Software copyright description: The system integrates centrifugal separation and multi-stage microvia filtration technologies to dynamically recover residual coating liquids after spray coating or dip coating processes while performing closed-loop viscosity regulation. Through online solvent compensation and impurity separation (particles ≤5μm), the system enables coating liquid recycling and reuse. It is suitable for conformal coating and selective spraying production lines, reducing material consumption and VOC emissions while ensuring coating thickness consistency and insulation protection performance.
