What types of matches are there?

Classification of matches:

According to their uses and ingredients, matches can be divided into two categories: daily matches (ordinary matches) and special matches.

1. Daily matches:

According to the packaging appearance and the raw materials used, there are three types of matches: wooden stem matches, wax paper stem matches and book-style matches.

1. Wooden stem matches: Match stems with a square cross-section are made from relatively soft wood. The ends of the stems are dipped in paraffin and medicine slurry. After drying, they are packed in small boxes made of wood chips or cardboard. The sides of the box are coated with phosphorus. The most common match.

2. Wax paper stem matches: wax stem matches for short. Tissue paper is soaked in molten paraffin and extruded into long stems with a round or square cross-section, which are then cut into match stems.

3. Book-style matches: so named because of their flat, thin packaging that looks like a book. The stems are die-cut from wood chips or cardboard.

2. Special matches:

Use special head formulas to produce different special functions. There are mainly the following five types:

1. Wind-resistant and waterproof matches: The head contains about 15% more oxidants than ordinary matches, and has stronger ignition performance; the surface is coated with a moisture-proof film to prevent moisture.

2. High-temperature matches: The medicine head is divided into two layers: inner and outer. The inner layer is made of wind-resistant and waterproof match ingredients; the outer layer is made of ferric oxide, aluminum, magnesium powder and other raw materials, bonded with nitrocellulose solution. The size and specifications are similar to wind-resistant and waterproof matches. When burned, it can produce high temperatures above 1200°C, which can be used to ignite the welding agent, so it is also called a welding match.

3. Signal match: also called signal tube. The diameter of the barrel is 2.5~3cm and the length is 16~38cm. A phosphorus layer is applied to the end of the cylinder cover. The medicine is mixed with materials such as strontium nitrate, barium nitrate, and basic copper carbonate. After burning, it can emit continuous flames of different colors such as red, blue, and white.

4. Multiple burning matches: Can fire repeatedly and burn multiple times. This kind of match does not use a wooden stem, but is made of chemicals such as potassium chlorate, sulfur, cellulose diacetate, paraformaldehyde and fillers, mixed with acetone and pressed into a rod-shaped match with a diameter of 2 to 5 mm, called a match core (no match). (divided into stems and medicinal heads), it can be used to scratch the phosphorus layer to produce fire.

5. Sensitive matches: they emit light when burned and can sensitize photographic films after illuminating objects. Can be used instead of flash for photography.
