Embodiment 1
[0019] A method for preparing bone charcoal powder with strong color fixation for preparing bone china, comprising the following steps:
[0020] 1) Select fresh animal bones, then crush them, put them into a vacuum tank, add distilled water, the air pressure in the air tank is 0.01MPa, the temperature is 65°C, and heat for 2 hours;
[0021] 2) Put the aggregate processed in step 1 into the mixer, start the mixing, control the speed to 2500r / min, and stir at a high speed for 20 minutes, then sort it to remove the tendon and soil attached to the surface of the bone drop to get a clean bone;
[0022] 3) Put the aggregate treated in step 2 into the oil extraction pot, add benzene, pass the heating coil in the oil extraction pot into steam to heat continuously, and the benzene and the water in the aggregate form a benzene and water azeotrope , condensed by the condenser, benzene and water are separated, the benzene phase is refluxed into the oil extraction pot for circulation, and...
Embodiment 2
[0029] A method for preparing bone charcoal powder with strong color fixation for preparing bone china, comprising the following steps:
[0030] 1) Select fresh animal bones, then crush them, put them into a vacuum tank, add distilled water, the air pressure in the air tank is 0.03MPa, the temperature is 80°C, and heat for 2.5h;
[0031] 2) Put the aggregate processed in step 1 into the mixer, turn on the mixer, control the rotation speed to 3500r / min, stir at a high speed for 30 minutes, and sort it to remove the tendon and soil attached to the surface of the bone drop to get a clean bone;
[0032] 3) Put the aggregate treated in step 2 into the oil extraction pot, add benzene, pass the heating coil in the oil extraction pot into steam to heat continuously, and the benzene and the water in the aggregate form a benzene and water azeotrope , condensed by the condenser, benzene and water are separated, the benzene phase is refluxed into the oil extraction pot for circulation, a...
