Abstract:
1. A method of manufacturing laminated bamboo sliver lumber, comprising steps of: a) preparing bamboo slivers, including: b) performing mothproofing, mildew proofing and antiseptic treatments to the bamboo slivers, then drying the bamboo slivers to a moisture content of about 6-15%; c) 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), then dehumidifying the machined bamboo slivers to a moisture content of about 3-10%; d) 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 e) 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 (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.
