Analysis Of Environmental Protection Electroplating Products And How To Enhance Industry Competitiveness

With the development of the economy, people's living standards are getting higher and higher, and they are paying more attention to health and environmental protection issues. People's concept of environmental protection has risen from the initial environmental pollution caused by pollution discharge from production enterprises such as electroplating, washing and dyeing, and chemical industries to the concern of whether electroplating coatings on daily products sold in the market cause harm to human health. This is a major challenge for the electroplating industry and a major issue that must be addressed, At the same time, it is also an opportunity for the development of electroplating enterprises. Only by achieving true environmental protection for electroplating products can the electroplating industry continue to improve on the path of sustainable development.
At present, most daily products use nickel plating technology, and direct contact with nickel for a long time can easily cause skin allergies and even blood allergies. Chronic inhalation of nickel can cause degeneration of the heart, brain, liver, etc. Currently, EU countries have strict control over the release of nickel from products that come into contact with human skin (<0.5mg/cm2 per week). Nickel can cause harm to the human body. What are the nickel containing products that are exposed to in daily life, and what are the health and environmental standards for their use and requirements? Please refer to the table below for details:
From the above table, it can be seen that nickel containing products are ubiquitous in our daily lives and constantly affect people's health. Whether from the perspective of health and environmental protection or improving product performance, the use of nickel free electroplating technology is the trend. However, many electroplating factories are not clear about the concept of nickel free electroplating and mistakenly believe that nickel free electroplating is not the use of nickel plating. After copper plating, they skip the nickel plating process and directly deposit gold, silver, and other surface coatings, resulting in rapid discoloration of the products, Seriously unqualified quality; Some electroplating plants also try to replace nickel plating with copper tin alloy plating, but only symbolically plating for 1~2 minutes. The coating thickness is obviously insufficient, leading to the poor tarnish resistance of products. The real nickel free electroplating is to replace the nickel plating of the same thickness with the bronze plating of more than 3 microns, so as to obtain the anti-corrosion performance of the coating which is equal to or even stronger than the nickel plating layer, and realize the real nickel free electroplating.
