When we use alkaline galvanizing additives, we need electrolysis to remove heterogeneous metal impurities, but the electrolysis time is not well grasped, so what do we need to do?
Many customers are sensitive to the price of acid copper brightener, they want to buy affordable, cost-effective products, often they will buy cheap, the use of poor acid copper brightener. So what factors are related to the price of acid copper brightener?
In the production of hard chrome additives, we should try our best to prevent trivalent chromium from rising. The reason is that the trivalent chromium is low, just add the appropriate amount of reducing agent can make the hexavalent chromium reduced to trivalent chromium, such as hydrogen peroxide, ethanol (that is, industrial alcohol), oxalic acid and so on. Adding oxalic acid is easy to quantitatively calculate: theoretically 10g/L oxalic acid can produce 2.75g/L trivalent chromium. Using hydrogen peroxide is not so good, and you have to add heat to the process to let it evaporate.
In the production process of using nickel plating additives, when electrolytic treatment of impurities is required, how should the temperature and pH value be selected?
In the field of precision manufacturing, quality disputes caused by insufficient hardness of plating are common. A plating plant has feedback, customer requirements for steel workpiece hardness after nickel plating ≥ 40HRC, but the traditional process after plating only 35HRC, heat treatment barely meets the standard but accompanied by the risk of brittleness. This plating hardness and toughness of the contradiction, just the direction of the breakthrough in the phosphorus chemical nickel plating solution.
When using nickel plating brightener, are you often troubled by iron impurity contamination? Is it that after using electrolysis method, not only can't completely remove impurities, but also lose a lot of nickel salt? Is not the use of impurity remover but become serious, iron ions can not sink, the plating solution becomes cloudy, add hydrogen peroxide to adjust the PH also can not? This article will tell you how to solve the problem.
