Consideration on standard substance for the conbustion test of oxidizing solid. Sankasei kotai no nensho shiken no kijun busshitsu ni kansuru kosatsu

Abstract

The mixture of KClO {sub 3} and wood flour is the standard substance in the combustion test by the Fire Service Law to investigate the accelerating combustion of an oxidizing agent, but it is difficult to measure the combustion time owing to the intermittent combustion. This paper described the study to get any compounds superior to the above mentioned. Since the mixture of KNO {sub 3}-wood flour combusts more rapidly than that of KClO {sub 3}-wood flour, a new mixture of similar combustion rate to that of the mixture of KClO {sub 3} and wood flour and without intermittent combustion was tried to get by adding an inactive solid powder to decrease the combustion rate. But a new mixture which has the combustion time of about 4 minutes, shows uniform combustion instead of intermittent combustion and shows the only slight variation of combustion time, could not be found. It is because of intermittent combustion that the mixture of KClO {sub 3} and wood flour can endure the combustion for 4 minutes although this mixture has larger reaction heat. The combustion time of this mixture is shortened if the igniting nichrome wire temperature exceeds 1,000 centigrade. Further, the bulk density of  More>>
