Abstract
Description
Es ist bekannt filternde Körper und/oder Flächen aus Staubfiltern dauerhaft gegen eine Verkeimung oder Verpilzung zu sichern.It is known filtering bodies and / or surfaces from dust filters permanently against one To ensure germs or fungi.
Hierauf bezieht sich insbesondere die Patenschrift DE 42 08 243.C1.The patent specification DE 42 08 243.C1 relates in particular to this.
Damit Filtermaterial das außer einer rüttelnden Reinigung auch eine Reinigung durch Abwaschen erfahren soll und gleichzeitig hierbei wieder eine denaturierende Aktivität ermöglicht die durch Staubüberlagerung abgeschwächt ist, wird erfindungsgemäß vorgeschlagen, in einer Kunststoffmasse denaturierende Materialien unterzumischen wie z. B. Natriumcarbonat und/oder Kaliumcarbonat vorzugsweise in Form von Salzen, wobei die Kunststoffbeschichtung selbst porös gestaltet ist um einen entsprechenden Luftdurchgang zu ermöglichen.So that filter material besides shaking cleaning also cleaning by washing should experience and at the same time again a denaturing activity enables the through Dust coverage is weakened, is proposed according to the invention in a Mix in plastic mass denaturing materials such. B. sodium carbonate and / or Potassium carbonate preferably in the form of salts, the plastic coating itself being porous is designed to allow appropriate air passage.
Durch das Auflagern von Stäuben wird zwangsläufig die denaturierende Aktivität nach lassen jedoch wird durch Abwaschen und damit Freisetzen von denaturierenden vorzugsweise salzhaltigen Oberflächen die durch die Feuchtigkeit noch zusätzlich aktiviert werden, eine größtmögliche Denatuierung bei gleichzeitigem Luftfiltereffekt erzielt.By storing dust, the denaturing activity is inevitably reduced however, washing off and thus releasing denaturing agents is preferred saline surfaces that are additionally activated by the moisture, a the greatest possible denaturation with simultaneous air filter effect.
Weiterhin wird erfindungsgemäß vorgeschlagen das für eine flammwidrige Ausführung die Zuschlagstoffe zusätzlich flammwidrig gemacht werden. Furthermore, the invention proposes that for a flame-retardant design Aggregates are also made flame retardant.
In einer weiteren Ausgestaltung ist es möglich das salzförmige Stäube in die Kunststoffmenge mit eingearbeitet werden und infolgedessen nicht nur eine denaturierende sondern auch poröse Eigenschaft des Filtermaterials bewirken.In a further embodiment, it is possible to include the salt-like dusts in the amount of plastic are incorporated and consequently not only a denaturing but also porous Effect property of the filter material.
Gleichzeitig wird erfindungsgemäß vorgeschlagen das die Porengröße der Beschichtung entsprechend der gewünschten Filterklasse auch durch Einmengen von entsprechenden Festkörpern vorzugsweise in denaturierender Ausführung in die Kunststoffmasse erzielt werden und das das Material selbst z. B. durch eine spätere Nadelung porös gehalten werden kann.At the same time, it is proposed according to the invention that the pore size of the coating according to the desired filter class also by adding appropriate ones Solids are preferably achieved in denaturing execution in the plastic mass and that the material itself z. B. can be kept porous by later needling.
Weiterhin wird erfindungsgemäß vorgeschlagen das vorzugsweise Polyurethan mit denaturierenden Salzen mit Natriumcarbonat und/oder Kaliumcarbonat insbesondere in Kristallform als Zuschlagstoffe in das Gemenge von Kunststoffen und Zuschlagstoffen eingemischt werden kann.Furthermore, the invention preferably proposes using polyurethane denaturing salts with sodium carbonate and / or potassium carbonate especially in Crystal form as additives in the mixture of plastics and additives can be mixed in.
Diese erfindungsgemäße Beschichtung kann natürlich auch nicht nur für filternde Flächen Anwendung finden, sondern auch für Innenauskleidungen wo z. B. die Gefahr einer Verpilzung oder von Bakterienbefall gegeben ist.This coating according to the invention can of course not only be used for filtering surfaces Find application, but also for interior linings where z. B. the risk of fungal growth or is caused by bacteria.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen ein Verfahren zur Herstellung von denaturierenden Beschichtungen auf Filterflächen zu verwenden das diese Filterflächen mit einer Kunststoffmasse beaufschlagt werden, die denaturierende Eigenschaften aufweist und abwaschbar ist, die Kunststoffmasse mit denaturierenden salzförmigen Massen vermischt ist, die Beschichtung porös gestaltet wird wobei insbesondere salzhaltige Feinstteile z. B. aus Natriumcarbonat eingemengt sind, die Porengröße der Beschichtung vorzugsweise auch durch eine spätere oder vorher vorgesehene Nadlung des Grundmaterials besteht und das die denaturierenden Stoffe nicht nur durch denaturierende Zuschlagstoffe denaturierend ausgebildet sind, sondern zusätzlich durch flammhemmende oder flammwidrige Stoffe, oder schwerentflammbar ausgeführt sind.Of course, the invention is not limited to that described in detail above and limited forms of training shown, but there are numerous changes possible, without however deviating from the basic idea of a method for producing to use denaturing coatings on filter surfaces that filter surfaces with a Plastic mass are applied, which has denaturing properties and is washable, the plastic mass is mixed with denaturing salt-like masses Coating is designed porous, in particular saline fines z. B. from Sodium carbonate are mixed in, the pore size of the coating preferably also by there is a later or previously intended needling of the base material and that denaturing substances not only denaturing through denaturing additives are, but also by flame retardant or flame retardant substances, or flame retardant.
