According to different coating processes, the steel plate is divided into three types: pvc foil steel plate, pvc composite steel plate, and pvc coated steel plate.
Pvc-coated steel plate polyvinyl chloride sol is used as the color coating of the steel plate, the dry film thickness is between 100-200um, and the dry film thickness of the general coating steel plate is only about 20um. Polyvinyl chloride sol coating is thermoplastic. Therefore, after coating and drying, the product will generally enter the embossing process directly, making its surface rich in texture. Improve decorative performance. In addition, pvc coated steel plate has good flexibility, suitable for secondary processing, such as bending, pressure, etc., and bending to a small angle without the phenomenon of coating shedding. However, there are disadvantages of aging and discoloration.
Pvc foil steel plate
Pvc foil steel plate is also called plastic film steel plate. The plastic film pre-printed with wood grain, cloth grain or leather grain is adhered to the strip steel by a laminating method. This process is widely used in the construction industry, transportation industry and electric appliance industry, and it is the main component of the organic coated steel sheet. product. There are four main types of organic film materials: polyvinyl chloride, polyvinyl fluoride, thermoplastic acrylic and polyethylene terephthalate. The advantages and disadvantages of this product are basically the same as those of pvc-coated steel plate
Pvc composite steel plate due to the former two kinds of steel plates are easy to aging, easy to change color, poor durability and other shortcomings. In order to improve this situation, there has been a process of coating an acrylic coating on a pvc-coated steel plate or a pvc-coated steel plate, which effectively enhances the durability and corrosion resistance of the pvc steel plate. Pvc steel plate can also be made of sandwich panels like color profiled steel plates to improve its thermal and acoustic properties. The thickness of the insulation material is generally 15-17 μm polystyrene foam or rigid polyurethane foam. This foam is a closed cell structure and has good thermal insulation properties. In the color steel plate interior decoration industry that has risen in recent years, both coated plates and pvc-coated plates have become the main decorative materials, and the shapes of press plates or buckle plates have also become more and more.
