Embodiment Construction

[0022] Below in conjunction with embodiment this law is described in detail:

[0023] 1. Method

[0024] ①The first stage of fermentation

[0025] The preparation method of described lactic acid bacteria-saccharomyces fermented liquid:

[0026] A. Culture medium preparation

[0027] Weigh 200g of polyvalent peptone, 10g of tryptone, 5g of yeast extract, 5g of sodium chloride, 50g of beef extract, 0.4g of cysteine, 5g of hemin, and 676mL of beef extract, and adjust the pH value to 7.4 after mixing. 121°C damp heat sterilization for 30 minutes;

[0028] B, preparation of Lactobacillus bulgaricus liquid

[0029] Inoculate Lactobacillus bulgaricus delbrueckii into the above medium at a ratio of 5-10% of the mass of the medium, and culture it anaerobically at 28-38°C for 48 hours to obtain Lactobacillus bulgaricus delbrueckii liquid;

Abstract

The invention discloses a man-made ebony production method and relates to a wood modifying technology. The method comprises the steps of carrying out first-stage fermentation, namely arranging special wood in lactic acid bacteria-yeast fermentation liquor so as to completely soften wood fiber and communicate intervals of cell walls; carrying out second-stage fermentation, namely after methane bacteria generated by fermentation enters the inner part of wood, carrying out anaerobic fermentation on biogas gas to generate methane gas; heating and pressurizing for catalysis, namely generating gas phase carbon by methane gas residual at the inner part of wood, and depositing the gas phase carbon on the wood fiber so as to obtain the man-made ebony. According to the method, most part of wood fiber is carbonized to be modified; the color and luster of the processed wood are similar to the color and luster of natural ebony; the index of the man-made ebony is similar to the materialization index of the natural ebony; the method is suitable for the modification of wood such as phoeba bournei, toona ciliata roem., camphorwood and pterocarya stenoptera.

Description

technical field [0001] The invention relates to a wood modification technology, in particular to a production method of artificial ebony. Background technique [0002] Ebony, also known as gloomy wood, is formed by the long-term carbonization process of trees such as Phoebe, Red Toon, Camphor and Willow buried in mud due to natural disasters. Its formation time is about 3000-8000 Years vary. The essence of ebony is hard, mostly brownish black, black red, gold and yellowish brown, with smooth cut surface and fine wood grain, which can be polished to make the surface as bright as a mirror; the essence of some ebony is similar to red sandalwood. It never fades, does not decay and does not live in insects. It is an ideal material for making artworks and antique furniture. Some natural shaped ebony artworks are extremely valuable for collection. [0003] Since ebony is a non-renewable resource, the amount of development is less and less, and no material that can completely repl...
