What is the difference between galvanizing and galvanizing?

Release date:2018-06-28 author: click:

In more and more places, hot-dip galvanizing and hot-dip galvanizing can be used. What is the difference between hot-dip galvanizing and hot-dip galvanizing? The overflowing hot-zinc-zinc bolts will give you a brief introduction.


    Zinc infiltration is a physicochemical reaction to be heated. The workpiece, the zinc powder and the infiltrant are heated in a closed furnace, so that the zinc powder atom accelerates and penetrates into the workpiece structure, and the surface can form a protective layer of zinc + zinc iron layer structure. The heating temperature may be around 500 degrees, and the temperature is high and the percolation rate is fast. Similar to carburizing and nitriding.


    Zinc plating is a purely physical reaction. At normal temperature, the zinc powder is placed in the container with the workpiece and the steel ball (glass beads), and the steel ball is hit on the workpiece while the zinc powder is hit on the surface of the workpiece, so that the workpiece is coated with a layer of zinc powder. It is a physical process, there is no chemical reaction, no need to warm, the rotation speed is very slow, 20~30 revolutions per minute. Of course there may be more advanced process equipment.
