Zusammenfassung:A method of plugging channels of a honeycomb body and a honeycomb body including plugged channels. The method includes applying a shear force to a plugging mixture comprising a plurality of inorganic particles, an inorganic binder, a clay, and a liquid carrier to change a viscosity of the plugging mixture from a first viscosity before vibration to a second viscosity, the second viscosity being less than the first viscosity. The honeycomb body is placed in contact with the plugging mixture such that a portion of the plugging mixture having the second viscosity flows into the plurality of channels. The application of shear forces is reduced or stopped to increase the viscosity of the portion of the clogging mixture in the plurality of channels to greater than the first viscosity. 堵塞蜂窝体的通道的方法以及包括堵塞的通道的蜂窝体。所述方法包括向包含多个无机颗粒、无机粘结剂、粘土和液体载剂的堵塞混合物施加剪切力,以将堵塞混合物的粘度从振动前的第一粘度改变到第二粘度,所述第二粘度小于所述第一粘度。将蜂窝体放置成与堵塞混合物接触,以使得具有第二粘度的一部分堵塞混合物流到多个通道中。减少或停止施加剪切力,以使多个通道中的该部分的堵塞混合物的粘度增加到大于第一粘度。
