Abstract

The high-permeability filter bed with adsorptive properties comprises a thermoplastic mesh with adsorbents attached to both sides by an adhesive material. An Independent claim is also included for the production of the filter material by treating a thermoplastic mesh base with a moisture-crosslinking isocyanate prepolymer and squeezing the mesh, drawing the coated mesh through a bed of (preferably moistened) adsorbent and then crosslinking the adhesive, possibly by the action of atmospheric moisture.

Description

Die Hauptanmeldung beschreibt ein Flächenfilter bzw. Faltenfilter, welcher aus einem luftdurchlässigem Träger, ein Gitter aus einem thermoplastischen Kunst­ stoff, und daran fixierten körnigen Adsorbentien besteht. Der Kleber, bevorzug­ terweise hochviskose, praktisch lösemittelfreie Polyurethane, wird durch Ab­ quetschen aufgetragen, wonach der Träger durch ein Bett körniger Adsorben­ tien gefahren wird. Vor dem Aushärten können Abdeckmaterialien hinzugefügt werden.The main application describes a surface filter or pleated filter, which consists of an air permeable support, a grid made of a thermoplastic art material, and there are granular adsorbents attached. The glue, preferred tically highly viscous, practically solvent-free polyurethanes, is from Ab squeeze applied, after which the carrier through a bed of granular adsorbents tien is driven. Cover materials can be added before curing become.

Es wurde nun ein Weg gefunden je nach Seite im gleichen Durchgang zwei verschiedene Adsorbentien auftragen zu können, was eine Reihe von hoch in­ teressanten Anwendungsmöglichkeiten erlaubt. So ist beispielsweise Aktivkoh­ le ein sehr gutes Adsorbens für nicht oder mäßig flüchtige Stoffe. Für viele flüchtige Stoffe wie saure und alkalische Gase, die z. B. in der Reinraumtech­ nik unerwünscht sind, ist deshalb der Einsatz von imprägnierten Kohlen erfor­ derlich: Ein saure Imprägnierung (Phosphorsäure) für beispielsweise NH3 und eine basische Imprägnierung (Kaliumcarbonat) für beispielsweise SO2.A way has now been found to be able to apply two different adsorbents depending on the side in the same pass, which allows a number of highly interesting application possibilities. For example, activated carbon is a very good adsorbent for non or moderately volatile substances. For many volatile substances such as acidic and alkaline gases, e.g. B. are undesirable in clean room technology, the use of impregnated carbon is therefore neces sary: An acidic impregnation (phosphoric acid) for example NH 3 and a basic impregnation (potassium carbonate) for example SO 2 .

Als Adsorbens für basische und saure Gase eignen sich auch saure und basi­ sche Ionenaustauscher. Es lassen sich mit dem neuen Verfahren eine Reihe von Kombinationen erstellen, wovon hier nur einige genannt seien:
Acidic and basic ion exchangers are also suitable as adsorbents for basic and acidic gases. A number of combinations can be created with the new method, only a few of which are mentioned here:

  • - Aktivkohle/ unimprägnierte Aktivkohle - Activated carbon / non-impregnated activated carbon  
  • - Sauer imprägnierte Aktivkohle/basisch imprägnierte Aktivkohle- Acid impregnated activated carbon / basic impregnated activated carbon
  • - Aktivkohle/Kationenaustauscher- activated carbon / cation exchanger
  • - Aktivkohle/Anionenaustauscher- activated carbon / anion exchanger
  • - Kationenaustauscher/Anionenaustauscher.- cation exchanger / anion exchanger.

Grundsätzlich kommen als Adsorbens auch Molekularsiebe und poröse Poly­ mere in Frage.In principle, molecular sieves and porous poly come as adsorbents mere in question.

