Title:
METHOD FOR EVALUATING FLUORORESIN PAINT OR FLUORORESIN COATING FILM, EVALUATION-INFORMATION CALCULATION DEVICE, EVALUATION-INFORMATION PRESENTATION SYSTEM, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/093180
Kind Code:
A1
Abstract:
The purpose of the present invention is to evaluate the weather resistance of a fluororesin paint or a fluororesin coating film. An evaluation-information calculation device (20) acquires a chromatogram related to a sample (S). The evaluation-information calculation device (20) estimates, on the basis of the chromatogram and data related to peaks of thermal decomposition products derived from constituent units based on vinyl ester and/or vinyl ether, the presence and/or amount of the constituent units based on vinyl ester and/or vinyl ether in the sample (S). The evaluation-information calculation device (20) estimates the fluorine content of the sample (S) on the basis of the chromatogram and data related to peaks of thermal decomposition products derived from constituent units based on monomers including fluorine. An evaluator (E) evaluates the sample (S) on the basis of the fluorine content, and the presence and/or amount of the constituent units based on vinyl ester and/or vinyl ether.
