火柴全身都是容易着火的东西:它头上蘸着的是三硫化二锑和氯酸钾,火柴木梗浸过石蜡和松香的混合物,火柴盒的两边是涂有红磷的摩擦层。当我们拿上火柴在火柴匣边上一擦的时候,火柴头由于摩擦面产生的热量足够引起火柴头接触的一部分红磷着火,这火使火柴头上的氯酸钾受热而放出氧气,同时放出热量,它们很快地引燃了三硫化二锑,于是,火柴就“嗤”的一声,爆出火苗来,并进一步引起火柴梗的燃烧。 The matches were easy to catch on fire: it was dipped with antimony trisulfide and potassium chlorate, and the matchstick was soaked in a mixture of paraffin and rosin that the sides of the matchbox were rubbed with red phosphorus. When we get a match on the edge of the matchbox wipe, the match head due to the heat generated by the friction surface enough to cause the match head contact with a portion of the red phosphorus fire, the fire head of potassium chlorate on the match to release oxygen and release heat , They quickly ignited the antimony trisulfide, so the match on the “laugh” sound, burst out flames, and further cause the burning of matchstick.
