LIQUID-SUCKING WICK AND DRUG-EVAPORATION METHOD

摘要

PURPOSE:To provide an easily producible liquid-sucking wick for sucking-type thermal evaporation device, made of wood or bamboo and having further improved structure and performance. CONSTITUTION:The objective liquid-sucking wick is produced by cutting wood or bamboo in columnar shape in the direction of the fiber. The liquid-sucking wick 1 is soaked with a chemical liquid 2 composed of a pyrethroid-containing aqueous solution and is heated with a heater 4 to evaporate the chemical liquid 2. The chemical agent can be evaporated without deteriorating the physical properties of the liquid-sucking wick.
