Talk about what you need to pay attention to the processing of PVC foam boardPVC foam board has the characteristics of anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, planable, easy thermoforming, hot bending, etc., so it is widely used in furniture and other fields, but special needs in processing Note, because this is related to the end of use time.
Processing of PVC foam board:
1. The foam material manufacturer introduces that it can be formed using an engraving machine according to the design drawing, and then the surface is to be pasted with Mena or baking paint, but the hollow foam board should be noted that if the surface is uneven, only the vacuum overmolding method can be used. 2 ㎜PVC board.
2. Bending forming is only suitable for solid foam board, hollow foam board is not suitable. The processing method is to use the upper and lower molds, cover the wooden mold surface with aluminum plate and heat the solid foam board to the plasticizing temperature of 70 to 90 ℃ In the meantime, the shape of the foam board surface is directly extruded by the upper and lower dies without any change.
3. When extruded PVC is manufactured, the surface can be printed with different grains according to the requirements, which can save unnecessary processing procedures.
4. The surface of the PVC foam board can be painted, and the general category can be divided into general baking paint, piano baking paint and ceramic baking paint according to different processing methods. When the piano baking paint is processed, anti-UV components are added to avoid surface color changes. In terms of surface hardness, ceramic baking paint is also used as an excellent anti-scratching advantage.
5. The introduction of foam material manufacturers is a common processing method. Paste a crystal plate (usually a single-sided colored acrylic plate), Mine board and Mine paper on the surface. In the edge sealing part, the general processing is mostly The automatic edge banding machine is mainly used, and the automatic edge banding machine is divided into two types: roller type and crawler type. However, when using hollow foam board, it is recommended to use a crawler type edge banding machine, which is less likely to cause unevenness after the surface edge banding The pressure adjustment is also very important.
