Introduction to the principle of waveform guardrail powder spraying equipment

Wave shaped guardrails are a common infrastructure auxiliary tool, so people pay more attention to the service life of guardrails. Therefore, we need to take anti-corrosion measures for guardrails. Nowadays, there are generally two types of anti-corrosion measures for guardrails, one is galvanizing, and the other is powder coating equipment, among which more are painting processes. Today, we will discuss the principle of guardrail spraying equipment.

The principle of guardrail powder spraying equipment is a surface treatment method that sprays powder coating onto the surface of the product workpiece through an electrostatic spray gun. He uses static electricity to charge the powder, then adsorbs it onto the surface of the workpiece, and then sends the painted workpiece to a drying oven for high-temperature baking, producing a layer of coating on the surface of the workpiece to prevent corrosion. Generally speaking, the powders used in the spraying of waveform guardrails are mainly acrylic powder and polyester powder.

Wave shaped guardrails have many advantages, such as beautiful coating surface, good quality, strong adhesion, and secondly, fast spraying efficiency, which will not waste waiting time for curing. In addition, the coating has high corrosion resistance and wear resistance. The coating does not require dilution materials or topcoat, and will not cause pollution to the environment or harm to human health. Use more environmentally friendly technologies. After spraying the equipment, the guardrail comes in various colors, and different colors can be selected according to customer requirements. Most importantly, its cost is much lower. So most people choose powder coating equipment to spray paint.
