摘要
在热带以及亚热带服役的产品,受湿热环境的影响可能会出现各种问题.因此,需要在产品的研发周期内对产品进行湿热环境考核,以评估其耐湿热特性.而只有正确的执行湿热试验考核,才可以保证产品在湿热环境中可靠运行.本文首先介绍湿热原理及相关因素,从根本上理解湿热在产品上作用方式;随后,阐述湿热的影响效应以及潮湿环境对产品的影响、所导致的失效模式及失效机理;最后,阐述湿热试验的实验室模拟与实际环境的差异、湿热试验的种类以及进行湿热试验需要采取何种标准和各标准之间的差异.通过对湿热的概念及原理的介绍,湿热导致的失效模式及失效机理,乃至湿热试验的类型及标准的选用,为产品进行耐湿热的设计及湿热试验的考核提供参考.
Abstract
Products serving in the tropics and subtropics may have problems under the influence of a warm and humid environments.Therefore,it is necessary to conduct a warm and humid environment assessment during the product development cycle to evaluate its moisture and heat resistance.Only the correct execution of the damp heat test can ensure the reliable operation of the product in the hot and humid environment.This paper first introduces the principle of damp heat and related factors,and fundamentally understands the action mode of damp heat on products;Then,the effect of dampness and heat,the influence of humid environment on the product,the failure mode and failure mechanism are expounded.At last,the differences between laboratory simulation and actual environment,the types of wet heat tests,the standards to be adopted and the differences among them are expounded.Through the introduction of the concept and principle of damp and heat,the failure mode and failure mechanism caused by damp and heat,as well as the selection of the types and standards of damp and heat test,the reference is provided for the design of damp and heat resistance of products and the assessment of damp heat test.
