AI Technical Summary

Technical Problem

Existing methods for recycling resin waste materials do not effectively grasp the state of the resin, particularly for resins like polypropylene, limiting the ability to restore their performance.

Method used

A state grasping system and method that includes an acquisition unit for data analysis, an extraction unit for feature quantity extraction, and a grasping unit to determine the resin's state using models, enabling the evaluation of resin properties such as tensile mechanical properties without requiring shape-specific processing.

Benefits of technology

Enables efficient and cost-effective evaluation of resin states, allowing for the restoration of mechanical properties in recycled resins, particularly polypropylene, by grasping features like tensile elastic modulus, yield stress, and yield strain.

Abstract

To provide a state grasping system capable of grasping the state of resin.SOLUTION: A state grasping system 10 includes: an acquisition unit 4 for acquiring data on a feature amount related to the state of resin by analyzing a target object containing the resin; an extraction unit 5 for extracting the feature amount from the data acquired by the acquisition unit 4; a grasping unit 6 for grasping the state of the resin from the feature amount extracted by the extraction unit 5 and a state grasping model for grasping the state; and an output unit 2 for outputting at least one of the result of grasping by the grasping unit 6 and information obtained by the result of the grasping.SELECTED DRAWING: Figure 1
