Commonly used mosquito coils consist of more than 90% of carbon powder (or wood chips) and binders, a small amount of synergist, and different types of pesticides of different concentrations. Today, Xiaobian will take everyone to learn about the raw materials for making mosquito coils: First, the production of mosquito coil base      Mosquito base can be used: wood powder (can use wood powder and sawdust, the particle size is preferably passed through a 100 mesh sieve. It is a combustion agent and a base material.), corncob powder (particle size is preferably passed through a 100 mesh sieve. It is a combustion agent) And the base material.), sweet potato fermented slag powder (the residue of citric acid fermented by sweet potato, or the residue obtained by fermenting sweet potato to prepare alcohol, dried and pulverized powder. It is a combustion agent and a base material. The particle size is 100 The mesh screen is suitable.)      Adhesives are available: starch (corn starch or other starches. Used as a binder in manufacturing, combined with a combustion aid). Or an environmentally friendly industrial binder without harmful degradants.      Other additives: perfumes, colorants, etc., added as needed. It is better to use a water-soluble product.      Blank production: first dissolve the coloring agent, perfume, etc. in water to prepare an aqueous solution. Then, a small amount of the aqueous solution is added to the starch or the industrial binder, and after stirring and dispersing uniformly, the remaining aqueous solution is added, stirred and dispersed uniformly, heated and continuously stirred until the starch is completely gelatinized. What is the raw material for making mosquito coils? The wood powder, corn core powder and sweet potato fermented slag powder are uniformly mixed into the binder, and after thorough stirring, a thick paste is obtained. Finally, the above-prepared viscous paste is injected into the mold to form a sheet, and then poured into a frame to form a sheet, and then cut to obtain a formed body. Second, the preparation of effective insecticidal ingredients      Common insecticide ingredients are: dextromethrin, dextrorotatory trans-propyl pyrethroid, tetrafluthrin, cyfluthrin, tetrafluthrin, methoxyfluorfen, alkyne Promethrin and the like. The nature of these active ingredients is very similar: there is no change in the nature of storage for two years at room temperature, and it can be decomposed by strong alkali and ultraviolet light. The boiling point is 130°C-140°C/100Pa, and the toxicity grade is WHO(ai)II or WHO(ai). III. The above properties determine its use as the main active ingredient of mosquito coils. When the mosquito coil is ignited, the temperature of the ignition point of the mosquito coil reaches 500 ° C - 600 ° C, and the temperature of the part about 1 cm from the fire point reaches 100 ° C - 200 ° C. This temperature can make the active ingredient of the mosquito coil become gaseous. These gaseous active components are suspended in the air as the gas generated by the combustion of carbon and some of the smoke particles are lifted off. As the air flows with the mosquito's breathing movement, the mosquito's respiratory tract, esophagus and skin enter the mosquito body, killing the mosquito with its toxicity.      According to the needs, different kinds of pesticides can be formulated into a solution of the required concentration for use, and a small amount of synergist (such as synergistic ether, synergistic effect, octachlorodipropyl ether, synergistic phosphorus (SVl), synergy can be added. Ester, synergistic amine, etc.).      The insecticide is added into the production of the mosquito-repellent blank in a certain amount or directly sprayed on the finished blank, and the mosquito-repellent incense is dried or dried to be packed and used for later use.      What is the raw material for making mosquito coils? I believe that we have some understanding through the above introduction, I hope to bring you help.
