The electroplating filter machine is a critical piece of equipment used in industrial production to filter electroplating solutions, chemical liquids, and other corrosive fluids. Its primary function is to remove impurities and particles from the solution, ensuring high-quality plating, extending the life of the chemicals, and supporting environmental compliance. The following details the core functions, main types, and application scenarios of electroplating filter machines:
Enhance Plating Quality: Filters out suspended particles, metal ions, and other impurities from the solution to prevent issues like rough or uneven plating, and pinholes. For instance, in chemical galvanizing, it can effectively filter out hydroxide colloids to prevent darkening of the plating layer.
Extend Solution Lifespan: Reduces the frequency of solution replacement and lowers chemical consumption. For example, using activated carbon to adsorb organic matter can extend the service life of nickel plating solutions.
Support Environmental Compliance: Ensures that the treated liquid meets wastewater discharge standards. For example, bag filter machines can efficiently recover precious metal particles from the solution.
By Filter Material:
Cartridge Type: Includes wound filter cartridges (large dirt holding capacity), melt-blown filter cartridges (high precision, large flow), and activated carbon cartridges (combined filtration and adsorption functions).
Bag Type: Suitable for filtering high concentrations of particulate impurities, commonly used for coarse filtration in aluminum anodizing or phosphating processes.
Paper Type: Used for precision filtration (with precision up to 0.1 microns), commonly seen in PCB electroplating liquid treatment.
By Pump Type:
Magnetic Drive Pump: Features a seal-less design with zero leakage, ideal for applications sensitive to air bubbles, such as electrophoretic paint and pearl nickel treatment.
Self-Priming Pump: Strong self-priming ability, low cost, and commonly used for general electroplating solution transport.
Vertical Pump: Can withstand dry running and is capable of handling chemical nickel plating liquids that contain crystallized particles.
Electroplating Industry: Includes hardware electroplating (such as acid zinc or cyanide zinc solutions), plastic electroplating (to remove residual colloidal particles from pre-treatment), and precious metal electroplating (to ensure the gloss of the plating layer).
Surface Treatment: For example, PCB etching solution filtration to prevent copper particles from clogging nozzles, and filtration of acidic electrolyte in aluminum anodizing processes to avoid spot defects on the coating.
Environmental Protection and Resource Recovery: Used to treat electroplating wastewater to recover heavy metal ions, or for regenerating chemical solutions.
This equipment plays an essential role in improving the efficiency of electroplating processes, ensuring the longevity of solutions, and supporting sustainable production practices.
