This process-level approach ensures consistency in product appearance and performance.
3.2 Post-Treatment and Refining Process
Following polymerization, the product undergoes multiple refining stages—including solvent removal, screening, dedusting, and drying—to eliminate fine fragments and substandard particles. This standardizes particle size and bulk density, ensuring high consistency across batches regarding particle flowability, solubility, and charge density, thereby preventing issues related to inconsistent appearance or performance fluctuations.
3.3 End-to-End Closed-Loop Quality Control System
Raw materials undergo incoming inspection for monomer purity and moisture content. During polymerization, molecular weight, charge density, and particle formation are monitored in real-time. Finished products are tested batch-by-batch for solid content, bulk density, dissolution rate, pH compatibility, chlorine resistance, and thermal stability; comprehensive quality inspection reports are issued for every batch to strictly ensure product quality before shipment.
