Abstract

A paper having a basis weight in the range from 75 to 100 g/m<2>, which contains from 85 to 98 % by weight of cellulose and from 15 to 2 % by weight of an inert plastic, based on the total dry weight = 100, is composed of at least two layers held together by a honeycomb structure and serves for filtering aqueous and nonaqueous solutions.

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.There are a wide variety of types of paper filters for a variety of uses known, the types of paper are adapted to the particular use. In addition, it is also known to use special types of paper for the production of cleaning cloths and disposable items such as coats, bed linen and the like, for example in the medical field. These are papers with a basis weight in the range from 75 to 100 g / m 2 , which contains 85 to 98% by weight of cellulose and 15 to 2% by weight of plastic, based on the total dry weight = 100, and from at least two layers held together by a honeycomb structure is put together.

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.It has now surprisingly been found that such paper with a weight per unit area in the range from 75 to 100 g / m 2 , the 85 to 98% by weight of cellulose and 15 to 2% by weight of plastic, based on the total dry weight = 100, contains and composed of at least two layers held together by a honeycomb structure, is outstandingly suitable for the filtration of aqueous and non-aqueous liquids, in particular of oil such as lubricating oil or hydraulic oil in oil filter systems. Filters or filter cartridges produced using such papers not only have a high filtration effect, but also have the advantage that they are suitable in the same way for aqueous and non-aqueous liquids and are not easily clogged by suspended solids, which results in long useful lives and long service lives.

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.The use of this has proven to be particularly advantageous Papers for filtering lubricating oil in the printing circuit Lubrication of internal combustion engines has been proven as both Water and soot particles are extremely effective the circulating lubricating oil are removed, namely for downtimes or useful lives as usual wise for the oil filters that are in the Circulation pressure lubrication of internal combustion engines installed will.

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.A suitable filter paper of this type is, for example, the filter paper sold by Scott Paper under the name "Hiloft 3051, Wypall, Itex Software"; Scott Plaza; Philadelphia, United States. This filter paper has a basis weight of 85 to 90 g / m 2 and consists of 94 wt .-% cellulose and 6 wt .-% of an indifferent plastic, each based on the total dry weight = 100. Two crosswise layers are separated by a Honeycomb structure of approx. 1 mm diameter held together. The absorption capacity of this paper for water, petrol and oil is more than twice its own weight.
