Solid mercury with high content

Abstract

The invention opened solid hydrargyrum belong to amalgam field. The weight content is: Hg 20%-65%, Sn 5%-74.5%, Zn 5%-35%, Ag 0.5%-10%, Ga 0%-10%, In 0%-10%. The solid Hg has the wide range of the Hg%, even it includes 60% Hg, it keeps the solid in the room temperature. It can be used to make the fluorescent lamp. The strip lamp has the good low-temperature characteristics and has the high brightness. Also it can use the light Hg grain, so it can decrease the damage to the fluorescent layer. The fluorescent lamp includes power saving fluorescent lamps, bactericidal lamp.

Description

technical field [0001] The invention relates to an alloy material, in particular to an amalgam material used for making fluorescent lamps. Background technique [0002] At present, in fluorescent lamps (including energy-saving lamps, electrodeless lamps, germicidal lamps, etc.), mercury cannot be replaced by other substances at present, but mercury is likely to cause serious environmental pollution problems, and solid mercury (solid amalgam) is used instead of liquid Mercury can overcome the defects that liquid mercury is easy to lose, difficult to control, and difficult to recycle, so it can play a role in environmental protection. However, due to the low Hg content of fluorescent lamp tubes made of traditional solid mercury such as ZnHg or ZnSnHg, the tubes have the disadvantages of poor low-temperature start-up performance, low instantaneous brightness, and slow light-up. The mercury ball particles are relatively heavy, and the lamp tube is easy to scratch the phosphor c...

[0002] At present, in fluorescent lamps (including energy-saving lamps, electrodeless lamps, germicidal lamps, etc.), mercury cannot be replaced by other substances at present, but mercury is likely to cause serious environmental pollution problems, and solid mercury (solid amalgam) is used instead of liquid Mercury can overcome the defects that liquid mercury is easy to lose, difficult to control, and difficult to recycle, so it can play a role in environmental protection

However, due to the low Hg content of fluorescent lamp tubes made of traditional solid mercury such as ZnHg or ZnSnHg, the tubes have the disadvantages of poor low-temperature start-up performance, low instantaneous brightness, and slow light-up. The mercury ball particles are relatively heavy, and the lamp tube is easy to scratch the phosphor coating during transportation; due to the limitation of the formula, the "saturation" of the existing amalgam is low, and when the mercury content exceeds 50%, it will occur Adhesion, the amalgam changes from solid state to solid solution state at room temperature, and mercury atoms will be ejected from the surface, resulting in amalgam adhesion phenomenon, which not only affects the environmental protection effect, but also brings difficulties to the lamp making process
