Definitions
- the invention relates to a breathing apparatus with a protective cover, in particular a smoke protection hood, the breathing connection of which is connected to a chemical absorbing the water vapor and the CO2 and oxygen-releasing chemical or to a filter, and whose cover or.
- Hood material consists of a coated composite material with a carrier fabric made of tear-resistant, heat-resistant and water-vapor-repellent fibers.
- Such respiratory protective devices with, for example, a smoke protection hood as a protective cover are used for use in non-breathable atmospheres and are also intended to protect the wearer from harmful heat effects.
- the breathing apparatus itself is attached at a suitable location, for example in front of the chest or in the neck area of the device wearer, and has a flow connection into the interior of the hood space. When the respirator is put on and the hood is pulled over, the oxygen-releasing chemical reacts and releases its oxygen.
- the hood material itself consists of a fabric made of tear-resistant, heat-resistant and water vapor-repellent material, such as Glass fibers are. This is coated with polytetrafluoroethylene (PTFE).
- PTFE polytetrafluoroethylene
- a disadvantage of known hood materials is that the brittle glass fibers break too easily and the broken fibers do not withstand subsequent tearing, so that undesirable leaks or even holes occur which destroy effective respiratory protection.
- such a hood fabric is not strong enough to penetrate pointed objects.
- the processing of the known hood material is complex, since special precautions must be taken for the strength of the resulting seams on the hood cut; an adhesive bond is not resistant to PTFE due to its low adhesion and seams often tear due to the brittleness of the fabric.
- Respirators with a chemical as an oxygen source which absorbs carbon dioxide and water vapor and uses it to form oxygen (e.g. KO2) are sensitive to moisture, so that such respirators must be packaged in a water vapor-tight and dry manner so that during the storage period of the respirator in the packaging diffuses or from the components not released water vapor leads to premature activation of the chemical and unwanted release of oxygen.
- Sealed packaging is expensive, however, and drying the various components that are in fluid communication with the chemical requires an additional drying operation. If extensive casing material, such as a hood, is also packaged, the water vapor stored by the casing material can still be released into the interior and to the chemical despite the packaging being water-tight. To prevent this, the chemical cartridge would also have to be sealed.
- Such devices are described in DE-AS 11 95 602.
- the present invention is therefore based on the object to improve a respirator of the type mentioned so that the material which is in flow communication with the chemical has both the lowest possible water vapor storage or release, and the protective cover breaks despite its elasticity and is tearproof and easy to work with.
- the composite material has the carrier fabric made of glass fibers, which is provided on one side with a PVC coating to the environment and has a silicone coating on its surface facing away from the PVC coating.
- the silicone-coated glass fiber fabric is characterized by a lack of water vapor absorption and storage, which prevents later undesired water vapor emission from the outset.
- the outer PVC coating which is directed towards the surroundings, ensures a largely gas-tight seal to the outside and facilitates the processability of the fabric material into a protective cover, in particular a protective hood.
- a more extensive processing of the fabric material into a complete protective suit, which encloses the entire body of the device wearer, is also easier to achieve with the features according to the invention.
- the entire casing material can be included in the packaging of a respirator without any special additional drying process, although there is no need to fear that an excessive release of water vapor could lead to an early development of oxygen from the chemical.
- a composite material can be produced in a simple manner in such a way that both the PVC coating and the silicone coating are applied as an impregnation to the glass fiber fabric.
- silane acts as an adhesion promoter, ensures that the coatings last longer.
- the piece of fabric shown in Fig. 1 is designed in three layers, the middle layer is a glass fiber fabric (1), the individual glass fibers (2) are shown in their end face.
- the surface facing the outside during the subsequent processing of the composite material is provided with a PVC coating (3).
- the surface of the glass fiber fabric (1) opposite the coating (3) is covered with a silicone coating (4).
- the individual glass fibers (2) can be provided with a sheathing (5) made of silane as an adhesion promoter (Fig. 2) and linked together to form a fabric (1) made of coated glass fibers (25).
- a shell (6) is shown, both the head area and the shoulder and back or. Breast area of a person not shown covered.
