Advantages Of Safety Matches
Oct 24, 2022
The components of the safety match are: the match head is mainly composed of oxidant (KClO3), combustibles (such as sulfur) and adhesives. The side of the match box is mainly composed of red phosphorus, antimony trisulfide and adhesive. When a match is struck, the match head and the side of the match box rub to generate heat. The heat released causes KClO3 to decompose, generating a small amount of oxygen, which causes red phosphorus to ignite, thus causing combustibles (such as sulfur) on the match head to burn, thus the match is struck.
The advantage of safety matches is to separate red phosphorus from oxidant, which is not only safer, but also non-toxic. So it is also called safety match. The match head mainly contains potassium chlorate, manganese dioxide, sulfur and glass powder. There is a small amount of paraffin on the match rod. The friction layers on both sides of the match box are made of red phosphorus and glass powder. The main process of match ignition is: (1) When the match head moves on the match box, the heat generated makes phosphorus burn; (2) The heat released by phosphorus combustion decomposes potassium chlorate; (3) The oxygen released from the decomposition of potassium chlorate reacts with sulfur; (4) The heat released by the reaction of sulfur and oxygen ignites the paraffin and finally ignites the matchstick.
