Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of can substrate surface do simultaneously chromium plating and water transfer surface process processing method.
The technical solution adopted in the present invention is: the processing method of a kind of chromium plating and water transfer compound base amount method, comprises the following steps:
1) polish at substrate surface, wire drawing and/or polished finish;
2) insulating protection is done at non-chromium plating position;
3) chromium plating process is carried out;
4) after chromium plating has processed, remove the insulating protection at non-chromium plating position, and do the transfer protection of non-water at chromium plating position;
5) water transfer process is carried out;
6) water transfer process removes water transfer protection after completing, and completes the finishing of edge, seam place.
Specifically, the base material in step 1) of the present invention comprises iron part, zinc alloy or stainless steel.
Step 2 of the present invention) in, the insulating protection method at non-chromium plating position comprises: adopt adhesive tape sticking be evenly coated at non-chromium plating position, with wax liquid non-chromium plating position, with conductive resin or only plating paint be coated in non-chromium plating position; In described step 4), the position doing the transfer protection of non-water is the boundary place with water transfer process for chromium plating position; Described non-water transfer protection adopts high temperature gummed tape to paste the edge at chromium plating position.
The invention has the beneficial effects as follows: chromium plating and water transfer two kinds of surface treatment modes and deposits, meet different superficial makings requirements, color clarification, be the space that the selection offer of various superficial makings is more wide.
Embodiment
The present invention is further detailed explanation in conjunction with the embodiments now.
Example 1
A processing method for chromium plating and water transfer compound base amount method, comprises the steps:
1) polish at substrate surface, wire drawing or polished finish;
2) with high temperature resistant, the adhesive tape of resistance to peracid, is bonded in the position of non-chromium plating;
3) chromium plating process;
4) anti-retaining tape is removed;
5) position of non-water transfer it is bonded in high temperature gummed tape;
6) water transfer process;
7) high temperature gummed tape is removed;
8) edge, seam place finishing.
Example 2
1) polish at substrate surface, wire drawing or polished finish;
2) position of the non-chromium plating of product it is coated in uniformly with wax liquid;
3) chromium plating process;
4) wax layer is removed;
5) position of non-water transfer it is bonded in high temperature gummed tape;
6) water transfer process;
7) high temperature gummed tape is removed;
8) edge, seam place finishing.
As the Some substitute scheme of above-mentioned example approach, non-chromium plating face insulating protection can also adopt painting conductive resin, is coated with the method for only plating paint insulation.
As the preferred version of above-mentioned example approach, described non-chromium plating face insulating protection adopts adhesive tape insulation method.
As the preferred version of above-mentioned example approach, described non-water transfer place protection adopts high temperature gummed tape.
Wherein, the chrome-plated process method of different base materials is as follows:
1, iron part chrome-plated process flow process:
Except wax �� hot dipping oil removing �� negative electrode �� anode �� electrolytic degreasing �� mild acid etching �� preplating alkali copper �� acidity bright copper (selection) �� bright nickel �� chromium plating or other
Except wax �� hot dipping oil removing �� negative electrode �� anode �� electrolytic degreasing �� mild acid etching �� semi-bright nickel �� high sulphur nickel �� bright nickel �� nickel envelope (selection) �� chromium plating
2, zinc alloy chrome-plated process flow process
Except wax �� hot dipping oil removing �� catholyte oil removing �� pickling �� alkalescence bright copper �� cupric pyrophosphate (selectivity) �� acidity bright copper (selectivity) �� bright nickel �� chromium plating
3, stainless steel direct plating chromium process
1) electrochemical degreasing �� hot water wash �� cold water washes �� pickling activation (1ml/LHCL, 10ml/LH2SO4, room temperature, half a minute; It is applicable on automation line stainless steel chromium plating, unsuitable copper facing or nickel) �� washing �� chromium plating.
2) electrochemical cathode oil removing �� cleaning �� anode activation (10A/dm2) �� directly chromium plating.
3) electrochemical deoiling �� cleaning �� anode electrochemical oil removing (0.5A/dm2) �� cleaning �� pickling activation (1ml/LHCL, 10ml/LH2SO4, room temperature, 45S) and �� cleaning �� chromium plating
The water transfer printing technique method of the present invention is:
1) tap water is injected in tank;
2) being attached on the water surface by water transfer printing film, spray the water transfer printing film on the water surface with promoting agent gently, after water transfer printing film resolves into particulate, leave standstill about one minute, water temperature is at about 30 DEG C;
3) product being put into tank gently, due to electrostatic adsorption, the pattern particulate of water transfer printing film is adsorbed on product surface;
4) product is removed, rinse with clear water, the particulate remaining in product surface is cleaned clean;
5) product of printed pattern is placed in 60 DEG C of baking ovens 1 hour, solidification.
6) by product surface spray coating finishing paint, to be solidified.
The just the specific embodiment of the present invention described in above specification sheets, the flesh and blood of the present invention is not construed as limiting by various illustration, person of an ordinary skill in the technical field after having read specification sheets can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of invention.
