Problems solved by technology

However, the bamboo fiber of this kind of board has been broken by high temperature, and the fiber holes have been blocked by glue and compacted. The board does not have activity and toughness. There will be dimensional deformation, surface cracking, warping, unevenness, etc.
[0005] The sound board used in the xylophone is made of wood materials with soft texture, wide pronunciation, low sound range and long reverberation, such as the marimba. Under the traditional technology, when making the sound board, each piece of wood material is Manual screening

Example Embodiment

[0045] Example 1:

[0046] (1) Broken bamboo, choose bamboo material with a bamboo age of 4-6 years, and cut the bamboo material. The length of the broken bamboo is 300mm. (2) Split the broken bamboo into slices. The width of the sliced ​​bamboo is 18mm, and the width tolerance is controlled within ±1mm. (3) Rough planing to leave green. The bamboo slices cut in the previous step are roughly planed to leave green. The thickness of the bamboo slices is 6.5mm, the green retention rate is 25%, and the thickness tolerance is controlled within ±1mm. (4) The bamboo slices after rough planing and leaving green in the previous step are loaded into the heating kiln and stacked in layers. Each layer is separated by spacers. The spacers can be stainless steel square steel or rectangular steel. Uniform, the spacers of each layer are aligned at the height of the stack, and the gaps separated by the spacers on each layer are uniform ventilation air passages. (5) Increase the temperature, gra...

Abstract

The invention discloses a fabrication method of a bamboo sounding material, which comprises the following steps: (1) bamboo breaking, (2) splitting, (3) rough planing and green skin remaining, (4) kiln loading and stacking, (5) heating, (6) humidifying, (7) high-temperature pyrolysis, (8) humidity conditioning and cooling, (9) kiln discharge, and (10) balancing and curing. The fabrication method of the bamboo sounding material has the characteristics of reasonable process, high production efficiency, short production cycle, low energy consumption, no environmental pollution and high greenwood utilization ratio; the produced bamboo has the characteristics of stable product performance, higher density, high strength, high hardness, high toughness and stable moisture content; and the fabrication method is suitable for the bamboo instrument sounding material.

Description

technical field [0001] The invention relates to the technical field of bamboo material processing, in particular to the manufacture of sounding materials for bamboo musical instruments, which are suitable for making percussion bamboo musical instruments. Background technique [0002] The main parameters to measure the quality of bamboo musical instrument materials are tone, loudness and timbre. The quality of its performance mainly depends on the broad density, equilibrium moisture content, elastic modulus, compactness of bamboo internal structure and fiber pores of bamboo material. how much. [0003] Ordinary carbonized bamboo technology is a method to change the color of bamboo under high temperature and high humidity conditions. It destroys and removes the nutrients in bamboo, but it cannot destroy the water-absorbing hydroxyl functional groups in bamboo cells. Therefore, the carbonized bamboo chips The moisture content in the atmosphere is unstable, resulting in unstabl...
