Abstract

Harnstoffeinspritzungen, dadurch gekennzeichnet, dass die Führung des Harnstoffes komplett oder teilweise eine Emaillebeschichtung aufweisen, die durch Nassauftrag mit Schlicker mittels Tauchen, Fluten, Spritzen und anschließendem Einbrennen von bis zu 1200°C hergestellt ist. Die Führung des Harnstoffes besteht in der Regel aus Behältern, Tanke, Rohr-Leitungen, Pumpen, Düsen und den Einspritzkammern, die unmittelbar mit der Harnstofflösung in Berührung kommen.Urea injections characterized in that the leadership of the urea completely or partially have an enamel coating by wet application with slip by means of dipping, flooding, spraying and then burn-in from up to 1200 ° C is made. The leadership of urea usually consists of containers, tank, pipe lines, pumps, Nozzles and the injection chambers directly with the urea solution in contact come.

Description

Die Harnstoffeinspritzung wird bei Verbrennungsmotoren und -anlagen eingesetzt. Sie dient zur Verminderung der Stickoxidkonzentration im Abgas. Sie besteht im wesentlichen aus Rohrleitungen, Behältern, Pumpen, Düsen und Kammern, die mit der Harnstofflösung in Kontakt kommen oder in die Harnstofflösung eingespritzt wird.The Urea injection is used in internal combustion engines and plants used. It serves to reduce the nitrogen oxide concentration in the exhaust. It consists essentially of pipelines, containers, pumps, Nozzles and Chambers containing the urea solution come into contact or injected into the urea solution.

Die Erfindung besteht darin die zuvor beschriebenen Komponenten mit einer oder mehreren Schichten glasartiger Struktur oder Emaille zu beschichten.The Invention consists in the components described above one or more layers of vitreous structure or enamel to coat.

Die Beschichtung kann durch verschiedene Beschichtungsmöglichkeiten aufgebracht werden.

  • 1. Nassauftrag mit Schlicker durch Fluten, Tauchen, Spritzen
  • 2. Pulverauftrag mit elektrostatischem Emailpulver. Auch Puesta genannt
  • 3. Elektrostatischer Tauchemaillierung
  • 4. Puderemaillierung
The coating can be applied by various coating options.
  • 1. Wet application with slip by flooding, dipping, spraying
  • 2. Powder application with electrostatic enamel powder. Also called Puesta
  • 3. Electrostatic dip enamel
  • 4. Powder enamel

Diese Beschichtung wird mittels einem geeigneten Brennofen bei einer Temperatur von bis zu 1200°C eingebrannt.These Coating is done by means of a suitable kiln at a temperature from up to 1200 ° C baked.

Das Trägermaterial kann aus NE-Metall, Stahl, rostfreiem Stahl oder aus keramischem Material bestehen. Die beschichtete Harnstoffeinspritzung ist Säuren- und Laugenbeständig. Die Beschichtung schützt das Trägermaterial vor Korrosion und bietet durch die glatte geschlossene Oberfläche weniger Möglichkeiten für Ablagerungen und Verstopfungen durch kristallierten Harnstoff.The support material Can be made of non-ferrous metal, steel, stainless steel or ceramic Material exist. The coated urea injection is acid and Alkali resistant. The coating protects the carrier material against corrosion and offers less possibilities thanks to the smooth, closed surface for deposits and blockages by crystallized urea.

Des weiteren besitzt die Beschichtung eine gute Temperaturbeständigkeit und kann somit auch z. B. im heißen Abgasstrom oder bei beheizten Leitungen oder Düsen der Harnstoffeinspritzung verwendet werden.Of Furthermore, the coating has a good temperature resistance and thus can also z. B. in the hot exhaust stream or heated Pipes or nozzles the urea injection can be used.

Die Beschichtung kann wahlweise auch mit einer Schmutzabweisenden Nanobeschichtung versehen werden, die das Abweisen der Partikel noch verstärkt.The Coating can optionally also with a dirt-repellent nano-coating be provided, which reinforces the rejection of the particles.
