Brand tag physical properties of post-electroplating oil spraying-A
Brand tag (brand signage) after plating the physical properties of the spray oil will be plated and spray oil material and its process of the joint influence, specific performance is as follows: Brand tag hardness Plating layer influence plating layer (such as nickel, chromium, gold, and so on) itself has a certain hardness, can improve the wear resistance of the signage. For example, the hardness of hard chrome plating layer can reach 800-1200 HV, which can effectively resist scratches and abrasion. Oil spraying influence The hardness of oil spraying layer (such as UV paint, polyurethane,and so on) is usually lower than that of plating layer, but it can be enhanced by adding hardener or choosing high hardness coating. The hardness of the sprayed layer is generally between 2H-4H (pencil hardness). Brand tag combined performance The overall hardness of plated and then oiled signage depends on the synergistic effect of the plating and oiled layers. The plating layer provides the base hardness, while the oil spray layer provides protection and decoration. Adhesion Combination of plating layer and spray oil The surface roughness and chemical properties of the plating layer will affect the adhesion of the spray oil. Usually, appropriate surface treatment (polishing, activation) is required after plating to improve the adhesion of spray oil. Brand tag test standard According to 100-gauge test or the grid method,we can evaluate Adhesion , and high quality plating and spraying signage should reach grade 4B-5B. Corrosion resistance The role of plating layer plating layer (such as nickel, chromium) itself has good corrosion resistance, can prevent the base material (such as copper, zinc alloy) is oxidized or corrosion. The role of the oil-sprayed layer oil-sprayed layer can further isolate moisture and corrosive media, but need to choose the excellent chemical resistance of the paint (such as…
