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.

Embodiment 1

[0008] A low-temperature amalgam consisting of alloy components with the following mass contents: Sn 75%, Sb 5%, Hg 20%.

[0009] After the above components are weighed, mixed, smelted and granulated, they can be applied to the manufacture of bare spot energy-saving lamps 2U, 3U and external spiral lamps (the amalgam is left in the exhaust pipe). In the feeder, the amalgam There will be no fuzz and adhesion; the amalgam can be smoothly placed in place when feeding, and there is no error phenomenon; the mercury will not be melted when it is sealed off, and the tube can obtain photoelectric characteristics close to pure mercury.

Embodiment 2

[0011] A low-temperature amalgam composed of alloy components with the following mass contents: Sn 61%, Sb 6%, Zn 3%, Hg 30%.

[0012] The above-mentioned amalgam materials can be applied to bare-point energy-saving lamps, 2D and ring lights, 2U, 3U, etc. built-in or external. During the lamp making process, the amalgam can withstand the vibration and friction of the feeder, will not hair and stick, rolls more smoothly, and has a high melting point, making it difficult to drop mercury in the lamp sealing process, and the lamp tube has an initial High brightness and stable photoelectric parameters and other advantages.

Embodiment 3

[0014] A low-temperature amalgam consisting of alloy components with the following mass contents: Sn 34%, Sb 20%, Zn 6%, Hg 40%.

[0015] The above-mentioned amalgam material can be applied to T4 and T5 straight tube fluorescent lamps, which can be installed externally or internally.

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 ...
