Abstract
The present invention provides a deodorizing article which can suppress the odor level to a predetermined level or lower and which can be used semi-permanently. The deodorizing article is produced by dispersing in gypsum series a clay mineral having a tunnel-like micro-structure, adding an optional mineral having a pore size greater than the gypsum series to the resultant mixture, and shaping the mixture.
Claims17
(Amended) A deodorizing article for use in an exhaust system where an odor component is present, characterized in that the deodorizing article comprises gypsum series, and a clay mineral having a tunnel-like micro-structure and dispersed in the gypsum series;
- that the deodorizing article adsorbs the odor component thereto;
- and that the deodorizing article releases the adsorbed odor component, when the odor component concentration is lowered.
(Amended) A method for producing a deodorizing article containing gypsum series and a clay mineral having a tunnel-like micro-structure and dispersed in the gypsum series, so as to adsorb the odor component thereto and release the adsorbed odor component, when the odor component concentration is lowered,
- characterized in that the method comprises the steps of subjecting the clay mineral having a tunnel-like micro-structure to preliminary firing at a predetermined temperature;
- dispersing the thus-fired clay mineral having a tunnel-like micro-structure in the gypsum series and charging the resultant mixture in a mold;
- and drying the mixture and releasing the dried product from the mold.
