Problems solved by technology

At the same time, people are paying more and more attention to the pollution caused by the coloring of wood products. That is, wood products need colorants to be colored, and colorants will emit harmful gases such as formaldehyde, which will have harmful effects on the human body. It has a strong stimulating effect on the skin and mucous membranes, and it will also lead to a decrease in immunity, which will cause great harm to people's health.
Although wood products with high content of formaldehyde and other harmful gases have been banned by the country, due to the processing characteristics of wood products, existing wood products on the market will still contain a certain amount of formaldehyde and other harmful gases, and the manufacture of such products contains a certain amount of The cost of wood products with harmful gases such as formaldehyde is higher

Embodiment 1

[0029] Example 1. A method for microbial fermentation of colored wood, comprising the following steps:

[0030] ① Cook the whole grains with obvious color and starch, and then cool to room temperature to obtain product A;

[0031] ② Chop product A into a puree, then add white vinegar brewed from grain, filtered water soaked in plant ash, alcoholic yeast (such as Maifuqu) and mix until uniform, and then get product B; the white vinegar is 7-8 times the amount of product A. Add in multiples; soak the filtered water of plant ash, add in 1% to 2% of the quality of product A; add alcoholic yeast in 0.4% to 0.5% of the quality of product A;

[0032] ③ Put product B into a clean container (such as a ceramic jar, glass jar or high-strength plastic jar) for sealing, and then place it in a place with an ambient temperature of 0°C to 60°C for 24 to 28 hours to obtain product C, which can also be extended The longer the placement time, the better the effect will be, but the cost will al...

Embodiment 2

[0037] Example 2. A method for microbial fermentation of colored wood, the following steps can be used:

[0038] ① Cook the whole grains with obvious color and starch, and then cool to room temperature to obtain product A;

[0039] ② Chop product A into a puree, then add white vinegar brewed from grain, edible alkali, and alcoholic yeast and mix until evenly to obtain product B; among them, white vinegar is added at 6 to 7 times the amount of product A; edible alkali is mixed with A 1% to 2% of the quality of product A is added; alcoholic yeast is added at 0.2% to 0.3% of the quality of product A;

[0040] ③ Put product B into a clean container (such as a ceramic jar, glass jar or high-strength plastic jar) for sealing, and then place it in a place with an ambient temperature of 0°C to 60°C for 24 to 28 hours to obtain product C, which can also be extended The longer the placement time, the better the effect will be, but the cost will also increase;

Abstract

The invention discloses a method for coloring wood by fermenting microorganisms, which is characterized by comprising the following steps: thoroughly cooking whole grains and cooling to room temperature; adding white vinegar, dietary alkali or soaking filtering water of plant ash and alcohol yeast for mixing and stirring to be uniform; placing the mixture into a clean container for sealing and then placing at a place the ambient temperature of which is 0-60DEG C for over 24 hours; deslagging and filtering to obtain fermentation liquor; coating the fermentation liquor on a coloring surface of the wood; sealing and wrapping with a thin film or an agricultural film for fermentation; placing the wood at a place the ambient temperature of which is 0-80DEG C; and coloring after fermenting for over 2 hours. All raw materials used by the invention are nuisanceless; the wood can be colored under the action of fermenting the microorganisms on the wood without volatile organic solvent and toxic compound; harmful gases cannot be generated during use; and in addition, the invention can prevent the environmental pollution and ensure the health of people and has lower production cost.

Description

technical field [0001] The invention relates to a method for coloring wood, in particular to a method for coloring wood by microbial fermentation. Background technique [0002] At present, with the gradual improvement of living standards, people's tastes for living and office environments and decoration are also constantly improving. In home decoration, they are more interested in healthy and environmentally friendly building materials while pursuing beauty. The use of wood products both indoors and outdoors is becoming more and more common. At the same time, people are paying more and more attention to the pollution caused by the coloring of wood products. That is, wood products need colorants to be colored, and colorants will emit harmful gases such as formaldehyde, which will have harmful effects on the human body. It has a strong stimulating effect on the skin and mucous membranes of the human body, and can also lead to a decline in immunity, thereby causing great harm ...
