のである。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for producing a low melting point alloy wire which is encapsulated in a fluorescent couple to control the vapor pressure of mercury, and in which the mercury is molten in the core and introduced into a refrigerant from a nozzle. The present invention relates to a method of forming a linear shape by injecting the same.

すものがある。A low-pressure mercury vapor number 'Li'l; lamp such as a fluorescent pair (bow-1) where the mercury vapor pressure in its airtight container is 6 x 10 to 7
In the case of i n-3 hood Hσ, the electric energy supplied is 253.7 n of mercury when the electric energy is relatively high.
It is known that the efficiency of conversion into ultraviolet radiation of m is the highest. Since the 253.7 nm ultraviolet radiation has a high phosphor excitation efficiency, the 6 x 10-
It is preferable to maintain the mercury vapor pressure at 3 to 7 x 10-3 + Hg, and the temperature of the wall of the airtight container at this time is about 40
It is ℃. However, in recent years, low-pressure mercury vapor discharge lamps such as fluorescent lamps have been increasingly used with small tube diameters and high load on the wall of the airtight container, and the temperature of the wall of the airtight container is high, exceeding 100° C. in some cases.

する問題があった。When the wall temperature of the airtight container becomes high in this way, the mercury vapor pressure inside the airtight container becomes significantly higher than 7 x 10-3 mHg, and the emitted radiation in the ultraviolet region, mainly at 253;7 nm, is caused by mercury. There is a problem that self-absorption occurs, resulting in poor conversion efficiency of supplied energy into ultraviolet radiation, resulting in a decrease in optical output.

板状のアマルガムの方が、秤量が容易で、細管からの挿
入も容易となるので工業的に好ましい。The method of enclosing amalgam in an airtight container is based on a method with a visual diameter of 2.
A predetermined amount is weighed and sealed from a vacuum degassing tube with a diameter of about 0 to 2.5 mm.For this purpose, linear or plate-shaped amalgam is easier to weigh and is easier to remove from a thin tube. It is industrially preferable because it is easy to insert.
しかしながら、上記のアマルガムは機械的に脆弱である
ため、通當の方法では線状あるいは板状に加工すること

果が一定しないなどの欠点があった。If the product is still crushed from an ingot, the particle size and shape are not uniform, and it is also prone to cracking.
However, the central part of the ingot is rich in Hg, resulting in large variations in composition, and the effect of suppressing mercury vapor pressure when encapsulated is inconsistent.

本発明において製造される低融点合金線は、Ｈｇと共に
気密容器に封入して、容器内でアマルガム化させるもの
と、Ｈｇを含む合金を射出冷却して、アマルガム合金線
を製造する２通の方法がある。The low-melting point alloy wire produced in the present invention can be produced by two methods: one is to seal it together with Hg in an airtight container and form amalgam in the container, and the other is to inject and cool the alloy containing Hg to produce an amalgam alloy wire. There is.

い状態に安定的に保持することができる。Here, Sn, Pb, Bi, and In are metals each having a low melting point, and moreover, form an amalgam with Hg and have the effect of lowering the melting point. By specifying the amounts of these alloy components added within the above ranges, 50 to 130
This is because an amalgam solid phase and liquid phase coexist state can be obtained in the temperature range of .degree. The graph in FIG. 1 shows the relationship between the wall surface temperature of the airtight container and the mercury vapor pressure when the amalgam alloy wire according to the present invention is sealed in the airtight container. As is clear from the graph, the amalgam alloy wire according to the present invention is
As shown in curve A, in the temperature range of 50 to 130°C, the solid phase and liquid phase coexist, and in this state the mercury vapor pressure is approximately 6 × 10 to 7 × 10. can be stably maintained in this state.

行き、効率が悪くなる。On the other hand, when Hg is enclosed alone, as shown by curve B, the mercury vapor pressure rapidly increases as the temperature rises, resulting in poor efficiency.
次に本発明の製造方法を第２図を参照して説明する。Next, the manufacturing method of the present invention will be explained with reference to FIG.
上記組成の低融点合金原料１を、先端にノズル２を設け

外周には高周波コイルあるいは電熱ヒーター４が設けら
れ、合金原料１を加熱溶融するようになっている。A low melting point alloy raw material 1 having the above composition is put into a container 3 having a nozzle 2 at its tip. This container 3 is made of a high melting point material such as quartz that does not react with the alloy raw material 1, and a high frequency coil or an electric heater 4 is provided around the outer periphery of the container 3 to heat and melt the alloy raw material 1.

合金線７は順次渦巻斌に巻回して重ねられて行く。In the above device, first, the alloy raw material 1 is put into the container 3,
Heat it with electric heater 4? 6 fA! '4) To make it into a state. When the temperature reaches a predetermined temperature, gas is injected from above the container 3, and 1 nozzle of the molten alloy raw material is continuously injected into the refrigerant 6 from the nozzle 2 by the gas pressure to rapidly cool it. An alloy wire 7 having a series of 1.A:L/ is obtained. In this case, by rotating the refrigerant container 5, the formed alloy wires 7 are sequentially wound into a spiral spiral and stacked one on top of the other.
なお、本発明においてノズル２の内径は０．３〜２．０
閾φが好ましく０．３ｍｍφ未満では連続的に射出でき
ず、また２、Ｏｍφを越えると合金線７の線径が不安定
となる。In addition, in the present invention, the inner diameter of the nozzle 2 is 0.3 to 2.0.
If the threshold φ is preferably less than 0.3 mmφ, continuous injection is not possible, and if it exceeds 2.0 mφ, the wire diameter of the alloy wire 7 becomes unstable.
またノズル２と冷媒容器５に入れた冷媒液面８との距離
は３０＋ｎｍ以下が好ましく、この距離が大きくなると
、連続した合金線７が得られず、また線径も不均一とな
る。Further, the distance between the nozzle 2 and the refrigerant liquid level 8 placed in the refrigerant container 5 is preferably 30+nm or less, and if this distance becomes large, a continuous alloy wire 7 cannot be obtained and the wire diameter will also become non-uniform.
溶融した合金原料１の射出温度は、合金原料１の融点よ
シ１０〜１００℃程度高い温度が好ましく、１０℃未満
では合金の流動性が悪く、また１００℃を越えると連続
した合金線７が安定して得られないからである。The injection temperature of the molten alloy raw material 1 is preferably about 10 to 100°C higher than the melting point of the alloy raw material 1. If it is less than 10°C, the fluidity of the alloy will be poor, and if it exceeds 100°C, the continuous alloy wire 7 will be This is because it cannot be obtained stably.
このようにして得られた合金線７は断面がほぼ円形で線
径も細く均一であり、しかも成分も溶融状態からの急冷
であるため均一なものが得られる。The alloy wire 7 thus obtained has a substantially circular cross section, a narrow wire diameter, and a uniform wire diameter. Furthermore, since the alloy wire 7 is rapidly cooled from a molten state, it is uniform in composition.
この合金線７は、切断機により所定必要量に切断して、
螢光好気密容器にそのまま封入することができるので、
従来の如き篩芥は作業が不要で歩留りが良く、安価であ
