蚊香对可燃物的引燃特性研究

Study on characteristics of combustible ignition caused by mosquito-repellent

本文通过蚊香引燃多种可燃物的实验,研究了蚊香使用中的消防安全问题。结果表明,蚊香能否引燃可燃物与可燃物种类、自身状况和数量有关。蚊香容易引燃纸张、海绵等结构疏松、燃点低、蓄热性能好的物质,不能引燃毛料、化纤织物、聚氨酯泡沫塑料、胶皮等高分子材料。达到一定量的可燃物在干燥和疏松、细碎的状态下,蓄热能力强,因而容易被蚊香点燃,火灾危险性较大。使用蚊香时应避免和这类物质接触,以防引起火灾。

Fire security of mosquito-repellent is investigated in this paper with the experiments of several combustibles ignited by mosquito-repellent. The results show that whether mosquito-repellent can ignite com- bustible matters is related to the types, situations and quantities of combustible matter itself. Mosquito-repel- lent can ignite materials easily with loose structures, a low flash point, and good heat storing quality, such as paper, sponge and so on. But high polymer materials like wool, chemical fiber fabrics, polyurethane forms and rubber etc. can not be ignited. Tne combustibles with a certaint amount and in dry, loose and fine state have larger capacity of heat storage, and thus are ignited easily by mosquito-repellent, at larger risk of fire. So mosquito-repellent should be kept away from such materials in case of fire.
