METAL PLATE PERFORMANCE EVALUATING METHOD, AND METAL PLATE PERFORMANCE EVALUATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To evaluate an electromagnetic wave absorption property and a surface conductivity of a surface-treated coating of a metal plate by use of a metal plate performance evaluating apparatus for evaluating the electromagnetic wave absorption property of the metal plate.;SOLUTION: A Q-value of a housing 31 composed so as to bring the surface-treated coating 21 of the surface-treated steel plate 2 into contact with a frame 1 and a Q-value of a housing 32 composed so as not to bring the surface-treated coating 21 into contact with the frame 1 are measured by use of the metal plate performance evaluating apparatus for evaluating a performance of the metal plate. The electromagnetic wave absorption property and the surface conductivity of the surface-treated coating 21 are evaluated based on two Q-values.;COPYRIGHT: (C)2008,JPO&INPIT
