Description
Technical field
The present invention relates to a kind of solid-state mercury alloys material, specifically be meant the bismuth indium mercury alloy that a kind of discharge light with low pressure gas is used.
Background technology
Discharge light with low pressure gas utilizes wavelength to produce visible light for ultra-violet sterilization or the excitated fluorescent powder of 253.7nm, ultraviolet ray near ordinary straight cast luminescent lamp wavelength 253.7nm mercury vapor pressure is 0.8Pa has the highest radiation efficiency, has the highest radiation efficiency for the ultraviolet ray of common compact fluorescent lamp wavelength 253.7nm mercury vapor pressure is 1.0Pa near.These class discharge light with low pressure gas pipe surface temperature height such as compact fluorescent lamp, electrodeless lamp, germicidal lamp, tubule footpath cold-cathode fluorescence lamp, at high temperature mercury vapor pressure is much larger than 1.0Pa for liquid mercury, and wavelength 253.7nm ultraviolet radiation efficient is low, and luminous efficiency is low.Obtain high light efficiency, must use control under comparatively high temps, stablize near the mercury alloys of mercury vapor pressure 1.0Pa, the mercury alloys that works in 70-125 ℃ at present generally adopts bismuth indium mercury alloy (replacing liquid mercury), bismuth indium mercury alloy is placed in the vapor pipe of lamp.
Generally adopting at present is that the traditional typical bismuth indium of bismuth indium mercury alloy mercury mass ratio is Bi: In: Hg=64: 31: 5, wherein the ratio of bismuth phosphide atom number is Bi: In=1.13: 1, the ratio of bismuth indium quality is Bi: In=2.1: 1, is 70-125 ℃ corresponding to light output from the working temperature zone that 88%-100% fluctuates continuously, mercury vapor pressure is about 0.3-3.0Pa, and liquid mercury has higher luminous efficiency relatively in this temperature province.But because of bismuth indium mercury alloy in medium temperature zone in 95-108 ℃, mercury vapor pressure can descend, drop to 0.3Pa, even it is lower, the part lamp is owing to the reason of discreteness, bismuth indium mercury alloy is in this temperature province, and making wavelength at the low excessively mercury vapor pressure of this temperature province is the efficient reduction of 253.7nm ultraviolet radiation, and luminous efficiency is low.Traditional bismuth indium mercury alloy has the working temperature zone of broad, but light output varies with temperature fluctuation greatly, and the photoelectric parameter discreteness of lamp is big.Another shortcoming of traditional bismuth indium mercury alloy is that alloy liquid phase point temperature is low, is melt into liquid fully at 110-120 ℃, easily flows.Tail Pipe Temperature height when justifying the gas exhauster automatic production in the system lamp process, bismuth indium mercury alloy is heated and can be melt into liquid and easily flows in the lamp, bismuth indium mercury alloy also can flow into from vapor pipe in the lamp when being higher than 110-120 ℃ in the lamp burning-point process, alloy is cooled to solid-state back easy tailor's chalk in back operation or transportation, cause the phosphor powder layer cut, come off, the alloy temperature and the original design alloy temperature that leaves in the vapor pipe that flow into simultaneously in the lamp are variant, the photoelectric parameter deterioration that causes lamp, although traditional bismuth indium mercury alloy can be worked 125 ℃ even higher, but, when surpassing 110 ℃ of temperature, work uses difficulty because the temperature of liquidus point has only 110 ℃.
The mass content of indium is all greater than 28% in traditional bismuth indium mercury alloy, be generally 31%, some content is higher, the mass content of indium is about 30% in the bismuth indium mercury alloy that U.S. Pat 4157485 proposes, the bismuth indium silver amalgam that international monopoly WO 02/097858 A1 proposes is to reduce indium content in bismuth indium mercury alloy, the mass content of indium is less than 30%, add silver in addition, can improve the liquidus point temperature of alloy, also can improve alloy in medium temperature zone 95-108 ℃ of mercury vapor pressure descend low excessively shortcoming, the consistence of lamp improves, but this scheme has reduced indium content, increased silver content, reach identical working temperature zone, must reduce mercury content, add alloy gross weight increase in the lamp, make troubles for the system lamp, also do not reduce cost.Number of patent application: the 200610036177.2 bismuth indium zinc amalgams that propose are to add zinc in bismuth indium mercury alloy, are in order to improve the liquidus point temperature of alloy, to improve the consistence of lamp.But it has also increased the higher metal of fusing point, brings certain difficulty for the manufacturing of alloy.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of in the working temperature zone mercuryvapour pressure energy more stably be controlled near the 1.0Pa, make light fixture have the output of light from 95%-100% continuously fluctuation, working temperature zone more stably, improve the liquidus point temperature of alloy simultaneously, reduce the flowability of alloy under 110-120 ℃, be applicable to the bismuth indium mercury alloy that discharge light with low pressure gas is used better.And because indium content reduces, the bismuth indium mercury alloy cost reduces.
The object of the present invention is achieved like this, is the alloy that contains bismuth indium mercury, and the mass ratio of bismuth indium mercury is: bismuth (Bi): indium (In): mercury (Hg)=66-82: 15-28: 3-8.
Bismuth indium mercury alloy of the present invention, can more stably control in the lamp mercury vapor pressure in the working temperature zone near 1.0Pa, make the high discharge light with low pressure gas of pipe surface temperature have more stable mercury vapor pressure at 70-110 ℃, thereby obtain higher luminous efficiency, improve stability, the consistence of product.Traditional bismuth indium mercury alloy and bismuth indium mercury alloy of the present invention light in compact fluorescent lamp are exported temperature variant rational curve and are seen Fig. 1, curve A is that bismuth indium mercury alloy light of the present invention is exported temperature variant rational curve, and curve B is that traditional bismuth indium mercury alloy light is exported temperature variant rational curve.
The present invention also can be above-mentioned bismuth indium mercury alloy by being aided with the polynary mercury alloys of bismuth indium that comprises lanthanum (La), cerium (Ce), zinc (Zn) silver (Ag), copper (Cu), iron (Fe), composition such as nickel (Ni) refractory metal of etc.ing, improve the startability of lamp, further improve the liquidus point temperature of alloy, reduce the flowability under the alloy high-temp.
The present invention can be dripped the method manufacturing of making the ball ball with the fusion of routine by behind the above-described alloy proportion, also can be with conventional die casting balling-up ball or cylindrical method manufacturing, also can be with conventional compacting balling-up ball or cylindrical method manufacturing.
