STUDY ON THE CHARACTERISTICS OF AEROSOL FOR GLAZE ICING MANUAL INTERVENTION
Weather modification technology has been widely applied in social production and life, such as artificial rainfall and artificial hail dissipation. This paper introduces a new kind Agl aerosol formula. It can be used for specific manual interference operation to glaze icing aimed to the transmission line icing hazard, and it broadends the application field of weather modification. This new type aerosol is prepared by casting moulding and it has the feature of simple process. Through the test of the aerosols ignition performance and combustion performance, we find that it is of great advantages in reliable ignition performance, stable combustion performance, appropriate burning rate and suitable burning rate pressure index at -20℃ and 0.2 standard atmospheric pressure. It not only has excellent coubustion performance, but also solve the problem that under low temperature and low pressure condition conventional aerosol isnt suitable for seeding operation by propellant rocket or airplane. In addition, we established an experimental device that evaluated the nucleation rate and icing efficiency of the aerosol particles. The undercooling catalysis effect of the aerosol is verified by the new experimental method. It has a higher nucleation efficiency and a better icing catalytic function, in laboratory simulation of atmospheric environment. At last, the icing catalysis principle of the aerosol and its engineering-oriented implementation are simply described and discussed.
