| titleOfInvention | Process for convective treatment of plastic materials |
| abstract | This draft patent describes cleaning thinly appliednPlastic films, especially silicone polymer films, during thenCoating process on running substrate webs such as paper, foils,nMetal foils, textiles and fabrics; Composite substrates such as paper / film,nPaper / metal, foil / metal, textile / foil etc.n n n The favorable ratio of large surface area to low application weight (e.g. for silicone = 1 g / m 2 ) means that low-molecular impurities, such as inhibitors, catalyst residues from the manufacturing process, toxic substances, oligomeric and monomeric products or by-products from the still uncrosslinked Drive out plastic film by forced convection, through turbulent air layers in contact with the plastic-coated material web.n n n Die Luftgeschwindigkeit am Düsenausgang, die Strömungsgeschwindigkeit an dernAbsaugung, der Einfallswinkel der Luft auf die Materialbahn, die Strömungsrichtungnder Luft (mit, senkrecht oder gegen die Bahnlaufrichtung) die Geometrie der Düsennund der Abstand der Düsen zur Materialbahn. Die Strömungsverhältnisse werden amnPC simuliert und auf die Materialbahn übertragen. Die Austreibung der Verunreinigungen erfolgt vor dem eigentlichen Härtungsprozessnbei Raumtemperatur bis zur Temperatur unterhalb der Reaktionstemperaturnthermisch vernetzender Kunststoffe oder im Bereich der Vernetzungstemperatur oderndurch Abkühlung der Materialbahn im konvektiv wirkenden Teil des Trockners. Die Abnahme der Verunreinigungen wird durch Probenentnahme an der laufendennBahn gemessen. IR, ATR, NMR, RFA, DSC. Die Aushärtung der Kunststoffbeschichtung selbst erfolgt dann durch Warmluft oderndurch Zuführung energiereicher Strahlen wie (IR - UV- EB) oder durch diengleichzeitige Einwirkung von Warmluft und Energiestrahlen auf die beschichtetenSubstratbahn. Der Übergang von Konvektion und Aushärtung ist fließend. The following parameters are used in the convective part of the dryer to effectively remove the impurities: The air speed at the nozzle outlet, the flow speed at the suction, the angle of incidence of the air on the material web, the direction of flow of the air (with, perpendicular or against the web running direction), the geometry of the nozzles and the distance of the nozzles to the material web. The flow conditions are simulated on the PC and transferred to the material web. The impurities are expelled before the actual curing process at room temperature to the temperature below the reaction temperature of thermally crosslinking plastics or in the range of the crosslinking temperature or by cooling the material web in the convective part of the dryer. The decrease in impurities is measured by taking samples from the running web. IR, ATR, NMR, RFA, DSC. The plastic coating itself is then cured by warm air or by supplying high-energy rays such as (IR - UV-EB) or by the simultaneous action of warm air and energy rays on the coated substrate web. The transition from convection to curing is fluid. n n n Schnellere Aushärtung zu einem vernetzten Film, Aushärtung bei niedrigerennTemperaturen, thermische Schonung der Substrate, geringerer Anteil extrahierbarernBestandteile im Endprodukt, geringere Abhängigkeit der Aushärtegeschwindigkeit,nbei thermisch vemetzenden Produkten vom Flächengewicht des Substrates. Toxischnunbedenklichere Beschichtungen ( BGVV, FDA). Aushärtung der Kunststoffe, insbesondere bei additionsvernetzenden Siliconen, beingeringerem Katalysatorbedarf. Objective: The following convective cleaning of the applied plastic film, in particular by removing the inhibitor from silicones, achieves the following: Faster curing to a cross-linked film, curing at lower temperatures, thermal protection of the substrates, less extractable constituents in the end product, less dependency of the curing speed, with thermal cross-linking products on the basis weight of the substrate. Coatings that are less toxic (BGVV, FDA). Hardening of the plastics, especially in the case of addition-crosslinking silicones, with a lower catalyst requirement. |
