Fabrication method of bamboo sounding material

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...

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 requires manual search and testing of wood materials suitable for each sound area, which is not suitable for industrial production, and its production process cannot achieve effective control of industrial technical parameters

[0006] Therefore, the bamboo materials made by ordinary carbonized bamboo technology and recombined bamboo technology are not suitable for use as the sounding materials of bamboo musical instruments, and the wood materials used in the traditional production of xylophone soundboards cannot reach the purpose of industrial production.
