3. Manufacturing Process Flow & Technology Analysis
Critical Process Nodes:
Electrolysis: High-purity ammonium sulfate and sulfuric acid solution pass through titanium or platinum anode cells (per ASTM E973). Precision voltage controls crystal growth and minimizes byproducts.
Crystallization: The post-electrolysis solution is cooled in ISO 14644 clean rooms to yield uniform, easy-to-handle crystals, reducing inclusion defects.
Centrifugation & Washing: Automated, CNC-controlled centrifuges ensure residuals are virtually eliminated, meeting ANSI/NSF 60 requirements for trace metal and nitrate content.
Drying: Low-temperature, inert-gas dryers prevent decomposition and guarantee stable bulk density and particle size distribution. Batch sampling is performed per ISO 9001:2015.
Final QC: Each lot undergoes ICP-OES and HPLC testing for purity, homogeneity, decomposition parameters, and corrosion potential, following GB/T 19277 standards.
The entire process leverages materials such as acid-resistant titanium, stainless 316L process lines, and is monitored by a digital SCADA system, supporting superior traceability and eco-efficiency. Manufacturing meets or exceeds ISO 9001:2015 and ANSI/NSF 60 quality benchmarks.
