| description | A supercritical fluid material mixing method for a superfine-granularity ceramic abrasive tool comprises the following steps that (1) according to weight percentage, 25%-50% of abrasive materials, 4%-26% of ceramic binding agent and 1-25% of wetting agent are fed into a high-pressure kettle, and the high-pressure kettle is sealed; (2) carbon dioxide is fed into the high-pressure kettle, the pressure is adjusted to 72.8 atm, the temperature is adjusted to 31.1 DEG C and above, the carbon dioxide is made to reach the supercritical state, and stirring is conducted for 1-3 h. Researches are conducted for solving the problem that in the superfine abrasive tool preparing process, since the surface energy of powder is high, agglomeration is quite prone to happen, the supercritical liquid carbon dioxide which is quite high in penetration capacity is utilized to fully infiltrate gaps of agglomerated bodies, the purpose of weakening the binding force between particles is achieved, the problem that in the superfine abra |
