Comparison of advantages and disadvantages of galvanized and colored PVC coatings for steel wire hangers
There are many ways to handle the surface of the hanger, such as fabric, flocking, foam, etc. This is a way to beautify the surface of the hanger, but strictly speaking, the surface treatment of the hanger mainly includes galvanizing, color PVC coating, electrophoresis, hot plating. Wait. In general, it is mainly used for iron hangers and stainless steel (alloy) hangers in iron hangers because the surface of the aluminum hanger will form a protective film to isolate oxygen. The most common hanger finishes are galvanized and colored PVC coatings. So what is the difference between them? What are the advantages and disadvantages?
The purpose of the galvanized and colored PVC coating on the wire hanger surface is to prevent the hanger from rusting and beautifying the hanger, which is common for galvanized and colored PVC coatings. However, the process is different, so the quality and price of the finished hangers treated differently will be different.
Galvanizing of steel wire hangers: One or more layers of other impregnation layers are plated on the surface of the wire hangers by electrolysis. Generally, zinc, chromium, nickel, imitation gold, rose gold, etc. are usually made of coated metals such as zinc and chromium. The oxidized anode enters the galvanizing solution, and the wire hanger itself acts as a cathode, and a coating is formed on the surface of the hanger by electrolysis. The main advantage of galvanizing is that it increases the corrosion resistance of the wire hanger, improves the wear resistance of the wire hanger, makes the surface of the hanger smooth and shiny, and the hanger is more beautiful and generous.
Wire hanger color PVC coating: Usually, the colored PVC coating is evenly sprayed on the surface of the hanger by a machine such as a spray gun. After drying, it is adsorbed on a wire hanger to isolate oxygen. Since the colored PVC coating component has certain toxicity, it will cause certain damage to the body during the process of colored PVC coating, so the colored PVC coating method on the surface of the hanger is gradually reduced, mainly by galvanizing. The quality of the wire hanger color PVC coating is mainly affected by the cleanliness of the colored PVC coating and the color of the PVC coating. Better quality coatings can effectively protect the wire hanger from oxidative corrosion. The main advantages of colored PVC coating are simple process, easy operation and fast drying.
Colored PVC coatings are much simpler in process than galvanizing and are therefore less expensive. From the end of the service life, the colored PVC coating is easy to fall, and its wear resistance is much lower than that of galvanizing; from the above point of view, galvanizing is more environmentally friendly than color PVC coating and does not contain any harmful substances. In general, the quality of the galvanized surface of the wire hanger is higher than that of the colored PVC coating, and the more layers of the galvanized hanger, the better the quality.
