The side of the matchbox is coated with red phosphorus (igniting agent), antimony trisulfide (Sb2S3, flammable) and glass powder. The materials on the advertising matches head are generally potassium chloride, manganese dioxide (oxidant), sulfur (combustibles) and so on. When the two sides rub against each other, the heat generated by the friction ignites the red phosphorus in contact with potassium chloride, causing the combustible material on the advertising matches to head to burn, which causes the matchstick to catch fire.
2KClO3+3S→2KCl+3SO2+1137kJThe above chemical reaction is too intense, and the ignition is too intense, so it is not suitable for use. Filler powder, such as quartz powder, should be added to the match head to moderate and stable the fire; additionally, the addition of potassium dichromate and pigments can improve the moisture resistance and appearance of the match head. You can make a sulfur-free aromatic match by replacing sulfur with starch, shellac, and other ingredients and adding spices. It does not emit the toxic gas SO2, emits fragrance, and makes people feel at ease when burned.
The advantage of safety advertising matches is that red phosphorus is non-toxic. It and the oxidizer adhere to the matchbox and the matchstick sides, respectively, and do not touch them when not in use.
