<P>PROBLEM TO BE SOLVED: To provide a spray product of high quality in which none among fluorocarbon gas, alternative fluorocarbon, or the like, is used, a less expensive jetting agent of superior ozone-depleting potential and superior global warming potential is used, and the safety and the liquid-holding properties are enhanced. <P>SOLUTION: In a dust-removing blower, a mixture of dimethyl ether and carbon dioxide is used for a jetting agent; an absorbing body for holding the propellant is constituted of pulverized cellulose fiber aggregate, while the cellulose fiber contains at least 45 mass% fine cellulose fibers of the fiber length of 0.35 mm or shorter; and the propellant is filled in a spray can having an ejector. <P>COPYRIGHT: (C)2009,JPO&INPIT |
