The processing performance of PVC foam board is the same as that of wood, and it is necessary to pay attention to the hollow cutting, because the hollow spacing is 23㎜, if you do not pay attention to the overlap of multiple pieces when cutting, resulting in the difference in spacing; It can be positioned by means of a latch with a tool to facilitate processing. Here is a look at the six common sense of PVC foam board processing:
1. According to the design drawings, the CNC engraving machine can be used to form, and then the surface is to be pasted with a durable plate or spray paint; But the hollow foam board special attention such as the surface is convex and concave uneven only the vacuum pump coating method material using 2㎜PVC plate.
2. Bending is only applicable to solid core foam board, hollow foam board is not suitable; The processing method is to use the left and right mold shell, cover the aluminum alloy plate on the surface of the wood template and heat the solid core foam board to the melting temperature of 70~90℃, and use the left and right mold to immediately roll out the surface of the foam board will not have all changes.
3. When self-adhesive PVC is produced, the surface can be produced according to the requirements of wood texture with different textures of packaging and printing, which can save excess processing procedures.
4. Can be PVC foam board surface spray painting solution, and the type can be divided into general spray painting, piano paint, porcelain paint according to different processing methods; When the piano paint is processed, anti-UV components are added to prevent the surface color from changing; In terms of surface strength, porcelain spray paint has the advantage of anti-scratch.
5. Then there is the common processing method. The surface is pasted with crystal tablecloths (usually single and double colored plate acrylic sheet), durable board and durable paper. In the edge wrapping part, the general processing is dominated by most automatic edge sealing machines, and the automatic edge sealing machine is divided into two kinds: roller type and track type. However, if the application of hollow polyurethane foam is proposed, it is proposed to apply a color similar to the surface coating raw material to prevent significant color bias when the paper is closed after pasting.
6. The drilling crawler automatic edge sealing machine is less likely to cause convex and concave uneven situation after the surface edge wrapping, and the adjustment of working pressure is also very key; The color of the foam board is also immediately processed with NC equipment. The raw material itself can reduce the relative density and increase the air content of the foam board itself according to the main use needs, so that the actual effect of heat insulation and insulation, sound insulation and noise reduction can increase the actual effect of reducing the cost, such as the net weight of the 15㎜ foam board to reduce its relative density and the net weight of the same volume 10㎜ foam board. At present, the existing manufacturers use the foam board to form the cabinet table or medium machine table cover shell, but there is a defect in the cabinet table forming, for the surface modulus is not good and easy to damage.
