New technology: How can electrophoresis prevent metal corrosion

For its excellent quality and high environmental protection, is gradually replacing the traditional paint spraying. According to incomplete statistics, the national electroplating industry, including hot dip galvanizing industry, annually discharged wastewater containing heavy metals is more than 400 million tons, solid waste gas containing heavy metals is more than 50,000 tons, and acid waste gas is more than 30 million cubic meters.

New technology: electrophoresis anticorrosion to prevent metal erosion

. "Speaking of anticorrosive technology we may not be musheng", Wuhan Kolier Chemical Co., LTD. General manager Li Zailiang told reporters that the traditional galvanized pipe is the steel pipe immersed in zinc liquid, so as to form a zinc cover layer on the surface of the steel pipe to play a decorative and anticorrosive role, its anticorrosive function is generally in 8 to 10 years or so. In recent years, it has been applied to the surface treatment of daily hardware. However, due to the hot galvanizing industry belongs to high energy consumption, galvanized with zinc pot requires high temperature of 450 degrees Celsius to melt zinc metal, so it took a lot of heat, power and metal resources, and the cover layer in the air through a long time and so on various aspects of corrosion, can produce corrosion and discoloration, cause secondary pollution. It is understood that the history of electrophoresis began in the 1960s, by the Ford Motor Company first applied to automotive primers. Wuhan Collier Chemical Co., Ltd. is at the forefront of the industry in the research and development of this technology.

Erosion of metal products costs the world more than $700 billion a year, and how to prevent metal erosion has become a nagging frustration. As we know, all daily metal materials will be affected by the natural environment such as atmosphere, sea water and soil in the process of use. With the extension of the action time, the function of the material itself will gradually decline and even be damaged. In addition to the shortcomings in electroplating, traditional paint spraying, also often adhesion is not strong, easy to fall off, anticorrosive function is poor, the surface of the equipment after spraying is coarse, low smoothness, environmental protection function is poor, severe pollution and a series of problems. The annual cost of metal aging worldwide is enormous. Electrophoresis anticorrosion technology is the direction to solve this setback. Under the environment of "environmental protection, energy saving and recurrent regeneration", electrophoresis anticorrosion technology has entered People's Daily life. According to statistics, the use of more than 90% of metal materials is steel, the world's existing steel and metal equipment about the annual erosion rate of 10%, the world's annual erosion loss is about more than 700 billion US dollars, generally speaking, because of erosion caused by the economic loss of about 2% to 4% of the gross national economic output. How to develop a new technology to solve the problem of erosion from the source has become the focus of the industry. The loss of metal products caused by erosion has become a major setback to people. Such severe pollution, electroplating industry in the sector area has become a "mouse across the street." Because of its wonderful anti-corrosion, anti-rust function, soon in the military industry has been widely used.
