PVC foam sheet has a smooth surface, high hardness, and is not easy to be scratched. It is often used in various industrial buildings and home making, etc. What should be paid attention to in the design of PVC foam sheet?
1. It can be formed by engraving machine according to the design drawing, and then the surface should be affixed with beautiful anti-plate or baking varnish; but hollow foaming board needs attention, if the surface is uneven, vacuum molding can only be used. The material should be 2mm thick PVC board.
2, bending forming is only suitable for solid foaming board, hollow foaming board is not suitable; the processing method is to use the upper and lower molds, the aluminum mold is coated on the surface of the wooden mold and the solid foamed board is heated to a plasticizing temperature of 70~90 °C. There is no change in the surface of the shape foamed sheet by the upper and lower molds.
3. Self-adhesive PVC can be used to print different grain lines on the surface according to the requirements, which can save unnecessary processing procedures.
4, PVC foam sheet surface can be painted, and the general category can be divided into general paint, piano paint, ceramic paint according to different processing methods; in the piano paint processing will add anti-UV ingredients to avoid surface color changes; In the surface hardness, ceramic baking varnish is the advantage of scratch protection. The extruded board has high density and high strength, and the deformation stress of the extruded board due to its own deformation and temperature difference deformation is large.
