Description

Die Erfindung betrifft einen atmungsaktiven Handschuh als Überziehhandschuh, über einen schnitt- und stichfesten und fusselfreien Unterziehhandschuh, zum Verpacken und Sortieren von hochreinem Silicium, wie Polysiliciumbruch und Silicium-Wafern.The invention relates to a breathable glove as a pull-on glove, via a cut and puncture-resistant and lint-free under glove, for packaging and sorting high-purity silicon, such as polysilicon and silicon wafers.

Um eine Kontamination von hochreinem Silicium beim Verpacken und beim Sortieren per Hand zu vermeiden, müssen grundsätzlich Handschuhe getragen werden. Damit auch eine durch den Handschuh hervorgerufene Kontamination ausgeschlossen werden kann, dürfen die Handschuhe beim Berühren der Siliciumoberfläche möglichst wenig Partikel abgeben. Verschiedene Messungen von Herstellern, wie beispielsweise der Firma KNF Clean Room Corp. und Icarus West Inc. haben gezeigt dass Handschuhe aus höchstreinem Polyethylen (PE) die besten Werte bezüglich der Partikelabgabe pro Fläche hierfür ergeben. Sie sind damit anderen Materialien wie beispielsweise Nylon, Polyester, PVC, Latex, Polyurethan oder Handschuhen aus Nitrilen weit überlegen.In order to avoid contamination of high-purity silicon during packaging and sorting by hand, gloves must always be worn. So that a contamination caused by the glove can be excluded, the gloves may emit as few particles as possible when touching the silicon surface. Various measurements from manufacturers such as KNF Clean Room Corp. and Icarus West Inc. have shown that gloves made from ultra-high purity polyethylene (PE) give the best particle emission per area values. They are therefore far superior to other materials such as nylon, polyester, PVC, latex, polyurethane or nitrile gloves.

Handschuhe aus höchstreinem PE, bevorzugt LDPE, haben aber leider den Nachteil, dass sie nicht atmungsaktiv sind und die Hände dadurch bereits nach wenigen Minuten zu schwitzen beginnen. Auch besitzen Handschuhe aus PE keinerlei Schnittfestigkeit. Deshalb muss aus Sicherheitsgründen beim Anfassen von den extrem scharfen Siliciumbruchstücken unter den Handschuhen aus PE ein weiterer schnittfester Handschuh getragen werden.Unfortunately, gloves made of ultra-pure PE, preferably LDPE, have the disadvantage that they are not breathable and that their hands begin to sweat after just a few minutes. Also, gloves made of PE have no cut resistance. Therefore, for safety reasons, when handling the extremely sharp silicon fragments under the gloves made of PE, another cut-resistant glove must be worn.

Erfahrungen haben gezeigt, dass bereits nach dem Anfassen von wenigen Kilogramm an Siliciumbruchstücken der PE-Handschuh einreißt und deshalb ausgetauscht werden muss. Auf Grund des durch den Überhandschuh aus PE verursachten, sehr starken Schwitzens der Hände muss der schnittfeste Unterhandschuh ebenfalls nach etwa 30 Minuten gewechselt werden.Experience has shown that even after touching a few kilograms of silicon fragments of the PE glove ruptures and therefore must be replaced. Due to the very heavy sweating of the hands caused by the overglove made of PE, the cut-resistant underglove must also be changed after about 30 minutes.

Beim Arbeiten sind die Mitarbeiter deshalb angehalten, jede Minute die PE-Handschuhe auf Beschädigungen zu überprüfen. Wird eine Beschädigung übersehen, so besteht das Risiko, dass natriumchlorid-haltiger, menschlicher Schweiß auf das hochreine Silicium gelangt und dieses damit unbrauchbar macht. Messungen im laufenden Betrieb zeigen immer wieder Natriumspuren an den Siliciumbruchstücken, das auf Schwitzen der Verpacker und/oder Sortierer zurückzuführen ist.When working, therefore, the employees are required to check every minute the PE gloves for damage. If damage is overlooked, there is a risk that sodium chloride-containing, human sweat on the high-purity silicon and makes it useless. Measurements during operation show again and again sodium traces on the silicon fragments, which is due to sweating of the packers and / or sorters.

