Color-coated coils are color steel coils that use galvanized as the substrate and are coated with organic coatings of various colors. Coating: A method of metallic surface treatment that combines organic paint application and electroplating processes, electrocoat tinting should be a typical example. Color coating: It is based on cold-rolled and galvanized substrates.
After surface pretreatment (degreasing, cleaning, chemical conversion treatment), the process of applying paint in a continuous method (roller coating method), baking and cooling the product. Color-coated steel sheets are based on cold-rolled steel sheets and galvanized steel sheets. After surface pretreatment (degreasing, cleaning, chemical conversion treatment), hundreds of coatings are applied in a continuous method.
The shell is mainly made of color coating. Such as refrigerator door shell, refrigerator side panel, freezer door body, washing machine shell, microwave oven shell, air conditioner side panel, water heater shell, etc. Steel plate is a kind of composite material, that is, the composite of steel material and organic material, so it has the advantages of both: the existing steel plate has high mechanical strength and good formability. And the coating material has good decorative and corrosion resistance.
In foreign countries, this is called pre-coated steel plate. Product use: The coated steel plate has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It is used in the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc. A new type of raw material is provided, which has good effects such as replacing wood with steel, efficient construction, energy saving, and pollution prevention. The color-coated steel plate using galvanized steel plate as the substrate, in addition to zinc protection, the organic coating on the zinc layer plays a role of covering and isolation, which can prevent the steel plate from rusting.
