Product Details
深圳讯科标准气体腐蚀检测
一、测试目的和意义:  
    大多数产品所使用的环境都是在大气中,而大多数的腐蚀发生在大气环境中,大气中含有氧气、湿度、温度变化和污染物等腐蚀成分和腐蚀因素。大气环境导致金属表面形成水膜,在大气中存在H2S、SO2、NO2、Cl2等有害气体溶入金属表面上所形成的水膜中,作为腐蚀性离子从而加速腐蚀进程。 
    在一定的温度和湿度的环境下,利用H2S、SO2、NO2、Cl2等有害气体对材料或产品进行加速腐蚀,重现材料或产品在一定时间范围内所遭受的破坏程度。考核材料及防护层的抗气体腐蚀的能力,以及相似防护层的工艺质量比较,也可以用来考核某些产品的抗气体腐蚀的能力。
二、测试应用范围: 
    通信产品及周边零部件、汽车电子、电子元器件、连接件、金属材料、电子电工等产品的防护层以及电子电工产品。