Ein weiterer Nachteil bei der Verwendung von Handschuhen aus PE besteht darin, dass es durch das Schwitzen unter dem Handschuh bei einer Langzeitanwendung zu dauerhaften, nicht reversiblen Hautirritationen kommen kann.Another disadvantage of using PE gloves is that perspiration under the glove may result in long term, non-reversible skin irritation in long term use.

Aus dem Stand der Technik sind verschiedene Lösungen für atmungsaktive oder schnittfeste Handschuhe bekannt. So beschreibt beispielsweise DE-102005044839 einen atmungsaktiven Handschuh mit einer Handinnenfläche aus Silicon zum besseren Greifen und einem Handrücken aus einem luftdurchlässigen Gewebe. US2007028356 beschreibt einen mehrlagigen und atmungsaktiven Handschuh dessen innere Lage atmungsaktiv ist und dessen äußere Lage einen hohen Reibungskoeffizienten aufweist um damit möglichst sicher greifen zu können. Kein aus dem Stand der Technik bekannter Handschuh zielt jedoch auf eine gute Atmungsaktivität kombiniert mit einer minimalen Partikelabgabe der Handschuhinnenfläche auf das zu greifende Stück.Various solutions for breathable or cut-resistant gloves are known from the prior art. For example, describes DE-102005044839 A breathable glove with a palm made of silicone for better grip and a back of the hand from an air-permeable fabric. US2007028356 describes a multi-layered and breathable glove whose inner layer is breathable and whose outer layer has a high coefficient of friction in order to grip as safely as possible. However, no glove known from the prior art aims for good breathability combined with minimal particle delivery of the glove inner surface to the piece to be gripped.

Es bestand nun die Aufgabe einen Handschuh zum Verpacken und Sortieren von hochreinem Silicium bereitzustellen, der zum einen beste Werte bezüglich der Partikelabgabe PE pro Fläche aufweist und gleichzeitig atmungsaktiv ist.The object was therefore to provide a glove for packaging and sorting high-purity silicon, which, on the one hand, has the best values of particle output per surface area and at the same time is breathable.

Überraschenderweise wurde nun gefunden, dass man durch das Zusammenfügen einer Handinnenfläche aus PE und eines Handrücken aus einem atmungsaktiven, reinraumgerechten Textilstoff einen Handschuh zum Verpacken und Sortieren von hochreinem Silicium herstellen kann, der die Nachteile aus dem Stand der Technik nicht besitzt.Surprisingly, it has now been found that by combining a palm of PE and a back of the hand from a breathable, cleanroom-compatible fabric a glove for packaging and sorting of high-purity silicon can manufacture, which does not possess the disadvantages of the prior art.

Gegenstand der Erfindung ist ein Handschuh zur Verwendung beim Verpacken und Sortieren von hochreinen Silicium, dadurch gekennzeichnet, dass die Handinnenfläche des Handschuhs aus Polyethylen besteht und die Handrückenfläche des Handschuhs aus einem atmungsaktiven, reinraumgerechten Textilstoff, wobei beide Flächen dauerhaft miteinander verbunden sind.The invention relates to a glove for use in packaging and sorting of high-purity silicon, characterized in that the palm of the glove is made of polyethylene and the back of the glove of the hand made of a breathable, clean room textile, both surfaces are permanently connected.

Bei dem erfindungsgemäßen Handschuh wird die Handinnenfläche aus höchstreinem PE, bevorzugt LDPE, hergestellt und die Oberseite des Handschuhs atmungsaktiv gestaltet. Ansätze dies durch eine Perforierung mit Löchern auf der Oberseite des PE-Handschuhs zu erreichen sind erfolglos, da der PE-Handschuh dadurch instabil wird und bereits innerhalb kürzester Zeit beim Anfassen der Siliciumstücke zerreißen kann.In the case of the glove according to the invention, the palm of the hand is made from ultrapure PE, preferably LDPE, and the upper side of the glove is made breathable. Approaches to achieve this by perforating with holes on the top of the PE glove are unsuccessful because the PE glove is unstable and can already tear within a very short time when touching the silicon pieces.

Als Material für den Handrücken können verschiedene atmungsaktive und reinraumgerechte Textilstoffe verwendet werden. Bevorzugt wird dabei Tyvek® der Firma DuPont, ein papiervliesartiges Faserfunktionstextil aus thermisch verschweißten Fasern aus Polyethylen mit hoher Dichte (HDPE).As material for the back of the hand, various breathable and cleanroom-compatible fabrics can be used. Thereby Tyvek ® from DuPont, a paper-like nonwoven fiber textile function of thermally welded fibers of high density polyethylene (HDPE) is preferred.

