First, the development trend of cyanide-free zinc plating
From the current state of the art, the complete replacement of cyanide galvanizing in galvanizing has initially met the relevant conditions. This is because there are many varieties of galvanizing now, and various processes can be used to solve the problems that were previously solved only by cyanide galvanizing. For example, it is very common to use acid galvanizing for galvanizing. The coating obtained by zincate galvanizing has basically been able to compete with cyanide galvanizing. In addition to a small amount of military or special requirements, the realization of cyanide-free galvanizing in the electroplating industry is already the trend.
It should be pointed out that cyanide-free electroplating only solves the problem of highly toxic pollution caused by cyanide. It is not the case that the cyanide-free electroplating process can be used without sewage treatment. The effects of heavy metal ions or some newly introduced surface active substances are governed.
In addition, some of the chemicals introduced in cyanide-free galvanizing, especially some new chrome mixtures, some of which will not bring new problems to the environment, are not completely conclusive, therefore, from the perspective of clean production requirements, It is vital to develop cyanide-free galvanizing while avoiding new environmental problems.
Second, the development and research of new galvanizing process
Zinc plating, as a steel anode coating, has good protection for steel and is therefore the most widely used plating in electroplating. Zinc plating has been used as a plating material for protective coatings. The galvanizing additives that have been developed and applied are also based on the application of protective coatings. However, the emergence of high-gloss galvanizing additives has allowed the use of galvanizing to expand. In particular, with the addition of coloring technology, it has become possible to galvanize the decorative surface of the metal. Therefore, the development of galvanized decorative use is of great significance in the contemporary rise of non-ferrous metals such as copper and nickel and the shortage of natural resources.
In addition, some alloy coatings of zinc have excellent properties on the surface, which has opened up new fields for the functional use of galvanizing, such as zinc-iron alloy, zinc-nickel alloy, etc., which has great significance in corrosion resistance. It has been used in many countries in the automotive industry. It can be said that in the ancient and emerging plating of galvanizing, there are many processes and developments.
