Method of insulating galvanized chains
Release time:

In the plating solution processing of galvanized chain, the parts of the fixture in the plating solution, except the conductive parts in contact with the workpiece, should be insulated. Otherwise, metal will be deposited in these parts, causing unnecessary loss of electric energy and metal, and may also cause abnormal distribution of the plating solution, making the plating layer uneven or even locally unplated. The insulating material of the hangers should have good chemical stability, good heat resistance, good insulation, good bonding with the hangers and a certain degree of mechanical strength.

Galvanized iron chain insulation material should have good chemical stability, and good heat resistance, the following small will come to you to introduce what are the methods of insulation treatment:
The first is the wrapping method, which is to use polyvinyl chloride insulating tape to wrap the parts that need to be insulated, and the round bar can also be sleeved with a plastic pipe of suitable diameter.
Then, the second method is to paint insulating paint, galvanized iron chain needs to be painted with insulating anticorrosive paint after surface treatment such as rust removal, oil removal and drying. Again is the plastic coating method, after rust removal, oil removal, drying and other surface treatment, heated to about 250 ℃, inserted thermoplastic plastic powder, the plastic powder melts and adheres to the surface to form a thin plastic film.
