Process of Color-Coated Steel Plate
The color-coated steel plate is made of cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), the coating is applied in a continuous method (roller coating method), and it is made by baking and cooling Products.
The common two-coat two-baking continuous color coating machine process flow main production process is: uncoiling → pretreatment → coating → baking → post-processing → coiling.
Application of Color-Coated Steel Plate
The coated steel plate has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.
It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc. Wood, efficient construction, energy saving, pollution prevention and other good effects.
In addition to zinc protection, the color-coated steel plate using galvanized steel plate as the substrate, the organic coating on the zinc layer plays a role of covering and isolation, which can prevent the steel plate from rusting, and the service life is longer than the galvanized steel plate, according to the introduction coating The service life of steel plate is 50% longer than galvanized steel plate.
