海水养殖珍珠的漂白技术研究

通过对漂白体系中溶剂、表面活性剂、双氧水浓度3个重要参数的优化选择,研究了海水养殖珍珠的漂白技术。首次发现在海水养殖珍珠漂白过程中,以海水为介质漂白效果明显优于用甲醇、乙醇、丙酮和蒸馏水。在以海水为介质的漂白体系中,表面活性剂贝芬家用洗手液使用效果较优,双氧水体积分数为5%,效果最佳。同时探讨了漂白时间对珍珠长麻的影响。

The study on bleaching technique of seawater cultivated pearl

The bleaching conditions for bleaching the seawater cultivated pearls have been investigated.For the first time,seawater was used in bleaching seawater cultivated pearls as solvent,which showed better qualities than methanol, ethanol,acetone and distilled water.When the solvent was seawater,the surfactant of Befit hand cleanser should be chosen preferentially,and the best concentration of hydrogen peroxide was 5%.The influence of bleaching time on the stain growth of pearl has also been discussed in this paper.
