Performance Characteristics Comparison
Industry Applications
🔧 Foundry Industry Applications
Hezhen bentonite serves as an exceptional binding agent in foundry applications. Its superior thermal stability (up to 1450°C), excellent plasticity, and high dry compression strength (≥0.8 MPa) make it ideal for green sand molding in ferrous and non-ferrous metal casting. Our binder bentonite reduces veining defects by up to 70% compared to conventional materials.
Case Study A major automotive parts manufacturer achieved 23% reduction in casting defects and 15% reduction in binder consumption after switching to Hezhen foundry-grade bentonite.
⛽ Oilfield Drilling Applications
As a premier drilling fluid additive, Hezhen Waterproof material bentonite provides critical functions: hole-cleaning efficiency enhancement (25-40% improvement), wellbore stabilization, lubrication, and filtration control. Our API-certified bentonite demonstrates remarkable yield (135+ bbl/ton) and reduces fluid loss by 45% compared to standard materials.
Technical Note At concentrations of 22-25 kg/m³, Hezhen bentonite achieves plastic viscosity of 18-22 cP and gel strength of 8-12 lb/100ft², optimizing hydraulic efficiency in directional drilling operations.
🐱 Cat Litter Applications
The superior clumping performance of Hezhen bentonite in cat litter formulations originates from its optimized particle size distribution (70-100 mesh) and sodium activation process. It delivers rapid clump formation (within 15 seconds), 99.9% odor control, and dust reduction of over 90% compared to conventional products.
Performance Data Laboratory tests show 1kg of Hezhen cat litter-grade bentonite absorbs approximately 380ml liquid while maintaining structural integrity for 72 hours.
