ENCAPSULATED AEROSOLS
Abstract
A two-stage microcapsule generator has been utilized to produce a variety of liquid core microcapsules. A number of operational and design changes have been made to improve the performance of the generator and to increase its versatility. The generator has been used to provide microcapsules of dibutyl phosphite in rubber, dibutyl phosphite in paraffin, and dibutyl phosphite in polyethylene. Studies were made of the effect of film coating on the evaporation rate of dibutyl phosphite microdroplets. An investigation was made of the effect of solution concentration on coat thickness in spraydried microcapsules. Nozzle design was found to be a critical parameter. (Author)
