Embodiment 1
[0022] Embodiment 1 This embodiment discloses a method for preparing a biomass board, the method is as follows:
[0023] S1. Straw fiber preparation: Use a straw fiber pulverizer to process the dried straw into straw fibers with a particle size of 5mm-50mm. (Straw fiber is at least one of corn straw, wheat straw, rice straw, soybean straw, and bagasse ); Among them, the proportion of straw fibers with a particle size of 5mm-20mm and 20mm-50mm are 65% and 35% respectively;
[0024] S2. Sterilization: add 15% rice bran of the dry weight of the straw to the straw fiber, and after mixing, add an aqueous solution of 1.5% quicklime and 1% gypsum powder to the straw fiber until the straw fiber absorbs water and reaches saturation. When the amount of water reaches 60%, the material is sterilized by a steam autoclave (pressure is 0.12Mpa, time is 1.4h).
[0025] S3. Preparation of fungal mycelium: Fill the sterilized mold with the cooled sterilized material until it is half the depth of the ...
Embodiment 2
[0030] Embodiment 2 This embodiment discloses a method for preparing a biomass board, the method is as follows:
[0031] S1. Straw fiber preparation: Use a straw fiber pulverizer to process the dried straw into straw fibers with a particle size of 5mm-50mm. (Straw fiber is at least one of corn straw, wheat straw, rice straw, soybean straw, and bagasse ); Among them, the proportions of straw fibers with a particle size of 5mm-20mm and 20mm-50mm are 55% and 45% respectively;
[0032] S2. Sterilization: Add 11% rice bran of the dry weight of the straw to the straw fiber. After mixing, add an aqueous solution of 1.7% quicklime and 0.6% gypsum powder to the straw fiber until the straw fiber reaches saturation. When the water content reaches 56%, the material is sterilized with a steam-type autoclave (pressure is 0.14Mpa, time is 1.2h).
[0033] S3. Preparation of fungal mycelium: Fill the sterilized mold with the cooled sterilized material until it is half the depth of the mold, then spr...
Embodiment 3
[0038] Embodiment 3 This embodiment discloses a method for preparing a biomass board, the method is as follows:
[0039] S1. Straw fiber preparation: Use a straw fiber pulverizer to process the dried straw into straw fibers with a particle size of 5mm-50mm. (Straw fiber is at least one of corn straw, wheat straw, rice straw, soybean straw, and bagasse ); Among them, the proportion of straw fibers with a particle size of 5mm-20mm and 20mm-50mm are 75% and 25% respectively;
[0040] S2. Sterilization: Add 23% rice bran of the dry weight of the straw to the straw fiber. After mixing, add an aqueous solution of 1.2% quicklime and 1.4% gypsum powder to the straw fiber until the straw fiber is saturated with water. When the amount of water reaches 64%, the material is sterilized by a steam-type autoclave (pressure is 0.07Mpa, time is 1.6h).
[0041] S3. Preparation of fungal mycelium: Fill the sterilized mold with the cooled sterilized material until it is half the depth of the mold, then...
