Category:Color coated board series
Product Name: color coated board, also known as color steel plate, color plate
The basic concept of color-coated plate: cold-rolled strip steel, galvanized steel strip (electro-galvanized and hot-dip galvanized) as the substrate on the continuous unit, subjected to surface pretreatment (degreasing and processing), coated by roller coating One or more layers of liquid coating, the board obtained by baking and cooling is a coated steel sheet. Since the coating can have a variety of different colors, it is customary to refer to a coated steel sheet as a color coated steel sheet.
Process flow
The color coated steel plate is made of cold-rolled steel plate and galvanized steel plate, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner (roll coating method), and baked and cooled. Into the product. The main production process of the common two-coating two-bake continuous color coating unit process is: unwinding-pretreatment coating-baking-post-treatment-winding.
Color coated steel substrate type:
Cold rolled substrate color coated steel sheet
The color plate produced by the cold-rolled substrate has a smooth and beautiful appearance and has the processing property of the cold-rolled sheet; however, any fine scratch of the surface coating exposes the cold-rolled substrate to the air, so that the exposed iron is quickly Generate red rust. Therefore, such products can only be used for temporary isolation measures and indoor materials that are not required.
The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated plate also protects against rust and has a longer service life than hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 1801 gram per square (double-sided), and the galvanized amount of the external thermal zinc substrate of the building is up to 275 gram per square.
Hot-dip aluminum-zinc color coated board
According to requirements, hot-dip aluminum-zinc steel plate can also be used as color coated substrate (55%AL-Zn and 5% Al-Zn).
Electroplated zinc color coated board
The electroplated zinc plate is used as the substrate, and the product obtained by baking with the organic coating is an electrogalvanized color coated plate. Since the plating of the electrogalvanized plate is thin, the zinc content is usually 20/20 g/square, so the product is not suitable. Use outdoors to make walls, roofs, etc. However, due to its beautiful appearance and excellent processing properties, it can be mainly used in home appliances, audio, steel furniture, interior decoration and so on.
Product Usage
Buildings or buildings made of color-coated steel sheets are often subjected to rainwater for a longer service life, otherwise they are affected by the action of sulfur dioxide gas, salt and dust. Therefore, at the time of design, if the inclination of the roof is larger, the dirt is less likely to accumulate dirt and the like, and the service life is longer; for those areas or parts that are not washed frequently by rain, it should be washed regularly with water.
