Introduction:
As the global ceramics sector faces intensified carbon neutrality mandates and resource scarcity, Green Substitution has evolved into a strategic imperative for operational continuity. At Sunlets, we are exploring how sustainable material science integrates with High-Pressure Casting (HPC) to deliver high-performance, low-impact sanitaryware.
1. Valorization of Industrial Waste
Repurposing by-products from other industries into high-grade ceramic inputs is the most viable path toward a circular economy.
Recycled Glass and Fly Ash: Finely milled recycled glass can effectively replace feldspar as a primary flux.
Technical Advantage: Incorporating 10%-15% recycled glass cullet into the body formulation can lower firing temperatures by 20°C-30°C, significantly reducing the energy-related carbon footprint.
Scraps generated during the High Pressure Casting Machine cycle are now 100% recyclable via Sunlets’ proprietary high-energy milling and homogenization processes.
2. Green Chemistry: The Revolution of Eco-Friendly Additives
Sustainable raw materials require compatible green chemical auxiliaries to maintain rheological performance.
Bio-based Deflocculants: The industry is pivoting from petroleum-based sodium polyacrylates to lignin-based sulfonates and plant-derived polysaccharides.
These bio-based agents do more than reduce chemical oxygen demand (COD) in wastewater; their non-crystalline nature prevents mineral buildup within High-Pressure Resin Molds, extending mold functional life by over 15%.
3. Functional Mineral Substitution and Low-Carbon Formulations
Tailings Utilization: High-purity tailings enriched in lithium and potassium can replace scarce natural feldspar, reducing raw material procurement costs by approximately 12% while maintaining identical thermal expansion coefficients.
Digital Formulation Compensation: To manage the inherent variability of alternative materials, Sunlets utilizes digital platform that dynamically adjusts the Deflocculant dosage, ensuring consistent yield rates regardless of raw material shifts.
