Matches are a kindling tool which is ignited by friction based on the principle that objects generate heat by friction, using the chemical activity of strong oxidants and reducers.

/kloc-in the second half of the 0/8th century, yellow phosphorus was mainly used as an igniter. Because yellow phosphorus is toxic, it is gradually replaced by phosphorus sulfide matches. Although the latter is non-toxic, it may spontaneously ignite at any time, which is very unsafe. 1855, the match factory established in Sweden in the world successfully developed safety matches, which were gradually adopted by all countries in the world.

At present, the side of the matchbox is coated with red phosphorus (igniter), antimony trisulfide (Sb2S3, flammable) and glass powder; The substances on the matchhead are generally KClO3 (oxidant) and MnO2 (catalyst)? [6]? And s (flammable). When the two are rubbed, the heat generated by the friction ignites the red phosphorus in contact with KClO3, etc., and makes the combustible materials on the match head burn, thus causing the match stick to catch fire. The advantage of safety matches is that red phosphorus is non-toxic. It is attached to the side of matchbox and matchstick with oxidant, so they do not touch each other when not in use. That's why it's called a safety race.

The usual methods: on the one hand, use flammable wood as a stick (called a matchstick), and one end is dipped in wax oil and medicinal materials containing potassium chlorate (called a matchhead) as a match; On the other hand, the surface of the packaging box is coated with phosphorus containing red phosphorus and white phosphorus. When in use, it is very convenient to strike a match on the phosphorus surface and light it.

Classification: Matches can be divided into daily safety matches, ordinary matches, high-grade matches and various special matches.

The general process of manufacturing technology mainly includes: sawing wood, peeling bark, rotating slicing, cutting stems and drying; Screening, stem trimming, stem discharging, oil soaking, slurry dispensing, drug soaking, drying, stem unloading, box throwing, box cutting, box pasting and drying; Packing (paper box includes printing, indentation, cutting, pasting and packing), packing, preparing phosphorus slurry, brushing phosphorus, packaging and packing.

There are many types and models of match equipment, which can be roughly divided into six categories: (1) log decomposition equipment; (2) Manufacturing equipment of branches; (3) Branch processing equipment; (4) Match (head stalk) manufacturing equipment; (5) Box manufacturing equipment; (6) Matching packaging equipment.
