GERMICIDAL MATERIAL FOR AERIAL APPLICATION

摘要

PROBLEM TO BE SOLVED: To provide a germicidal material for aerial application capable of efficiently contacting harmful microorganisms with a germicidal agent. SOLUTION: The germicidal material for aerial application charges the surface of a germicidal material with electric charge reverse to the charge of the surface of a harmful microorganism to attract the harmful microorganism floating in air and charged with electric charge reverse to the charge of the charged material scattered in air together with a germicidal agent and contact the microorganism with the germicide. The germicidal effect of the germicide is fully exhibited by the method to increase the controlling effect on the harmful microorganisms. The surface charge of harmful microorganism is positive at pH 4 or below and is negative at pH of higher than 4. Since the quantity of electric charge is≥10μV or≤-10μV or thereabout, the surface charge of the germicidal material for aerial application is preferably≥10μV or≤-10μV. The germicidal agent is an antagonistic microorganism, a chemical germicide or an antibacterial substance. COPYRIGHT: (C)2007,JPO&INPIT