- a screen (7) is provided in the head area of the casing (6), below which a half mask (8) with a connecting tube (9) is connected to a breathing apparatus (10).
- the breathing apparatus has a chemical cartridge, not shown, with a chemical that absorbs the water vapor and the CO2 of the exhaled gas, as well as an oxygen-releasing chemical.
Abstract
Description
Die Erfindung betrifft ein Atemschutzgerät mit einer Schutzhülle, insbesondere einer Rauchshutzhaube, dessen Atemanschluß mit einem den Wasserdampf und das CO₂ aufnehmenden sowie sauerstoffabgebenden Chemikal oder mit einem Filter verbunden ist und dessen Hüllen-bzw. Haubenmaterial aus einem beschichteten Verbundwerkstoff mit einem Trägergewebe aus reißfesten, hitzebeständigen und wasserdampfabweisenden Fasern besteht.The invention relates to a breathing apparatus with a protective cover, in particular a smoke protection hood, the breathing connection of which is connected to a chemical absorbing the water vapor and the CO₂ and oxygen-releasing chemical or to a filter, and whose cover or. Hood material consists of a coated composite material with a carrier fabric made of tear-resistant, heat-resistant and water-vapor-repellent fibers.
Derartige Atemschutzgeräte mit beispielsweise einer Rauchschutzhaube als Schutzhülle werden zur Verwendung in nicht atembaren Atmosphären eingesetzt und sollen auch dazu dienen, den Träger vor schädlichen Hitzeeinwirkungen zu schützen. Das Atemschutzgerät selbst ist an geeigneter Stelle, beispielsweise vor der Brust oder im Nackenbereich des Geräteträgers angebracht, und besitzt eine Strömungsverbindung in das Innere des Haubenraumes. Beim Anlegen des Atemschutzgerätes und nach Überziehen der Haube reagiert die sauerstoffabgebende Chemikalie und gibt ihren Sauerstoff ab.Such respiratory protective devices with, for example, a smoke protection hood as a protective cover are used for use in non-breathable atmospheres and are also intended to protect the wearer from harmful heat effects. The breathing apparatus itself is attached at a suitable location, for example in front of the chest or in the neck area of the device wearer, and has a flow connection into the interior of the hood space. When the respirator is put on and the hood is pulled over, the oxygen-releasing chemical reacts and releases its oxygen.
Das Haubenmaterial selbst besteht aus einem Gewebe aus reißfestem, hitzebeständigem und wasserdampfabweisendem Material, wie es z.B. Glasfasern sind. Dieses ist mit Polytetrafluorethylen (PTFE) beschichtet. Das Haubenmaterial ist somit feuerbeständig, leicht und anschmiegsam, so daß die Haube den Geräteträger möglichst wenig in seiner Bewegungsfreiheit behindert. Ein derartiges Atemschutzgerät ist in dem Firmenprospekt AVIA 5287 4/77 der Firma Scott Aviation, Lancaster, N.Y.14086, USA, beschrieben.The hood material itself consists of a fabric made of tear-resistant, heat-resistant and water vapor-repellent material, such as Glass fibers are. This is coated with polytetrafluoroethylene (PTFE). The hood material is thus fire-resistant, light and conformable, so that the hood hinders the equipment wearer as little as possible in his freedom of movement. Such a breathing apparatus is described in the company brochure AVIA 5287 4/77 from Scott Aviation, Lancaster, NY14086, USA.
