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...
