A kind of wood bleaching method
A technology for wood and treatment tanks, applied in the field of wood bleaching, can solve the problems of increasing the ability to decompose lignin, easily irritating the mucous membranes of the respiratory tract, and reducing the decomposition of cellulose, so as to improve the ability to inhibit photochromic, good bleaching effect, and less corrosive.

Examples
example 1
[0017] First put the wood into the treatment tank, add a mass fraction of 8% sodium bicarbonate solution to the treatment tank until it completely submerges the wood by 4cm, let it stand for 7 hours, then heat the treatment tank until the liquid in the treatment tank boils and maintain the temperature 10min, then take out the wood in the treatment pond while it is hot, and carry out natural drying. When the moisture content in the wood is 20%, collect the wood after drying for subsequent use; then, take 40 parts of agar and 30 parts of yeast Extract, 70 parts of distilled water, 18 parts of sucrose, 12 parts of corn flour, 7 parts of lignin, 2 parts of dipotassium hydrogen phosphate, 1 part of potassium dihydrogen phosphate and 0.8 parts of magnesium sulfate, stir evenly, and put into a sterilizing pot Sterilize to obtain a liquid medium; then inoculate puffballs into the above liquid medium according to the inoculum size of 12%, then place the liquid medium in a shaking incuba...
example 2
[0020] First put the wood into the treatment tank, add a mass fraction of 8% sodium bicarbonate solution to the treatment tank until it completely submerges the wood by 5cm, let it stand for 8 hours, then heat the treatment tank until the liquid in the treatment tank boils and maintain the temperature 13min, then take out the wood in the treatment pond while it is hot, and carry out natural drying. When the moisture content in the wood is 23%, collect the wood after drying for subsequent use; then count 43 parts of agar and 33 parts of yeast Extract, 75 parts of distilled water, 20 parts of sucrose, 14 parts of corn flour, 8 parts of lignin, 3 parts of dipotassium hydrogen phosphate, 2 parts of potassium dihydrogen phosphate and 1.2 parts of magnesium sulfate, stir evenly, and put into a sterilizing pot Sterilize to obtain a liquid medium; then inoculate puffballs into the above liquid medium according to the inoculum size of 15%, then place the liquid medium in a shaking incub...
example 3
[0023]First put the wood into the treatment pool, add a mass fraction of 8% sodium bicarbonate solution into the treatment pool until the wood is completely submerged by 6cm, let it stand for 8 hours, then heat the treatment pool until the liquid in the treatment pool boils and maintain the temperature 15min, then take out the wood in the treatment pond while it is hot, and carry out natural drying. When the moisture content in the wood is 25%, collect the wood after drying for subsequent use; then, take 45 parts of agar and 35 parts of yeast Extract, 80 parts of distilled water, 22 parts of sucrose, 16 parts of corn flour, 9 parts of lignin, 4 parts of dipotassium hydrogen phosphate, 3 parts of potassium dihydrogen phosphate and 1.4 parts of magnesium sulfate, stir evenly, and put into a sterilizing pot Sterilize to obtain a liquid medium; then inoculate puffballs to the above liquid medium according to the inoculum size of 17%, then place the liquid medium in a shaking incuba...
