Embodiment 2
[0084] By nucleating at 200°C and growing at 290°C, the uniform and controllable preparation of Fe 2 o 3 Magnetic nanoparticles as an example. (The preparation of each unit component of the system is the same as that in Embodiment 1)
[0085] Program control flow see Figure 14 and Figure 15. Turn on the switch of the high-precision automatic nanomaterial synthesis system and the switch of the computer 2, the microprocessor 1 monitors and controls the initialization process of each functional unit, and reports the initialization data to the computer 2 via the data bus 4. The initialization data includes: the initial position of the syringe pump, the initial temperature of the reaction solution, the temperature of the chemical reaction chamber, the air pressure of the multifunctional reaction kettle, and the like. The computer 2 issues instructions and takes over the control of the microprocessor 1; the computer 2 issues instructions to programmatically monitor and contro...
