Embodiment 1
[0030] A method for manufacturing an environment-friendly home improvement building material board by using chrysanthemum stalks and birch shavings, comprising the following steps:
[0031] (1) After drying the chrysanthemum stalks, pulverize them through an 80-mesh sieve with a pulverizer, immerse them in a sodium hydroxide solution with a mass concentration of 1.2% for 8 hours, take them out and drain them, and then immerse them in an acetic acid solution with a mass concentration of 1% for 4.5 hours. After drying until the water content is 16%, it is added to the gas explosion device through the feed port, and the water vapor at 185°C enters the gas explosion device from the steam pipe, pressurized to 7MPa, kept for 3 minutes after heat preservation and pressure release, and exploded to obtain Chrysanthemum chrysanthemum Powder;
[0032] (2) Grind the birch wood shavings to a length of 1-2mm and a width of 0.1-0.5mm. At room temperature, first soak them in a hydrogen peroxi...
Embodiment 2
[0036] A method for manufacturing an environment-friendly home improvement building material board by using chrysanthemum stalks and birch shavings, comprising the following steps:
[0037] (1) After drying the chrysanthemum stalks, crush them through an 80-mesh sieve with a pulverizer, immerse them in a sodium hydroxide solution with a mass concentration of 0.5% for 10 hours, take them out and drain them, and then immerse them in an acetic acid solution with a mass concentration of 1.2% for 6 hours, and let them air naturally After drying until the water content is 15%, it is added into the gas explosion device through the feed port, and the water vapor at 180°C enters the gas explosion device through the steam pipe, pressurized to 8MPa, kept at the pressure for 3 minutes, and then released and exploded to obtain yellow top inulin body;
[0038] (2) Grind the birch shavings to a length of 1-2 mm and a width of 0.1-0.5 mm. At room temperature, first soak them in a hydrogen per...

[0042] A method for manufacturing an environment-friendly home improvement building material board by using chrysanthemum stalks and birch shavings, comprising the following steps:
[0043] (1) After drying the chrysanthemum stalks, pulverize them through an 80-mesh sieve with a pulverizer, immerse them in a 0.8% sodium hydroxide solution for 5 hours, take them out and drain them, and then immerse them in a 1.1% acetic acid solution for 5.5 hours. After drying until the water content is 18%, it is added into the gas explosion device through the feed port, and the water vapor at 180°C enters the gas explosion device from the steam pipe, pressurized to 6.5MPa, kept for 3 minutes after heat preservation and pressure release, and exploded to obtain Yellow top chrysanthemum powder;
[0044] (2) Grind the birch shavings to a length of 1-2 mm and a width of 0.1-0.5 mm. At room temperature, first soak them in a hydrogen peroxide solution with a mass concentration of 15% for 2 hours, a...
