By mastering the science of thermal modification, sjzhuabang has developed a versatile portfolio including Washed, Metakaolin, and Calcined Kaolin to address the evolving needs of the construction, coatings, and polymer industries. Available for immediate export to Europe, Southeast Asia, and the Middle East, our high-purity minerals provide the precision performance required to optimize product quality while significantly reducing raw material costs.
[H2] Thermal Engineering: Unlocking the Triple Potential of Kaolin
[H3] Metakaolin: The High-Activity Pozzolan for Advanced Concrete In the global infrastructure market, durability is paramount. By calcining ultra-fine washed kaolin within a precise 600°C–900°C window, sjzhuabang produces a highly reactive Metakaolin. With an activity index exceeding 80%, our Metakaolin serves as a superior pozzolanic admixture, significantly enhancing the compressive strength and chloride ion resistance of high-performance concrete. It is the definitive choice for modern skyscrapers and marine engineering projects seeking long-term structural integrity.
[H3] Calcined Kaolin: The Ultimate Brightening & Opacifying Agent For the coatings and plastics industries, whiteness and opacity are the keys to market success. Through high-temperature calcination at 950°C–1250°C, sjzhuabang’s Calcined Kaolin achieves a super-high whiteness of 93%–96%. Its unique porous lamellar structure provides exceptional light scattering properties, allowing manufacturers to partially replace expensive Titanium Dioxide (TiO2) without compromising hiding power or surface finish, delivering a superior ROI for cost-conscious producers.

[H2] Frequently Asked Questions (FAQ) for Global Buyers
Q: Can sjzhuabang Calcined Kaolin truly replace Titanium Dioxide (TiO2)? A: While it is not a 1:1 replacement, our high-whiteness calcined kaolin can typically replace 15%-25% of TiO2 in many paint and plastic formulations. This allows for significant cost savings while maintaining excellent opacity and brightness.
Q: How does hezhensy ensure the batch-to-batch consistency of its Metakaolin? A: We use automated temperature control systems in our kilns to ensure every batch is fired within the exact window required to maximize pozzolanic activity. Every shipment is accompanied by a technical COA (Certificate of Analysis) to verify its reactivity.
Q: Are your kaolin products compliant with European REACH regulations? A: Yes. As an experienced exporter, all sjzhuabang functional minerals are fully compliant with REACH, RoHS, and international safety standards. We provide full documentation to ensure smooth customs clearance in all target markets.
