Abstract
Explanation was made of problems in interparticulate coagulation mainly in the mixing process of microparticulates which are less than 0.1[mu]m in diameter and about 1[mu]m diameter particulates for the composition in gaseous phase. The utilization of electrostatic interaction was particularly explained together with the recent result of basic experiment. The composition of two-component particulate system in the gaseous phase progresses generally with the Brownian movement and electrostatic interaction of particulates. The interparticulate collision/coagulation rate is evaluated by the coagulation rate function. As for the electric charging operation to make the coagulation more effective, application is made of contact or collision charging and ionic charging, and the latter is further divided into electric field charging and diffusion charging. Experiment was conducted by mixing TiO2 microparticulates which were less than 100nm in diameter and about 1[mu]m diameter PSL (polystyrene latex) particulates for the composition in a mixer. As a result of investigating the coagulation process with a device which could observe the diffused laser beam from the particulates, confirmation could be made of the situation in which the particulate charging effectively contributed to the composition. 20 refs., 10 figs., 2 tabs.
