Embodiment Construction

[0011] The present invention adopts the following technological process: upper hanging → cathodic degreasing → anode degreasing → water washing → water washing → water washing → activation → water washing → water washing → counter electrode → electroplating → recovery water washing → recovery water washing → water washing → controlled drying → bottom hanging.

[0012] The water washing process of the present invention includes a circulating water treatment system, which realizes the recycling of water resources in the production process. Aiming at the characteristics of electroplating wastewater, the present invention adopts ultrafiltration membrane as the core processing component, and its material is hollow fiber of modified PVC. The surface activation layer is dense, and the support layer is a double-row fat-like structure, which has good removal ability for colloids, suspended particles, chroma, turbidity, bacteria, and macromolecular organic matter. When in use, determine ...

Abstract

The invention belongs to the field of metal electroplating, and particularly relates to an electroplating energy-saving method. The electroplating energy-saving method comprises the following technological process of racking, cathode degreasing, anode degreasing, washing, washing, washing, activation, washing, washing, antipole operation, electroplating, recycling washing, recycling washing, washing, draining and taking down. According to the washing process, a circulating water treatment system is included, and recycling of water resources in the production process can be achieved; according to the electroplating process, an automatic dosing machine, a filtering machine, an electric control ampere meter and a temperature alarm device are added into the electroplating process. The time in the electroplating process is controlled to 30 minutes to 60 minutes. The electroplating energy-saving method has the beneficial effects of being reasonable in process setting and ideal in electroplating effect, achieving recycling and reutilizing of energy resources, saving production cost and reducing the pollution to the environment.

Description

[0001] technical field [0002] The invention belongs to the field of metal electroplating, and in particular relates to energy saving of electroplating. Background technique [0003] In modern manufacturing, a large number of metal products are used, and plating on metal products is also a common production method. Electroplating is the process of plating a thin layer of other metals or alloys on the metal surface by 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 corrosion and improve wear resistance. Sexuality, conductivity, light reflection and aesthetic enhancement. However, the existing electroplating process is not only complicated in process, but also high in cost, unreasonable in setting of process links, and serious energy waste. Contents of the invention [0004] The object of the present invention is to provide an electroplating energy-sav...
