本発明は螢光灯に封入して、水銀蒸気圧を制御する低融

回転冷却体に射出急冷して線状に形成する方法に関する
ものである。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for manufacturing a low melting point alloy wire for controlling mercury vapor pressure by enclosing it in a fluorescent lamp, and particularly relates to a method for manufacturing a low melting point alloy wire for controlling mercury vapor pressure from a nozzle in a molten state. This relates to a method of forming a linear material by injection quenching.
螢光灯などの低圧水銀蒸気放電灯は、その気密容器内に
おける水銀蒸気圧が６Ｘ１０−’〜７ Ｘ ］、 Ｏｍ
ｍＨｇで、比較的低い放電電流のときに供給電気エネル
ギーが水銀の２５３．７ ｎｍの紫外域放射線へ転換さ
れる効率が最も高くなることが知られている。A low-pressure mercury vapor discharge lamp such as a fluorescent lamp has a mercury vapor pressure in its airtight container of 6X10-' to 7X ], Om
mHg, it is known that the efficiency with which the supplied electrical energy is converted into mercury 253.7 nm ultraviolet radiation is highest at relatively low discharge currents.
上記２５３．７ ｎｍの紫外域の放射線は螢光体励起効
率が高いことから、上記６×１０〜
７Ｘ１０ｍ＋ｑＨｇに水銀蒸気圧を維持することが好ま
しく、このときの気密容器壁の温度は約４０℃である。Since radiation in the ultraviolet region of 253.7 nm has a high phosphor excitation efficiency, it is preferable to maintain the mercury vapor pressure at 6 x 10 to 7 x 10 m+qHg, and the temperature of the wall of the airtight container at this time is approximately 40°C. It is.
しかしながら、螢光灯などの低圧水銀〃ζ気故知、灯は
、近時Ｎｉ仔の細い気密容器壁の負荷が冒いものが増加
しておシ、気密容器壁の温度が高く、１００℃を越すも
のがある。However, in low-pressure mercury lamps such as fluorescent lamps, the load on the walls of narrow nickel airtight containers has increased in recent years, and the temperature of the walls of the airtight containers has been high, reaching temperatures of 100°C. There is something to overcome.
このように気密容器壁温度が高温になると、シ著しく筒
ぐなシ、放射された２’５３．７ｎｍ苓：主とする紫外
域の放射線が水銀によって自己吸収され、供給エネルギ
ーの紫外域放射線への転換効率が悪ぐなり、光出力が低
下する問題があった。When the wall temperature of the airtight container becomes high in this way, the radiated 2'53.7 nm radiation, which is mainly in the ultraviolet range, is self-absorbed by mercury and becomes the supplied energy of ultraviolet radiation. There was a problem that the conversion efficiency deteriorated and the light output decreased.
この対策としては、アマルガムを気密容器内に封入して
、高温時における水銀蒸気圧の上昇を抑制することが行
われるようになって＠た。As a countermeasure to this problem, amalgam has been sealed in an airtight container to suppress the rise in mercury vapor pressure at high temperatures.

３８５８２号公報などによって従来公表されている。For example, Hg and In, Lib At, Zn, Sn
, Pb, Bi, or Hg](i and Pb, t or Hg and Bi
A fluorescent lamp made of an alloy of PB and Sn for inserting amalgam was published in Japanese Patent Publication No. 33215, Publication No. 33215.
This has been previously published in Publication No. 38582 and the like.
気密容器にアマルガムを封入する方法は、内径が２０〜
２５胴φ程度の真空脱グミ用の細管から所定量を秤量し

