两类固汞在荧光灯中的应用

结合荧光灯用汞的发展趋势，从各个方面分析了裸灯和带罩灯对固汞特性的要求，提出了应用在荧光灯中的两类固汞，一种是符合汞有效率高、光通上升特性好、单粒含汞量少及颗粒含汞量偏差小这三方面要求的铋汞；另一种是符合不合Pb或Pb含量〈1000ppm、工作温度区域内汞蒸气接近最佳汞蒸气压、当汞合金失汞后，△T95与初始范围重叠的温度区域宽、汞合金的熔融温度高于或接近△T95的最高工作温度这四方面要求的铋铟锡汞，为荧光灯制造企业正确使用固汞提高产品质量、满足相关要求提供了有效的解决方案。

Applications of Two Types of Amalgams Used in Fluorescent Lamps

Combining with the development trend of mercury used for fluorescent lamps,we present two types of amalgams used for fluorescent lamps by analyzing the property requirements for the amalgam used in fluorescent lamps with cover and without cover in every way.One type is Bi-Hg with advantages: high mercury efficiency,good climbing performance of luminous flux,less mercury content in single grain and small mercury content deviation among the particles.The other is Bi-In-Sn-Hg with advantages: non-Pb or Pb cont...
