Flux-calcined diatomite filler is a key component in the application of diatomite. It is an eco-friendly functional filler made from high-purity diatomite through a flux-calcination process. Its unique microporous structure is optimized under high temperatures, featuring a large specific surface area, strong adsorption capacity, and high chemical stability. This product is widely used in paints, coatings, film-printing materials, plastics, rubber, and other industries.Through precise temperature-controlled calcination, the porosity and mechanical strength of the filler are effectively enhanced while retaining the natural eco-friendly properties of diatomite. As a highly efficient porous medium, flux-calcined diatomite filler poses no risk of secondary pollution, helping enterprises achieve cost reduction, efficiency improvement, and sustainable development goals simultaneously.

What are the advantages of the Flux-Calcined Diatomite Filler? | |
Flux-calcined diatomite filler, with its unique processing and performance advantages, has become an ideal choice for industrial applications.First, the flux-calcination process creates a uniform microporous structure in the diatomite filler, delivering a specific surface area of 300–500 m²/g—far exceeding the adsorption capacity of conventional fillers.Second, it exhibits excellent chemical stability, resisting acids, alkalis, and high temperatures (withstanding over 800°C). Even in harsh environments such as exhaust gas purification or corrosive media, it maintains stable performance, extending equipment service life. Eco-friendliness is a key competitive advantage of flux-calcined diatomite filler. Made from natural diatomite and free from harmful additives during calcination, the product complies with ISO triple-system certifications, ensuring non-toxicity and eliminating secondary pollution risks—perfect for green manufacturing.Additionally, its mechanical strength increases by 30%, offering superior compression and wear resistance. Lastly, flux-calcined diatomite filler is versatile, suitable for rubber, plastics, wear-resistant materials, dental impression compounds, paints, coatings, and more. With its high efficiency, durability, and environmental benefits, this product is gradually replacing traditional fillers, driving cleaner industrial production and more efficient resource utilization. | |
