Problems solved by technology

[0003] However, when electroplating pearl nickel process, the phenomenon of serious color difference of the same batch of products often occurs, which affects the product qualification rate. There are many reasons for this phenomenon, mainly due to the large fluctuation range of the main salt content in the plating solution. , the product will gradually become brighter, which will increase the fluctuation of product color
[0004] However, another important reason for this phenomenon is that the heating pipe in the existing pearl nickel tank is a titanium tube. Due to the conductivity problem, the titanium tube will be coated after a period of use, and the product will grab current during electroplating, resulting in poor conductivity. , which in turn will lead to abnormal color of the product

Abstract

The invention relates to an electroplating pearl nickel color difference optimizing process. A plating part subject to semi-bright nickel plating treatment is fed into a dedicated pearl nickel grooveto be subject to pearl nickel plating treatment, the dedicated pearl nickel groove comprises a groove body, multiple tetrafluorohydrazine pipelines which are distributed at equal intervals from top tobottom and extend in the width direction of the groove body are arranged at the two ends of the groove body, and a partition board for separating the tetrafluorohydrazine pipelines from an inner cavity of the groove body is arranged on the inner sides of the tetrafluorohydrazine pipelines, and pearl nickel plating is carried out in the following component solution and condition that 460 to 470 g / L of nickel sulfate, 43 to 47 g / L of nickel chloride, 43 to 47 g / L of boric acid, 16 to 24 ml / L of a softening agent BSI, 0.8 to 1.6 ml / L of a wetting agent Ma-80, 2.4 TO 3.2 ml / L of a pearl nickel sand agent and 1.0 to 2.0 ml / L of a stabilizing agent PVA-124 are included; in the whole electroplating process, all components in the solution need to be regularly added, and stability of concentrationof all components in the whole electroplating process can be ensured. The electroplating pearl nickel color difference optimizing process has the beneficial effects that through the optimized process, surface color consistency of products to be plated is ensured, and the product yield is improved.

Description

technical field [0001] The invention belongs to the technical field of electroplating, in particular to an electroplating pearl nickel color difference optimization process. Background technique [0002] Generally, the products produced by electroplating are very bright bright nickel products, but some products do not need to be very bright. Most of these products require a more dull nickel layer. At this time, most of them use pearl nickel. Pearl nickel is also called satin nickel and satin. Nickel, fog nickel, water spray nickel, sand fog nickel, satin nickel and other good names. The pearl nickel coating has a white and soft color. The product has no reflection, and it produces slow reflection when it is directly exposed to strong light. It does not dazzle, and feels smooth and comfortable without fingerprints. [0003] However, when electroplating pearl nickel process, the phenomenon of serious color difference of the same batch of products often occurs, which affects t...
