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.

왕겨 분말을 가연성 담체로 첨가하여 분상, 과립상 및 봉상의 fenarimol 훈연제를 제제하고 제형이 훈연제의 연소성에 미치는 영향을 조사하였다. 가연성 담체로 목분을 사용한 목분 훈연제의 연소성을 조사하고 왕겨 훈연제와 비교하였다. 왕겨 분말을 가연성 담체로 한 fenarimol 훈연제(3%)는 분말, 과립 및 막대 모양으로 성형할 수 있었으며, 염소산나트륨 첨가비가 11% 이상일 때 모두 연속적으로 연소하였다. 형상과 무관하게 모두 염소산나트륨 첨가비가 13%인 훈연제의 훈연율이 가장 높았으며, 분상 훈연제(64.5%) < 과립훈연제(78.4%) < 봉상 훈연제(90.9%) 순으로 훈연율이 증가하였다. 봉상 훈연제는 과립훈연제보다 점화가 특히 용이하고 강도와 훈연율이 우수하였다. 목분을 가연성 담체로 사용한 훈연제는 방염 성분을 함유하여 연소 시간이 매우 길어지는 특성이 있어서 훈연제보다 서서히 연소하는 훈증제용 담체로 더 적합하였다.
