Abstract
The invention discloses solid mercury, belonging to the technical field of lamp manufacturing materials. The solid mercury is SnZnHg alloy, comprising Sn, Zn and Hg, wherein the weight content of Hg accounts for 40-60% of the weight of the SnZnHg alloy; and the weight content of Zn accounts for 5-15% in the SnZn alloy with the exception of Hg. The solid mercury obtained in the invention is relatively stable at normal temperature, no mercury vapor releases outward, and no liquid mercury is separated out from surface, thereby ensuring the security and reliability of the lamp manufacturing process; after Hg is released, the recrystallization temperature of SnZn alloy is below 200 DEG C, SnZn alloy is recrystallized, and crystal lattice recombination fills in the regression gap of Hg atom, thereby stopping the occurrence of return suction phenomenon of Hg atom; the solid mercury can lower the difficulty in lamp making technology and reduces energy consumption; and the manufactured energy-saving lamps have good startup property and can quickly reach maximum brightness.
Description
Technical field
The present invention relates to a kind of manufactured materials of electricity-saving lamp, particularly a kind of amalgam material.
Background technology
The principle of work of electricity-saving lamp mainly is to heat to tube filament through barretter, and when the 1160K temperature, filament just begins emitting electrons greatly; The electronic impact ar atmo produces radiative collision, has obtained energy after the ar atmo collision and has clashed into mercury atom again, and mercury atom transition after absorbing energy produces ionization; Send the ultraviolet ray of 253.7nm, ultraviolet ray excited light-emitting phosphor, the temperature of filament is about 1160K during owing to work; Temperature 2200K-2700K than incandescent light work is much lower; So the also big raising of its life-span reached more than 5000 hours, because there is not the such heating effect of current of incandescent light in it; The effciency of energy transfer of fluorescent material is also very high, reaches more than every watt 50 lumen.Owing to need use mercury in the electricity-saving lamp, pure mercury is liquid and is easy to the evaporable toxic substance, can cause damage to environment and human body, therefore; When the system lamp, people adopt a kind of solid-state amalgam material, and this amalgam material is mercurous alloy material, and it is solid-state at normal temperatures; Claim again " Gu mercury ", after processing electricity-saving lamp, need toast; Mercury is separated out from alloy, form that mercuryvapour is full of the fluorescent tube of sealing or in fluorescent tube, form pure mercury, but when fluorescent tube at normal temperatures after the long storage time; The mercury atom of separating out can return gradually in the solid-state alloy and go, and causes the starting characteristic variation of fluorescent tube, the shortcoming that lamp tube starting is slow.For overcoming above-mentioned defective, must adopt the high bake amalgam, after mercury atom is separated out; The lattice of alloy is changed, and recrystallization destroys the regressive space of mercury atom, reaches the generation that stops mercury resorption phenomenon; At present, the solid mercury that recrystallization temperature is minimum in the world is SnHg50, and wherein the weight content of Sn, Hg is 50%; Its recrystallization temperature is 231 ℃, and storing temperature is about 280-320 ℃.In the bake process, temperature is high more, and the energy of consumption is many more; Simultaneously, also make lamp manufacturing process become comparatively difficult, because; The pyritous baking need be considered the temperature resistant capability of other parts of fluorescent tube, and in the fluorescent tube behind the gas expansion, factors such as the pressure tolerance of fluorescent tube.
Summary of the invention
The purpose of this invention is to provide a kind of solid mercury, with the difficulty of reduction lamp manufacturing process, and save energy.
The objective of the invention is to realize like this: a kind of solid mercury, the SnZnHg alloy for being made up of Sn, Zn, Hg is characterized in that: wherein, the weight content of Hg is the 40-50% of SnZnHg weight alloy; Among Sn beyond the removal of mercury, the Zn, the weight content of Zn is 5-10%.
As preferred version of the present invention, the weight content of said Zn in Sn, Zn is 8.8%.
As preferred version of the present invention, said SnZnHg alloy is Sn45.5Zn4.5Hg.
The solid mercury that the present invention obtained when mercury weight content during at 40-50%, can guarantee that alloy is comparatively stable at normal temperatures, and no mercuryvapour outwards discharges, and does not also have liquid mercury and separates out from the surface, has guaranteed that system lamp process safe is reliable; After mercury disengaged, the recrystallization temperature of SnZn alloy was below 200 ℃, and mercury all disengages when this temperature, therefore; After processing electricity-saving lamp,, can guarantee that mercury all separates out, afterwards as long as the temperature of baking is higher than 200 ℃ in theory; The SnZn alloy recrystallization, its alloying pellet obviously reduces than SnZnHg alloying pellet, and crystal lattice recombination is filled up the regressive space of mercury atom, can stop the generation of mercury atom resorption phenomenon fully; Beneficial effect of the present invention is: can reduce the difficulty in the lamp manufacturing process, improve system characteristic of a navigation light amount, reduce energy consumption; The starting characteristic of the electricity-saving lamp of processing is good, and start time is short, and fluorescent tube can reach high-high brightness rapidly.
