Embodiment Construction

[0039] (1) Collection of bamboo: The collection of bamboo needs to have clear records of bamboo species, collection location, collection time, collection quantity, collection person, bamboo age, diameter at breast height, length, and slight diameter;

[0040] (2) Visual classification of bamboo: classify the diameter, length, tip diameter, degree of curvature and defects of bamboo; the geometric shape of bamboo is hollow bamboo stalks divided by bamboo nodes, and the main geometric dimensions are: the length of bamboo stalks , diameter at breast height, number of bamboo nodes, spacing of bamboo nodes, long diameter of large and small ends of bamboo stalks; short diameter and thickness of bamboo wall, etc.

[0041] (3) Processing of bamboo strips (wool tops): The processing of wool tops is completed by a collider, which can be divided into equal pieces according to the average diameter of the bamboo stalks. The width of the tops is small, which is conducive to the uniformity of...

Abstract

The present invention belongs to the technical field of artifical boards and composite materials. The present invention applies the following processing steps: the collection of bamboo materials, the processing of bamboo culms, the slicing of bamboo strips, the processing of bamboo filament, the processing of a bamboo filament curtain, the glue dipping of the bamboo filament curtain, the glue trickling and drying of the glue-dipped bamboo filament curtain, the peeling and slicing of wood veneers, the removal of wood scars, the production of glulam, the glue dipping and drying of the wood veneers, unidirectional bamboo-wood laminating assembly, pressing, etc. By utilizing the characteristics of bamboo and wood and the performance complementation of bamboo as the main material and wood as the auxiliary material, a high-quality composite material with an excellent performance and without inside defects is produced.

Description

Technical field: [0001] The invention belongs to the technical field of wood-based panels and composite materials. Background technique: [0002] Bamboo is a renewable natural material with excellent performance, and the outer bamboo has good performance. However, the bamboo is thin-walled, hollow, and irregularly elliptical cone-shaped with a sharp point, and the radial properties of the bamboo are very different, and the external and internal properties of the bamboo are very different. Bamboo can be made into different processing units, including bamboo tubes, bamboo strips, bamboo slices (bamboo strips), bamboo filaments, vascular bundles and bamboo fibers. It is difficult to directly make high-performance structural materials from bamboo tubes. The main reason is that the geometric shape of the bamboo tube is irregular and the connection is difficult. The second is that the vascular bundles are densely distributed on the outside of the bamboo tube, and the dry shrink...