Die Herstellung solcher Kombinationsfilter soll an zwei Beispielen erläutert wer­ den:The production of such combination filters should be explained using two examples the:

Beispiel 1example 1

Ein 40 g/m2 schweres PP-Gitter mit 64, ca. 1 mm2 großen Öffnungen pro cm2 wurde mit einer Mischung aus 100 Teilen Impranil HS62 und 6,2 Teilen Impra­ fix HSC, beides Produkte der BAYER AG, abgequetscht (Abquetscheffekt 90%). Die Warenbahn wurde über einer Wanne mit Splitterkohle (∅0,6-0,8 mm) bestreut, die die Oberseite vollüber bedeckte; der nicht haf­ tende Überschuß wurde unter leichter Schrägstellung abgerüttelt. Die einseitig mit Splitterkohle abgedeckte Bahn wurde anschließend durch ein Bett von mit K2CO3 imprägnierter Kohle geführt, die an der klebrigen Unterseite hängen blieb und diese vollüber bedeckten. Danach wurde beidseitig ein 35 g/m2 schweres, mit einem aufgedruckten Schmelzkleberpunkt versehenen Polye­ stergewirk angelegt und dieses Sandwich in einer Flachkaschiermaschine bei 170°C zu einem sehr formstabilen Verbund auskondensiert. Das standfeste Material hatte eine Auflage von ca. 160 g/m2 reiner Aktivkohle und 180 g/m2 mit K2CO3 imprägnierter Kohle und wurde zu einem Faltenfilter mit sechs La­ gen pro cm bei einer Faltenhöhe von 5 cm verarbeitet. Der Filter zeichnete sich durch hohe Formstabilität, sehr gute Adsorptionswerte für organische Verbin­ dungen und SO2 sowie sehr hohe Luftdurchlässigkeit aus.A 40 g / m 2 PP grid with 64 openings of approx. 1 mm 2 per cm 2 was squeezed off with a mixture of 100 parts Impranil HS62 and 6.2 parts Impra fix HSC, both products from BAYER AG (squeezing effect 90%). The material web was sprinkled over a trough with splinter coal (∅0.6-0.8 mm), which covered the top completely; the non-sticking excess was shaken off with a slight inclination. The web, which was covered with splinter coal on one side, was then passed through a bed of coal impregnated with K 2 CO 3 , which got stuck on the sticky underside and covered it completely. Thereafter, a 35 g / m 2 heavy, with a printed hot melt adhesive point Polye stergewirk was created and this sandwich was condensed in a flat laminating machine at 170 ° C to a very dimensionally stable composite. The stable material had a circulation of approx. 160 g / m 2 of pure activated carbon and 180 g / m 2 of carbon impregnated with K 2 CO 3 and was processed into a pleated filter with six layers per cm at a pleat height of 5 cm. The filter was characterized by high dimensional stability, very good adsorption values for organic compounds and SO 2 as well as very high air permeability.

Beispiel 2Example 2

Das PP-Gitter des Beispiels 1 wurde mit Levacast 43131N der BAYER AG ab­ gequetscht (Abquetscheffekt 85%) und an seiner Oberseite mit angefeuchteter Splitterkohle (0,4-0,8 mm, 25% F) bestreut und der Oberschuß abgerüttelt.The PP lattice of Example 1 was made with Levacast 43131N from BAYER AG squeezed (squeezing effect 85%) and moistened on the top Scattered coal (0.4-0.8 mm, 25% F) sprinkled and the top shot shaken off.

Danach wurde die PP-Bahn durch ein Bett aus angefeuchteter Splitterkohle die mit K2CO3 imprägniert war (Trockenauflage 8 g K2CO3 pro 100 g Kohle) gezo­ gen, so daß die eine Seite des PP-Gitters mit Aktivkohle, die andere Seite mit imprägnierter Aktivkohle bedeckt war. Beide Seiten wurden mit einem sehr of­ fenen Polyestervlies (ca. 30 g/m2) abgedeckt. Die losen Fasern verhakten sich mit der Splitterkohle, hatten aber auch teilweise mit dem Kleber Berührung und dieses Sandwich wurde aufgewickelt. Die in der Kohle vorhandene Feuchtig­ keit bewirkte eine Vernetzung des Klebers innerhalb einer Stunde.Then the PP web was drawn through a bed of moistened coal which was impregnated with K 2 CO 3 (dry coating 8 g K 2 CO 3 per 100 g coal), so that one side of the PP lattice with activated carbon, the other Side was covered with impregnated activated carbon. Both sides were covered with a very open polyester fleece (approx. 30 g / m 2 ). The loose fibers got caught in the coal, but also had some contact with the glue and this sandwich was wound up. The moisture present in the coal caused the adhesive to crosslink within an hour.
