I Electroplating equipment

In the electroplating process, the surface condition and processing requirements, select the appropriate steps, and carry out necessary trimming processing on the workpiece surface to make the workpiece surface smooth and clean, which is an important link to obtain high-quality coating. In the pretreatment process of plating, the main equipment used are polishing machine, grinder, sandblasting machine, polishing machine and various fixed grooves. In the whole production process, electroplating is the main process. According to the needs of the workpiece, select one or more single metal or alloy electroplating processes to conduct electroplating or immersion treatment on the workpiece to achieve the purpose of corrosion prevention, wear resistance and beauty. The equipment used for electroplating treatment mainly includes various fixed tanks, barrel plating tanks, hangers, baskets, etc. Post coating treatment refers to the processes of polishing, polishing, passivation, coloring, drying, sealing, dehydrogenation, etc. for the workpiece, and the appropriate process shall be selected according to the needs to make the workpiece meet the quality requirements. Commonly used post plating treatment equipment mainly includes grinder, polishing machine, various fixed grooves, etc.

2、 Principle of electroplating equipment

Electroplating equipment Ultrasonic cleaning equipment and electroplating equipment are integrated with R&D, design, manufacturing, sales and service. Electroplating is an electrochemical process as well as an oxidation-reduction process. The basic process of electroplating is to immerse parts in metal salt solution to make them become cathodes, use metal plates as anodes, and deposit the required coatings on parts after connecting to the DC power supply. Not all metal ions can be deposited from aqueous solution. If the side reaction of reducing hydrogen ions to hydrogen on the cathode is dominant, it is difficult to precipitate metal ions on the cathode. According to the experiment, the possibility of electrodeposition of metal ions from aqueous solution can get some rules from the periodic table of elements.

Anodes are divided into soluble anodes and insoluble anodes. Most of the anodes correspond to the soluble anodes of the coating, such as zinc anode for zinc plating, silver anode for silver plating, and tin lead alloy anode for tin lead alloy plating, For acid gold plating, platinum or titanium anodes are mostly used. The main salt ions in the plating solution are supplemented by adding the prepared standard gold containing solution. Pure lead, lead tin alloy, lead antimony alloy and other insoluble anodes are used for chromium plating.

3、 Advantages of electroplating equipment

① It has good economic benefits and can recover the initial expenses within 1~3 years. ② 75% - 90% of the circuit board wastewater from the electroplating plant is recovered. ③ The recovered water quality is stable below 200us/cm. ④ It can reduce the cost of wastewater recovery. ⑤ In restricted or water deficient industrial areas, such recovery devices can be used to ensure production. ⑥ The factory expands its production scale without increasing wastewater treatment equipment and discharge volume. ⑦ Full automatic continuous system is suitable for the reuse of large flow wastewater. ⑧ Regenerated water can be directly supplied to the assembly line or directly reused.
