Title (EN) CONTACTLESS LEVELING OF A WASHCOAT SUSPENSION
(FR) NIVELLEMENT SANS CONTACT D'UNE SUSPENSION D'ENDUCTION WASHCOAT
(DE) KONTAKTLOSE NIVELLIERUNG EINER WASHCOATSUSPENSION
Abstract:
(EN) The invention is directed to a process and an apparatus for coating substrates of motor vehicle exhaust gas catalysts. The invention particularly describes an improvement in such coating processes in which a suspension (washcoat) containing the catalytic material is applied to such a substrate (monolithic substrate) from above (metered charge process).
(FR) La présente invention concerne un procédé et un dispositif de revêtement de supports de catalyseurs de gaz d'échappement d'automobile. L'invention concerne en particulier une amélioration de ce type de processus de revêtement, laquelle consiste en ce qu'une suspension contenant un matériau à effet catalytique (washcoat) est appliquée ou distribuée (processus dit « metered charge ») sur un support de ce type (monolithe de substrat).
(DE) Die vorliegende Erfindung richtet sich auf ein Verfahren und eine Vorrichtung zur Beschichtung von Trägern von Autoabgaskatalysatoren. Insbesondere beschreibt die Erfindung eine Verbesserung in derartigen Beschichtungsprozessen, bei denen eine das katalytisch aktive Material enthaltende Suspension (Washcoat) auf einen solchen Träger (Substratmonolith) von oben appliziert bzw. aufgegeben wird (sogenannter "metered charge" Prozess).