Nachteilig bei bekannten Haubenstoffen ist, daß die spröden Glasfasern zu leicht brechen und die gebrochenen Fasern einer nachfolgenden Reißbeanspruchung nicht standhalten, so daß unerwünscht Undichtheiten oder gar Löcher entstehen, die einen wirkungsvollen Atemschutz zunichte machen. Außerdem ist ein derartiger Haubenstoff nicht gegen Durchdringung spitzer Gegenstände fest genug. Die Verarbeitung des bekannten Haubenmaterials ist aufwendig, da besondere Vorkehrungen für die Festigkeit der entstehenden Nahtstellen am Haubenzuschnitt vorgesehen werden müssen; eine Klebung ist wegen der geringen Haftfähigkeit auf PTFE nicht beständig und Nähte reißen wegen der Sprödigkeit des Gewebes häufig ein.A disadvantage of known hood materials is that the brittle glass fibers break too easily and the broken fibers do not withstand subsequent tearing, so that undesirable leaks or even holes occur which destroy effective respiratory protection. In addition, such a hood fabric is not strong enough to penetrate pointed objects. The processing of the known hood material is complex, since special precautions must be taken for the strength of the resulting seams on the hood cut; an adhesive bond is not resistant to PTFE due to its low adhesion and seams often tear due to the brittleness of the fabric.
Atemschutzgeräte mit einem Chemikal als Sauerstoffquelle, welches Kohlensäure und Wasserdampf aufnimmt und zur Bildung des Sauerstoffs einsetzt (z.B. KO₂) sind feuchteempfindlich, so daß derartige Atemschutzgeräte wasserdampfdicht und trocken verpackt werden müssen, damit während der Lagerzeit des Atemschutzgerätes in die Verpackung diffundierender oder von den Bauteilen freiwerdender Wasserdampf nicht zu einem vorzeitigen Aktivieren der Chemikalie und unerwünschter Freigabe von Sauerstoff führt. Eine versiegelte Verpackung ist jedoch aufwendig, und die Trocknung der verschiedenen Bauteile, die mit der Chemikalie in Strömungsverbindung stehen, erfordert einen zusätzlichen Trocknungsarbeitsgang. Wird umfangreiches Hüllenmaterial, wie z.B. eine Kopfhaube, mitverpackt, kann trotz nach außen hin wasserdampfdichter Verpackung dennoch der vom Hüllenmaterial gespeicherte Wasserdampf in das Innere und an das Chemikal abgegeben werden. Um dies zu verhindern, müßte auch noch die Chemikalpatrone versiegelt werden. Derartige Geräte sind in der DE-AS 11 95 602 beschrieben.Respirators with a chemical as an oxygen source, which absorbs carbon dioxide and water vapor and uses it to form oxygen (e.g. KO₂) are sensitive to moisture, so that such respirators must be packaged in a water vapor-tight and dry manner so that during the storage period of the respirator in the packaging diffuses or from the components not released water vapor leads to premature activation of the chemical and unwanted release of oxygen. Sealed packaging is expensive, however, and drying the various components that are in fluid communication with the chemical requires an additional drying operation. If extensive casing material, such as a hood, is also packaged, the water vapor stored by the casing material can still be released into the interior and to the chemical despite the packaging being water-tight. To prevent this, the chemical cartridge would also have to be sealed. Such devices are described in DE-AS 11 95 602.
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, ein Atemschutzgerät der genannten Art so zu verbessern, daß das Material, welches mit dem Chemikal in Strömungsverbindung steht, sowohl eine geringstmögliche Wasserdampfspeicherung bzw. -abgabe aufweist, und die Schutzhülle dabei trotz ihrer Elastizität bruch- und reißfest ist und sich leicht verarbeiten läßt.The present invention is therefore based on the object to improve a respirator of the type mentioned so that the material which is in flow communication with the chemical has both the lowest possible water vapor storage or release, and the protective cover breaks despite its elasticity and is tearproof and easy to work with.
Die Lösung der Aufgabe erfolgt dadurch, daß der Verbundwerkstoff das Trägergewebe aus Glasfasern besitzt, welches einseitig zur Umgebung hin mit einer PVC-Beschichtung versehen ist und auf seiner der PVC-Beschichtung abgewandten Fläche eine Silikon-Beschichtung aufweist.The object is achieved in that the composite material has the carrier fabric made of glass fibers, which is provided on one side with a PVC coating to the environment and has a silicone coating on its surface facing away from the PVC coating.
