Disclosed are cement compositions for applying to honeycomb bodies as a plugging cement composition, segment cement, or even as an after-applied artificial skin or coating. The cement compositions generally comprise an inorganic powder batch mixture; an organic binder; a liquid vehicle; and a gelled inorganic binder. Also disclosed are honeycomb bodies having the disclosed cement compositions applied thereto, and methods for making same.

Pulling rolls for used in forming glass ribbons with reduced defects and cracking are disclosed. In one embodiment, the pulling roll may include a shaft member and a roll assembly. The roll assembly may be positioned on the shaft member for rotation with the shaft member. The roll assembly may include an axially compressed stack of ring elements formed from an inorganic material such as mica paper. The mica paper may include layers of overlapping mica platelets oriented substantially in parallel with one another. A contact surface of the roll assembly may have a Shore D hardness greater than or equal to about 10 and less than or equal to about 60.
摘要:
A method of forming a templated casting involves incorporating a liquid feedstock into the channels of a honeycomb substrate to form a feedstock-laden substrate, and directionally solidifying the liquid feedstock within the channels.
摘要:
Disclosed is a device for processing fluids, the device comprising an extruded body having multiple elongated cells therein, the body having a first fluidic passage therethrough defined principally within at least some of said cells, the first fluidic passage having a longitudinally serpentine path back and forth along the at least some of said cells.
摘要:
Disclosed are ceramic honeycomb articles which are composed predominately of a crystalline phase cordierite composition. The porous cordierite ceramic honeycomb articles has a plurality of cell channels and intersecting porous walls and possess a microstructure characterized by a pore size distribution wherein greater than or equal to 75% of the pore size distribution of the porosity of the porous walls, by volume, have a pore diameter (dv) wherein dv
摘要:
Sorbent substrates for CO2 capture and methods for forming the same are disclosed. In one embodiment, a method for forming a sorbent substrate for CO2 capture may include forming a plurality of matrix rods from a sorbent material and forming a plurality of channel rods from a support material. The plurality of matrix rods may then be co-extruded with the plurality of channel rods to form a plurality of sorbent filaments comprising a matrix of the sorbent material in which channels of support material are positioned such that the channels extend in an axial direction of each of the plurality of sorbent filaments. The plurality of sorbent filaments may then be stacked to form a filament assembly in which the plurality of sorbent filaments are axially aligned. Thereafter, the plurality of sorbent filaments of the filament assembly may be bonded to one another to form the sorbent substrate.
