有机气氛引起金属重量损耗和性能变坏的现象。如锌、镉上长“白霜”。有机气氛多来源于橡胶塑料、油漆、粘合剂、密封胶和木材等非金属材料。是木材及其他材料挥发出的有机酸(特别是甲酸和乙酸)、氯化氢、二氧化硫,叠氮酸、酚、膦、氨等。有机腐蚀的有利条件是密封包装容器内或通风不良的环境。有机气氛腐蚀的特点是,不同的非金属材料对金属产生的有机气氛腐蚀的程度也不同,如干性
The organic atmosphere causes the metal to lose weight and deteriorate the performance of the phenomenon. Such as zinc, cadmium on the long “hoar frost.” More organic atmosphere comes from rubber and plastics, paints, adhesives, sealants and wood and other non-metallic materials. It is organic acids (especially formic acid and acetic acid) volatilized from wood and other materials, hydrogen chloride, sulfur dioxide, azide, phenol, phosphine, ammonia and so on. The advantage of organic corrosion is to seal the environment inside the packaging container or poorly ventilated. Organic atmosphere corrosion is characterized by different non-metallic materials on the metal produced by the degree of corrosion of organic atmosphere is also different, such as dry
