Japanese Patent JP2023085735
Kind Code:
A
Abstract:
To provide an evaluation method, evaluation system and evaluation program of a cross-linked state of cross-linked rubber which exactly grasp the cross-linked state for an actual network structure.SOLUTION: An evaluation method of a cross-linked state of cross-linked rubber acquires image data 30 of an ultra-thin section 20 of cross-linked rubber fixed by a network structure swelled by a transmission electron microscope 2, acquires line image data 35 in which a molecular chain constituting the network structure in the image data 30 is specified and displayed by performing data processing of the image data 30 by a calculation device 3, calculates a branch point 38 and a branch length in the molecular chain of the line image data 30, and evaluates the cross-linked state on the basis of the calculated number of branch points 38 and branch length.SELECTED DRAWING: Figure 2
