As an important surface engineering technology and a new electroplating technology, cinnamic acid has a history of more than 60 years since 1980 applied for silver plating patent. Since the 20th century, with the progress of science and technology and the continuous improvement of industrialization, the surface treatment of automobile, mechanical equipment, aviation, electronics, light industry and other industries can not be separated from electroplating. Today, electroplating has developed from general decorative protection to high corrosion resistance and functionality. It is widely used in the basic processing industry in the fields of electronics industry, national defense industry and cutting-edge technology, and plays an important role in China's national economic construction. However, while electroplating plays a great role, it also seriously harms people's health and destroys the surrounding environment. In particular, zinc plating, which accounts for 45%-50% of the whole electroplating industry, whether cyanide-containing zinc plating or cyanide-free zinc plating (mainly sodium chloride), is accompanied by serious environmental problems, so that in 2008, the country had to implement the new "New Discharge Standard for Electroplating Pollution". The new standard gives electroplating enterprises a buffer time of two years to replace equipment and update raw materials. But this is still the same for the electroplating industry: upgrading requires a lot of investment, which will inevitably lead to a sharp rise in prices, which is undoubtedly equivalent to dying in fierce competition, and the only consequence of not upgrading is waiting for death. Therefore, whether we can find a low-cost raw material can make the electroplating industry embark on the road of green development and become a lifeline to get rid of the dilemma of electroplating "two deaths" and survive. China is a big electroplating country, and all kinds of advanced technologies are reflected in China. Cinnamic acid can be used as brightener, corrosive agent and additive in electroplating. Commonly used in chloride zinc plating, tin plating and other electroplating protection layer industries. Cinnamic acid can be used not only as brightener and carrier brightener for acid zinc plating such as sulfate zinc plating brightener and potassium chloride zinc plating brightener, but also as auxiliary brightener for other brightener products. Cinnamic acid can refine the crystallization of the coating, promote the uniform dispersion of the main brightener insoluble in water in the plating solution, further expand the bright current density range of the plating solution, improve the cathodic polarization of the plating solution, strengthen the low-grade bright effect and obtain a fully bright coating; It can relatively improve the dispersion and covering ability of the plating solution, and has the characteristics of fast zinc feeding speed, fast luminous speed and low consumption. Because common main brighteners such as benzylidene acetone, cumaldehyde, benzophenone, o-chlorobenzaldehyde, etc. can only play a bright role in a certain range of current density, an ideal coating can not be obtained when used alone, and cinnamic acid can achieve a synergistic effect when used together. As a brightener, cinnamic acid broadens the operating temperature. Generally, at 1~70℃, the dispersion ability and deep plating ability of the plating solution are still very good. The obtained coating is fine and bright, with low brittleness, low consumption, self-inhibition of impurities and strong corrosion resistance. Adding carnosic acid will not produce toxic or irritating gas, waste water, waste gas, noise, waste residue and other pollutants, and it does not contain radioactive, corrosive and toxic substances, which can save the later environmental protection treatment and greatly reduce the cost. At the same time, cinnamic acid is cheap and convenient for storage and transportation, which is indeed the gospel of electroplating. Hubei Yuancheng Pharmaceutical Co., Ltd. is the only large-scale enterprise producing cinnamic acid in China. At present, I have long-term cooperation with this enterprise. I'm Xiao Gong 027-883227 15, the salesman of Yuancheng. I believe these latest information can bring new spring to electroplating industry in China. 20 12, I wish all enterprises new opportunities!
