Definitions
- the invention relates to amalgam beads for the introduction of mercury in modern energy-saving lamps.
- Modern energy-saving lamps of the TFL (Tube Fluorescent Lamp) or CFL (Compact Fluorescent Lamp) type belong to the low-pressure gas discharge lamps. They consist of a gas discharge flask filled with a mixture of mercury vapor and argon and internally coated with a fluorescent phosphor. The ultraviolet radiation of mercury emitted during operation is converted from fluorescence coating to visible light by the phosphor coating. The lamps are therefore also referred to as fluorescent lamps.
- the mercury required for the operation of the lamps was formerly metered as liquid metal into the gas discharge flask.
- the US 4,145,634 describes the use of Amalgampellets with 36 at% indium, which contain high liquid content even at room temperature because of the high mercury content.
- the pellets tend to stick together when they get in contact with each other. By coating the pellets with suitable materials in powder form, this can be prevented.
- Stable metal oxides titanium oxide, zirconium oxide, silica, magnesia and alumina
- graphite glass powder
- phosphors phosphors
- borax antimony oxide
- metal powders that do not form an amalgam with mercury (aluminum, iron and chromium) are suggested.
- the WO 94/18692 describes the use of pellets of zinc amalgam with 5 to 60, preferably 40 to 60 wt.%, of mercury.
- For the production of spheroid Amalgampellets is in the US 4,216,178 described method used in which the molten amalgam by a vibrated spout nozzle into small Drop is divided and cooled in a cooling medium below the solidification temperature.
- the pellets are in accordance with WO 94/18692 not coated.
- amalgam balls from the melt the amalgam must be heated to a temperature at which the amalgam is completely melted. This is guaranteed with a zinc amalgam only at a temperature above 420 ° C with certainty. These high processing temperatures necessitate corresponding safety precautions because of the high mercury vapor pressure due to the toxicity of the mercury.
- the JP 2000251836 describes the use of amalgam cells of tin amalgam for the production of fluorescent lamps.
- the tin amalgam preferably has only a low mercury content with a tin / mercury atomic ratio of between 90-80: 10-20. This corresponds to a mercury content of 15.8 to 29.7 wt .-%.
- the JP 2000251836 Does not give any information about how the amalgam spherical pellets are made.
- amalgam balls of a Zinnamalgam which has a mercury content between 30 and 70 wt .-%.
- the amalgam spheres preferably have a mercury content of from 30 to 60 and in particular from 40 to 55% by weight.
- the balls can look like one in the EP 1381485 B1 described method are prepared from a melt of the amalgam. This is completely melted Amalgam dripped into a cooling medium with a temperature below the solidification temperature of the amalgam. It is advantageous here that Zinnamalgame completely melt even at temperatures below 230 ° C. The expense of ensuring job security in the production of tin amalgam balls is therefore significantly lower than in the case of zinc amalgam balls.
- amalgam spheres with diameters between 50 and 2000, preferably between 500 and 1500 microns are suitable.
- the tendency of the amalgam beads to stick together can be inhibited if the balls are coated with a powder of a metal which forms an amalgam with mercury. Due to the amalgamation of the metal powder, a surface layer with a low mercury content is formed on the spheres, which no longer contains any liquid phases at the usual processing temperatures of the amalgam spheres and thus prevents the adhesion tendency from the untreated spheres.
- the metal powder used for the coating should not contain particles with a grain diameter greater than 100 ⁇ m. Particles with larger grain diameters amalgamate only incomplete and lead to a rough surface of the balls, which makes it difficult to meter the balls. Preference is given to using a metal powder whose powder particles have a particle diameter of less than 80 ⁇ m. As suitable metals, tin and zinc have been found. Tin is preferred.
- the balls can be presented, for example, in a rotating vessel and sprinkled with constant circulation with the metal powder until no sticking of the balls is more detectable.
- the following table shows calculated values for the total mass (Sn + Hg) and the mercury mass (Hg) of tin amalgam spheres depending on the diameter of the spheres and for tin amalgams with mercury contents between 20 and 50 wt .-%.
- the table also shows the densities ⁇ of the different amalgams used in the calculations.
- amalgam spheres made from a SnHg50 containing 50% by weight of mercury contain about three times the mass of mercury, such as amalgam spheres made of SnHg20 with only 20% by weight of mercury.

