Honeycomb ceramic carrier material as well as preparation method and application thereof
The invention discloses a honeycomb ceramic carrier material as well as a preparation method and application thereof, and belongs to the technical field of diesel vehicle engine exhaust tail gas purification systems. The fused quartz honeycomb ceramic prepared by the invention is prepared by sintering amorphous fused quartz powder. The material has isotropic ultralow thermal expansion coefficient and high thermal shock resistance. The catalyst has good thermodynamic properties, high maximum tolerable temperature and high maximum carbon loading capacity. Secondly, the porosity of the fused quartz honeycomb ceramic can reach 40%-60%, the fused quartz honeycomb ceramic has low exhaust back pressure, various indexes meet the national VI emission requirements, and the fused quartz honeycomb ceramic has good application prospects. When the catalyst is applied to an automobile exhaust treatment system, the maximum carbon loading capacity is relatively high.
本发明公开了一种蜂窝陶瓷载体材料及其制备方法和应用，属于柴油车发动机排气尾气净化系统技术领域。本发明制备的熔融石英质蜂窝陶瓷是由非晶态的熔融石英粉末烧结而成的。具有各项同性的超低热膨胀系数及较高的抗热震性能。能够使其具有良好的热力学性能，最高耐受温度高，具有较高的最大碳载量。其次，本发明的熔融石英质蜂窝陶瓷，孔隙率可达到40％‑60％，具有较低的排气背压，各项指标满足国VI的排放要求，具有良好的应用前景。在应用在汽车尾气处理系统中时，具有较高的最大碳载量。
