Description
Technical field
The present invention relates to a kind of circulation molten copper liquid making device and method for rolled copper foil copper facing operation.
Background technology
Calendered surface processes Copper Foil and has excellent tensile strength, good elongation percentage and surface low profile degree, and the good physical behavior such as the metal densification of excellence and low-resistivity.The advantage of these uniquenesses so that calendered surface processes Copper Foil and holds big lead over generally at electronics manufacturing area the most widely used electrolytic surface process Copper Foil.It can be seen that calendered surface processes Copper Foil has more powerful quality-advantage and bigger development space than electrolytic surface process Copper Foil.Rolled copper foil process for treating surface theoretical research and production, be the domestic important new industry in recent years risen.This respect, China, on the basis of developing voluntarily, developing, achieves many achievements.Also introduced a new research and production technology and the relevant device abroad with Advanced Idea simultaneously.But, at present, domestic and international calendered surface processes the production technology and eqUipment of Copper Foil, the most generally has the general character of some shortcomings, tediously long especially in the presence of complex process, quality is fluctuated and cost, energy consumption remain high, process equipment needs improvement etc. problem.At present, the solution that these problems have not also had.
The circulation molten copper liquid making mode of traditional rolled copper foil copper facing operation mainly uses systemic circulation liquid making technology pattern (see accompanying drawing 1).Systemic circulation molten copper liquid making technology pattern, is that the circulation liquid making of molten copper system is series circulation with whole solution recycle system.It is that circulation liquid making technology pattern " is led directly to " in the molten copper liquid making of circulation limit, a kind of limit.The advantage of this technology pattern is that process equipment is simple, and molten copper is fast, easy to operate.Shortcoming is when circulating liquid making (instant copper process), and its process circulating molten copper must be continuous print, that is, as long as molten copper process is carried out in systemic circulation, the process of molten copper will be carried out simultaneously.This may result in production, when whole copper plating solution need not increase copper content, circulates molten copper process and is still carrying out.This to producing and the control of technique, is totally unfavorable to this phenomenon.Thus, the molten copper speed controlling of the technology pattern of this circulation liquid making is very difficult.Some low copper solution in processing especially for surface, this circulation liquid making technique, it is easy to make the copper content of solution during the molten copper of continual systemic circulation, beyond the upper limit of technological parameter, make the controllability of process conditions reduce.

Copper plating solution is as follows with reference to technological standards:
(1) solidification copper facing
Copper facing: Cu:30～80g/L；H2S04:60～160g/L；
Molten copper: Cu:50～150g/L；H2S04:60～160g/L；

In the technical process of the present invention, in the case of the just start of rolled copper foil surface treating machine row or being badly in need of supplementation with copper ion, use the molten copper molten copper pattern of tower systemic circulation, make solution copper content be rapidly reached process goal value.After entering normal production, use the molten copper molten copper pattern of tower partial circulating, use the mode of systemic circulation set partial circulating, make copper plating solution system maintain the needs of normal supplementation with copper ion.Such novelty, flexible copper pattern, the input of required increase is the least.
Can be seen that, use novel, circulate molten copper pattern flexibly, the advantage that can take into account different molten copper circulation pattern, when driving or needing quick supplementation with copper ion, the feed liquor of molten copper tower is entered by machine row electroplating bath overflow, now for using systemic circulation molten copper liquid making pattern, add molten copper tower and self molten copper of molten copper circulating slot cooperation so that whole solution system cupric is timely, be rapidly reached technic index.When normally producing, systemic circulation can be used to overlap partial circulating molten copper liquid making pattern, now, the feed liquor of molten copper tower is the clearance-type molten copper liquid making of self molten copper circulation.Therefore, alternately use two kinds of copper pattern the most molten, suitably can select in terms of molten copper speed and stability.Simultaneously as can reasonably use the molten copper of batch (-type) in producing at ordinary times, the copper content not only making solution system is more stable, also can obtain the effect of control, energy efficient simultaneously.
The technique of patent of the present invention and equipment feature compared with the existing technology, have a beneficial effect highlighted below:
1) owing to have employed the molten copper liquid making pattern of novel circulation, the big flow of systemic circulation can be used to circulate copper copper liquid making mode, when (fluting) starts shooting or needs make-up solution copper content rapidly, save time and the time of adjusting process condition of fluting (start).As: the molten copper of circulation liquid making of first start, the citing of molten copper is solidified with typical, use systemic circulation big flow circulation copper copper liquid making mode, molten copper speed is up to 15kg/Hr, and the copper of consumption per hour that surface treatment copper foil normally produces is: 1.186g/A/Hr (electrochemical equivalent) × 4500A (maximum) × 1 hour (time) × 95% (current efficiency)=5230.26g=5.23kg i.e.: the normal consumption copper speed that produces is: 5.23kg/Hr.
As can be seen here, use systemic circulation big flow circulation copper copper liquid making mode, per hour can molten copper 15kg, be much higher than the consumption copper speed of production, its molten copper ability has the biggest surplus.The circulation molten copper mode of the big flow of this systemic circulation, for first molten copper and the quick supplementation with copper ion of slotting, is very useful.
2) when normally producing, being switched by conversion valve and associated appliance, use the molten copper pattern of clearance-type partial circulating, more continuous systemic circulation molten copper liquid making pattern substantially reduces energy resource consumption.And it is a major advantage that, the copper ion that this pattern is supplemented is not direct, but indirectly toward the pattern of supplementation with copper ion, decreases copper ion concentration because of the anxiety exceeded standard increased rapidly.
3) use above novel, circulate molten copper liquid making pattern flexibly:
(1) can save and slot time for the first time
(2), when normally producing, clearance-type can be utilized to use dosing pump and the circulating pump of low discharge, replace the circulating pump of big flow, save energy resource consumption to a certain extent.
(3) owing to have employed above-mentioned circulation liquid making pattern, the most about improve production efficiency 3%, economic benefit is obvious.
In sum, patent of the present invention is because having the various features such as simple, novel, energy-conservation, efficient, thus has good application value.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that: these embodiments can carry out in the case of without departing from the principle of the present invention and objective multiple change, revise, replace and modification, the scope of the present invention is limited by claim and equivalent thereof.
