Film color coating board has a beautiful appearance, with excellent fire prevention, corrosion resistance, acid and alkali resistance and other properties, fire resistance, pollution resistance.But the price is higher, its products are mainly used in home appliances, furniture, interior decoration and car and ship interior decoration.Most steel base color coating plate requires flat zinc flower, zero zinc flower hot galvanized steel roll or electroplating galvanized steel roll, in recent years there is a trend to increase the hot galvanized aluminum Galfan, aluminum zinc Galvalume and other alloy coated steel plate as substrate plate; film color coating plate using cold rolled roll as substrate, some products also stainless steel substrate.No matter which substrate is used, its surface, plate shape and size accuracy have very high requirements.The type and color of the back paint, when the back is only one layer, this back paint generally does not consider corrosion resistance, the film thickness is usually 8~10 m.At this time, if the hot galvanized substrate is selected, in general, the inside of the building is ok.Heat resistance of color coated plates, ordinary thermal galvanized products usually use a temperature of no more than 230℃, and change color at 250℃, while aluminum galvanized plates can be used for a long time in a 315℃ environment.Baosteel heat-resistant galvanized steel plate changed less in color for 120 hours at 300℃.