Tyvek® verhält sich von seiner Verformbarkeit her etwa wie Papier, ist dabei aber strapazierfähiger. Als Material für Schutzkleidung ist es deshalb geeignet, weil Tyvek® einerseits selbst nur sehr wenige Fasern verliert, andererseits durch das Vlies nahezu keine vom Körper abgeschiedenen Zellen durch das Material heraustreten können. So können sterile Arbeitsbedingungen, wie sie in oben genannten Arbeitsbereichen benötigt werden, aufrechterhalten werden. Aufgrund der Dampfdiffusionsoffenheit, bei gleichzeitiger Wasserdichtigkeit des Materials, kann gasförmiger Schweiß leicht durch die Faser nach außen treten.Tyvek ® is about as deformable as paper, but is more durable. As a material for protective clothing, it is therefore suitable because Tyvek ® on the one hand loses only a very few fibers, on the other hand can pass through the fabric almost no secreted by the body cells through the material. Thus, sterile working conditions as required in the above-mentioned work areas can be maintained. Due to the vapor permeability, with simultaneous waterproofness of the material, gaseous sweat can easily pass through the fiber to the outside.

Tyvek® kann mit einer höchstreinen PE-Folie so gut verschweißt werden, dass ein Handschuh erhalten wird, der die gleiche Stabilität beim Anfassen der Polysiliciumstücke besitzt wie der reine PE-Handschuh. Die Schweißnaht zwischen dem Textilwerkstoff auf der Oberseite (Handrücken) und dem hochreinen LD-PE auf der Innenfläche des Handschuhes besitzt dabei die gleiche Schweißnahtfestigkeit wie die Schweißnaht zwischen zwei PE-Folien bei einem Handschuh mit Innen- und Oberseite aus PE.Tyvek ® can be welded with a high-purity PE film so well that a glove is obtained which is the same Stability when touching the Polysiliciumstücke possesses like the pure PE glove. The weld seam between the textile material on the upper side (back of the hand) and the high-purity LD-PE on the inner surface of the glove has the same weld seam strength as the weld seam between two PE films in a glove with PE inner and top.

Die Schweißnahtfestigkeit wurde dabei nach DIN55543/T.3 überprüft. Die mittlere Schweißnahtfestigkeit beim PE-Handschuh zwischen LDPE-Folie an der Ober- und Unterseite betrug ebenso wie bei dem erfindungsgemäßen Handschuh zwischen Oberseite aus Tyvek® und Unterseite aus LDPE 50 N/15 mm.The weld seam strength was checked according to DIN55543 / T.3. The average weld strength in the PE glove between LDPE film on the top and bottom was as well as the glove according to the invention between top of Tyvek ® and bottom of LDPE 50 N / 15 mm.

Als Unterziehhandschuh muss aus Sicherheitsgründen auch beim erfindungsgemäßen Handschuh ein schnitt- und stichfester Unterhandschuh getragen werden. Stand der Technik für geeignete Unterziehhandschuhe ist eine Kombination aus drei verschiedenen Handschuhtypen. Als erster Handschuh wird zum Aufsaugen des Schweißes ein reiner Baumwollhandschuh getragen. Über den Baumwollhandschuh wird ein schnittfester Handschuh, bevorzugt aus einer Aramidfaser, besonders bevorzugt dem Material Kevlar® (DuPont), gezogen. Da Kevlar® leider fusselt, muss nochmals ein fusselfreier Handschuh, bevorzugt ein Vinylhandschuh, darüber gezogen werden. Erst dann kommt der PE-Handschuh zum Einsatz.As underwear glove must be worn for safety reasons in the glove according to the invention a cut and puncture resistant glove. The state of the art for suitable undergloves is a combination of three different glove types. As the first glove a pure cotton glove is worn to absorb the sweat. About the cotton glove a cut-resistant glove, preferably made of an aramid fiber, particularly preferably the material Kevlar ® (DuPont) pulled. As Kevlar ® unfortunately lags, a lint-free glove, preferably a vinyl glove, must be pulled over it again. Only then will the PE glove be used.

