Calcined diatomite filler is an advanced functional inorganic material produced through high-temperature calcination (exceeding 1200°C) and precision classification of natural diatomite. This specialized process creates a stable porous structure with a substantial surface area of 50-150 m²/g, endowing the material with exceptional adsorption capacity while maintaining chemical inertness - properties that make it ideally suited for applications in coatings, environmental materials, and refractory products.The calcined diatomite filler delivers significant performance enhancements to composite materials, notably improving thermal stability and mechanical strength while reducing substrate shrinkage by over 30% in high-temperature applications. Its optimized dispersion characteristics and processing efficiency contribute to superior manufacturing outcomes.As an eco-friendly filler solution, this material offers both pollution-free composition and low-density advantages, enabling raw material reduction of approximately 15-20% in final products. These combined benefits support industrial manufacturers in achieving the dual objectives of performance enhancement and energy efficiency improvement, representing a meaningful upgrade for sustainable industrial production.

What are the advantages of calcined diatomite filler? | |
Calcined diatomite diatomite filler is a versatile material refined from natural diatomite through high-temperature calcination, offering three core advantages. First, its stable porous structure—achieved via calcination above 1200°C with a surface area of 50-150 m²/g—delivers exceptional adsorption capacity and chemical inertness, enabling efficient loading of functional additives for catalyst carriers, filtration media, and environmental adsorption applications.Second, the high-temperature process significantly enhances thermal stability and mechanical strength. When added to refractory products or high-temperature coatings, it elevates the substrate’s heat resistance beyond 1000°C while reducing the thermal expansion coefficient by 20%-30%, effectively preventing cracking or deformation under extreme heat.Additionally, its uniform particle size distribution and superior dispersibility ensure strong bonding with resins, ceramics, and other matrices, boosting compressive strength by 15%-20% and improving processing fluidity to reduce energy consumption. As an eco-friendly inorganic material free of volatile organic compounds, calcined diatomite filler meets sustainable production demands, lowering material costs while enabling high-performance, environmentally responsible industrial upgrades. | |
