Novel low-temperature amalgam

Abstract

The invention discloses a novel low-temperature amalgam which comprises an inner core, wherein a Hg-Zn alloy surface layer is coated on the surface of the inner core. Compared with the traditional low-temperature amalgam, the novel low-temperature amalgam has the outstanding advantages that the release speed of mercury atoms of the novel low-temperature amalgam in a light tube is obviously higher than that of the traditional low-temperature amalgam and the climbing time of the light tube is short since the mercury atoms of the novel low-temperature amalgam are evenly distributed at the part of the Hg-Zn alloy surface layer; meanwhile, the mercury consumption of a fluorescent light tube can be decreased effectively and pollution is reduced; and therefore, the novel low-temperature amalgam has good practical applicability and can generate favorable economic and social benefits.

Description

technical field [0001] The invention relates to a low-temperature amalgam, in particular to a novel low-temperature amalgam. Background technique [0002] Fluorescent lamps belong to low-pressure gas discharge lamps. They rely on ultraviolet rays generated by mercury atom vapor discharge to excite phosphors to emit visible light. Mercury is a toxic and harmful substance. create pollution. Resource conservation and environmental protection are issues that all countries in the world attach great importance to. The problem of mercury pollution in fluorescent lamps is attracting more and more attention. Research on methods to further reduce the amount of mercury used in fluorescent lamps will directly affect the development of fluorescent lamps in the future. [0003] Theoretically, the mercury used by fluorescent lamps to maintain the discharge process is very limited, only tens of micrograms, but the actual amount of mercury used far exceeds the required amount, and the actu...

Problems solved by technology

[0004] Although traditional low-temperature amalgam has played a positive role in reducing mercury pollution and protecting the environment, with the further increase in the EU's requirements for the amount of mercury used in straight-tube fluorescent lamps such as T5, the further use of traditional low-temperature amalgam has exposed major defects. , that is, the T5 straight tube fluorescent lamp using traditional low-temperature amalgam is very slow to light up, that is, the rising time becomes very long. In the future, the low-pressure mercury discharge lamp requires that its mercury content be further greatly reduced, and it is also required to light up quickly. This traditional low-temperature amalgam can no longer meet this new requirement
