At the beginning of the last century, except for the electroplating workshops of some product factories with a certain scale, most of the so-called electroplating industries were small workshops, so electroplating could not be formed in our country. In a public-private partnership in 1956, these small workshops were merged to form an electroplating factory with dozens of people, and only a very few factories had hundreds of people. At that time, the process and technology were still lagging behind, and they were actually in their infancy. In the middle and late 1950s, the electroplating industry began to develop. So far, it has been more than 40 years and then through merger and combination, gradually developed. By the mid-1960s, there have been many electroplating factories with hundreds of employees. At the end of the 1970s, there were a large number of township electroplating factories, especially in the suburbs of big cities. As we all know, electroplating is a heavily polluting industry in order to protect the environment, control pollution and implement sustainable development strategy. since the early 1980s, the state has included electroplating as a key industry for rectification. Major cities have set up electroplating professional adjustment offices to replan and adjust the electroplating industry. The factory buildings and facilities of the electroplating factory, especially for the treatment of electroplating wastewater, put forward clear requirements, by issuing electroplating production licenses to control the discharge of waste water from the electroplating industry, and by issuing electroplating production licenses, to control the total amount of electroplating plants. In Shanghai, for example, only one electroplating factory can be retained in a township. Since then, there has been a merger of the same series of electroplating plants in various places, and they have gathered together to carry out technical transformation, called electroplating centers. In some cities, there are often several electroplating centers, all of which are of a large scale, with land expropriation of at least dozens of mu. Some of them are more than 100 mu, and most of the investment is tens of millions of yuan. It is a pity that most of these electroplating centers are built in the urban efficiency combination area. due to the adjustment of the system and industry structure and the appreciation of land near the central area, most of these centers did not play the role of the original planning. it is a pity to say that it is a pity that it is moved to another use.
In the late 1960s, as countries around the world began to pay attention to environmental protection, electroplating workers realized that the discharge of cyanide and chromium-containing wastewater would bring serious pollution to river water quality. at that time, the focus of the work was mostly transferred to the trial of cyanide-free electroplating process, and the first thing to bear the brunt was to reform the galvanizing process. In the practice of cyanide-free electroplating process, the technical level of electroplating workers in China has also been greatly improved. This is true knowledge from practice. The practice of cyanide-free electroplating process has really trained a number of electroplating technical personnel. The following is a brief review and discussion of the more influential electroplating processes.