Das Tragen von vier verschiedenen Handschuhen übereinander hat jedoch mehrere Nachteile. Zum einen benötigt man zum fachgerechten Anziehen dieser Schutzhandschuhe mehrere Minuten und aufgrund der vielen Lagen wird die Fingerfertigkeit deutlich beeinträchtigt. Ein weiterer Nachteil sind die hohen Kosten für vier Handschuhe für beide Hände, die regelmäßig ausgetauscht werden müssen.However, wearing four different gloves over each other has several disadvantages. On the one hand, it takes several minutes to professionally put on these protective gloves and due to the many layers, the dexterity is significantly impaired. Another disadvantage is the high cost of four gloves for both hands, which must be replaced regularly.

Überraschenderweise konnte durch die Verwendung eines Unterziehhandschuhs aus einer hochfesten Polyethylen-Faser mit einer sehr hohen Zugfestigkeit, die zusätzlich mit Polyurethan (PU) beschichtet ist, bei der Verwendung des erfindungsgemäßen PE-Kevlar® Handschuhs, die Zahl der Unterziehhandschuhe von drei auf einen Handschuh verringert werden, ohne die Schutzwirkung zu verringern und die Schweißbildung zu erhöhen.Surprisingly, by using an undercloth made of a high-strength polyethylene fiber with a very high tensile strength, which is additionally coated with polyurethane (PU), when using the inventive PE- Kevlar® glove, the number of under gloves from three to one glove are reduced without reducing the protective effect and increasing perspiration.

Ein weiterer Gegenstand der Erfindung ist ein mehrlagiger Handschuh zur Verwendung beim Verpacken und Sortieren von hochreinen Silicium, dadurch gekennzeichnet, dass die äußere Lage des Handschuhs aus einer Handinnenfläche aus Polyethylen besteht und die Handrückenfläche des Handschuhs aus einem atmungsaktiven, reinraumgerechten Textilstoff, wobei beide Flächen dauerhaft miteinander verbunden sind, und mindestens eine der innen liegenden Lagen des Handschuhs aus einer hochfesten Polyethylen Faser mit einer sehr hohen Zugfestigkeit besteht, die mit Polyurethan beschichtet ist.Another object of the invention is a multi-layer glove for use in packaging and sorting of high purity silicon, characterized in that the outer layer of the glove consists of a palm of polyethylene and the back of the glove of the hand made of a breathable, cleanroom textile, both surfaces permanently and at least one of the inner layers of the glove consists of a high strength polyethylene fiber having a very high tensile strength coated with polyurethane.

Bevorzugt wird als hochfeste Polyethylen-Faser Dyneema® (DSM) eingesetzt, die zusätzlich mit PU beschichtet ist (PU-Dyneema®). Besonders bevorzugt wird die PU-Beschichtung eines nahtlosen Dyneema®-Trägergewebes.As high-strength polyethylene fiber Dyneema ® (DSM) is preferably used, which is additionally coated with polyurethane (PU-Dyneema ®). The PU coating of a seamless Dyneema ® -Trägergewebes is particularly preferred.

Die beiden erfindungsgemäßen Lagen des Handschuhs können sowohl als Einzelhandschuhe, separat übereinander getragen werden, oder auch fest miteinander verbunden sein. Zusätzlich zu den beiden erfindungsgemäßen Lagen kann der Handschuh je nach Bedarf noch weitere Innenlagen über- und/oder unterhalb der hochfesten Lage aus Polyethylenfasern besitzen.The two layers of the glove according to the invention can be worn both separately as single gloves, one above the other, or else firmly connected to one another. In addition to the two layers according to the invention, the glove can, if required, also have additional inner layers above and / or below the high-strength layer of polyethylene fibers.

Die Verwendung des Materials PU-Dyneema® als Innen- oder Unterziehhandschuh vereinigt Schnittfestigkeit und Stichfestigkeit mit Atmungsaktivität bei gleichzeitig geringer Neigung zur Fusselabgabe. Aufgrund der dünnen Fasern ist die Fingerfertigkeit ebenfalls sehr gut. Dadurch ergibt sich gegenüber dem Stand der Technik mit der Verwendung von vier verschiedenen Handschuhen eine erhebliche Produktivitätssteigerung. Das Wechseln der Handschuhe kann in wenigen Sekunden erfolgen und die Beschaffungskosten können gesenkt werden.The use of the material PU-Dyneema ® as inner or under glove combines cut resistance and puncture resistance with breathability and at the same time a low tendency to lint. Due to the thin fibers, the dexterity is also very good. This results in a significant increase in productivity over the prior art with the use of four different gloves. Changing the gloves can be done in seconds and the procurement costs can be reduced.

