Embodiment Construction

[0011] A best embodiment of the present invention: a, musical instrument wood is put into light wave processor and carry out electron irradiation 3 minutes; B, add the cellulase of 5 million u / ml, the α-amylase, 5 million u / ml neutral protease, 15 million u / ml β-amylase, 25 million u / ml xylanase, 2.5 million u / ml β-glucanase, 750 10,000 u / ml of pectinase and 10,000,000 u / ml of neutral lipase are prepared into an enzyme preparation solution; c, immerse the wood in the enzyme preparation solution for 20 minutes; d, put the soaked wood in a 50°C React in a constant temperature box for 48 hours; e, put the wood in water at 80°C-100°C for degreasing, desugaring and hydrolysis for 1 hour; f, take it out and put it in a drying oven at 60°C for 72 hours to dry. The treated wood is used as the main material of the violin's plate, sound beam, sound column, and piano bridge. The violin produced has achieved the effect of a new violin, with bright treble, deep bass, mellow timbre, and exc...

Abstract

A method for modifying wood by biologic and photoelectric techniques features that the biologic enzyme preparation is used to remove xylose from wood. said biologic enzyme preparation is prepared from cellulose, alpha-amylase, neutral proteinase, beta-amylase, xylanase, beta-glucanase, pectinase and neutral lipase. The modified wood can be used for music instrument.

Description

technical field [0001] The invention relates to a wood modification method, in particular to a treatment method for partially transforming substances in wood that affect the acoustic quality of musical instruments and sounding materials, and combining biological and photoelectric technologies for wood modification. Background technique [0002] At present, general wood modification adopts chemical treatment methods, such as soaking wood with resorcinol aqueous solution, air drying, and heating in formaldehyde vapor. This method improves the wood strength and dimensional stability, and reduces the hygroscopicity, but does not play a significant role in improving the timbre and sound quality of the musical instrument wood. The main reason is that this method introduces resin into the cellulose voids of the wood, and the weight and density of the wood after treatment increase. Production personnel and the environment have an impact, so it has not been widely promoted and appli...