ガムの方が、押開が容易で、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 to
A predetermined amount is weighed and sealed in a thin tube for vacuum degumming with a diameter of approximately 25 mm.For this purpose, a linear or plate-shaped amalgam is easier to push open and easier to insert through the thin tube. Therefore, it is industrially preferable.
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、通常の方法では線状あるいは板状に加工すること
が困難であった。However, since the above amalgam is mechanically fragile, it has been difficult to process it into a linear or plate shape using normal methods.
このため従来は、溶融したアマルガムをガスと共に噴射
して果粒状にするアトマイズ法あるいはインボラトラ機
械的に粉砕する方法などによって果粒状に形成し、これ
を秤量して気密容器に封入していた。For this reason, conventionally, molten amalgam has been formed into granules by an atomization method in which the amalgam is injected together with a gas to form granules, or by a mechanical crushing method using involatra, which is then weighed and sealed in an airtight container.
しかしながらアトマイズ法により得られたものは、粒径
や形状が不均一であシ、篩分けして粒径を調整しなけれ
ば秤量や細ちへの的。人ができないため、極めて歩留り
が悪く高価である。However, the particles obtained by the atomization method are non-uniform in particle size and shape, and if they are not sieved to adjust the particle size, they will be difficult to weigh and fine. Since it cannot be done by humans, the yield is extremely low and it is expensive.
捷たインゴットからの粉砕によるものは、同様に粒径や
形状が不均一であり、クラックがあってくだけ易く、シ
かもインゴットの中心部がＨｇリッチとなって組成のバ
ラツキが大きく、封入した場合の水銀蒸気圧の抑制効果
が一定しないほどの欠点があった。Those obtained by pulverization from shredded ingots are similarly uneven in particle size and shape, are prone to cracking, and may become Hg-rich in the center of the ingot, resulting in large compositional variations. The drawback was that the effect of suppressing mercury vapor pressure was inconsistent.

がかＩｔ Ｌぐ実用的ではない。In addition, as a technology for manufacturing all 71 metal plates, conventionally, Fe
There is a known method for manufacturing an amorphous a-alloy thin plate by injecting a molten % Q alloy consisting of Ni, etc., Si, and B into a cooling body that rotates at high speed. However, all of these alloys have a high melting point of around 1000°C or higher, and the groove plate obtained is extremely thin, about several tens of micrometers. Encapsulation from a capillary is extremely impractical.

とを目的とするものである。The present invention was made in view of the above points, and by applying the technology of manufacturing an amorphous p alloy thin plate, the plate thickness and wire diameter are 0.1 to 2.0 mm.
The object of the present invention is to provide a method for producing a low melting point alloy wire for use in fluorescent lamps, which is as large as a barrel, easy to weigh and insert, and has a uniform composition.

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通フの方法がある。In the present invention, 1 q of low-melting point alloy wire is produced in two ways: one is sealed in an airtight container with Hg and amalgamated in the container, and the other is injected and cooled the alloy containing Hg to produce amalgam alloy wire. There is a method.

It consists of I or 2 types, Bi and In, and its composition ratio is Sn 15-57%, Pb 5-40%,
The preferred range is B130 to 70% and In 4 to 50%.

悪くなる。As is clear from the graph, the amalgam alloy wire according to the present invention has a curve '1! As shown in A, the solid phase and liquid phase of amalgam coexist at a temperature range of 50 to 130°C, and in this state, the mercury vapor pressure is approximately 6 x 10-' to 7
It is possible to stably maintain the state with the highest optical output of X10-'y+unHg. On the other hand, FIG.
As shown by the curve Bi, in the case of a single injection, as the temperature rises, the mercury x C pressure rapidly rises, and the movement of the car deteriorates.

。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 material, such as quartz, which does not react with the alloy raw material 1. Furthermore, 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. There is.

に巻取る。In the above apparatus, first, the alloy raw material Iff is charged into the container 3 and heated by the electric heater 4 to melt it. When the predetermined temperature is reached, gas is injected from above the container 3, and the molten alloy raw material 1 is continuously injected from the nozzle 2 onto the surface of the rotary cooling body 5 by the gas pressure, and is rapidly cooled. An alloy wire 6 is formed and wound onto a spool (not shown).

けである。Furthermore, the rotational speed of the rotary cooling body 5 is preferably set within the range of 0.2 to 5.0+++/sec in order to obtain a plate embedment as thick as 0 to 2 mm. In this case, at a slow speed of less than 0.2 yn/sec, it is difficult to make the surface uniform, and the
At case speeds exceeding Oyn/sec, J9 becomes thinner than 0.1 mm, making it difficult to handle as a monthly injection phase. 5 Even if the injection pressure is increased, it will not become much thicker and will only spread wider in the width direction. .

ため均一なものが得られる。The thus obtained alloy wire 6u has no plate shape with a thickness of 01 to 2, and its composition is uniform because it is rapidly cooled from the active state.

きる。This alloy wire 6 can be cut into a predetermined length using a cutting machine, inserted into a fluorescent lamp airtight container starting from fine stones, and sealed as is, so there is no need for the conventional sieving process and the yield is reduced. It is easy to use, inexpensive, and easy to use, and can also improve workability.
