摘　　要：电蒸炉开发中出现玻璃发白腐蚀问题,玻璃坚硬、光滑、易清洁的特点,常识均会认为玻璃不会腐蚀。通过分析测试研究,找到门内玻璃发白腐蚀的原因和解决方法。如下详细说明玻璃发白腐蚀的分析过程和方法。采用多种高精仪器设备测试分析:聚焦离子束FIB切面加工分析、超高倍数显微镜观察和能谱仪化学成份分析,从实际测试和理论基础多角度研究分析。玻璃发白腐蚀主要是电蒸炉模拟烹饪老化过程,玻璃表面有杂点、损伤、异物附着,玻璃长期处于高温高湿环境,催化加速了玻璃的表面的水解反应,导致玻璃腐蚀。防止玻璃腐蚀水解应定期玻璃清洁玻璃表面,阻断水解反应。玻璃安装过程表面刮花,膜层损伤,更容易被腐蚀,应加严玻璃的外观检查。In the development of electric steaming furnace,the problem of glass whitening corrosion occurs.The glass is hard,smooth and easy to clean,and common sense will think that the glass will not corrosion.By analyzing and testing,the causes and solutions of white corrosion of glass inside the door are found.The analysis process and method for glazing corrosion are described in detail below.A variety of high-precision instruments and equipment were used for testing and analysis:FIB section processing analysis of focused ion beam,ultra-high power microscope observation and analysis of energy spectrum components.The analysis was carried out from various angles of practical testing and theoretical basis.The glass whitening corrosion is mainly caused by the cooking aging process simulated by the electric steam furnace.There are miscellaneous spots,damage and foreign matter attachment on the glass surface.The glass is in a high temperature and high humidity environment for a long time,which catalyzes the hydrolysis reaction of the glass surface and leads to glass corrosion.To prevent glass corrosion hydrolysis,the glass surface should be cleaned regularly to block the hydrolysis reaction.During the installation process,the surface of the glass is scratched,the film layer is damaged,and it is easier to be corroded.Therefore,the appearance inspection of the glass should be strictly enforced.
