Embodiment Construction

[0014] The manufacturing process of super-long (the length specification of the profile is 5 meters) bamboo-wood composite profile is as follows:

[0015] Raw material processing: Cut out 5.2-meter-long ultra-long bamboo sections, split them radially into bamboo strips, and remove bamboo green and bamboo bones.

[0016] Degreasing, rolling drying, spraying glue, aging: degreasing (ie heat treatment) is soaking chemical raw materials in high temperature water, softening and degreasing treatment, in order to achieve the purpose of softening, anti-corrosion, and mildew prevention; rolling is to press the raw materials into unequal cracks The green sheet has a thickness of 0.3-0.4cm and a width of 1.7-2.0cm, and is dried so that the moisture content of the bamboo strips is controlled at 8-12%; 30-32%, the amount of dipping is 20-22%, and the surface of the slab is impregnated with preservatives; aging refers to placing the raw materials after gluing for a period of time to make th...

Abstract

The present invention discloses a production method of an ultra-long bamboo-wood composite sectional material. Mostly, the length of the prior bamboo veneer is less than three meters and therefore cannot satisfy the requirements of certain exceptional cases. According to the length of the sectional material plus finishing allowance, the production method cuts an ultra-long bamboo section, which is then ripped into sawali strips; bamboo green and bamboo rib skin are removed; after undergoing degreasing, rolling and drying, glue bathing and aging, the sawali strips are loaded into a mould to bepressed. The production method is characterized in that before the sawali strips are loaded into the mould, the quantity and the water ratio of the sawali strips are determined, the material is prepressed before receiving mould pressing, the sawali strips are evenly and symmetrically arranged in the mould, and pore spaces among the sawali strips are filled with short bamboo filaments and wood chips. While reducing the density of bamboo material, the production method does not degrade the owned properties of the bamboo material. The production method, which is widely applicable to certain exceptional cases, can produce a bamboo-wood composite sectional material which is more than four meters long.

Description

technical field [0001] The invention relates to imitation wood boards for construction, in particular to a method for manufacturing super-long bamboo-wood composite profiles. Background technique [0002] With the development of the bamboo plywood industry, bamboo plywood has been widely used in some bridges and building templates of high-rise buildings, and bamboo curtains, bamboo floors, bamboo mats, etc. have also been used in home decoration. Existing methods for processing bamboo into bamboo plywood are many, and the length of the bamboo plywood obtained by it is mostly below 3 meters, while house beams, ship decks, park gazebos, small wooden bridges, etc. need to use more than 12cm in diameter and more than 4 meters in length. , the bamboo plywood that existing method obtains can't satisfy above-mentioned market demand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manufacturing method of super-long...
