Study on improvement of reliability and durability of industrial commodity with active protection

按原计划用劣化分析方法对聚合物材料的疲劳发展和降解进行了实验研究。将人造材料与天然材料进行比较，并将其应用于传统商品，是本研究的主要研究内容之一。在上述两项工作的基础上，通过实验和测量的配合，对具有复杂复杂系统的功能产品的可靠性进行了考察，并提出了“环境时代”超长寿命材料的概念。人工高分子材料热降解的定量研究方法通过对使DPC成为模型材料的定量考察和热疲劳过程中分子量的变化，得出了热降解的定量结果。结果，短期…获得了令人满意的定额结果1.通过以GC/MS为中心的测量以及建立数据处理方法等限值要求，对高分子链的裂解、热性能和光学劣化等进行了测量。人工聚合物材料的劣化研究利用“加速热循环试验机”测试了聚合物材料的疲劳性能。结果表明，聚合物的相对分子质量和结构随循环次数的变化而变化。指出聚合物材料的寿命预测是困难的，因为聚合物材料的疲劳现象与分子链和分子结构相互缠绕的复杂性有关。此外，由于所研究的热解、光学劣化和力学劣化等原因，进一步阐明了这是一种主链断裂，并且在每一次劣化中都能发生构象变化直到切割。传统材料在自然界中的保护作用以及对传统材料的调查和检验人们已经认识到，在生物和传统材料中，它往往不同于人造产品和部件。例如，自修复系统的开发，初步材料的制备，随着使用可靠性比第一次提高更多；近年来，特别是劣化定量评估技术的开发，修复系统的性质研究，以及疲劳构象变化的检测。较少

The development of the fatigue and the degradation of polymeric materials have been experimentally achieved by the analytical method of the deterioration according to the initial plan. The man-made materials were compared with the materials in nature and used in the traditional goods as one of the main research works in this study. In the addition to above two works, the reliability of functional goods which are constructed with sophisticated and complicated system has been surveyed and the concept of the materials which have ultra long lives for "Environmental era" by the cooperation of the experiments and the survey.1. Quantitative research technique of heat degradation of artificial polymeric materialsThe result of the quantification of deterioration was achieved from the examination of the fixed quantity that made DPC a model material and the change in molecular weight in the thermal fatigue process. As a result, it came to obtain a satisfactory fixed quantity about the short-term … More collapse of polymer chains of thermal and optical deterioration, etc.by measurement that centered on the GC/MS and establishing the data processing method such as limitary requirement.2. Deterioration research on artificial polymeric materialsThe fatigue behavior of polymeric material was examined by using "accelerated thermal cyclic tester". As a result, the change of the molecular weight and the change of the structure that depended on number of cycle were seen. It was clarified that the longevity forecast of the polymeric materials was difficult because the fatigue phenomenon of the polymeric materials is related to the complexity of intertwining of molecular chain and molecular structures. Moreover, it was clarified that it was a main chain scission and there was able to be a conformational change up to cutting in each deterioration because of researched pyrolysis, optical deterioration, and the mechanics deterioration, etc3. Protection function in the nature, and investigation and examination of traditional materialsIt has been understood to tend to differ from artificial products and parts in the living thing and the traditional materials. For example, the self-repairing system develops, a preliminary material is prepared, reliability rises more than the first with use.At current year, Development of quantitative evaluation technique of deterioration, investigation of repairing system in nature, and examination of conformational change by fatigue were especially done.
