Problems solved by technology

[0005] The recombined bamboo produced by the existing recombined bamboo processing method has a certain size and length, and it is difficult to meet the needs of different lengths. Although there is also a process of using a continuous press to produce a heat-pressed recombined bamboo of a specified length, this process has high manufacturing costs and difficult production. Large, general production efficiency and other defects

[0036] Preparation / drying / dipping of bamboo curtain in step a:

[0037] The woven bamboo screen is dried at 100°C, and the moisture content is controlled at 6%. The choice of temperature depends on different materials and ambient temperature, but if the temperature is too high, it will be carbonized and affect the mechanical strength, while if it is too low, it will affect the drying efficiency.

[0038] The adhesive is phenolic resin or other adhesives with equivalent properties, the dipping amount is 10%, the percentage is the ratio of the absolute dry weight of the resin to the absolute dry weight of the bamboo unit; and dried or aged to a moisture content of 10-15%.

[0039] Step b metering billets

[0040] Measure the weight and the number of layers of the bamboo curtain dipped and dried according to the thickness. Pave according to the folding method, make the length direction of the bamboo bundle parallel to the length direction of the mould;

Abstract

The invention relates to a rolled recombined bamboo profile of specified length and a manufacturing method thereof. The manufacturing method comprises the steps of a) bamboo curtain splint knitting / drying / impregnation; b) weighing and assembling; c) performing and assembling; d) blank manufacturing through mold pressing; and e) heating and curing. Loose bamboo chips of fixed width and fixed thickness are adopted to be knitted into a whole bamboo curtain splint of the specified length, the bamboo curtain splint is rolled or cut off, the direction of part or all of bamboo fibers is parallel to the a mold for assembling, pressing is carried out firstly, then mold sleeving is carried out, and in addition, curing is carried out in curing equipment, and the recombined bamboo profile is formed. By means of the process, the existing recombined bamboo pressing technology is improved, the recombined bamboo profile of the specified length can be obtained, the percentage of outturn can be increased if the recombined bamboo profile serves as a building structure material, automatic continuous production is promoted, and great help is provided for production efficiency improving.

Description

technical field [0001] The invention relates to the technical field of recombined bamboo and wood processing, in particular to a structural bamboo (wood) material, and relates to a processing and manufacturing method of recombined bamboo profiles. Background technique [0002] my country is the country with the most abundant bamboo resources in the world. In recent years, with the shortage of timber resources in the world, it is becoming more and more important to use timber and bamboo resources rationally and effectively. [0003] In the prior art, the main recombined bamboo technologies used in the fields of construction and decoration are: (1) Bamboo raft recombination technology: the bamboo material is processed into thick bamboo sloughs, alone, or combined with combed wood bundles, Appropriate amount of veneer strips are dried to a moisture content of 8-15% and glued with phenolic resin. (2) Bamboo fiber-reinforced composite material manufacturing technology: The bamb...
