Diatomite, also known as diatomaceous earth, belongs to biogenetic nonmetallic mineral formed by fossil remains of ancient diatoms. Its major constituent is amorphous silicon dioxide, accompanied by aluminium oxide, iron oxide and trace mineral components. The material possesses abundant interconnected micropores, large specificsurfacearea, low bulk density, outstanding adsorptive capacity, chemical inertness, soundinsulating and heatinsulating property, together with nontoxic characteristics. It conforms to domestic industry specification and REACH, RoHS exportrelated standards, and finds wideranging usage in liquid filtration, wastegas adsorption, functional fillers, green building materials, agricultureandfeed additives.
The processing workflow consists of rawore crushing, drying, calcination, milling and particlesize classification. Three mainstream grades include natural uncalcined diatomite, calcined diatomite and fluxcalcined diatomite. Premiumgrade finished goods keep intact diatom shell structure, uniform pore diameter and low ironcontaining impurities. In the filtration sector, it serves as the essential filteraid for edibleoil, wine, fruitjuice, syrup and industrial solvent, removing fine suspended particles and improving liquid clarity. For environmentalprotection applications, the porous framework absorbs formaldehyde, peculiar smell, ammonianitrogen and heavymetal pollutants in sewage and indoorair. When applied to construction materials, it manufactures breathable wall materials, heatinsulating boards and paint filler for humidity adjustment and harmfulgas decomposition. Within agriculture and breeding industries, it acts as anticaking additive, pesticide carrier and physical insect repellent.
Major qualitytesting parameters cover silicondioxide proportion, porosity, specific surface area, whiteness, moisture content, particle mesh size and heavymetal content. Our enterprise supplies multiple mesh specifications and customized granular products. We offer sample inspection, formulation consultation and stable bulk supply for domestic clients and overseas trade buyers.
