ADHESIVE STRENGTH EVALUATION METHOD AND ADHESIVE STRENGTH EVALUATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive strength evaluation method and an adhesive strength evaluation device which reproduce a phenomenon of peeling of an adherend from an outer surface of a buried pipe in a relatively faithful manner.;SOLUTION: An adhesive strength evaluation method executes the following steps in this order: an interposing step of interposing a long member 10 between an adhesive surface of a test piece S and an adherend 30 in a state of allowing both ends 10a, 10b in a longitudinal direction to be exposed from between the adhesive surface of the test piece S and the adherend 30; a bonding step of bonding the adhesive surface of the test piece S and the adherend 30 with an adhesive 31 in such a state that the long member 10 is interposed; and a peeling force applying step of applying peeling force for peeling the adherend 30 from the adhesive surface of the test piece S by pulling at least either both ends 10a, 10b of the long member 10 or the test piece S in a manner to peel the adherend 30 from the adhesive surface of the test piece S.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