Der Vorteil der Erfindung liegt im wesentlichen darin, daß das an sich spröde Glasfasergewebe durch die Silikonbeschichtung geschmeidig wird und auch einerThe advantage of the invention lies essentially in the fact that the brittle glass fiber fabric itself becomes supple due to the silicone coating and also one
Knickbelastung standhält, welche nicht zum Einreißen des Gewebes führt. Das silikonbeschichtete Glasfasergewebe zeichnet sich durch fehlende Wasserdampfabsorption und -speicherung aus, wodurch eine spätere unerwünschte Wasserdampfabgabe von vornherein unterbunden wird. Die äußere, zur Umgebung hin gerichtete PVC-Beschichtung sorgt für einen weitestgehend gasundurchlässigen Abschluß nach außen hin und erleichtert die Verarbeitbarkeit des Gewebematerials zu einer Schutzhülle, insbesondere zu einer Schutzhaube. Eine umfassendere Verarbeitung des Gewebestoffes zu einem vollständigen Schutzanzug, welcher den ganzen Körper des Gerätesträgers umschließt, ist mit den erfindungsgemäßen Merkmalen ebenfalls leichter verwirklichbar.Withstands kink loads that do not lead to tearing of the tissue. The silicone-coated glass fiber fabric is characterized by a lack of water vapor absorption and storage, which prevents later undesired water vapor emission from the outset. The outer PVC coating, which is directed towards the surroundings, ensures a largely gas-tight seal to the outside and facilitates the processability of the fabric material into a protective cover, in particular a protective hood. A more extensive processing of the fabric material into a complete protective suit, which encloses the entire body of the device wearer, is also easier to achieve with the features according to the invention.
Durch den fehlenden Wasserdampfgehalt und die geringe Wasserdampfaufnahme des beschichteten Gewebes ist eine Versiegelung des das Chemikal enthaltenden Atemschutzgerätes zu den atemgasführenden Leitungen hin überflüssig, so daß eine Ingebrauchnahme des Gerätes ohne zeitraubendes Aufbrechen einer Versiegelung erfolgen kann. Darüber hinaus kann das gesamte Hüllenmaterial ohne besonderen zusätzlichen Trocknungsvorgang in die Verpackung eines Atemschutzgerätes aufgenommen werden, wobei nicht befürchtet zu werden braucht, daß eine übermäßige Wasserdampfabgabe zu einer frühzeitigen Sauerstoffentwicklung aus dem Chemikal führen könnte.Due to the lack of water vapor content and the low water vapor absorption of the coated fabric, sealing of the respiratory protective device containing the chemical to the breathing gas-carrying lines is superfluous, so that the device can be put into operation without time-consuming breaking of a seal. In addition, the entire casing material can be included in the packaging of a respirator without any special additional drying process, although there is no need to fear that an excessive release of water vapor could lead to an early development of oxygen from the chemical.
Ein Verbundwerkstoff läßt sich auf einfache Weise derart herstellen, daß sowohl die PVC-Beschichtung als auch die Silikon-Beschichtung als eine Imprägnierung auf das Glasfasergewebe aufgetragen ist.A composite material can be produced in a simple manner in such a way that both the PVC coating and the silicone coating are applied as an impregnation to the glass fiber fabric.
Man erhält eine besser haftende Beschichtung, wenn mit Silan ummantelte Glasfasern verwebt werden. Das als Haftvermittler wirkende Silan sorgt für eine dauerhaftere Beständigkeit der Beschichtungen.A better adherent coating is obtained if glass fibers coated with silane are woven. The silane, which acts as an adhesion promoter, ensures that the coatings last longer.
Um die Wasserdampfabgabe aus dem gesamten atemgasführenden Teil noch weiter zu verringern, ist es zweckmäßig, ebenfalls alle diejenigen Bauteile, welche mit dem Chemikal in Strömungsverbindung stehen, wie z.B. der Atembeutel oder Anschlußleitungen, aus dem mit den Beschichtungen versehenen Gewebe entweder anzufertigen oder auszukleiden.In order to further reduce the water vapor release from the entire breathing gas-carrying part, it is also expedient to also all those components which are in flow connection with the chemical, such as, for example, the breathing bag or connecting lines, either to be made or lined from the fabric provided with the coatings.
