<p><P>PROBLEM TO BE SOLVED: To discriminate the kind of the resin of a laminated resin product molded by superposing two or more kinds of plastics one upon another, or a laminated resin product molded so as to hold another kind of resin or a member, especially a thin-walled resin product or a sheetlike resin product by infrared analysis. <P>SOLUTION: The method for discriminating the kinds of resin constituted so as to discriminate the kinds of the resin of the resin product is equipped with: a resin discrimination step for subjecting the front and back of the resin product to infrared analysis and collating two obtained measured spectra with each other to identify whether the front and back of the resin product comprise the same resin; a discrimination step for discriminating the kinds of the resin by collating the measured spectra with the database spectrum of a known material; a specific gravity measuring step for measuring the specific gravity of the resin product; and a collation step for collating the specific gravity of the resin product obtained from the specific gravity measuring step with the specific gravity based on the kind of the resin obtained from the discrimination step. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