Abstract
Description
Die Erfindung betrifft Amalgamkugeln für die Einbringung von Quecksilber in moderne Energiesparlampen.The invention relates to amalgam beads for the introduction of mercury in modern energy-saving lamps.
Moderne Energiesparlampen vom TFL- (Tube Fluorescent Lamp) oder CFL-Typ (Compact Fluorescent Lamp) gehören zu den Niederdruck-Gasentladungslampen. Sie bestehen aus einem Gasentladungskolben, der mit einer Mischung aus Quecksilberdampf und Argon befüllt und innen mit einem fluoreszierenden Leuchtstoff beschichtet ist. Die im Betrieb emittierte Ultraviolettstrahlung des Quecksilbers wird von der Leuchtstoff-Beschichtung durch Fluoreszenz in sichtbares Licht umgewandelt. Die Lampen werden daher auch als Fluoreszenzlampen bezeichnet.Modern energy-saving lamps of the TFL (Tube Fluorescent Lamp) or CFL (Compact Fluorescent Lamp) type belong to the low-pressure gas discharge lamps. They consist of a gas discharge flask filled with a mixture of mercury vapor and argon and internally coated with a fluorescent phosphor. The ultraviolet radiation of mercury emitted during operation is converted from fluorescence coating to visible light by the phosphor coating. The lamps are therefore also referred to as fluorescent lamps.
Das für den Betrieb der Lampen benötigte Quecksilber wurde früher als flüssiges Metall in die Gasentladungskolben dosiert. Seit langem ist es jedoch bekannt, das Quecksilber in Form von Amalgamkugeln in die Gasentladungskolben einzubringen. Dies erleichtert die Handhabung des toxischen Quecksilbers und erhöht die Genauigkeit der Dosierung.The mercury required for the operation of the lamps was formerly metered as liquid metal into the gas discharge flask. For a long time, however, it has been known to introduce the mercury in the form of amalgam balls into the gas discharge pistons. This facilitates the handling of the toxic mercury and increases the accuracy of the dosage.

Zur Herstellung von Amalgamkugeln aus der Schmelze muß das Amalgam auf eine Temperatur erwärmt werden, bei der das Amalgam vollständig aufgeschmolzen ist. Das ist bei einem Zinkamalgam erst bei einer Temperatur oberhalb von 420 °C mit Sicherheit gewährleistet. Diese hohen Verarbeitungstemperaturen machen wegen des damit verbundenen hohen Dampfdrucks von Quecksilber entsprechende Sicherheitsvorkehrungen wegen der Toxizität des Quecksilbers notwendig.For the production of amalgam balls from the melt, the amalgam must be heated to a temperature at which the amalgam is completely melted. This is guaranteed with a zinc amalgam only at a temperature above 420 ° C with certainty. These high processing temperatures necessitate corresponding safety precautions because of the high mercury vapor pressure due to the toxicity of the mercury.

Es ist daher eine Aufgabe der Erfindung, Amalgamkugeln aus Zinnamalgam zur Verfügung zu stellen, die einen hohen Quecksilbergehalt aufweisen und ohne Gefährdung der menschlichen Gesundheit sicher gelagert und bei der Herstellung von Energiesparlampen eingesetzt werden können.It is therefore an object of the invention to provide amalgam balls of Zinnamalgam available, which have a high mercury content and can be safely stored without risk to human health and used in the production of energy-saving lamps.
Diese Aufgabe wird gelöst durch Amalgamkugeln aus einem Zinnamalgam, welches einen Quecksilbergehalt zwischen 30 und 70 Gew.-% aufweist. Bevorzugt weisen die Amalgamkugeln einen Quecksilbergehalt von 30 bis 60 und insbesondere von 40 bis 55 Gew.-% auf.This object is achieved by amalgam balls of a Zinnamalgam, which has a mercury content between 30 and 70 wt .-%. The amalgam spheres preferably have a mercury content of from 30 to 60 and in particular from 40 to 55% by weight.
Die Kugeln können nach einem in der
Für die Zwecke der Erfindung sind Amalgamkugeln mit Durchmessern zwischen 50 und 2000, bevorzugt zwischen 500 und 1500 µm geeignet.For the purposes of the invention amalgam spheres with diameters between 50 and 2000, preferably between 500 and 1500 microns are suitable.
