Description

Filtaus BRir ödarVli$8'c&i<r Die Neuerung betrifft aua Papier oder Vlieepapier hergeetellte Filter zur Filtrierung flussiger oder gafyaiger Mdiwn nA Papiere zur Herstellung solcher Filter und bezweckt# diesen Pa- pieren oder Filtern eine grSßere meehanioohe Festigkeit und Be- ständigkeit gegen Alkalien und Ubluren zu geben. Neuerungegeaäß besteht daa Filter aus einem Filtrier-oder Filtriervliespapier das mit einer hochmolekularen waseerlwli- ohenDispersion auf Polya-thylenbaais getränkt ist die eelbst nach dem Tränken durch Auskondeasieren waaeerunl8alioh gemacht ist. Die zur Heratellung der Filter dienenden Papiere oder Vliese kennen aus Zellulose-oder Kunstatoffasern bestehen. Die Imprägnierung hat für die Filter bzw. für die Filtrierpapiere oder Filtriervlieepapiere den Vorteil, daß ihre mechanisobe Festigkeit herautgesetzt wird. Für aus ZelluloM bestehende Fil- trierpapiere oder Filtriervlieapapiere wird gleichseitig die Be- ständigkeit gegen Alkalien oder Säuren wesentlich erhöht. Man kann jetzt mit diesen Papieren Medien filtern, fir die bisher Filter anderer Art verwendet werden mHaaen. Mn weiterer Vorteil der imprägnierten Papiere ist, daß sie miteinander versohweißbar sind. Das erleichtert die Hersteilung von Filtern in Behälterferm, z. B. von Filtertrichtern oder Filtertaten. Filter aus imprägnierten Papieren eignen sieh aosh besondere zor Filtrierung von Gaaen. Sie erhalten beim DarohetrSaea der Saae eine hohe statische Aufladung. die das Niederschlagen fester Teilchen auf den Filtern begünstigt. Die Imprägnierung aetzt die Filtrierfahigkeit der Papiere etwa* herab, aber dieae Minderung bleibt in erträglichen Grenzen. Ludern kannen dank der erUieren mechanisohe Festigkeit der imprägnierten Filter dttnnere und somit porbeort Papiere zu ihrer Herstellung verwendet werden. Dieanliegenden Mualer zeigen ala AH8f ! ihrungsbeispiel in Trichter- formgefaltete Filter, die aua entapreohend der Neaerung iapräg- nierten Papieren hergestellt aind. Die Muster laaaen erkennen, daßgegena. ber niohtimprägnierter Filtern die meehaniaehe Featig- keit erhöht ist, daß aber andererseits die Papiere ihre Piltrier- fähigkeit behalten. Auch die hohe Beständigkeit gegen Alkalien und Säuren lUt eich an Hand der Maater nachweisen. Imprägnierte Filter sind zunächst wasserabweisend, aber aie ver- lierendiese Eigenschaft nach einer ausreichenden Benetzung, daa anfänglich hydrophobe Verhalten behindert ihre Verwendung als Zwei weitere Master zeigen Filter-und Filtervlieapapiere in runderFoza. . 9-. ch t Sohnzanspoh !

The new filter consists of a filter or filter Filter fleece paper with a high molecular weight waseerlwli- Without dispersion soaked on polythylene base, it is self made waaeerunl8alioh by condensing out after soaking is. The papers or fleeces used to manufacture the filters know are made of cellulose or synthetic fibers. The impregnation has for the filter or for the filter papers or filter fleece papers have the advantage that their mechanisobe Strength is increased. For fil- trier papers or filter fleece papers, the loading Resistance to alkalis or acids is significantly increased. Man can now filter media with these papers, for those previously Filters of other types are used mHaaen. Mn another advantage of the impregnated papers is that they can be welded together are. This facilitates the production of filters in container ferm, z. B. of filter funnels or filter actions. Filters made of impregnated paper are suitable see aosh special zor Filtration of Gaaen.
