Aqueous prescription liquid-liquid heating evaporation core, and method for producing the same, and aqueous prescription liquid-liquid heating evaporation method using the aqueous prescription liquid-liquid heating evaporation core

摘要

The liquid wick for heating and transpiration that can be used for transpiration of a chemical solution containing pyrethroid insecticidal components with a relatively high vapor pressure exhibits stable transpiration performance and high insecticidal efficacy at the time of use. Further, it is possible to provide a liquid wick for heating and transpiration capable of maintaining the transpiration performance of the liquid wick even if a predetermined time has passed from the manufacture, as well as preventing the liquid chemical leakage due to the falling of the liquid chemical container. It is a liquid wick for heating and transpiration to evaporate a chemical solution containing a pyrethroid insecticidal component having a vapor pressure of 2 × 10 −4 to 1 × 10 −2 mmHg at 30 ° C., and inorganic powder as a raw material, The raw material contains an inorganic caking agent and an organic substance, and the ratio (W1 / W2) of the total weight (W1) of the inorganic powder and the inorganic caking agent to the weight (W2) of the organic substance is 4.0 It is set to -10.
