Description
Technical field
The present invention provides a kind of room temperature ultrasonic electrolysis parkerizing method and device for before steel wire drawing, belongs to phosphatization
Technical field.
Background technology
Metal surface phosphating refers to being surface-treated to metal with phosphorization reagent, one layer uniform, thin in its Surface Creation
The process of close, wear-resisting, corrosion resistant phosphating coat.
It is mainly used for the alramenting of iron and steel parts in practical applications, but non-ferrous metal is as the workpiece such as aluminium, zinc also can be into
Row phosphorating treatment.
It carries out phosphorating treatment before steel wire drawing to be primarily due to, the phosphating coat that steel wire surface is formed can improve lubrication effect
Rate is generated under very high pressure condition all in metal surface as zinc phosphating film can react with stearate lubricant
It is the zinc stearate of fabulous lubriation material, drawing speed can be greatly improved, extend die life, improves finished product rate.
There is many defects for traditional phosphating process：
1, traditional most of phosphating process needs to carry out at a relatively high temperature, and the parkerized time also compares
It is long, the loss of the energy and the increase of sediment can be caused in this way；
2, traditional room temperature, low temperature phosphor processing need that some other accelerating agents such as oxidant, neutralizer etc. are added to accelerate into
Film speed improves phosphorization film quality in turn, therefore a series of side reaction can be caused to occur, and keeps film forming procedure complicated and makes phosphatization
Liquid generates a large amount of precipitations；
3, traditional phosphating process often will produce environmentally harmful substance in process of production, to working for a long time in the occasion
The life security of worker there is huge threats.
Room temperature electrolytic phosphating process reaction speed is fast, low energy consumption, but the phosphating coat Film Thickness Ratio high temperature chemistry phosphatization formed
Phosphating coat want thin, the steel wire than high temperature chemistry phosphatization is more easy to occur fracture of wire and overproof during the drawing process.
Invention content
The object of the present invention is to provide a kind of working environment that can be overcome drawbacks described above, worker can be improved, at normal temperatures
