Plastic dipping fence

Usually the outer surface of the fence net needs to be processed. Generally, we first weld the original mesh and the column first, and then do the surface treatment, which is what people often say is dipping, which means to pass a polyester material through Above the steel wire attached at high temperature, so after the dipping treatment, the surface of the steel wire will have a protective layer commonly known as plastic, which makes the final outer surface of the steel wire thicker and the overall wire diameter also thicker. These two parameters are indispensable from the overall quality of the guardrail. If the steel wire is too fine, it will not become very thick after being dipped. If the surface layer of the dipping is too thin, it will make the life of the fence mesh A lot of short, if the immersion is too thick, the effect of the fence mesh will be deformed, so the appropriate amount of plasticization is a measure of the quality and technology of professional fence mesh manufacturers.

Benefits of dipping fence

We know that after the road fence is welded, it must be dipped in plastic. Dipping has two advantages. One is anti-corrosion, which can increase the service life; the other is beautiful. When the color of the dip is green, it is not only eye-catching, but also can blend with the surrounding landscape. However, after some fence nets are dipped in plastic, the plastic layer cracks and peels, and the plastic layer will fall off even with a light stroke. What is the reason?

The plastic powder commonly used in the dipping process includes polyethylene, polyvinyl chloride, and polytetrachloroethylene. When the highway guardrail net is dipped in high temperature, the powder melts into a liquid and is dipped into the net sheet. After cooling, it forms a steel-plastic film, which is firmly absorbed on the net sheet.
