5）, by step 4）Abnormal workpieces after middle deacidification enter inside barrel plating tank, right in the case where the rotation stirring of rotating plating cylinder is rotated
Abnormal workpieces carry out electrogalvanizing operation, it is zinc-plated after abnormal workpieces enter washing pool carry out second adverse current flushing；
6）, to step 5）Abnormal workpieces after middle flushing enter passivation pool, and the main component of passivator is passivator, nitric acid；
7）, to step 6）Abnormal workpieces after middle passivation again pass by soak vat progress water logging and washed, and eventually pass natural drying, complete
Into Product checking, qualified zincate rolling galvanized workpiece is produced.
It is preferred that, the step 4）In, using the rotating speed for controlling frequency converter to change AC driven motor, so as to control barrel plating
The rotating speed of system, reduction rotating speed makes electroplating current sufficiently utilize, while the rotating speed for plating roller can be according to different workpiece requirements
Any adjustment.
It is preferred that, the step 3）In, using controlling frequency converter to change after rotating speed, make traditional rotating plating cylinder rotating speed by every
12 turns of minute, 3 turns per minute are reduced to, so that the phase mutual friction between reducing workpiece, the phenomenon damaged.
It is preferred that, the step 6）In, make driving alternating current generator positive and negative in defined time interior circulation using circuit is controlled
Turn, make the iron wire workpiece of complexity during barrel plating, it is to avoid mutually winding, cause deformation, reduce between workpiece and conductive cable
Winding, the usage cycles of conductive cable are improved, while according to the complexity of workpiece outward appearance can also be set the rotating time.
Compared with prior art, the beneficial effects of the invention are as follows：
The zincate barrel plating zinc technology project has researched and developed success, is verified through produced on-site, using solving barrel plating work after this technique
The problem on deformation of part, the phenomenon of plating leakage extends the usage cycles of negative electrode conductive cable.Product quality is substantially improved, is public
Department has saved substantial amounts of production material, creates fair margin of profit.
