Example Embodiment

[0167] The processing method adopted in the present invention is now described in detail:

[0168] The first step is the semi-bright nickel plating process. The coating has excellent leveling ability and ductility; non-coumarin type light agent can be continuously filtered by activated carbon; the plating solution is easy to control, and no harmful products will be produced after long-term operation; the coating does not contain sulfur and has extremely high corrosion resistance ability.

[0169] Element

[0170] The effect of the above-mentioned components in the plating process is:

[0171] 1. Nickel sulfate and nickel chloride: Nickel sulfate and nickel chloride are Ni in the plating solution 2+ Its content is maintained by the rapid dissolution of the anode. The concentration of nickel chloride should be maintained within the standard range of 35-45g / L. The content of nickel chloride is extremely important for the speed of anode corrosion, the conductivity...

Abstract

The invention discloses an electroplating productive technology in metal finishing domain, which is characterized by the following: using to metallic product or plastic rubber product; adopting different dispense of electroplating liquid; proceeding scientific control density of coating liquid, current strength, temperature and so on technical parameter; optimizing the best parameter range. This craft can plate good product, which possesses little raw material consumption and high productive efficiency and so on multiple effects.

Description

【Technical field】 [0001] The invention belongs to the electroplating production process in the field of metal surface treatment, in particular to a production process that adopts a multilayer electroplating process to make workpieces have excellent anti-corrosion performance. The above-mentioned production process can not only be applied to the decoration and anti-corrosion of metal products, but also can be applied to plastic products. 【Background technique】 [0002] Now with the development of technology and the progress of society, the requirements for the appearance of products are constantly improving. As a traditional surface treatment process, electroplating process has been widely used in many fields. The electroplating process currently used mainly has two functions, one is decorative electroplating with the main purpose of appearance decoration; the other is functional electroplating with anti-corrosion as the main purpose; in some industries, parts are required t...
