摘要
电器电子产品零部件的剩余寿命评估是一项具有较高社会应用价值的工作。循环经济背景下,人们通过追求增加产品价值、优化资源利用和减少环境影响实现可持续发展。而旧电器电子产品的可再制造性评价、产品系统生态效率评估、政府对旧品的市场准入和监管都与产品零部件的剩余寿命密切相关。因此准确评估产品零部件的剩余寿命是上述工作的前提,具有重要现实意义。通过选取已使用阶梯工作时间的典型样品,采用失效分析检测方法,探讨微观缺陷变化规律对零部件寿命阶段判定的可能性,归纳对寿命缺陷较敏感的检测手段,总结相关检测技术的有效性。期望对政府监管、产品废旧属性鉴定,相关产品零部件可制造性评价等领域具有借鉴和参考作用。
The remaining life assessment of electrical and electronic products parts is a work with high social application value.In the context of circular economy,people achieve sustainable development through the pursuit of increasing product value,optimizing resource utilization and reducing environmental impact.The remanufacturability evaluation of used electrical and electronic products,product system eco-efficiency evaluation,and government’s market access and supervision of used products are all closely related to the remaining life of the product parts.Therefore,accurate assessment of the remaining life of the product parts is the prerequisite for the above work,it has important practical significance.Selects typical samples that have used stepped working hours and adopts failure analysis detection methods to explore the possibility of micro-defect change rules in determining the life stage of parts,summarizes the detection methods that are more sensitive to life defects,and summarizes the effectiveness of related detection technologies.It is expected to be used for reference and reference in the fields of government supervision,product waste attribute identification,and manufacturability evaluation of related product parts.
