Application of non - white smoke coplating agent in hot galvanizing of steel

Don't know whether you know, our traditional hot dip galvanizing technology mainly includes two kinds: hot galvanizing and dry wet hot galvanizing, now China's domestic production enterprises generally use dry hot galvanizing, this method has a disadvantage, in the whole process of hot dip galvanizing will produce lots of white smoke, the generation of white smoke to staff not only caused the bad work environment, at the same time white smoke to the atmospheric pollution, so how to reduce the white smoke in a hot dip galvanized steel to produce?

Several studies have found that a white smoke deposition aid can reduce the production of white smoke throughout the process. We have developed an ammonium chloride electroplating aid without white smoke, which can greatly reduce the smoke generation during hot dip galvanizing. There are many advantages of using coplating agent, which can improve the infiltration of molten zinc to steel, and then perfect combination of coating and steel surface, and also improve the corrosion resistance of workpiece. Using the coater also has the advantages of good thermal stability, non - toxic, and complete decomposition.

Generally, the temperature of the coater needs to be kept around 65-75 degrees Celsius. If the temperature of the coater exceeds this range, the self-drying effect will be poor, resulting in slow reaction speed between the steel surface and the zinc liquid, long time of infiltration, and increased production of zinc ash. So the temperature of the plating aid should be controlled well.

All in all, smokeless plating AIDS has made great progress in the hot dip galvanizing industry, not only creating a good working environment for our staff, but also reducing white smoke emissions, as well as giving us a warm and comfortable living environment.
