Abstract
The utility model belongs to the technical field of electrolytic copper foil equipment and particularly discloses a conductive roller. The conductive roller comprises a stainless steel roller body, wherein the outer surface of the roller body is sequentially provided with a nickel layer, a copper layer and a silver layer from inside to outside. The rough surface copper-plating effect can be improved when the operation of the foil is treated, the light spot problem caused by the falling of the powder of the foil is treated, and the product quality and the finished product ratio are improved.
Description
Technical field
The utility model belongs to the electrolytic copper foil equipment technical field, particularly a kind of conductive rollers roller.
Background technology
Electrolytic copper foil has 2 Japanese inlet surface handlers, and 1 conductive rollers, other is stainless steel rider to original design conductive rollers in alligatoring; Since start; In alligatoring, curing process, have conductive rollers copper facing, the paper tinsel face falls the copper powder phenomenon always, and handling paper tinsel has bright spot; Quality product to the downstream client impacts, through analyze for the conductive rollers conductivity bad due to.Because of alligatoring, to solidify electric current bigger; Conductive rollers contacts not good with paper tinsel face moment in rotation process, form big potential difference, and this moment, paper tinsel was a negative electrode; The stainless steel conductive rollers is a negative electrode; Will form once more at the hair side of paper tinsel like this and electroplate, be seen as reflective bright spot from macroscopic view, the microcosmic electronic microscope photos is electroplated onto on the hair side for copper powder is arranged once more.
The utility model content
The purpose of the utility model is to provide a kind of can effectively reduce the conductive rollers roller that copper powder produces.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is following:
A kind of conductive rollers roller comprises stainless steel roller body, and its special feature is: be provided with nickel dam, copper layer, silver layer from the inside to the outside successively from this external surface of roller.The effect of nickel dam is to increase the copper facing effect, and the effect of copper layer is to reduce potential difference, and the effect of silver layer is to improve conductivity.
Preferably, the thickness of said nickel dam is 10 ± 1 μ m, and the thickness of said copper layer is 1 ± 0.02mm, and the thickness of said silver layer is 130 ± 10 μ m.
The utility model transform the stainless steel roller of former conductive rollers as silver-plated roller; Because of in operation process; The potential difference that produces between Copper Foil and the utility model (silver-plated roller) is much smaller than the potential difference that produces with stainless steel roller, and copper powder is difficult for being electroplated onto once more on the hair side of paper tinsel.Through inner practical application, the utility model can improve hair side copper facing effect when handling the paper tinsel operation, has solved processing paper tinsel dry linting and has produced the bright spot problem, has improved quality product and yield rate.
Description of drawings
Fig. 1 partly cuts open structural representation for the utility model.
Embodiment
As shown in Figure 1; A kind of conductive rollers roller; Comprise 316L roller body 1, and, electroplate the copper layer 3 (minimizing potential difference) of one deck 1mm then the nickel dam 2 of 316L roller body 1 plug-in one deck 10 μ m (increasing the copper facing effect); The silver layer 4 of re-plating one deck 130 μ m (raising conductivity), rubbing down is to desired size after having plated.
During enforcement, earlier 316L roller body 1 is carried out grinding, and then plug-in successively nickel dam 2, copper electroplating layer 3 and silver layer 4, last rubbing down is to desired size.
Claims (2)
1. a conductive rollers roller comprises stainless steel roller body, it is characterized in that: be provided with nickel dam, copper layer, silver layer from the inside to the outside successively from this external surface of roller.
2. conductive rollers roller as claimed in claim 1 is characterized in that: the thickness of said nickel dam is 10 ± 1 μ m, and the thickness of said copper layer is 1 ± 0.02mm, and the thickness of said silver layer is 130 ± 10 μ m.
