Embodiment 1
[0051] A method for producing an insect-proof multi-layer eucalyptus wood board, the production method of the multi-layer board includes veneer veneer sorting, veneer gluing, three times of cold pressing, three times of hot pressing, two times of static health preservation and dust scraping, sanding, repairing, The step of trimming and veneering is characterized in that before the first cold pressing, trimming, the first hot pressing and the last hot pressing, a layer of insect-proof curing film is sprayed around and up and down the surface of the slab to protect and prevent The glue dries too quickly during the hot pressing process and maintains the internal stress of the multi-layer board. It can also make the urea-formaldehyde glue fully react, so that the formed multi-layer board has high strength and insect resistance; the user reduces volatile formaldehyde during use. After the third hot pressing, the boards are left to stand for health preservation, sanded and veneered, ...
Embodiment 2
[0060] A method for producing an insect-proof multi-layer eucalyptus wood board, the production method of the multi-layer board includes veneer veneer sorting, veneer gluing, three times of cold pressing, three times of hot pressing, two times of static health preservation and dust scraping, sanding, repairing, The step of trimming and veneering is characterized in that before the first cold pressing, trimming, the first hot pressing and the last hot pressing, a layer of insect-proof curing film is sprayed around and up and down the surface of the slab to protect and prevent The glue dries too quickly during the hot pressing process and maintains the internal stress of the multilayer board. It can also make the urea-formaldehyde glue fully react, so that the strength of the multilayer board after molding is high, and the volatile formaldehyde is reduced during the user's use. The third After the first hot pressing, the boards are left to stand for health preservation, sanded an...