Es hat sich gezeigt, daß auf der Oberfläche der so hergestellten Amalgamkugeln flüssige Phasen auftreten, so daß die Kugeln bei Lagerung und Handhabung miteinander verkleben, wenn keine Maßnahmen dagegen unternommen werden. Das Verkleben kann zum Beispiel verhindert werden, wenn die Amalgamkugeln bei Temperaturen unter 8 °C gelagert und verarbeitet werden. Für die Lagerung wird eine Temperatur von -18 °C bevorzugt.It has been found that liquid phases occur on the surface of the amalgam beads thus produced, so that the balls stick together during storage and handling, if no measures are taken against it. Bonding can be prevented, for example, if the amalgam balls are stored and processed at temperatures below 8 ° C. For storage, a temperature of -18 ° C is preferred.
Die Neigung der Amalgamkugeln zum Verkleben kann unterbunden werden, wenn die Kugeln mit einem Pulver eines Metalls beschichtet werden, welches mit Quecksilber ein Amalgam bildet. Durch die Amalgamierung des Metallpulvers bildet sich auf den Kugeln eine Oberflächenschicht mit einem geringen Quecksilbergehalt aus, die bei den üblichen Verarbeitungstemperaturen der Amalgamkugeln keine flüssigen Phasen mehr enthält und somit die Klebeneigung gegenüber den unbehandelten Kugeln unterbindet.The tendency of the amalgam beads to stick together can be inhibited if the balls are coated with a powder of a metal which forms an amalgam with mercury. Due to the amalgamation of the metal powder, a surface layer with a low mercury content is formed on the spheres, which no longer contains any liquid phases at the usual processing temperatures of the amalgam spheres and thus prevents the adhesion tendency from the untreated spheres.
Das für die Beschichtung eingesetzte Metallpulver sollte keine Teilchen mit einem Korndurchmesser größer als 100 µm enthalten. Teilchen mit größeren Korndurchmessern amalgamieren nur unvollständig und führen zu einer rauhen Oberfläche der Kugeln, die eine Dosierung der Kugeln erschwert. Bevorzugt wird eine Metallpulver verwendet, dessen Pulverteilchen einen Korndurchmesser von kleiner als 80 µm aufweisen. Als geeignete Metalle haben sich Zinn und Zink erwiesen. Zinn ist dabei bevorzugt.The metal powder used for the coating should not contain particles with a grain diameter greater than 100 μm. Particles with larger grain diameters amalgamate only incomplete and lead to a rough surface of the balls, which makes it difficult to meter the balls. Preference is given to using a metal powder whose powder particles have a particle diameter of less than 80 μm. As suitable metals, tin and zinc have been found. Tin is preferred.
Zur Beschichtung der Amalgamkugeln mit dem Metallpulver können die Kugeln zum Beispiel in einem rotierenden Kessel vorgelegt und unter ständigem Umwälzen mit dem Metallpulver bestreut werden, bis kein Verkleben der Kugeln mehr feststellbar ist.For coating the amalgam balls with the metal powder, the balls can be presented, for example, in a rotating vessel and sprinkled with constant circulation with the metal powder until no sticking of the balls is more detectable.
Zur weiteren Erläuterung der Erfindung dient die folgende Tabelle. Sie zeigt berechnete Werte für die Gesamtmasse (Sn+Hg) und die Quecksilbermasse (Hg) von Zinnamalgam-Kugeln in Abhängigkeit vom Durchmesser der Kugeln und für Zinnamalgame mit Quecksilbergehalten zwischen 20 und 50 Gew.-%. In der Tabelle sind außerdem die Dichten ρ der verschiedenen Amalgame angegeben, wie sie für die Berechnungen verwendet wurden.To further explain the invention, the following table is used. It shows calculated values for the total mass (Sn + Hg) and the mercury mass (Hg) of tin amalgam spheres depending on the diameter of the spheres and for tin amalgams with mercury contents between 20 and 50 wt .-%. The table also shows the densities ρ of the different amalgams used in the calculations.
Durch Verwendung von Zinnamalgam mit hohen Quecksilbergehalten kann mit Kugeln gleichen Durchmessers deutlich mehr Quecksilber in die Gasentladungskolben eingebracht werden als mit einem Zinnamalgam mit geringem Quecksilbergehalt von nur 20 Gew.-%. So enthalten Amalgamkugeln aus einem SnHg50 mit 50 Gew.-% Quecksilber etwa die dreifache Masse an Quecksilber wie Amalgamkugeln aus SnHg20 mit nur 20 Gew.-% Quecksilber.
