Description
Technical field
A kind of effective continuous copper-plating of steel strip technique of Bandaid, is specifically related to the technical field of continuous steel strip electroplating.
Background technique
What Bundy tube was mainly manufactured by steel band copper facing, it is commonly utilized in automobile oil pipe, floor heating pipe, air-conditioner pipe etc.
Aspect.Available fine and close, smooth, the good coating of binding force of cyanide electroplating, so continuous copper-plating of steel strip uses cyanide electroplating
Technique, although the clearly superseded cyanidation technology of country, the technique for not finding substitution till now, and because it is widely used in essence
The fields such as close electronic instrument, precision instrument, aerospace can only delay to eliminate.
Summary of the invention
According to documents, steel band can take plating solution out of during entering next coating bath from a coating bath, and be dropped in
Outside coating bath, the waste of plating solution will cause in this way, since plating solution is toxic, also will cause pollution, be unfavorable for clean manufacturing.Steel band simultaneously
Surface can adhere to all kinds of impurity and dirt, if all kinds of impurity and dirt are brought into next process and can pollute plating solution and influence to plate
Layer quality, it will lead to the appearance of substandard product.Water in the content of present invention, during copper facing, after atomizing spray cleaning
Female groove is flowed into using vacancy slot and the high potential difference of female groove, and plating solution is transmitted back to coating bath using filter pump；Plating solution waste water passed through
Filter pump enters closed processes slot, and treated plating solution is transmitted back to female groove by filter pump, and female groove conveys plating solution by filter pump
To copper plating groove, the online processing and recycling of sodium carbonate are realized.Plating solution when encountering the emergency cases such as power failure, in copper plating groove
The storage of closed processes slot is flowed by female groove under gravity, it is therefore prevented that the waste of plating solution.Conductive rollers spray clear
Wash, and ejected wash water be recycled, the liquid in female groove is plating solution in a saturated state, if lack it is a certain from
Son can be added in closed processes slot, is transported in female groove, then be transmitted back to coating bath by filter pump, at the same steel band be it is S-type walk
To saving production line cost about half.
