How to make matches

Dipping medicine is an important process in the process of making matches, and the quality of dipping medicine determines the ignition quality of matches.

Matches stained with medicine move slowly on a continuous machine and will enter the next packing process. After impregnation, the inspector will conduct ignition quality inspection.

Dipping workshop of match factory. Matches soaked in medicine are pushed to the next workshop by workers, and unqualified match stems are removed by screening machines.

There are two ways to put matches into the matchbox: manual and machine. Half of it is done by hand and the other half is given to the machine.

Although the machine is fast, the breakage rate is high. The last process of making matches, 10 is packed in a small bag, which can be packed before leaving the factory. In this process, it is all done by hand.

Extended data:

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, MnO2 (oxidant) and S (combustible).

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.
