Description
Technical field
The present invention relates to a kind of pretreating device, especially relate to a kind of online pretreating device, belong to the electroplating technology field at the Stainless Steel Wire copper coating.
Background technology
Along with expanding economy, industry power cord such as robot calculator, medical facilities, car electrics constantly develop to lightweight and filament direction, present power cord is made by fine copper usually, but because the shortage of China's copper resource and rising steadily of copper price, caused the power cord production cost too high, manufacturers press for the new metallic substance of searching and substitute original fine copper product.In recent years, occurred a kind of Copper Coated Stainless Steel Wire that can be used for substituting original fine copper product on the market, the cost of saving copper industry resource, reduction product has been played a good role.
During the Stainless Steel Wire electro-coppering, requiring must have good bonding force between copper layer and the Stainless Steel Wire matrix, therefore must guarantee that Stainless Steel Wire has fresh matrix through pre-treatment when plating tank enters the mouth.The main process of traditional online pretreating device is: Stainless Steel Wire is online pass the electrolytic pickling groove after, after washing, directly enter the alkaline electro plating bath and carry out electro-coppering.
Mainly there is following shortcoming in this pretreating device:
1, the washing bath water content consumption is big and the washing effect is undesirable, and the Stainless Steel Wire surface still is attached with residual acid, and is bigger to the influence of the basic plating solution pH value in the plating tank, coating instability and thinner thickness.
2, Stainless Steel Wire obtains fresh matrix after electrolytic pickling, and dry up again can be oxidized in the process through washing pressurized air, causes the bonding force of last copper plate and stainless steel base poor, comes off easily when being subjected to extraneous stress.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of Copper Coated Stainless Steel Wire online pretreating device, can obtain the thicker copper plate of thickness, and effectively improve the stability of coating and the bonding force of coating and matrix, the water content consumption of washing bath is also less simultaneously.
The object of the present invention is achieved like this: the online pretreating device of a kind of Copper Coated Stainless Steel Wire, described device is arranged at before the plating tank, it comprises pickling tank and washing bath, be characterized in: described device also comprises sealed vessel, described sealed vessel one end is connected with the outlet of washing bath Stainless Steel Wire, the other end stretches into plating tank and electroplates the liquid level below, also be provided with the air outlet on the sealed vessel, the air outlet is positioned at described plating liquid level top, described washing bath top seal, and its top also is provided with inlet mouth.
Described washing bath top is provided with several mouth sprays, the bottom is separated into several staircase areas from A-P, wherein first area liquid level is minimum, last area liquid level is the highest, each zone is provided with a mouth spray, and described several mouth sprays lay respectively at the top of described several staircase areas, and described first regional top is provided with overflow port, the bottom is provided with water outlet, and described last regional top is provided with water-in.
Compared with prior art, the invention has the beneficial effects as follows:
The online pretreating device of a kind of Copper Coated Stainless Steel Wire of the present invention, it comprises pickling tank, washing bath and sealed vessel, wherein be full of reducing gas in washing bath and the sealed vessel, prevented that effectively Stainless Steel Wire matrix fresh after the pickling is oxidized before entering electroplating solution, improved the bonding force of coating and matrix, and washing bath is divided into several staircase areas, divide some roads to clean, the rinse water in back road can overflow to preceding road and carry out recycle, the water yield that washing bath consumes is less and the washing effect is better, the residual acid of Stainless Steel Wire surface attachment seldom, pH value to electroplating solution does not have influence substantially, helps obtaining the thicker and stable coating of thickness.
Description of drawings
Fig. 1 is the structural representation of the online pretreating device of Copper Coated Stainless Steel Wire of the present invention.
Wherein:
Pickling tank 1, washing bath 2, sealed vessel 3, plating tank 4, inlet mouth 5, air outlet 6, mouth spray 7, water-in 8, overflow port 9, water outlet 10, guide wheel 11, cathode bar 12, dividing plate 13.
Embodiment
Referring to Fig. 1, the present invention relates to the online pretreating device of a kind of Copper Coated Stainless Steel Wire, described device is arranged at before the plating tank 4, it comprises pickling tank 1, washing bath 2 and sealed vessel 3, washing bath 2 top seals, and its top is provided with the inlet mouth 5 that is used for injecting reducing gas in washing bath, washing bath 2 tops are provided with several mouth sprays 7, the bottom is separated into several staircase areas from A-P by dividing plate 13, wherein first area liquid level is minimum, last area liquid level is the highest, described mouth spray 7 quantity equate with described staircase areas quantity, described several mouth sprays 7 lay respectively at the top of some staircase areas, described first regional top is provided with overflow port 9, the bottom is provided with water outlet 10, described last regional top is provided with water-in 8, described sealed vessel 3 one ends are connected with the outlet of washing bath 2 Stainless Steel Wires, the other end stretches into plating tank 4 and electroplates the liquid level below, sealed vessel 3 is provided with the air outlet 6 of reducing gas, and air outlet 6 is positioned at described plating liquid level top.
Principle of work:
Stainless Steel Wire obtains fresh matrix after electrolytic pickling, enter then in the sealing washing bath 2 that is full of reducing gas, after some roads washing of some staircase areas, enter again in the sealed vessel 3 that is full of reducing gas outside the washing bath 2, enter via guide wheel 11 and cathode bar 12 Stainless Steel Wires at last and begin copper facing in the electroplating solution, because all be full of reducing gas in washing bath 2 and the encloses container 3, can prevent effectively that Stainless Steel Wire matrix fresh after the pickling is oxidized, improved the bonding force of coating and matrix, each staircase areas all disposes a lift pump and is used for the water in the zone is extracted into mouth spray 7 cleaning Stainless Steel Wires, residual acid in the staircase areas reduces gradually from A-P, can enter front region after the rinse water overflow in the back region and carry out recycle, through the surperficial basic noresidue acid of washing back, some roads Stainless Steel Wire from A-P, the washing effect is better and water content consumption is less.
