PROBLEM TO BE SOLVED: To provide an apparatus for chemical volatilization capable of preventing invasion of flying insects into a space which is the barrier space of a volatile chemical made by volatilizing a large amount of the volatile chemical around the same in a short time of &le12 hours.SOLUTION: There is provided the apparatus for chemical volatilization which volatilizes the volatile chemical by rotating a carrier of the chemical on which the volatile chemical is carried, wherein 10-50 mg volatile chemical is brought to be carried on the chemical carrier, while &ge50% of the carried amount is volatilized within 12 hours from the initiation of use to form the barrier space of the volatile chemical around the same and the invasion of flying insects into the space is prevented by the apparatus for chemical volatilization. The chemical carrier is preferably brought to carry the volatile chemical by a lattice shaped or a net-like fiber structural body of a non-textured polyester-based fiber.COPYRIGHT: (C)2012,JPO&INPIT【課題】12時間以内の短時間に高薬量の揮散性薬剤を揮散させてその周囲に揮散性薬剤のバリア空間を形成し、飛翔害虫のこの空間への侵入を阻止しうる薬剤揮散装置の提供。【課題の解決手段】揮散性薬剤が担持された薬剤担持体を回転せしめ前記揮散性薬剤を揮散させる薬剤揮散装置において、前記薬剤担持体に前記揮散性薬剤を10~50mg担持させると共に、使用開始から12時間以内に担持量の50%以上を揮散させてその周囲に前記揮散性薬剤のバリア空間を形成し、飛翔害虫のこの空間への侵入を阻止するようになした薬剤揮散装置。前記薬剤担持体は、テクスチャード加工されていないポリエステル系繊維の格子状もしくは網状繊維構造体に前記揮散性薬剤を担持させたものが好ましい。【選択図】なし
