A kind of high temperature resistant (400-850 ℃), corrosion-resistant, lower resistance, its tunica fibrosa can be at outer surface, gradient ceramics with ceramic fibrous membrane fenestrata that also can be on inner surface.It is to be aggregate by corundum or alumina or quartz or alumina silicate porcelain or SiC.Make cellular ceramic substrate with the medium and high temperature bond through high-temperature calcination, then with alumina silicate fibre or high aluminum fiber or these two kinds composite fibre of mixing by a certain percentage, through short cutting, homogenizing, being dispersed in and being added with waterglass or Ludox or aluminum solutions or aluminum phosphate or they the aqueous solution by the formulated mixed liquor of different proportion, it is coated on the cellular ceramic substrate, then drying, burn till and make the pottery of ceramic fibre fenestra gradient.
Description
The invention belongs to the silicate engineering, fine ceramics and function ceramics field.
Before as the filtration of high temperature dust gas etc., adopt the glass fibre cloth bag mostly, high temperature resistant only below 350 ℃, because of the glass fibre cloth bag eventually so the flue gas that is higher than more than 350 ℃ all needs after the water spray cooling, could make filtration, purification handles, both wasted water like this, contaminated environment and cause unnecessary heat waste adopts resistant to elevated temperatures porous ceramics to make filtering material again, though can address the above problem, but because of resistance is big, the regeneration difficulty, and can not apply.
The objective of the invention is to: provide a kind of anti-400 ℃-850 ℃, low filtration resistance, high separating efficiency and the gradient ceramics with ceramic fibrous membrane fenestrata of easily regenerating, it can be widely used in high-temperature flue gas and do aspects such as dedusting, makes the high-temperature resistant medium filtering material.
Fig. 1-1 is a cellular ceramic substrate, and Fig. 1-2 is the ceramic fibre film.
Accompanying drawing 2, flanged gradient ceramics with ceramic fibrous membrane fenestrata.
Fig. 2-1 is the high strength mounting flange, and Fig. 2-2 is a cellular ceramic substrate, and Fig. 2-3 is the ceramic fibre film, and Fig. 2 (a) is the band gradient ceramics with ceramic fibrous membrane fenestrata at the end.Fig. 2 (b) is not for the gradient ceramics with ceramic fibrous membrane fenestrata at the end.
