Title
(EN) METHODS OF MAKING PLUGGED HONEYCOMB BODIES WITH CEMENT PATTIES
(FR) PROCÉDÉS DE FABRICATION DE CORPS EN NID D'ABEILLES OBTURÉS AVEC DES GALETTES DE CIMENT
Abstract
(EN)
A method of plugging a honeycomb body includes mixing a plugging mixture at a mixing temperature, wherein the plugging mixture comprises a plurality of inorganic particles, inorganic binder, organic binder, and water; dispensing the plugging mixture into a patty mold at a dispensing temperature; cooling the plugging mixture within the patty mold to a cooled temperature, such that a cement patty is formed; and pressing the cement patty into a plurality of channels in a honeycomb body, wherein the mixing temperature and the dispensing temperature are above a hydration point temperature of the organic binder in the plugging mixture, and the cooled temperature is below the hydration point temperature of the organic binder in the plugging mixture.
