摘要
A honeycomb ceramic filtration substrate, a filter made of the said substrate and a filter system made of the said filter and their production methods are published in the present invention. The said substrates are extruded with a paste comprising (by portion): SiC: 1; Clay: 0.05-0.5; Flour: 0.1-0.35; grease: 0.025-0.05; Water: 0.2-0.35. The said sintered substrate has a honeycomb structure with cells density ranging from 4˜62 cells/cm2; The cell wall thickness is: 0.2-1.2 mm; The porosity of the cell wall: 40-70%. The cell wall through pore rate is more than 30%; The average diameter distribution of the cell wall micro-pores is in the ranging of 1-50 μm. The said substrate can be designed in different cylinders whose cross section are in form of square, one border curved square and one border curved triangle etc., After adhering the substrates, the filter can be used as vehicle particulates filter. After the canning of the filter, the filter system is produced. The problem of particulates pollutant from the vehicles can be resolved via the present invention, and it is especially efficient to treat the diesel exhaust particulates which are harmful to the human health.
