我国是世界最大的香烟生产国,也是世界上最大的烟草消费国。吸烟不仅是威胁公民身体健康的一大公害,而且也是引起火灾事故的最大原因之一。那么,为什么吸烟容易引起火灾呢? 主要原因是点燃后的香烟具有较高的温度,据测试,点燃后的香烟温度在700℃左右,一支香烟持续燃烧的时间约为15分钟左右,时间较长。 常见的可燃物的自燃点和燃点都很低,如纸张、棉、麻及其织物等,其燃点大都在200℃—300℃,而香烟点燃后的温度比起这些固体可燃物的燃点温度高出二至三倍。因此,未熄灭
My country is the world’s largest producer of cigarettes and also the largest consumer of tobacco in the world. Smoking is not only a public nuisance that threatens the health of citizens, but also one of the biggest causes of a fire accident. So, why smoking easily lead to a fire? The main reason is that after ignition the cigarette has a higher temperature, according to the test, the ignition temperature of the cigarette is about 700 ℃, a cigarette burning time is about 15 minutes, time is more long. Common combustibles have very low autoignition and ignition points, such as paper, cotton, hemp and their fabrics, which burn at temperatures between 200 ° C and 300 ° C, whereas the temperature at which the cigarette ignites is higher than the ignition temperature of these solid combustibles Out two to three times. Therefore, did not go out
