Honeycomb ceramic with high porosity, thin wall and high strength as well as preparation method and application of honeycomb ceramic
The invention discloses a high-porosity, thin-wall and high-strength honeycomb ceramic as well as a preparation method and application thereof. Metal silicon is added into an inorganic raw material of the high-porosity, thin-wall and high-strength honeycomb ceramic to completely replace or partially replace silicon dioxide. Silicon dioxide is replaced by metal silicon, so that the purposes of reducing the wall thickness of the honeycomb ceramic, improving the porosity and improving the strength of the carrier can be achieved, the technical problems caused by back pressure rise of a treatment system and low strength of the honeycomb ceramic after upgrading of future regulations are solved, and the contradictory points of thin wall, high porosity and high strength are overcome; the honeycomb ceramic with the thin wall of 2-9 mil and the porosity of 45-65% is developed, guarantee is provided for the diversified requirements of the Europe 7 and national 7 markets, and air pollution treatment is assisted.
本发明公开了一种高孔隙率、薄壁、高强度蜂窝陶瓷及其制备方法与应用，所述高孔隙率、薄壁、高强度蜂窝陶瓷的无机原料中加入有金属硅来完全替代或部分替代二氧化硅。通过由金属硅替代二氧化硅，这样可实现减薄蜂窝陶瓷壁厚、提高孔隙率的同时提高载体强度的目的，解决了随着未来法规的升级后处理系统背压升高以及蜂窝陶瓷强度低带来技术难题，克服了薄壁、高孔隙率、高强度这些矛盾点，开发2mil‑9mil薄壁、45‑65%孔隙率的蜂窝陶瓷，为欧七、国七市场的多元化需求提供了保障，助力了大气污染治理。
