Abstract

The invention relates to the technical field of honeycomb ceramic straight-through carriers, and discloses a honeycomb ceramic reinforcing structure. The honeycomb ceramic reinforcing structure is characterized by comprising an inlet honeycomb ceramic surface and an outlet honeycomb ceramic surface, the inlet honeycomb ceramic surface and the outlet honeycomb ceramic surface are provided with first area lattices correspondingly, wherein the included angles ranging from 20 degrees to 70 degrees are formed between the first area lattices and the outer side wall, and chamfers are formed in the first area lattices; and the inlet honeycomb ceramic surface and the outlet honeycomb ceramic surface are further provided with second area lattices, wherein the included angles ranging from 0 degree to20 degrees and ranging from 70 degrees to 90 degrees are formed between the second area lattices and the outer side wall, and the hole wall thickness of the first area lattices is larger than the hole wall thickness of the second area lattices by 1%-80%. According to the honeycomb ceramic reinforcing structure, reinforcing is carried out in the bevel angle area, the wall thickness is increased, and the chamfers are additionally arranged, and therefore, the reinforcing effect can be guaranteed, and the good thermal shock resistance and relatively small back pressure can also be guaranteed.

Description

technical field [0001] The invention relates to the technical field of honeycomb ceramic straight-through carrier, in particular to a honeycomb ceramic reinforced structure. Background technique [0002] In order to meet the increasingly stringent requirements of exhaust emission regulations, the products of honeycomb ceramic through-carriers are gradually developing towards thinner walls and higher porosity. Among them, thin wall can bring many performance benefits, such as reducing pressure drop, reducing cold start time, etc. The wall thickness of the general through carrier has been reduced from 6mil (1mil=25.4 microns) more than 20 years ago to 4mil or 3mil, or even 2mil. Due to the reduction of wall thickness, the strength of honeycomb ceramics has been greatly affected. Due to the reduction of strength, defects will be caused in the process of product production, catalyst coating and packaging, and serious cracks will be caused, resulting in product loss. These def...
