Aluminum profiles are gradually used in guardrail products due to their small specific gravity, easy processing, and high mechanical strength. The aluminum profile is a contrasting, light metal with a silvery white sheen. The main material is aluminum guardrail arts, aluminum guardrail arts powder coating to be the reason is mainly due to the nature of aluminum. Aluminum is a lighter metal with a silvery white luster and its corrosion resistance is characterized by: First, the higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air to produce a thin and dense natural oxide film on the aluminum surface, which is faster and thicker than other metal oxide films. A lot, which prevents further corrosion of harmful gases and moisture in the air, and protects. Second, the mechanical strength is high, but the corrosion resistance is low. Although the corrosion resistance of pure aluminum is good, but the mechanical strength is poor, this restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of other metals such as magnesium, copper, zinc, etc. to aluminum to make various types. The mechanical strength of aluminum is greatly improved, and the application range is greatly expanded, but the corrosion resistance is inferior to that of pure aluminum, and thus it may be corroded by oxidation. This requires powder coating to protect the aluminum. The powder-coated aluminum art guardrail has high corrosion resistance, and also has many advantages such as diversified colors and good surface texture. During spraying, for some special shapes, adjust the position of the clamp in time to keep the profile at a certain angle of inclination at the position of the hanger to enhance the smoothness during operation and facilitate powder adsorption. In addition, for some heavy profiles, when using the clamp in the middle position, the elbow part should have a certain curvature, and the curvature of the clamp can ensure the profile is in the vertical position to ensure smooth production. In addition, as the number of times the conductive beams and hangers are recycled, the coating film will accumulate. The coating film itself is non-conductive, which will affect the conductivity of the conductive beam and the hanger, and thus affect the uniform distribution of the powder on the surface of the profile. The coating film on the conductive beam and the hanger should be cleaned in an appropriate manner.
