Description
Es sind die verschiedensten Arten von Papierfiltern
für die unterschiedlichsten Verwendungszwecke bekannt,
wobei die Papierarten an den jeweiligen Verwendungs
zweck angepaßt sind. Darüber hinaus ist es auch bekannt,
besondere Papiersorten zur Herstellung von Putztüchern
und von Einwegartikeln wie Kitteln, Bettwäsche und
dergleichen zum Beispiel im medizinischen Bereich zu
verwenden. Es handelt sich dabei um Papiere mit einem
Flächengewicht im Bereich von 75 bis 100 g/m2, das
85 bis 98 Gew.-% Cellulose und 15 bis 2 Gew.-% Kunst
stoff, bezogen auf das Gesamttrockengewicht = 100,
enthält und aus mindestens zwei durch eine Waben
struktur zusammengehaltenen Schichten zusammengelegt
ist.
Es wurde nun überraschenderweise gefunden, daß solches
Papier mit einem Flächengewicht im Bereich von 75 bis
100 g/m2, das 85 bis 98 Gew.-% Cellulose und 15 bis
2 Gew.-% Kunststoff, bezogen auf das Gesamttrocken
gewicht = 100, enthält und aus mindestens zwei durch
eine Wabenstruktur zusammengehaltenen Schichten zusam
mengelegt ist, hervorragend zur Filtraton von wäßrigen
und nichtwäßrigen Flüssigkeiten, insbesondere von Öl
wie Schmieröl oder Hydrauliköl in Ölfilteranlagen ge
eignet ist. Unter Verwendung solcher Papiere hergestellte
Filter oder Filterpatronen haben nicht nur eine hohe
Filtrationswirkung, sondern besitzen den Vorteil, daß
sie in gleicher Weise für wäßrige wie für nichtwäßrige
Flüssigkeiten geeignet sind und sich nicht leicht durch
suspendierte Feststoffe zusetzen, woraus lange
Nutzungsdauern und hohe Standzeiten resultieren.
Als besonders vorteilhaft hat sich die Verwendung dieses
Papiers zum Filtrieren von Schmieröl in der Druckumlauf
schmierung von Verbrennungsmotoren erwiesen, da sowohl
Wasser als auch Rußteilchen außerordentlich wirksam aus
dem umlaufenden Schmieröl entfernt werden, und zwar
bei Standzeiten oder Nutzungsdauern wie sie üblicher
weise für die Ölfilter verlangt werden, die in die
Druckumlaufschmierung von Verbrennungsmotoren eingebaut
werden.
Ein geeignetes Filtrierpapier dieser Art ist zum Beispiel
das unter der Bezeichnung "Hiloft 3051, Wypall, Itex
Software" vertriebene Filtrierpapier der Firma Scott
Paper; Scott Plaza; Philadelphia, USA. Dieses Filtrier
papier hat ein Flächengewicht von 85 bis 90 g/m2 und
besteht zu 94 Gew.-% Cellulose und 6 Gew.-% aus einem
indifferenten Kunststoff, jeweils bezogen auf das Gesamt
trockengewicht = 100. Zwei kreuzweise zusammengelegte
Schichten werden durch eine Wabenstruktur von ca. 1 mm
Durchmesser zusammengehalten. Die Aufnahmefähigkeit
dieses Papiers für Wasser, Benzin und Öl beträgt mehr
als das Doppelte des Eigengewichtes.
Claims (3)
1. Verwendung von Papier mit einem Flächengewicht im
Bereich von 75 bis 100 g/m2, das 85 bis 98 Gew.-%
Cellulose und 15 bis 2 Gew.-% eines indifferenten
Kunststoffes, bezogen auf das Gesamttrockengewicht
= 100, enthält und aus mindestens zwei durch eine
Wabenstruktur zusammengehaltenen Schichten zusammen
gelegt ist, zum Filtrieren von wäßrigen und nicht
wäßrigen Flüssigkeiten.
2. Verwendung des Papiers nach Anspruch 1 zum Fil
trieren von Öl in Ölfilteranlagen.
3. Verwendung des Papiers nach Anspruch 2 zum Fil
trieren von Öl in der Druckumlaufschmierung von
Verbrennungsmotoren.
