Embodiment three: thin bamboo strips used for weaving being immersed concentration is in the inorganic salt solution of 20%, 10 hours; Temperature remains on 50 DEG C; Inorganic salt solution pH value is 9; Insert again in centrifugal barrel, heat to 340 DEG C, 600 turns per minute, keep 4 minutes.
13), bamboo bits processing, the waste bamboo glue supporting plate of recovery or the waste utilization pulverizer of bamboo processing are processed as needle-like or corynebacterium, and length is 5-35mm, width is 0.2-2.0mm, and thickness is 0.1-2.5mm, stand-by;
14), discarded bamboo glue supporting plate is carried out clean and after drying and processing, obtained sectional dimension is the regeneration bamboo cane of 5-12 × 5-12mm, stand-by;
2), wear-resistant coat base unit preparation:
21), bamboo mat preparation, by step 11) in the obtained blue or green thin bamboo strip be processed as bamboo mat;
22), bamboo curtain splint preparation, by step 12) in obtained be processed as bamboo curtain splint without drop thin bamboo strips used for weaving;
3), assembly is shaping:
31), first lay successively as wear-resistant coat bamboo mat, strengthen mesh sheet and bamboo curtain splint;
32), sandwich layer is laid;
33), lay successively again on sandwich layer as wear-resistant coat bamboo curtain splint, strengthen mesh sheet and bamboo mat;
34), hot pressing and displaying: after hot press pressurization, heat treatment, form slab, then flat heap is displayed;
35), processing process; Cut into the regeneration bamboo glue supporting plate base of given size, then through corner process, obtained regeneration bamboo glue supporting plate.
Step 32) laying sandwich layer be: by step 14 on the bamboo curtain splint of wear-resistant coat) obtained regeneration bamboo cane is intersected and is placed, then spreading consider containing the bamboo of 15%-20% parts by weight of phenolic resin glue, finally obtains the bamboo glue supporting plate that thickness is 10-50mm.
