Diatomaceous Earth Filter Aid
With robust sunscreen capabilities, light and soft texture, our Industrial Grade Diatomite Powder eliminates leather pollution and serves as a high-quality filler. Its light capacity, neutral pH, non-toxic nature, and smooth powdery consistency, coupled with excellent strength and high-temperature resistance, make it indispensable in paints, coatings, and sewage treatment industries.
Pesticide Industry
Our diatomaceous earth, with a neutral pH and non-toxic properties, exhibits excellent suspension performance and strong adsorption. It is lightweight, boasts an oil absorption rate of 115%, and ensures good mixing uniformity without clogging agricultural machinery pipelines. It enhances soil moisture, loosens soil structure, prolongs fertilizer efficacy, and promotes robust crop growth, making it perfect for composite fertilizers in fruits, vegetables, flowers, and other crops.
Rubber Industry
Utilized as a filler in vehicle tires, rubber tubes, triangle belts, rubber rolling, conveyor belts, car pads, and other rubber products, our diatomaceous earth significantly enhances rigidity and strength. With a settlement volume of 95%, it also improves heat resistance, wear resistance, thermal insulation, and anti-aging properties, making it a vital component in the rubber industry.
Paint, Coating Industry
Renowned for its strong sunscreen attributes, light and soft texture, our diatomaceous earth eliminates leather pollution and is a top-quality filler. It features a light capacity, neutral pH, non-toxic properties, smooth powder, and excellent strength, making it perfect for paints, coatings, and sewage treatment industries with high-temperature resistance.
Home Industry
In the home sector, diatomaceous earth is predominantly utilized to create products like bathroom mats, foot mats, toilet mats, and tableware trays. These products efficiently absorb and decompose moisture and odors, maintaining a fresh and dry indoor environment.
Construction Industry:
In construction, thanks to its superior moisture absorption, adsorption, and stability, diatomaceous earth can be used as thermal insulation or external insulation for building interiors. Additionally, it can be applied to wall surfaces for waterproofing, moisture-proofing, fireproofing, and other external protective measures.
Health Industry:
In the health industry, diatomaceous earth is used to create mineral masks, mud packs, and other products. These applications help cleanse the skin by absorbing dirt and toxins, promoting metabolism, and aiding cell regeneration.

Product Types:
1. Dried Products: After the raw diatomite is dried at temperatures ranging from 100ºC to 300ºC, it undergoes pulverization and purification using high-pressure gas flow. The product is then classified and emerges as gray-white or light yellow.
2. Roasted Products: This type is produced from refined diatomite that is roasted at high temperatures between 800ºC and 900ºC. Utilizing high-pressure gas flow for pulverization and classification, the resulting product has a distinctive reddish-orange hue.
3. Aided-Melting Roasted Products: Cleaned diatomite is mixed with appropriate amounts of a melting additive and then roasted at temperatures ranging from 900ºC to 1200ºC. Following pulverization and classification, the product turns white.
