Description

Technical Field

[0001] The invention belongs to the technical field of nickel electrolysis and relates to a method for processing the surface brightness and roughness of a nickel buckle. Background Art

[0002] Nickel buckles are widely used in national defense science and technology and precision electroplating industries. They have many advantages, such as smooth surface, good electrical contact performance, uniform current distribution, low dissolution voltage, low power consumption, uniform dissolution, less residue, less anode consumption, and good plating quality. In the actual production of nickel buckles, in order to reduce the impurities carried by nickel buckles and increase the glossiness of nickel buckles, the existing technology adopts the method of adding inorganic oxidants and reductants to the nickel buckle electrolyte. However, after the inorganic oxidants and reductants are added to the nickel buckle electrolyte, the actual utilization rate is not high, which affects the working environment and the electrolyte. The output nickel buckles often cannot effectively remove the impurities and burrs, and there are problems such as insufficient surface brightness. Summary of the invention

[0003] The purpose of the present invention is to provide a method for processing the surface brightness and roughness of a nickel buckle in response to the problems existing in the prior art, thereby solving the problem that in the existing nickel buckle production, when inorganic oxidants and reductants are added to the nickel buckle electrolyte, not only the working environment and the electrolyte are affected, but also the produced nickel buckles often cannot effectively remove impurities and burrs, and the surface is not bright enough.

[0004] To this end, the present invention adopts the following technical solutions: A method for processing the surface brightness and roughness of a nickel buckle. When a bright nickel buckle is required, the following steps are adopted: Step 1. First, prepare a hydrochloric acid solution with a mass percentage concentration of 15-35%, a hydrogen peroxide solution with a mass percentage concentration of 15-20%, and hot water for standby use. Then, the nickel buckle is peeled off from the anode plate after leaving the tank, and then pickled. Pickling refers to completely immersing the peeled nickel buckle in a hydrochloric acid solution with a mass percentage concentration of 15-35%, while turning the nickel buckle, and taking out the nickel buckle after 5 to 10 minutes, and controlling the hydrochloric acid solution.

[0005] Step 2, continue to rinse the nickel buckle; rinsing means that the nickel buckle after the hydrochloric acid solution is completely immersed in a hydrogen peroxide solution with a mass percentage concentration of 15-20%, and the nickel buckle is turned over at the same time. After 3 to 5 minutes, the nickel buckle is taken out and the hydrogen peroxide solution is drained.

[0006] Step 3, continue to scald the nickel buckle; scalding means that the nickel buckle that has been dried with hydrogen peroxide solution is completely immersed in hot water at a water temperature of 70-90° C., while turning the nickel buckle over, and after 3-5 minutes, the nickel buckle is taken out and the water is controlled to dry.

[0007] Step 4, continue to dry the nickel buckle; drying means drying the nickel buckle that has been dehydrated in a natural clean environment or under the action of wind, so that the surface of the nickel buckle is completely free of moisture.

[0008] Step 5, quality inspection is performed on the nickel buckles, and the nickel buckles are sealed and packaged after the quality inspection; the quality inspection refers to screening the nickel buckles after drying, and detecting unqualified nickel buckles and nickel scraps generated during the turning process of the nickel buckles.

[0009] Furthermore, the nickel buttons need to be turned over during the pickling, rinsing and scalding processes, so as to remove some surface attachments and burrs by means of friction between the nickel buttons.

[0010] A method for processing the surface brightness and roughness of a nickel buckle. When a matte nickel buckle is required, the following steps are adopted: the nickel buckle is firstly peeled off from the anode plate after coming out of a groove, and is directly scalded with hot water and dried without soaking or rinsing to obtain the matte nickel buckle.

[0011] The beneficial effects of the present invention are: 1. The present invention uses hydrochloric acid solution to pickle and dissolve and remove salt crystals deposited on the surface of the nickel buckle due to water loss, thereby maintaining the quality of the nickel buckle; 2. After the nickel buckle is washed with hydrogen peroxide solution after pickling in the present invention, the insoluble iron and other heavy metals on the surface of the nickel buckle can be removed, and the inorganic impurities attached to the surface of the nickel buckle can be removed, thereby improving the quality of the nickel buckle; 3. The present invention utilizes the friction between nickel buckles to remove burrs and residual attachments generated during the production process of the nickel buckles, and at the same time plays a role in polishing and brightening, avoiding secondary pollution caused by polishing with other materials; 4. The present invention utilizes a hot washing process to make the surface of the nickel buckle cleaner, remove stains attached to the surface, and wash away metal powder generated by the friction between the nickel buckles; 5. The present invention can also reduce processing steps and produce nickel buckle products with different quality requirements according to the quality requirements of nickel buckles in different use processes.
