Atomizing Performance of Non-Heating Fog Machine

The paper deals with the closed-spaced atomizing performance of a non-haeting fog machine which was extensively used for protection in a vinyl greenhouse. The electrode near the nozzle of this machine could spray with electrostatic charge, which makes it possible to check through the atomizing performance with or without electrostatic charge. The test results showed that:(1) particles within a size of 10 ～ 30μm could be dispersed extensively;(2) electrostatic charge could make spray particle size smaller and make atomization and adherability to back side of our copper test plate better than that of spray particles without electrostatic charge.
