Description
Technical field
The invention belongs to chemical industry field of electroplating, and in particular to a kind of electrochemical treatments liquid and its application, especially electrochemistry
Handle the electrochemical treatments liquid of the workpiece of laser engraving.
Background technique
Laser engraving is the processing technology using laser as process medium, rapidoprint under laser irradiation the fusing of moment and
The physical modification of gasification can make laser engraving achieve the purpose that processing.The characteristics of laser processing, is not contacted with material surface,
It is not influenced by mechanical movement.
In electroplating industry, rapid laser carving burns workpiece surface layers of copper and white oil with the high temperature that laser generates.Laser
Engraving can form very thick oxide layer on copper surface, when with common phosphoric acid treatment fluid, cannot guarantee the indeformable situation in site
Under completely remove thick oxide layer.In addition, either high current density still extends when being handled with common phosphoric acid polishing fluid
The processing time can all cause the destruction of lattice point structure, not only result in workpiece surface nigrescence, and be highly detrimental to subsequent electricity
Plate process.
Electrochemical treatments are also known as electrochemical polish or electrobrightening, are the workpiece to be polished as anode, insoluble petal
For cathode, the two poles of the earth are immersed in electrolytic cell simultaneously, direct current is passed to and generates selective anodic solution, to reach increasing
The effect of work piece surface brightness.When carrying out electrochemical treatments to the workpiece of laser engraving, need selectively to dissolve work
The oxide layer that part surface is formed selects suitable electrochemical treatments liquid most important without influencing workpiece body.It is existing
Electrochemical treatments liquid is mainly made of phosphoric acid, glycerol, thiocarbamide etc., and treated, and workpiece mainly has the disadvantage that: (1) workpiece is in height
After electric current, long time treatment, workpiece surface temperature is steeply risen, workpiece surface rapid oxidation, is unfavorable for observing dot shape
Variation；(2) after electrochemical treatments, workpiece surface forms one layer of very thick tunica albuginea (additive decomposition product residual), after being unfavorable for
Continuous process reprocessing；(3) workpiece easily corrodes after long time treatment；(4) change at the top of site after the removal of site bottom oxidization layer
Shape is serious.
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of electrochemical treatments liquid, are used for electrochemical treatments
The workpiece of laser engraving.When handling the workpiece of laser engraving with electrochemical treatments liquid of the invention, workpiece surface not will cause
Oxidation and corrosion, can completely remove site bottom oxidization layer in the case where guaranteeing the indeformable situation in site, increase workpiece surface
Brightness, and then meet the needs of subsequent handling.
The present invention is achieved by the following technical solutions:
A kind of electrochemical treatments liquid, including following component according to parts by weight:
A kind of electrochemical treatments liquid, including following component according to parts by weight:
A kind of electrochemical treatments liquid, including following component according to parts by weight:
Preferably, the density of the sulfuric acid is 1.84g/cm3, the density of the phosphoric acid is 1.71g/cm3。
Preferably, the brightener is sulfosalicylic acid.
The application of above-mentioned electrochemical treatments liquid, the electrochemical treatments liquid are used for the workpiece of electrochemical treatments laser engraving.
Beneficial effects of the present invention:
(1) with the workpiece of electrochemical treatments liquid processing laser engraving of the invention when, the oxygen formed on workpiece can be removed
Change layer, and not will cause the re-oxidation of workpiece；
(2) with the workpiece of electrochemical treatments liquid processing laser engraving of the invention when, workpiece body is not influenced, guarantees workpiece
Stipple pattern structure it is indeformable；
(3) with the workpiece of electrochemical treatments liquid processing laser engraving of the invention when, the light of workpiece surface can be increased
Degree, and then meet the needs of subsequent handling.
Detailed description of the invention
Fig. 1 is the picture with electrochemical treatments liquid of the invention to site after the workpiece electrochemical polish of laser engraving；
Fig. 2 is the picture for carrying out site after electrochemical polish to the workpiece of laser engraving with common electrochemical treatments liquid.

Test example
With in 1-5 of the embodiment of the present invention electrochemical treatments liquid and common electrochemical treatments liquid to laser engraving after
Workpiece carries out electrochemical treatments, the specific process is as follows: clean workpiece oil stain (room temperature oil removing) with degreaser carries out electrochemistry afterwards
Polishing.The parameter of electrochemical polish are as follows:
Polishing time: 5-30min；
Polishing fluid temperature: 25 DEG C；
Polish current density: 40A/dm2；
Electrochemical treatments mode: roller circumferentially rotates；
Roller revolving speed: 24mm/s
Cathode, anode distance: 50mm
Cathode material: 304 stainless steel plates
Anode material: the coppersmith part after laser engraving
Immersion way: half immersion.
With electrochemical treatments liquid of the invention to the coppersmith part electrochemical polish of laser engraving it can be seen from attached Fig. 1 and 2
Workpiece blacks afterwards, this is because without destroying network structure in electrochemical treatment process；And with common electrochemical treatments liquid pair
Workpiece whitens after the coppersmith part chemical polishing of laser engraving, this is because destroying network structure in electrochemical treatment process.?
In actual production process, the higher market response of the blackness of workpiece is better after electrochemical polish.
