Description

In der Vergangenheit waren Reinraumanzüge in erster Linie dazu bestimmt, Partikelemissionen, wie z. B. Hautschuppen oder Faserbruchstücke, von Per­ sonen in Reinräumen zu vermeiden. Heute sind die Anforderungen weit grö­ ßer. Seitdem gasförmige Körperemissionen, wie z. B. NH3 ins Visier genom­ men wurden und deren Schädlichkeit erkannt wurde, versucht man auch gas­ förmige Körperemissionen zu verhindern. Und so entstand der Reinrauman­ zug mit adsorbierenden Eigenschaften.
Die DE 196 34 114.0 beschreibt einen solchen Anzug, bei dem an der Innen­ seite des Stoffes, mit Hilfe einer punktförmig aufgetragenen Haftmasse, Ad­ sorbentien, insbesondere Aktivkohlekügelchen aufgebracht sind. Um insbe­ sondere die NH3-Emission zu unterbinden, ist die Aktivkohle gerne mit einer Säure imprägniert. Die Phosphorsäureimprägnierung wird aber beim Waschen ausgewaschen und ein Nachimprägnieren mit Phosphorsaure, in einer wenn auch spezialisierten Wäscherei, ist nicht unproblematisch. Da zudem Phos­ phorsäure als Umweltbelastung angesehen werden muß, wurde auf andere Imprägnierungen, wie Zitronensäure zurückgegriffen.
Es wurde nun überraschender Weise gefunden, daß wäßrige Zitronensäure auch ohne Adsorbentien die NH3-Emission unterbindet. Anscheinend bietet die große Oberfläche der Mikrofasern eine ausreichende Kontaktfläche, um NH3 vollständig zu absorbieren. Vorteilhaft ist auch, daß das Nachimprägnie­ ren nach dem Waschen problemlos durchführbar ist.
Es ist naheliegend, daß die Zitronensäure nur NH3 bzw. flüchtige Amine bin­ den kann und dabei wie bei jeden Chemisorption mit der Zeit aufgebraucht wird. Nach dem Waschen läßt sich durch einen Spülgang mit ca. 5-10% Zi­ tronensäure die ursprüngliche Kapazität jedoch wieder vollständig herstellen.
Die Kombination mit einer Adsorptionsschicht erlaubt weiter Körperemissionen zu unterbinden. Dabei kann die Adsorptionsschicht mit der Zitronensäure-im­ prägnierten Schicht verbunden sein oder als getrennte Schicht bzw. in Form eines elastischen Unteranzuges vorliegen. Die letztgenannte Version hat ge­ genüber einer Adsorptionsschicht mit einer imprägnierten Aktivkohle den gro­ ßen Vorteil, daß eine unimprägnierte Kohle immer eine bessere Adsorptionslei­ stung bringt als eine imprägnierte, wenn es sich um eine reine Physiosorption handelt. Die Imprägnierung stört immer die Zugängigkeit der Poren. Des wei­ teren braucht vom verschmutzten Anzug oft nur die äußere Schicht gewa­ schen werden.

Claims (2)

1. Reinraumanzug aus luftdurchlässigen, insbesondere wasserdampfdurch­ lässigen, partikeldichten Material, dadurch gekennzeichnet, daß das Mate­ rial mit Zitronensäure imprägniert ist, bzw. nach dem Waschen mit wäßri­ ger Zitronensäure nachimprägniert wird.
2. Reinraumanzug nach Anspruch 1, dadurch gekennzeichnet, daß eine zu­ sätzliche Adsorptionsschicht unter der imprägnierten Schicht vorhanden ist.
