Wherein, tables 2-4 show the comparison of some products sampled from a batch of mosquito coil produced according to the method and the proportion of the mosquito coil in example 1 with commercial mosquito coils, and the percentage in the table shows the deviation from the average value. The production date of the mosquito-repellent incense is 2017 for 3 months, the commercially available mosquito-repellent incense is from a supermarket, the production date is 2017 for 3 months and 16 days, the marked indexes are 35g of disc weight, 0.08 percent of meperfluthrin by mass, the burning time is one night, and the color is black. As can be seen from table 2, the coil weights of the mosquito coil of the present invention are mainly distributed within a deviation range of ± 2%, and the coil weights are very stable, while those of commercially available products are mainly distributed within a deviation range of ± 6%, resulting in difficulty in controlling the coil weights, and further, difficulty in controlling the repellent content and burning time, resulting in unstable product quality. As can be seen from table 3, the content of the insect repellent in the present invention is mainly within a deviation range of ± 5%, the content of the insect repellent is relatively stable, while the content of the insect repellent in the commercially available product is mainly within a deviation range of ± 15%, the deviation of the content of the insect repellent is relatively large, the mosquito repellent effect cannot be achieved at a low insect repellent content, and the cost is significantly increased at a high insect repellent content, in order to solve the problem of instability of the insect repellent in the prior art, an additional 5-20% of the insect repellent amount is usually added to the standard content to ensure the mosquito repellent effect, and the cost is increased in a phase-changing manner (the increased cost is almost the same as the increased cost of the dry blanks in the present patent). As can be seen from Table 4, the burning time of the present invention is mainly distributed within a deviation range of + -2%, the burning time is very stable, while the burning time of the commercial product is mainly distributed within a deviation range of + -6%, the deviation of the burning time can reach 10% at most, and the burning deviation exceeding half an hour can cause poor experience of users.
In conclusion, as can be seen from tables 1-4, the mosquito incense produced by the invention has various indexes reaching or exceeding the industrial indexes, and has stable parameters such as coil weight, insect repellent content, burning time and the like, and the cost is reduced by accurately controlling the phase change of the parameters.