Sowohl für das Material PU-Dyneema® als auch für Tyvek® können alle industrieüblichen Faser- und Fliesstärken für die Handschuhe eingesetzt werden. Die Materialstärken können dabei beispielsweise auf die spezielle Anwendung oder auch die Größe der Handschuhe abgestimmt werden.For the material PU-Dyneema ® as well as for Tyvek ® all industry-standard fiber and fleece thicknesses for the gloves can be used. The material thicknesses can be adjusted for example to the specific application or the size of the gloves.

Anhand der folgenden Beispiele soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to the following examples.

Beispiel 1:Example 1:

In einem Langzeitversuch wurden 100 Tonnen Polysiliciumbruch der Größe 5 (mittleres Gewicht von ca. 600 g, mit einer mittleren Kantenlänge von 120 mm) per Hand einzeln in PE-Beutel verpackt. Als Handschuhe wurden die erfindungsgemäßen PE-Tyvek® Handschuhe in Kombination mit einem Unterhandschuh bestehend aus PU-Dyneema® verwendet. Der Verbrauch an PE-Tyvek® Handschuhen betrug 4466 Paar und der Verbrauch an PU-Dyneema® Unterhandschuhen betrug 208 Paar.In a long-term test, 100 tons of polysilicon fragments of size 5 (average weight of approx. 600 g, with an average edge length of 120 mm) were packed individually in PE bags by hand. As gloves the PE-Tyvek ® gloves according to the invention in combination with a glove consisting of PU-Dyneema ® were used. The consumption of PE Tyvek ® gloves was 4466 couple and the consumption of PU Dyneema ® glove liners was 208 pair.

Vergleichsbeispiel 1:Comparative Example 1

Analog zu Beispiel 1 wurden in einem weiteren Langzeitversuch ebenfalls 100 Tonnen Polysiliciumbruch der Größe 5 (mittleres Gewicht von ca. 600 g, mit einer mittleren Kantenlänge von 120 mm) per Hand einzeln in PE-Beutel verpackt. Als Handschuhe wurden aber reine PE-Handschuhe in Kombination mit einem Unterhandschuh bestehend aus PU-Dyneema® verwendet. Der Verbrauch an PE-Handschuhen betrug 5067 Paar und der Verbrauch an PU-Dyneema® Unterhandschuhen betrug 1123 Paar.Analogous to Example 1, in a further long-term experiment, 100 tons of polysilicon fragments of size 5 (average weight of approx. 600 g, with an average edge length of 120 mm) were individually packed by hand in PE bags. As gloves but pure PE gloves were used in combination with a glove consisting of PU-Dyneema ® . The consumption of PE gloves was 5067 pairs and the consumption of PU-Dyneema ® under gloves was 1123 pairs.

Das Vergleichsbeispiel zeigt, dass durch die Verwendung der erfindungsgemäßen, atmungsaktiven Handschuhe aus PE-Tyvek® der Verbrauch an schnitt- und stichfesten Unterziehhandschuhen aus PU-Dyneema® um ca. 80 % reduziert werden konnte.The comparative example shows that could be reduced by the use of the invention, breathable gloves made of PE-Tyvek ®, the consumption of under-cut and puncture resistant gloves made of PU Dyneema ® by about 80%.

Beispiel 2:Example 2:

In einem Reinraum der Klasse 100 wurden 15 sauer geätzte Polysiliciumbruchstücke mit einem Gewicht von 100 g pro Stück mit einem erfindungsgemäßen Handschuh, bestehend aus PE-Tyvek® für 30 Sekunden angefasst. Als Unterziehhandschuh wurde ein PU-Dyneema® getragen. Die Polybruchstücke wurden anschließend bezüglich des Metalloberflächengehalts untersucht. Die Ergebnisse sind in Tabelle 1 dem Vergleichsbeispiel 2 gegenübergestellt.In a clean room of class 100, 15 acid etched Polysiliciumbruchstücke with a weight of 100 g per piece with a glove according to the invention, consisting of PE-Tyvek ® touched for 30 seconds.
