Anti-corrosion process method for the surface of dark green railway protective fence

In the metal mesh product industry, dark green railway protective fence refers to the protective fence mesh whose surface anti-corrosion treatment is made by the dip-plastic process. The dip-plastic protective fence production is an anti-corrosion process in which dark green raw material plastic powder is evenly applied on the surface of the metal mesh.
The dark green railway protective fence technology is what we often call electrostatic powder spraying. It uses static electricity to charge the plastic powder and adsorb it on the surface of the protective fence. After baking at 180 to 220°C, the powder melts and sticks to the protective fence. On the surface, protective fence products are mostly used outdoors, and the paint film presents a flat or matte effect. The raw material powders for protective fences mainly include acrylic powder, polyester powder, etc.

The dark green plastic-impregnated protective fence uses the phenomenon of corona discharge to adsorb the powder coating on the workpiece. It is quite different from the spray-coated guardrail. The coating of the spray-coated guardrail is thin, but the raw material quality is good, as long as there are no big scratches , the anti-corrosion ability has a longer service life than the plastic-impregnated guardrail, and the appearance color is also brighter. The price of dipped protective fence is at the mid-to-high-end level among guardrail factory products. It is suitable for use in highway guardrails, residential zinc steel guardrails, factories, park fences, scenic area guardrails and other public places, because the requirements for base materials are stricter. Usually, for fence net products of the same size, spray-coated guardrails are more expensive than dipped-plastic guardrails. Customers are asked to choose the surface treatment process according to their own needs.
