. The resultant product is grayish-white or light yellow.
2. Roasted Products: Produced by refining diatomite under high temperatures of 800ºC~900ºC, followed by high-pressure gas flow pulverization and classification, resulting in a reddish-orange product.
3. Aided-Melting Roasted Products: Cleaned diatomite is mixed with appropriate melting additives and roasted at 900ºC~1200ºC. This is followed by pulverization and classification, producing a white product.
