摘要: 镍白铜广泛用作饰品材料,其镍释放水平成为业界和消费者普遍关注的问题.文中以BZn10-25镍白铜为试验材料,按照EN1811的规定检测了材料在不同条件下的镍释放率.试验结果表明:合金的热处理状态、表面处理方式对材料的镍释放率有明显影响,100目石英砂喷砂面和高温淬火抛光面的镍释放率最高,中温退火抛光面最低;无论在何种状态下,BZn10-25镍白铜的镍释放率均远远超过镍指令规定的上限值,表明该材料用作饰品时容易引起镍过敏.

关键词: 饰品材料, 镍白铜, 镍释放, 热处理, 表面处理, 镍过敏

Abstract:

With the extensive use o nickel silver in jewelry manufacturing,the nickel release rate of this material has become a universal concern for jewelry industry and consumers.In this paper,BZn10-25 nickel silver was cho-senas the experimental material,and its nickel release rates under different conditions were tested according to the EN1811 standard.The results show that(1)the heat and surface treatment methods significantly affect the nickel release rate;(2)the sandblasting surface with 100-mesh quartz sand and the polishing surface under high-tempera-ture quenching are both of the highest nickel release rate,while the polishing surface under medium-temperature tempering is of the lowest rate;and(3)no matter what condition there is,the nickel release rate of BZn10-25 nickel silver is far more than the limit specified by the Nickel Directive,which means that the jewelry made with this material is likely to cause nickel allergy.

Key words: jewelry material, nickel silver, nickel release, heat treatment, surface treatment, nickel allergy
