[0047] The comparison between the three door panels produced by the above three production methods and conventional door panels is as follows:

[0048]

[0049] It can be seen that the door panels manufactured by the above three manufacturing methods have lower color difference values ​​on the edges, and the glue seams 4 cannot be directly observed by the naked eye, so the door panels appear beautiful as a whole.

[0050] In other embodiments, the UV primer roller coating amount can be 40g / m 2 Up to 50g / m 2 Any value of UV topcoat coating amount can be 130g / m 2 Up to 150g / m 2 The temperature of the hot air leveling channel can be any value from 35°C to 45°C, and the length can be any value from 15m to 25m.

[0051] The solid color UV paint furniture board in this embodiment is a door board, and other embodiments may be other furniture boards such as cabinet boards.

[0052] This embodiment sees Figure 1 , the ABS edge strip 2 is attached to the edge portion 11 of the plate 1 by means of adhesive, so the gap between the edge strip 2 and the edge portion 11 of the plate 1 is the adhesive seam 4. In other embodiments, the ABS edge strip can be attached to the edge portion of the plate by means of a clamping installation method, for example.

[0053] This embodiment uses ABS edge banding, which has a small heat shrinkage rate and is not easy to shrink when heated, and is not easy to cause cracking of the paint surface. In a non-preferred embodiment, a common edge banding with a larger heat shrinkage rate, such as a PVC edge banding, can be used instead, but the PVC edge banding is easy to shrink when heated, which may cause cracking of the paint surface.

[0054] In this embodiment, the adhesive 5 fills the adhesive seam 4, so the solid color UV paint 3 is applied to the adhesive seam 4 to cover it. In other embodiments, the adhesive 5 fails to fill the adhesive seam 4, so the solid color UV paint 3 is applied to the adhesive seam 4 to fill the adhesive seam 4 while covering the adhesive seam 4.

[0055] In this embodiment, the solid color paint is a solid color UV paint, and other embodiments may use other solid color paints, such as solid color PU paint.

[0056] In a non-preferred embodiment, the edge processing step may be eliminated.

[0057] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
