Abstract: A sealing agent stock solution 20 is prepared by preparing a mixed solution 14 by mixing a rubber latex, a resin emulsion and a surfactant, and a predetermined amount of water in a solution preparation vessel 12, followed by adding an anti-freeze agent 18 to the mixed solution 14. The sealing agent stock solution 20 is held (left standing still) at least over for 24 hr or more and preferably over for 48 hr or more without stirring in the solution preparation vessel 12, followed by filtering the sealing agent stock solution 20 with a filter member 26 made of a mesh filter having the mesh number from 50 to 400 mesh to remove latex aggregates 36 generated in the sealing agent stock solution 20, and thereby a sealing agent 10 that does not contain the latex aggregates 36 is produced.

Abstract: An object is to provide an air bacteria removal device in which leakage of electrolytic water to the outside is eliminated as much as possible and in which maintenance can easily be performed, the air bacteria removal device comprises a main body including a water storage section having a sealed or semi-sealed structure in which the electrolytic water is stored, and a water absorption member for supplying the electrolytic water from the water storage section to an air-liquid contact member by use of a capillary phenomenon, the air-liquid contact member and the water absorption member are integrated and detachably attached to the main body, the water absorption member attached to this main body enters the water storage section, and is submerged into the electrolytic water, and the water storage section is brought into a sealed or semi-sealed state.
