Industrial-grade diatomaceous earth, a high-performance natural mineral material processed from high-quality diatomite ore through crushing, calcination, purification, grinding, and classification, is widely used in industrial filtration, functional fillers, thermal insulation, environmental protection, and other fields due to its high porosity, low density, high adsorption, stable chemical properties, and high-temperature resistance. As an important industrial basic material, it plays an irreplaceable role in improving product performance, reducing production costs, and promoting green industrial development, and is widely recognized by global manufacturing and environmental protection industries.
Filtration is the largest application field of industrial-grade diatomaceous earth, accounting for more than 60% of global consumption. It is widely used in industrial water treatment, chemical liquid filtration, petroleum processing, swimming pool water purification, and other scenarios. Its unique porous structure can efficiently remove suspended solids, particles, and impurities in liquids, with high filtration efficiency, large flow rate, and long service life. In industrial circulating water treatment, it reduces turbidity, improves water quality, and saves water resources. In the chemical industry, it filters various solvents, resins, paints, and inks to ensure product purity and stability. In swimming pool filtration, it quickly removes impurities and microorganisms, keeping water clear and clean. In oilfield and petroleum processing, it effectively filters impurities in crude oil and lubricating oil, improving oil quality and equipment service life.
As a high-performance functional filler, industrial-grade diatomaceous earth is widely used in coatings, plastics, rubber, papermaking, and construction materials. Added to coatings and paints, it acts as a matting agent and reinforcing filler, reducing surface gloss, improving wear resistance, scratch resistance, and weather resistance, and shortening drying time. In plastics and rubber, it enhances hardness, tensile strength, aging resistance, and dimensional stability, reducing raw material costs and improving product durability. In papermaking, it improves paper whiteness, opacity, smoothness, and printability, widely used in high-grade cultural paper and packaging paper. In construction materials, it is used in thermal insulation boards, fireproof materials, and sound-absorbing panels, leveraging its low thermal conductivity and fire resistance to improve building energy efficiency and safety.
In the field of environmental protection and industrial safety, industrial-grade diatomaceous earth demonstrates excellent application value. Its high adsorption capacity makes it an ideal material for oil spill treatment, industrial wastewater purification, and harmful gas adsorption. It can quickly absorb oil, organic solvents, and odors, and is widely used in oil spill cleanup, industrial deodorization, and air purification. In agriculture, it serves as a natural insecticide and soil conditioner, physically controlling pests by damaging their waxy cuticles without polluting the environment, while improving soil permeability and fertility. In addition, it is used as a catalyst carrier in the chemical industry, providing a large specific surface area to improve catalytic efficiency and service life.
Thermal insulation is another important application of industrial-grade diatomaceous earth. Calcined diatomaceous earth has excellent high-temperature resistance and low thermal conductivity, and can be used stably for a long time at high temperatures. It is widely used in industrial furnace insulation, thermal insulation pipes, fireproof materials, and cryogenic insulation systems, with lightweight, high efficiency, and long service life, replacing traditional insulation materials and reducing energy consumption. In the metallurgical and ceramic industries, it is used as a refractory additive to improve the high-temperature stability and strength of materials.
