Absorbent core for heating and discharging aqueous prescription chemical vapor, and its manufacturing method, and aqueous prescription chemical vapor deposition method using liquid core for heating and drying the aqueous solution
Problem to be solved: in a suction core for steam evaporation which can be used for transpiration of a chemical substance containing a pyrethroid insecticide having a relatively high vapor pressureStable transpiration and high insecticidal efficacyOf course, it is possible to prevent the leakage of chemicals caused by the internal pressure rise of the chemical container and the liquid leakage of the chemical containerA liquid core for heating and evaporation can be maintained to maintain the transpiration performance of the liquid core even after a certain period of time has elapsed from the manufacture.Solution: a suction core for evaporating a chemical liquid containing a pyrethroid insecticide having a vapor pressure of 2. Times. 10. Sup. - 4 to 1. Times. 10. Sup. - 2 mmHg at 30 ° C.As raw materialInorganic powder andInorganic binderContains organic matterIn raw materialsThe total weight (W1) of inorganic powder and inorganic binderThe ratio (W1 / W2) of the organic substance to the weight (W2) is set at 4.0 to 10.No selection【課題】比較的蒸気圧が高いピレスロイド系殺虫成分を含有する薬液の蒸散に使用可能な加熱蒸散用吸液芯において、使用時に安定した蒸散性能と高い殺虫効力とを奏し、薬液容器の内圧上昇による薬液漏れや薬液容器の転倒による薬液漏れを防止できるのは勿論のこと、製造から一定の時間が経過しても吸液芯の蒸散性能を維持することが可能な加熱蒸散用吸液芯を提供する。【解決手段】３０℃における蒸気圧が２×１０－４～１×１０－２ｍｍＨｇであるピレスロイド系殺虫成分を含有する薬液を蒸散させるための加熱蒸散用吸液芯であって、原材料として、無機質粉体と、無機質粘結剤と、有機物質とを含み、原材料において、無機質粉体及び無機質粘結剤の合計重量（Ｗ１）と、有機物質の重量（Ｗ２）との比率（Ｗ１／Ｗ２）が４．０～１０に設定されている。【選択図】なし
