Treatment of Electroplating Wastewater of Vacuum Electroplating Electric Heating Tube

Treatment of Electroplating Wastewater of Vacuum Electroplating Electric Heating Tube

The treatment of electroplating wastewater has received widespread attention at home and abroad, and a variety of treatment technologies have been developed to eliminate and reduce the discharge of heavy metals through measures such as transforming toxic to non-toxic, converting harmful to harmless, recycling precious metals, and recycling water. With the rapid development of the electroplating industry and the increasing environmental protection requirements, at present, the treatment of electroplating wastewater has begun to enter the stage of cleaner production process, total control and circular economy integration. Resource recycling and closed-circuit circulation are the mainstream directions of development.

Composition of electroplating wastewater for vacuum electroplating electric heating tube

The composition of electroplating wastewater is very complex. Except for cyanide-containing (CN-) wastewater and acid-base wastewater, heavy metal wastewater is a potentially harmful category of wastewater in the electroplating industry. According to the classification of heavy metal elements contained in heavy metal wastewater, it can generally be divided into chromium (Cr) wastewater, nickel (Ni) wastewater, cadmium (Cd) wastewater, copper (Cu) wastewater, zinc (Zn) wastewater, Gold (Au) wastewater, silver (Ag) wastewater, etc.

The difference between the process flow of vacuum electroplating electric heating tube

The process of Songgang plastic electroplating is: degreasing--hydrophilic--roughening--neutralization--pre-dipping--activation--degumming--chemical nickel--copper copper--acid copper--nickel-- chromium;

The process of metal electroplating is: cleaning -- electroplating copper sulfate -- electroplating semi-gloss nickel -- electroplating full-gloss nickel -- electroplating chromium -- drying;

The difference in the price of vacuum electroplating electric heating tubes

In terms of price: it depends on the material of the floor coating you use, as well as the coating thickness requirements and test requirements. Many factors will affect the price of electroplating. For example, if you want to chrome-plated a plastic part with a small surface area, it is cheaper. , Gold plating a relatively large metal part is more expensive, and the thickness of the coating directly affects the price. Therefore, to analyze the problem according to the actual situation, the two are not comparable. However, if it is the same coating, Songgang plastic electroplating is more expensive, because the plastic electroplating process is a few more steps, and it is not easy to coat, the difficulty is relatively large, and the cost is naturally high.
