CONCENTRATED CHLORINE DIOXIDE GAS SUPPORTING MATERIAL SUPPORTING CHLORINE DIOXIDE GAS OF HIGH CONCENTRATION, ENABLING VISUAL RECOGNITION OF RESIDUAL AMOUNT OF CHLORINE DIOXIDE GAS IN USE, WITH BEAUTIFUL APPEARANCE AND LONG-TERM STORAGE STABILITY AND ENABLING CONCENTRATION CONTROL IN USE, USE THEREOF AND METHOD FOR STORING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a method for developing, producing, using and storing a chlorine dioxide gas supporting material which can remove microorganisms, malodor and other chemical substances in a space and has excellent appearance, thereby provides a hitherto absent space-cleaning agent supporting chlorine dioxide gas having high concentration, stores the gas for a long time, releasing an arbitrary amount of the gas in use, and enables visual recognition of the residual amount of the chlorine dioxide gas in use. PSOLUTION: The supporting material is produced by impregnating a sodium chlorite solution in a transparent silica gel having a pH of 6.0, drying under reduced pressure at 35C, to prepare a silica gel capable of supporting concentrated chlorine dioxide gas, adding 1% of silica gel based on the weight of the supporting silica gel, sealing with a chlorine dioxide gas permeable film having one or more fine pores having a diameter of 0.3 nm and 100,000 nm, putting the product in a bag or a vessel having a carbon dioxide gas permeability of 10 mL/(mSP2/SPday/MPa) and a water vapor permeability of 5 g/(mSP2/SPday), evacuating to 100 torr, to heat seal the bag, etc. PCOPYRIGHT: (C)2011,JPO&INPIT
