Low temperature amalgam suitable to round arranged machine

Abstract

The invention discloses a low-temperature amalgam suitable for the process of making circular car lamps in the field of amalgam materials used in the manufacture of fluorescent lamps. It is composed of alloy components with the following mass content: Sn 15.5%-79.5%, Sb 0.5% -20%, Zn 0%-20%, Cu0%-5%, Hg18%-60%. Compared with the prior art, the low-temperature amalgam of the present invention has the most accurate sphere, the surface hardness and mechanical hardness of the alloy are high, the melting point is high, the mercury is not easy to volatilize and precipitate, and it can withstand the pressure of the feeder during the lamp making process. Vibration and friction, no hair and adhesion, smoother rolling, and high melting point, so that mercury is not easy to drop when the lamp is sealed and separated, and the lamp tube can obtain relatively satisfactory photoelectric parameters. The invention is particularly suitable for the application of round row car lamps.

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.
