Henan Dacromet equipment was first born in the late 1950s. In the cold seasons of America and Europe, the heavy snow on the roads seriously restricted the normal driving of cars. We sprinkled salt on the road to reduce the freezing point. temperature to improve road flow problems,
Unexpectedly, the chloride ions in the industrial salt attacked the steel structure, and the vehicle was seriously damaged, and a serious situation appeared. Mike Martin, a researcher in some developed countries, developed a metal zinc sheet and added aluminum. Highly dispersed water-soluble materials made of flakes, chromic acid, and deionized water as a solution. The material is attached to the metal structure, and is subjected to repeated coating and baking in a fully closed circuit to form a thin coating. The Dacromet surface treatment coating was successfully applied. Resist the damage of chloride ions, and the anti-corrosion technology has entered a new level, which has changed the shortcoming of the traditional anti-corrosion process.
Therefore, Henan Dacromet equipment technology was adopted by the military in some developed countries, and it became an anti-corrosion military technology. In the 1970s, the NDS company in the country introduced Dacromet surface treatment technology from this company in some developed countries. Buy out the right to use in the Asia-Pacific region, and hold some companies in developed countries.
The corrosion tonnage of steel parts in the country is large every year, so it pays special attention to anti-corrosion technology. After the improvement of Henan Dacromet equipment technology in the country, more than a hundred coating factories and chemical companies have developed very quickly in the country, many Other countries have also introduced Dacromet surface treatment technology one after another.
