Abstract
The invention discloses a method for reducing corrosion and oxidation blacking of a copper strip in the processing production process of a copper strip, which belongs to the technical field of copper strip casting. In the method, clean production guarantees good surface quality of the copper strip; air is kept dry during the transportation and the use of the copper strip; and the copper strip is prevented from being stored in dust, cigarette ash, high-temperature and sulfur dioxide (SO2) environments. Due to the clean production and the controlled state of production, transportation and storage links, the problems of discoloring and blacking of the copper strip are mostly solved.
Description
Technical field
The present invention relates to reduce in a kind of copper strips processing process the method for copper strip corrosion, oxidation blackout, belong to copper strips casting processing technical field.
Background technology
Only paid attention to surface treatment in the copper strips processing process; particularly carry out Passivation Treatment; wrapping material in the packing of product such as building paper, plastic cloth, siccative etc. are protected; prevent that band from producing the oxidation blackout; the oxidation stain phenomenon takes place but the copper strips finished product is left, and it has become the problem that copper processing enterprise is difficult to solve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the method that reduces copper strip corrosion, oxidation blackout in a kind of copper strips processing process, the difficult problem that this method can significantly reduce the copper strips oxidation stain occurs.
Technical scheme of the present invention is: reduce the method for copper strip corrosion, oxidation blackout in a kind of copper strips processing process, it is characterized in that, cleaner production guarantees that copper strip surface quality is in shape.
Know-why of the present invention is: at first require copper strip surface quality must be smooth clean, otherwise because defectives such as surface irregularity, load mould, peeling, folder brightness have caused residue may produce microbattery when environmental change, appearance potential difference and corrosion phenomenon takes place.Copper strip surface quality is main relevant with surfaceness, hardness, technological lubrication, pickling and the annealing of roll, its major defect is that pickling does not thoroughly produce oxidation, because cleaning was unclean after oil mark was crossed reannealing, copper strips long and furnace annealing surperficial copper strips variable color, the spot of causing of poor quality storage period.The scratch of copper strip surface, scuffing load mould etc. also can cause the decline of zone face quality.The quality of copper strip surface quality is the root that produces the corrosion oxidation variable color in sum, and carrying out cleaner production is to prevent that these defectives from producing one of most important method.
Described cleaner production is specially:
(1) copper strips job shop all devices carries out big fill weekly one time, and regular key position and pipeline to equipment carried out the big fill inspection in every month, guaranteed the cleaning of equipment; Molding floor's dust falls into copper water and can cause the folder brightness simultaneously, should adopt strict technology, guarantees ingot casting casting volume surface and internal soundness;
(2) be optimized producing technical indicators such as medium such as emulsion, ROLLING OIL, grease-removing agent, passivating solution, water for cleaning, the water for cleaning specific conductivity is controlled at below the 50 μ s/cm, and to medium checks every day such as grease-removing agent, passivating solutions once, guarantee that mass of medium meets the requirements;
(3) at the surface-treated key post, as: equipment such as pickling line, stretch bending-straightening machine, finished product slitter add dw, and workshop hygiene is cleaned constantly, guarantee good working environment, guarantee that the copper strip surface light is clean;
(4) guarantee that the roll light is rustless, do not have roll marks, twill, spiricle etc. to guarantee strip surface;
(5) the strict technology of carrying out: residual acid or the residual moisture of removing copper strip surface, prevent that cold rolling back from surpassing one day and annealing and corrode, each cleans and cooling water matter wants clean, and specific conductivity is controlled at below the 50 μ s/cm, and the deionized water specific conductivity should be controlled at below the 2 μ s/cm; Grease-removing agent adopts P3-T7221, and concentration is 0.3-0.5%, 70 ℃ of working temperatures; Passivating solution adopts BTA, and concentration is 0.2-0.5%, and bake out temperature is 80 ℃ after the passivation, and outlet postcooling chamber is cooled to below 40 ℃ batches;
(6) packing: finished product prevents to scratch, abrade, damage when shearing, and the contact copper strips will be packed with clean gloves, adopts packings such as building paper, plastics bag, siccative to tie up solid.
Except that the work of carrying out above every cleaner production, also require when storing transportation and using, to note atmospheric environment, particularly southern damp atmosphere is easy to cause electrochemical reaction, except that our Package Quality will be got well, transportation must not be intake, the warehouse, south is must not be too moist in order to avoid produce electrode reaction, therefore will keep copper strips to store transportation and dry air when using, and galvanic principles is Cu → Cu

3And form weak acid and reduced the copper strips critical humidity and be corroded, so copper strips should be avoided being placed in this environment, be exactly that copper strips not easy to store under the environment such as dust, cigarette ash and high temperature is arranged in the air in addition; Be based on doing well cleaner production in a word, keep producing, transport, store each link and be in controlled circumstances, copper strips variable color blackout just can most ofly solve, and copper strips oxidation stain blackout phenomenon greatly reduces after we implement cleaner production.
The invention has the beneficial effects as follows: adhere to cleaner production strengthened production process discipline, carry out the every work of production, accumulating of product, the difficult problem that can significantly reduce the copper strips oxidation stain occurs, and wherein cleaner production is vital.Just implement in cleaner production the previous year to return goods greatly 160 tons producing in 3-5 month, after implementing this invention Cleaning production measures, obtain positive effect because of oxidation stain, because of the oxidation stain return of goods have only 30 surplus ton.
