Electroplating is an electrochemical process as well as an oxidation-reduction process. The basic process of electroplating is to dip the parts in the solution of metal salt as the cathode, and the metal plate as the anode. After the DC power supply is connected, the required coating is deposited on the parts.

Not all metal ions can be deposited from aqueous solution. If the side reaction of hydrogen ion reduction to hydrogen on the cathode is dominant, it is difficult for metal ions to precipitate on the cathode. According to the experiment, the possibility of electrodeposition of metal ions from aqueous solution can be obtained from the periodic table of elements.

Anodes are divided into soluble anodes and insoluble anodes. Most anodes are soluble anodes corresponding to the coating, such as zinc anode for zinc plating, silver anode for silver plating, and tin lead alloy anode for tin lead alloy plating. However, a few electroplating uses insoluble anode due to the difficulty of anode dissolution. For example, platinum or titanium anode is mostly used for acid gold plating. The main salt ions of the plating solution are supplemented by adding the prepared standard gold containing solution. Chromium plating anode uses insoluble anode such as pure lead, lead tin alloy and lead antimony alloy.

In electroplating operation, the temperature control is very strict, so Electroplating equipment In general, there will also be a complete problem control system. Now let's see what devices are included in this system? How to ensure the temperature required for electroplating?

The control of process temperature is the top priority in the electroplating process. If the temperature fluctuates greatly, it will directly affect the quality of electroplating and cause energy waste. The existing electroplating equipment has taken this into consideration when designing, and the pre heating function is set on its human-machine interface, through which the pre heating time can be set.

At the same time, the heating system of electroplating equipment is also equipped with liquid level control device, automatic water supplement device, etc., which can realize the function of automatic liquid level supplement of the system when the liquid level is lower than the set liquid level. So as to protect the system and prevent the heating pipe from dry burning or safety accidents. In addition, the use of PID fuzzy control is also to avoid adverse effects caused by temperature.
