Embodiment 1

[0034] A kind of method utilizing discarded bamboo chopsticks to manufacture high-performance bamboo plate, comprises the following steps:

[0035] Quantitative softening treatment of bamboo chopsticks: the bamboo chopsticks are made of 5% Ca(OH) 2 The solution is soaked at room temperature for 24 hours to remove a certain amount of lignin, and obtain bamboo chopsticks in a saturated state from which part of the extract and lignin have been removed. The bending performance of bamboo chopsticks is 115MPa.

[0036] Bamboo chopsticks rolling and decompression treatment: bamboo chopsticks decompression and decompression treatment: through the rolling and decompression equipment, the softened bamboo chopsticks are decomposed into bamboo bundles with a width of 10mm (tensile performance 120-160MPa), and dried to a moisture content of 15% , wherein, the gap between the rolls of the rolling and decomposing equipment is 0.5mm, and the number of rolling is 1 time;

Embodiment 2

[0041] A kind of method utilizing discarded bamboo chopsticks to manufacture high-performance bamboo plate, comprises the following steps:

[0042] Quantitative softening treatment of bamboo chopsticks: immerse waste bamboo chopsticks in Ca(OH) with a mass fraction of 2% at a temperature of 100°C 2 In the solution, boil for 8 hours to remove a certain amount of lignin, and obtain bamboo chopsticks that remove part of the extract and lignin in a saturated state, and the bending performance of the bamboo chopsticks is 92MPa;

[0043]Bamboo chopsticks rolling and decompression treatment: the softened bamboo chopsticks are decomposed into bamboo bundles with a width of 12mm (tensile property 70-90MPa) by rolling and decompression equipment, and dried to a moisture content of 15%;

[0044] Among them, the rolling and decompression process is: rolling once with a gap of 2.0mm between the rollers, once rolling with a gap of 1.5mm, and once rolling with a gap of 1mm, a total of 3 time...

Embodiment 3

[0050] A kind of method utilizing discarded bamboo chopsticks to manufacture high-performance bamboo plate, comprises the following steps:

[0051] Quantitative softening treatment of bamboo chopsticks: boil bamboo chopsticks in boiling water at 100°C for 24 hours to remove certain lignin, and obtain bamboo chopsticks with partial extract and lignin removed in a saturated state; the bending performance of bamboo chopsticks is 145MPa;

[0052] Bamboo chopsticks rolling and decompression treatment: the softened bamboo chopsticks are decomposed into bamboo bundles with a width of 15mm (tensile property 40-60MPa) through the rolling and decompression equipment, and dried to a moisture content of 15%; wherein, the rolling and decompression equipment The gap between the rollers is 1mm, and the rolling times are 3 times;

[0053] Panel lengthening treatment: Bamboo bundles are impregnated with a thermosetting phenolic resin adhesive, with an adhesive amount of about 20%, dried to a m...

Abstract

The invention discloses a method for manufacturing high-performance bamboo plates through waste bamboo chopsticks. The method comprises the steps that the bamboo chopsticks are subjected to earlier-stage pretreatment through strong base or the high-temperature steaming technology, on one hand, the effects of disinfection and sterilization are achieved, and on the other hand, the bamboo chopsticksare softened to facilitate later-stage processing and utilization; by means of the rolling and brooming technology, the bamboo chopsticks are processed to be loose bamboo bundles, and the defect thatthe original size of the bamboo chopsticks is not uniform is reduced; and finally, by means of the lengthening technology, the bamboo chopsticks are manufactured into the bamboo plates with differentlengths, and the bamboo plates can be directly used for manufacturing bamboo floors or compounded with poplar veneers or bamboo veneers to manufacture bamboo decoration plates and the like. The platesprovide a new way for solving the pollution problem and the reuse problem of waste bamboo chopsticks, and have the good application prospect.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a method for manufacturing high-performance bamboo boards by utilizing waste bamboo chopsticks. Background technique [0002] my country is a big consumer of bamboo chopsticks. It consumes nearly 45 billion pairs of disposable chopsticks every year, most of which are bamboo chopsticks. However, there are very few ways to reuse waste bamboo chopsticks after use. Only a small amount of chopsticks are recycled for pulp and paper making in China. The technical difficulty of using waste bamboo chopsticks to manufacture high-performance bamboo boards lies in the low moisture content of bamboo chopsticks products, which cannot be directly broomed, and the size is limited, and the production of products needs to solve the problem of lengthening. [0003] The softening treatment of discarded bamboo chopsticks can not only increase the moisture content, separate the parenchyma cells and...
