METHODS OF MAKING PLUGGED HONEYCOMB BODIES WITH CEMENT PATTIES

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. 一种对蜂窝体进行堵塞的方法包括：在混合温度下混合堵塞混合物，其中，所述堵塞混合物包括多个无机颗粒，无机粘结剂，有机粘结剂和水；在分散温度下将堵塞混合物分配到饼模具中；在饼模具中将堵塞混合物冷却到冷却温度，形成胶合饼；以及将胶合饼压到蜂窝体中的多个通道中，其中，混合温度和分配温度高于堵塞混合物中的有机粘结剂的水合点温度，并且冷却温度低于堵塞混合物中的有机粘结剂的水合点温度。
