Laminated color steel plate is another product of color steel plate except embossed plate. It is made by coating adhesive on steel plate in advance, rolling (Fig. 1-13) and laminating plastic film on steel plate surface under certain temperature. The production process is that after the substrate is cleaned and chemically coated, the back paint is applied on the lower surface of the substrate by the fine coating machine, and the binder is applied on the upper surface. The back paint is baked in the curing furnace and solidified at the same time, the binder is activated. A laminating plastic film machine is set at the outlet of the curing furnace, and the laminating roller presses the organic film onto the surface of the substrate, and the binder is solidified after water cooling to make the organic film firm Bonding to the upper surface of the substrate. Laminate commonly used organic film is also called laminate, the substrate is usually vinyl film (PVC), fluoro resin coated warehouse, fast baking warehouse with small film (PVF), polyvinylidene fluoride (PVDF), polyester resin coating (PET), acrylic resin coating (PM-3 plan, surnamed Su Guo MA), etc.The laminate is resistant to moisture and water.
