According to the difference of chemical deposition behavior of arsenic and iron ion in the different pH value solution, valuable element Fe was first recovered by the selective deposition from bio-oxidation wastewater and then it was used to prepare nano-iron oxide red pigment powders. The effect of purifying conditions, calcinations temperature and calcinations time on the product color, the average partical size had been investigated. The crystal structure, particle-size and properties of the nanoparticles were characterized by means of XRD, TEM. The optimal process conditions of the preparation of iron oxide red were: calcinations temperature was 900°C, calcinations time was 120min. Under these conditions, the color of production was bright red. The particles were fully developed, and the average diameter of nanometer particle was about 70.8nm. In the visible light region of 380 to 780nm, the particle possessed good transparency, achieving the standard of GB1863 – 89.

“…In order to improve the uniformity of the droplets, the satellite droplets have been suppressed with a harmonic method [15]. The amplitude-modulated disturbance method has been developed to generate the arbitrary droplet formation [16,17]. Meanwhile, the influences of wavelength on droplet generation have been also studied.…”

The influences of the disturbance frequency on the metal droplet generation are investigated for microdroplet deposition manufacture. The polynomial distribution model is assumed for the jet velocity profile. The optimal disturbance frequency is predicted according to the linear stability analysis. The jet velocity converges and the uniform droplets are generated at the optimal disturbance frequency in the simulation. Experiments have been conducted with the orifice diameter of 150 mm. The formation and diameter of Sn60/Pb40 droplets are estimated under the actions of the different frequency. Results show that the accuracy of the droplet shape and diameter are improved. A narrow-sized log-normal distribution is obtained and the diameter deviation is about 2.59 per cent at the optimal disturbance frequency of 3.89 kHz. Good agreements between the theoretical predictions and experimental values indicate that the optimal disturbance frequency is well predicted with a frequency deviation of less than 1.03 per cent. These works are useful when selecting the operating parameters for manufacturing.
