Problems solved by technology

[0004] Its shortcoming is that the recombined bamboo glulam is pressed and solidified, so the fiber density is relatively high, mostly 1.1-1.3
Due to the high density, hard material, and large internal stress, the damage to the tool is serious during the sawing or planing process, and the bamboo reconstituted glulam slices are prone to cracking, resulting in waste products

Abstract

The invention discloses a method for manufacturing a bamboo recombined laminated wood sliced sheet. The method comprises the following steps of 1, raw material manufacturing, 2, drying treatment, 3, softening and expansion treatment, 4, drying treatment, 5, dipping treatment, 6, drying treatment, 7, pressing and curing, 8, softening treatment, 9, slicing processing and 10, drying treatment. The method has the advantages that bamboo recombined laminated wood can be softened, and the internal stress of the bamboo recombined laminated wood can be eliminated; in the slicing process, the cracking phenomenon of the bamboo recombined laminated wood sliced sheet can be completely eradicated, the use time of a slicing tool can be prolonged, and production cost can be lowered.

Description

technical field [0001] The invention relates to a method for preparing bamboo recombined glulam slices. Background technique [0002] Since the idea of ​​replacing wood with bamboo was put forward, people have given full play to their ingenuity and researched and produced bamboo recombined glulam slices, which are used for compounding on the surface of decorative panels, furniture panels, and floors, that is, it can reflect decorative panels, furniture panels, The characteristics of the natural bamboo material on the surface of the floor and the ability to save a large amount of bamboo raw materials have attracted a large number of scientific and technological personnel and entrepreneurs in this industry to research and develop it. [0003] The prior art of bamboo recombined glulam slicing is that bamboo shreds, bamboo strips, and bamboo slices are carbonized, dipped, pressed, and solidified into glulam, and then longitudinally sawed or sliced ​​into bamboo restructured glul...
