Embodiment 1
[0049] A method of making ecological doors, as attached Figure 1-8 As shown, it includes the following steps: the method includes five steps. The first step is to make the single boards symmetrically arranged in a horizontal-vertical-transverse structure into a multilayer board, and the second step is to stack two multilayer boards with a thickness of 15-25mm. A standard door panel. In the third step, the surface decorative paper impregnated with melamine impregnated resin and the softened density board are pressed together. In the fourth step, the milled door panel and the door panel are hot pressed into an ecological door. Spray, transfer wood grain, and spray paint on the side of the door step by step.
Embodiment 2
[0051] The difference between this embodiment and the first embodiment lies in the manufacturing method of the ecological door, as attached Figure 2-4 As shown, in the first step, the veneers are symmetrically arranged in a horizontal-vertical-horizontal structure to produce a multi-layer board, which includes five processes. In the first process, the logs are cut into veneers, and the logs are cut into 2mm sheets. After the veneers are naturally dried to a moisture content of 15-20%, the dried veneers are divided into first-level veneers, second-level veneers, and three levels for storage;
[0052] In the second process, the classified veneers are dried, and the veneers are placed in a vacuum drying box, and the veneers are dried to a moisture content of 6-8%;
[0053] The third process is to apply glue to the dried veneer. The first-level veneer is used as the upper and lower panels, the bottom surface of the upper panel is glued, the top surface of the lower panel is glued, and ...
Embodiment 3
[0057] The difference between this embodiment and the first embodiment lies in the manufacturing method of the ecological door, as attached Figure 5 As shown, the second step is to stack two multilayer boards with a thickness of 15-25mm into a standard door panel, the standard door panel thickness is 30-50mm, and the adhesive surface of the door panel with a thickness of 15-25mm is glued and the two laminated Make one sheet, put it into the hot press, adjust the pressure of the hot press to 5kg / cm 2 , The hot pressing time is adjusted to 10 minutes / cm, and the temperature is controlled at 50-100℃; the hot press is pressed to make a standard door panel, and the standard door panel is placed for 15-20 days for health and balance, and the four sides are sawn off according to the specifications. Use 80# sand With fixed thickness sanding thickness, the thickness is 30-50mm.
