  • Patent number: 8231757
    Abstract: A method of manufacturing laminated bamboo sliver lumber comprises steps of: preparing bamboo slivers; performing moth-proofing, mildew-proofing, and antiseptic treatments to the bamboo slivers and then drying the bamboo slivers to a moisture content of about 6-15%; machining each dried bamboo sliver to a thickness of about 0.5-3.5 mm (0.02-0.14 in) and a width of about 5-22 mm (0.20-0.87 in) and then dehumidifying the machined bamboo slivers to a moisture content of about 3-10%; applying a glue to the bamboo slivers by glue-coating or “immerging” process, in which a ratio of the glue to an absolute dry weight of the bamboo slivers is about 3-16%; and arranging the glued bamboo slivers with their “width” direction consistent with the “vertical” direction and then pressing the arranged bamboo slivers and curing the glue under a “side” pressure of about 3-15 MPa (0.44-2.18 ksi) and a “top” pressure of about 1-6 MPa (0.15-0.87 ksi) so as to form the laminated bamboo sliver lumber.

  • Publication number: 20100258243
    Abstract: A method of manufacturing laminated bamboo sliver lumber, comprising steps of: selecting and using the bamboo outer slivers obtained from a bamboo and having an air dry density no less than about 0.95 g/cm3 and removing siliceous and wax layers thereon to obtain bamboo slivers having a width of about 1-4 mm. Drying the bamboo slivers to a moisture content of about 6-15%, machining the dried bamboo slivers to a thickness of about 0.5-3.5 mm and a width of about 5-22 mm, then dehumidifying the bamboo slivers to a moisture content of about 3-10%. Applying a glue to the bamboo slivers in which a ratio of the glue to an absolute dry weight of the bamboo slivers may be about 3-16%. A arranging the glued bamboo slivers with their width direction consistent with the vertical direction, then pressing the arranged bamboo slivers and curing the glue under a side pressure of about 3-15 MPa and a top pressure of about 1-6 MPa.
