Problems solved by technology

[0003] For electroplated chrome products, since some products are equipped with convex posts, during the electroplating process, when washed with water, water is easy to hide in the convex posts. After drying in an oven, the water in the holes still remains after the inspectors wipe it. After packaging, the logistics During the bumpy transportation, the residual water overflowed into the packaging bag and touched the surface of the product, causing dirt; in addition, after the product was cleaned, the water in the sink would become dirty water, and there was more water on the surface of the product before entering the oven, and there was watermark after drying; Dirty products will cause returns, which will result in loss of money and increase in production costs

Embodiment 1

[0022] Choose the Great Wall door trim, after degreasing, roughening, recycling, two reductions, palladium activation, degumming, chemical nickel plating, pre-copper plating, copper plating, acid activation, semi-bright nickel plating, bright nickel plating, nickel seal , chrome plating, reduction and drying processes, in which the previous process is washed into the next process by water. In the reduction process and the water washing process after the reduction process, such as figure 1 As shown, reduce the liquid level of the reduction tank and the washing tank after the reduction process, so that the liquid level is located at the bottom of the rib plate 1 on both sides of each tank, so as to ensure that the electroplating conductive plate of the electroplating rack is not in contact with each liquid level.

[0023] After the reduction process, add two spraying and washing processes, and the spraying and washing process uses a spraying and washing pool, such as figure 2 ...

Abstract

The invention relates to a treatment method for dirt on the surface of an electroplated chromium product. The treatment method comprises the processes of oil removal, coarsening, recycling, twice reducing, palladium activating, peptizing, chemical nickel plating, copper pre-plating, copper plating, acid activating, semi-bright nickel plating, bright nickel plating, nickel sealing, chromium plating, reducing and drying, wherein the next process is performed by washing after the front process, and in the reducing process and a washing process after the reducing process, liquid level of a reducing slot and liquid level of a washing slot after the reducing process are reduced; after the reducing process, twice spraying washing processes are increased; the drying process is performed after the spraying washing processes, and a hanger hung with an electroplated chromium product is unloaded to the ground through an unloading vehicle; and meanwhile, air curtain machines at the two sides of the unloading vehicle perform gas blowing on the electroplated chromium product. The treatment method has the advantages that: a dirt phenomenon on the surface of the product can be effectively removed, the comprehensive qualification rate of the product is increased, and great cost caused by goods return as the product is dirty is reduced.

Description

technical field [0001] The invention belongs to the technical field of preparation of electroplating products, and in particular relates to a treatment method for surface dirt of electroplating chromium products. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of the base material using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance, and enhance aesthetics. [0003] For electroplated chrome products, since some products are equipped with convex posts, during the electroplating process, water is easy to hide in the convex posts when they are washed with water. After drying in an oven, the water in the holes still remains after the inspectors wipe it. After packaging...
