In electrolyting precipitation process, the size of the current density of negative electrode has remarkable influence to the quality of nickel foil, and at the bad mechanical property of low current density district nickel foil, this causes owing to the nickel foil crystal structure is thick; And in high current density region, the mechanical property of nickel foil descends, this is because the certain concentration polarization of polar region generation under high current density, cause subsalt on negative electrode, to be separated out, the nickel foil crystallization is loose, surface irregularity causes, so the current density of negative electrode is the 800-3000 amperes per square meter in electrolyting precipitation process, is good with the 1400-2200 amperes per square meter again.
The pH value of electrolytic solution also has remarkable influence to the electrolytic deposition of nickel and the quality of nickel foil, anodic current efficiency increases along with reducing of electrolyte PH value, illustrate that increasing acidity helps the anodic dissolving, cathode efficiency reduced when but pH value was low, the mechanical property of nickel foil is not good yet, this separates out on negative electrode and causes owing to hydrogen, it is many more that the high more hydrogen of acidity is separated out, the separating out of hydrogen on the one hand is accompanied by the generation of nickelous cyanide and dissociates, make nickel foil produce certain stress, the mechanical property variation, reduced the current efficiency of negative electrode simultaneously, the tensile strength of nickel foil descended when pH value was high, this is mixed in the nickel foil and causes owing to subsalt precipitation appears in the cathodic area, under same current density, in the low current density district, elongation δ (being unit elongation again) increases along with the increase of PH, in high current density region, elongation δ descends along with the increase of pH value, the pH value of taking all factors into consideration electrolytic solution is controlled at 1.8-3.4, again with at 2.4-3.4 for better, because the height of pH value, quality to nickel foil has bigger influence, so must control the pH value of electrolytic solution, with boric acid is buffer reagent, keeps solution-stabilized pH value, and boric acid can suppress the rapid rising of the pH value that cathodic process causes owing to separating out of nickel effectively, improve cathodic polarization simultaneously in addition, improve the effect of nickel foil performance, thus 30-45 gram/liter boric acid contained in the electrolytic solution, again to contain 38-45 gram/liter boric acid for well.
When making anode with electrolytic nickel, under the high cathode current density, be easy to produce anode passivation, must add a certain amount of anode activator nickelous chloride, chlorion produces certain activation to nickel anode, when nickelous chloride content hangs down, it is little that the nickel foil mechanical property is influenced by it, when nickelous chloride content is big, the tensile strength of nickel foil improves along with the increase of nickelous chloride content, nickelous chloride content is when 10-35 gram/liter, cathode efficiency and anodic current efficiency are the most approaching, and nickelous chloride can stabilizing ion concentration in this scope.When nickelous chloride content was increased to 55.6 gram/liters, nickel foil just may come off from negative electrode automatically in deposition process, and along with the increase of nickelous chloride content, nickel foil surface pockmark defective increases.
Strike is produced nickel foil, impurity in the electrolytic solution is to the production technique of nickel foil and the effectively big influence of quality of nickel foil, trace impurity iron, copper, zinc, the existence of nitrate radical and organic impurity, not only influential to the operation of process, and the mechanical property of nickel foil also had a significant impact, in addition, owing to use soluble anode, to produce the anode sludge inevitably, therefore except to raw material sulphuric acid nickel, have outside certain requirement as purity of raw materials such as anodic electrolytic nickels, also must make purifying treatment to electrolytic solution, the method of all knowing with the those of ordinary skill under this area purifies, to handle by charcoal absorption from the electrolytic solution that upper part of the electrolytic cell overflows, remove out organic impurity, carry out the electrolytic cleaning of low current density then, the low current density of its negative electrode is 0.1-0.5 ampere/square decimeter, adopt the undaform negative electrode in the purifying electrolysis groove, used for electrolyte woven dacron behind the electrolytic cleaning removes by filter small solid particulate, electrolytic solution after will purifying again gives heat to 50-70 ℃, be good with 61-70 ℃ again, enter electrolyzer from the bottom of electrolyzer, the flow that the electrolytic solution of purification preheating enters electrolyzer equates with the flow of the electrolytic solution to be clean that overflows from upper part of the electrolytic cell.
In order to be collected in the anode sludge in the electrolyting precipitation process, the anode basket that fills as the anodic electrolytic nickel is surrounded by the anode of being made by woven dacron outward, so that the anode sludge is removed by filter.
The electrolytic deposition of nickel foil is a rotatable titanium roller or rotatable stainless steel roller to be housed as negative electrode in one, electrolytic nickel (containing in the anode basket) is as anode, fill in the electrolyzer of nickel sulfate solution and carry out, be contained in the anode basket is that the scrap stock of electrolytic nickel are processed into alkynes or pie as the anodic electrolytic nickel, the anode basket is made of titanium, nickel sulfate electrolyte is controlled at (50-70 ℃ of certain temperature, be good with 61-70 ℃ again) and the control electrolytic solution speed of circulation certain in the polar region, under certain current density, carry out electrolysis, nickel ion is deposited on the cathode roller of slow rotation, peel off down nickel foil from cathode roller continuously again, wash by the method known to the one of ordinary skill in the art, oven dry, batch nickel foil and become the nickel foil of continuous rolling, in conditions such as current density one regularly, the rotating speed of cathode roller is made in adjusting, and produce the nickel foil of different thickness, the electrolytic solution continuous purification, recycle, anode nickel regular replenishment, pole span can be controlled between 25 millimeters-50 millimeters.
