Low temperature amalgam suitable to round arranged machine

Abstract

This invention discloses low-temperature amalgam for round exhaust. The low-temperature amalgam is composed of: Sn 15.5-79.5 wt.%, Sb 0.5-20 wt.%, Zn 0-20 wt.%, Cu 0-5 wt.% and Hg 18-60 wt.%. Compared with present techniques, the low-temperature amalgam in this invention has such advantages as accurate spherical body, high surface hardness and mechanical hardness, high melting point, difficult Hg volatilization and precipitation, smooth rolling and high friction tolerance, and is suitable for manufacturing lamp using round exhaust with satisfying photoelectric indexes.

Description

technical field [0001] The invention relates to an alloy material, in particular to an amalgam material used in the manufacture of fluorescent lamps. Background technique [0002] Mercury is a necessary and irreplaceable material in low-pressure mercury lamps such as fluorescent lamps, energy-saving lamps, ultraviolet germicidal lamps, and electrodeless lamps. However, mercury is also recognized as a highly polluting material. In order to protect the environment, actively respond to the EU's "RoHs" directive, and promote green lighting, it is necessary to effectively reduce the pollution of mercury to the environment. Using solid mercury (amalgam) to replace liquid mercury can be strictly Controlling the amount of mercury used can reduce the loss and evaporation of liquid mercury, which can have a good environmental protection effect. [0003] At present, low-temperature amalgams such as ZnHg, ZnSnHg, AgCuSnHg, and SnHg have been gradually adopted in ordinary straight tube ...

AI Technical Summary

Problems solved by technology

However, with the large-scale application of "circular row cars", various amalgams in the prior art have exposed defects that cannot withstand friction and vibration in the feeder and during the sealing and separation process, and are easily The reason for this defect is that the existing amalgam has a low melting point, low surface hardness and mechanical hardness, and the surface tension of the alloy after melting is low.
