Abstract

Plywood for a bamboo-wood composite container baseplate is formed by subjecting multiple layers of bamboo plates and wood plates to combining, prepressing and hot-press gluing. The plywood sequentially comprises an upper face layer, a lower face layer, a veneer layer, a middle layer, another veneer layer and another lower face layer, each of the upper face layer and the lower face layers is composed of two layers of longitudinal wood veneer and one layer of bamboo veneer, the middle layer is composed of two or three layers of longitudinal wood veneer and three or two layers of horizontal bamboo veneer, and each veneer layer is composed of three layers of horizontal wood veneer and two layers of longitudinal bamboo veneer. During assembly of the composite baseplate, the upper face layer, the middle layer and the lower face layers are assembled firstly, and assembly is performed on a production line after prepressing, so that the defects of proneness to disorder of assembly level and high manual operation requirement are overcome; in the process of hot pressing, a cold-in cold-out process is adopted, so that the defect that the surface of the container baseplate is prone to unevenness and warping due to bamboo characteristics is overcome, tensile performance and flexural performance of bamboo are brought into good play, and quality requirements of the container baseplate are guaranteed.
