不同种类珍珠在各种外界环境下的抗腐蚀性研究

A study on the durability of different types of pearls in various external environments

通过对不同种类的珍珠进行加热、紫外线照射、汗液、沐浴露和防晒霜等腐蚀实验,分析了这些腐蚀手段对珍珠颜色和化学成分的影响。结果表明,加热对珍珠彩度降低的影响最小,而防晒霜和沐浴露的腐蚀效应最大。金珍珠在各种腐蚀手段下表现出最为明显的彩度下降。在珍珠腐蚀前后的化学成分分析中发现,各种腐蚀手段普遍导致珍珠表面Ca含量升高、Si含量显著降低。Mn和Sr的含量变化与珍珠种类和腐蚀手段相关。探究不同外界条件对珍珠色泽变化的影响,可为博物馆展览保存、消费者选购提供参考。

This study conducted corrosion experiments on different types of pearls,including heating,ultraviolet radiation,sweat,shower gel,and sunscreen,to analyze the effects of these corrosion methods on the color and chemical composition of pearls.The results show that heating has the least impact on the decrease of pearl color,while sunscreen and shower gel have the greatest corrosion effect.Gold pearls exhibit the most significant decrease in color under various corrosion methods.In the chemical composition analysis of pearls before and after corrosion,it was found that various corrosion methods generally led to an increase in Ca content and a significant decrease in Si content on the surface of pearls.The content changes of Mn and Sr are related to the type of pearl and the corro-sion method.Exploring the effects of different external conditions on the color changes of pearls can provide refer-ence for museum exhibitions and consumer purchases.
