Abstract
In order to study the effect of formulation type on the burning characteristics of smoke generator, fenarimol smoke generators containing the powdered rice chaff as a combustible carrier were prepared by molding the kneaded mixtures into various shapes. Smoke generators containing wood flour as a combustible carrier were also prepared and compared with smoke generators containing rice chaff. All the fenarimol smoke generators moulded into powders, granules, and rods continuously burned out when the sodium chlorate content exceeded 11%. Regardless of their types, the highest smoking rate of fenarimol was observed with more than 13% of sodium chlorate. The smoking rate of active ingredient followed with the increasing order of powder (64.5%) < granule (78.4%) < rod (90.9%). The smoke rod was robust, easy to ignite, and showed the highest smoking rate among the tested formulations. When the mixture of wood flour and anti-flame agent was used as a combustible carrier, the burning rate was so slow that wood flour formulation seemed to be more suitable to a slow-burning fumigant rather than smoke generator.
