Directional staggered bamboo reed filament plate and manufacturing method thereof

Abstract

The invention belongs to the technical field of preparation of bamboo reed filament plates, and discloses a directionally staggered bamboo reed filament plate and a manufacturing method thereof. The manufacturing method of the directionally staggered bamboo reed filament plate comprises the following steps: selecting and picking upright and tough bamboo reeds with thick and large stems and multiple sections, and preparing bamboo reed filaments by using the picked bamboo reeds; treating the prepared bamboo reed filaments to obtain the bamboo reed filaments for staggered weaving; assembling and pre-pressing the bamboo reed filaments; and hot pressing the pre-pressed bamboo reed filament plate, and cleaning the bamboo reed filament plate subjected to hot pressing to obtain the directionally-staggered bamboo reed filament plate. The bamboo reed filament plate provided by the invention is manufactured by adopting the bamboo reed filaments and an adhesive through a directional staggering method, so that the defect of low strength of reconstituted bamboo wood in the transverse direction is overcome, and the dimensional stability and the physical and mechanical properties are improved. The bamboo reed filaments are quantified in length, width and thickness in the manufacturing process, the problem that gluing is difficult is solved, the using amount of the adhesive is small, and the pressed bamboo reed filament plate is uniform in density distribution, small in density and easy to carry and decorate.

Description

technical field [0001] The invention belongs to the technical field of preparation of reed bamboo silk board, in particular to an orientation interlaced reed bamboo silk board and a manufacturing method thereof. Background technique [0002] At present, reed reed, also known as Dilu bamboo, river reed, dryland reed, is a perennial herbaceous plant with a wide range of distribution and strong adaptability. The stem is erect and straight, and the leaves are broad and bright green. Luzhu is mainly distributed in Jiangsu, Zhejiang, Hunan, Shandong, Guangxi and other regions. Reed bamboo is both drought and waterlogging tolerant, both heat and cold tolerant, and it can still take root and sprout in poor soil. The growth cycle of reed bamboo is short, usually two or three seasons a year, and the yield per mu is relatively high, up to 10 tons of dry material per mu, which is much higher than that of bamboo. Therefore, reed bamboo has the characteristics of rich resources and hig...

Problems solved by technology

[0003] Since the material properties of Arundos reeds are similar to those of bamboo: it has the characteristics of high longitudinal strength and low transverse strength, it can be used instead of bamboo to produce high-performance wood-based panels, but there is no public report on the use of Arundis to produce wood-based panels

Recombined bamboo is a kind of bamboo wood-based panel with excellent performance. There have been many researches and applications of recombined bamboo. The traditional production process of recombined bamboo adopts processes such as degreening treatment, dipping treatment and molding treatment. There are disadvantages such as large amount of adhesive, high production cost, and high product density; and because of the small diameter of the reed bamboo stalk, it is difficult to process it into sheets, and it is difficult to directly apply the traditional recombinant bamboo production technology to the production of high-performance reed bamboo wood-based panels.

[0004] Through the above analysis, the problems and defects of the existing technology are: the existing recombined bamboo production process is complicated, the cost is high, and it is difficult to realize popularization and use; and the recombined bamboo product has a high density and a large amount of glue, which is not suitable for the use of wood-based panels. need
