After all kinds of different raw materials are prepared in a certain proportion, 140-180 mesh nylon screen is used for repeated screening. The more uniform it is, the better. (If it is not uniform, it will affect the combustion effect.) Then mix the sieved raw materials with a ratio of glue to water and mix them into a paste. Insert the purchased matchstick into a three-plywood board with many small holes, flip it and take the liquid, and dry it. Do not set it on fire. The key thing is to suck enough paraffin on one end of the matchstick.(The oil can be heated and dissolved first. Insert one end of a matchstick in the oil and remove it immediately. It is not easy to burn.)
