Description

Verfahren zur Verhütung von Explosionen in Lacktrocknungsöfen In Lackierereien, besonders in solchen, die mit höheren Trockenlufttemperaturen bis zu 2.4o° im Ofenraum arbeiten, sind Ofenbrände keine Seltenheit, und zwar auch dann, wenn die Temperatur der Heizflächen etwa 32o° C nicht überschreitet, obwohl diese Temperaturen noch weit unter den bekannten Entzündungstemperaturen der Mischungen von Luft und dampfförmigenLacklösungsmittelnliegen. Untersuchungen auf diesem Gebiete haben nun gezeigt, daß Entzündungen durch herabfallende Lacktropfen eintreten, wenn diese auf erhitzte Eisenteile, deren Oxydschicht frei liegt, auffallen. Zu erklären ist diese Erscheinung durch die katalytische Wirkung von Eisenoxyden, welche die Entzündung der brennbaren Teile des Lackes weit unter den bekannten Zündungstemperaturen bewirken.Process to prevent explosions in paint drying ovens In paint shops, especially in those with higher drying air temperatures of up to 2.4o ° in the furnace work, furnace fires are not uncommon, even if the temperature the heating surfaces does not exceed about 32o ° C, although these temperatures are still are well below the known ignition temperatures of mixtures of air and vapor paint solvents. Studies in this area have now shown that inflammation by falling Lacquer drops occur when these are exposed to heated iron parts, their oxide layer lies, attract attention. This phenomenon can be explained by the catalytic effect of iron oxides, which far below the ignition of the combustible parts of the paint cause the known ignition temperatures.

Da die Tropfe.nbildung lackierter Teile durch Warmwerden im Ofen nicht verhindert «erden kann, werden gemäß der Erfindung innerhalb des Ofenraumes Tropfenfänger vorgesehen, die aus Stoffen bestehen, die keine katalytische Wirkung besitzen. Ganz besoalders geeignet ist hierzu Aluminium, dessen Oxyd in dieser Hinsicht vollkommen unwirksam ist.Because the dripping of painted parts when they get warm in the oven does not According to the invention, drip catchers are used within the furnace chamber provided, which consist of substances that have no catalytic effect. Quite Particularly suitable for this purpose is aluminum, the oxide of which is perfect in this respect is ineffective.

Das neue Verfahren bedeutet einen Fortschritt für alle Lackieröfen und ist besonders für fortlaufend beschickte Kanaltrockenöfen wichti z.The new process represents a step forward for all painting ovens and is especially important for continuously loaded tunnel drying ovens z.
