1.银饰变黑原因
银饰变黑是正常的自然现象,因空气和其它自然介质中的硫和氧化物等对银都有一定的腐蚀作用。银饰佩戴时间长了,硫与银结合就会在银饰表面形成一层黑色的硫化银膜,开始表现为一些细小的斑点,硫化现象加剧后慢慢扩散成片,形成人们通常所说的银垢,变成为黑色,影响到银饰的表面光泽,人们通常误以为是掉色。
其化学反应方程式为:4Ag+H2S+O2=2Ag2S+2H2O


2.银饰硫化后如何清洗?
挤少许牙膏,加少许水揉出丰富的泡沫,用软布擦拭直至光亮,缝隙可用细软毛牙刷刷净,再用清水冲净即可。对于复杂的构件和链子,可放入带泡沫的牙膏水中反复轻揉,再用清水冲净即可。硫化严重时,可用专业洗银水清洗。虽然进口洗银水号称是“不伤银”的,但是洗银水毕竟是化学制剂,不到必要时,建议不要选择使用。


3. 银饰日常如何保养?
较好的银饰保养方法是天天配戴,因为人体的油脂会使银发出温润自然的光泽(当 然也有人例外,有人的汗液中本身含有使银变黑的成分)。佩戴时每天要用软布或 擦银布擦拭银饰表面,以保持光泽及干燥。不佩戴时用软布轻拭表面以清除水分和 污垢,置放与密闭袋子中,防止银饰表面与空气接触而氧化变黑。
