METHOD AND SYSTEM FOR CRACK-FREE DRYING OF HIGH STRENGTH SKIN ON A POROUS CERAMIC BODY

A method and system to dry crack-free and high strength skin including an inorganic binder of an average particle size (D50) in a range between 10 nm and 700 nm on a porous ceramic body. The method includes supporting the honeycomb body on an end face such that axial channels and outer periphery are...

Beschreibung
Zusammenfassung:	A method and system to dry crack-free and high strength skin including an inorganic binder of an average particle size (D50) in a range between 10 nm and 700 nm on a porous ceramic body. The method includes supporting the honeycomb body on an end face such that axial channels and outer periphery are substantially vertical. A gas is flowed past the honeycomb body substantially parallel to the axial channel direction, substantially equally around the outer periphery of the skin, to uniformly dry the skin to form a partially dried skin under mild conditions. Then the partially dried skin may be dried more severely resulting in rapidly dried crack-free and high strength skin.
