Fasteners are common components in mechanical equipment and play a crucial role. However, corrosion of fasteners during use is a common cause of damage. In order to prevent corrosion of fasteners during use, surface anti-corrosion treatment is essential.

There are various methods for surface anti-corrosion treatment, such as spray painting, cold galvanizing, alloy catalytic liquid, and so on. And among them, the degree of corrosion resistance varies depending on the production process. Next, we will introduce the process steps and characteristics of spray painting treatment, cold galvanizing, and alloy catalytic solution in sequence.

1. Painting treatment

Process: The surface is first degreased, pickled, phosphated, passivated, or pre treated with a shot blasting machine for surface slag and rust removal. After that, an anti rust primer is sprayed once, and then a magnetic topcoat is sprayed for surface protection treatment.

Features: Uniform and consistent color; Sense of solidity; Excellent anti-corrosion performance. However, non professional manufacturers only consider winning bids at low prices and often do not undergo phosphating or shot blasting pre-treatment. They directly spray paint, which has a short anti-corrosion time and poor effectiveness; Alternatively, using small factories to produce inferior paint can reduce costs, as harmful substances are difficult to disperse and may have an odor for a certain period of time.
