Color coated roll is a product obtained by applying organic coating on thin steel plate. It has good colorability, formability, corrosion resistance and decoration of organic compounds, as well as high strength and easy processing performance of steel
plate. It is a deep-processing product of iron and steel industry and high-efficiency energy-saving steel. In recent years, high quality and multi - purpose color coated steel plate has developed rapidly
High corrosion resistant color steel plate, high formability color steel plate, fingerprint resistant color plate and antibacterial color steel plate have a bright future. The market use of color coated board is mainly divided into three parts: construction,
household appliances and transportation. Among them, the construction industry accounts for the largest proportion, followed by the household appliances industry, and the transportation industry only accounts for a small part.
galvanized steel sheet and hot-dip aluminum zinc steel plate are used as base plates for building roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport, warehouse and freezer after being processed into corrugated
board or sandwich board conforming to polyurethane. The color plate of household electrical appliances is generally based on galvanized steel and cold plate, which is used to produce refrigerators, large air conditioning systems, freezers, bakers, furniture,
In the transportation industry, zinc plating and cold plate are commonly used as base plates, mainly used for oil pan, automobile interior parts, etc. If the galvanized steel sheet as the base material is not directly into a color coating process
after production, it may cause rust (white rust), dust and other pollution during transportation. If these can not be removed, it will affect the quality of color coating. The quality and all physical and chemical properties of the finished color coated
roll are closely related to the pretreatment. In addition, after galvanizing production, in order to prevent rust and oil, these oil should also be removed before color coating production.
