Embodiment 1
[0033] Under the conditions of normal temperature and pressure, take carboxybetaine (x=11, n=6), prepare the carboxybetaine solution of 0.5% concentration, add rice husk according to the mass ratio of carboxybetaine and rice husk-derived carbon particles 50:1 The carbon particles are derived and mixed to obtain a foam release agent composition.
[0034] The preparation method of rice husk-derived carbon particles of this embodiment: the naturally air-dried rice husks are placed in a tube furnace, and the 2 The temperature was raised to 700°C under protective conditions (the heating rate was 10°C / min), and then calcined at a constant temperature of 700°C for 2 hours. After natural cooling, the rice husk biochar was obtained; the rice husk biochar was placed in a ball mill (including 14 Small steel balls with a diameter of 6.35 mm and 8 large steel balls with a diameter of 9.5 mm), uniformly pulverized for 30 minutes at 300 Hz to obtain rice husk-derived carbon powder with a par...
Embodiment 2
[0037] Under the condition of normal temperature and pressure, take carboxybetaine (x=13, n=8), prepare the carboxybetaine solution of 0.5% concentration, add rice husk according to the mass ratio of carboxybetaine and rice husk-derived carbon particles 10:1 The carbon particles are derived and mixed to obtain a foam release agent composition.
[0038] The preparation method of rice husk-derived carbon particles of this embodiment: the naturally air-dried rice husks are placed in a tube furnace, and the 2 The temperature was raised to 700°C under protective conditions (the heating rate was 10°C / min), and then calcined at a constant temperature of 700°C for 2 hours. After natural cooling, the rice husk biochar was obtained; the rice husk biochar was placed in a ball mill (including 14 Small steel balls with a diameter of 6.35mm and 8 large steel balls with a diameter of 9.5mm), uniformly pulverized for 25 minutes at 300Hz to obtain a rice husk-derived carbon powder with a parti...
Embodiment 3
[0041] Under normal temperature and pressure conditions, take carboxybetaine (x=15, n=10), prepare a 0.5% concentration of carboxybetaine solution, add rice husk according to the mass ratio of carboxybetaine and rice husk-derived carbon particles 5:1 The carbon particles are derived and mixed to obtain a foam release agent composition.
[0042] The preparation method of rice husk-derived carbon particles of this embodiment: the naturally air-dried rice husks are placed in a tube furnace, and the 2 The temperature was raised to 700°C under protective conditions (the heating rate was 10°C / min), and then calcined at a constant temperature of 700°C for 2 hours. After natural cooling, the rice husk biochar was obtained; the rice husk biochar was placed in a ball mill (including 14 Small steel balls with a diameter of 6.35mm and 8 large steel balls with a diameter of 9.5mm), uniformly pulverized for 25 minutes at 300Hz to obtain a rice husk-derived carbon powder with a particle size...
