Title (EN) CERAMIC FOAM FILTER AND MANUFACTURING METHOD THEREOF
(FR) FILTRE EN MOUSSE DE CÉRAMIQUE ET PROCÉDÉ DE FABRICATION CORRESPONDANT
(ZH) 一种泡沫陶瓷过滤器及其制造方法
Abstract:
(EN) A ceramic foam filter and a manufacturing method thereof. The ceramic foam filter comprises the following materials provided in respective weight percentages: 20-50% of a silicon carbide, 20-55% of a zirconium oxide, and 10-36% of a silicon oxide, wherein all figures are based on the total weight of the ceramic foam filter. The method for manufacturing the ceramic foam filter comprises the following steps:(a) providing a slurry comprising a silicon carbide, a zirconium oxide or zirconium oxide precursor, a silicon oxide or silicon oxide precursor, a binder, an optional additive, and a fluid carrier medium.; (b) applying the slurry to perform surface ornamentation of a perforated organic foam; (c) drying the perforated organic foam surface ornamented with the slurry to obtain a green body; and (d) sintering the green body in oxygen-containing air to obtain the ceramic foam filter.
(FR) L'invention concerne un filtre en mousse de céramique et un procédé de fabrication correspondant. Le filtre en mousse de céramique comprend les matériaux suivants, présents en pourcentages en poids respectifs : 20-50 % d'un carbure de silicium, 20-55 % d'oxyde de zirconium et 10-36 % d'un oxyde de silicium, tous les nombres étant basés sur le poids total du filtre en mousse de céramique. Le procédé de fabrication du filtre en mousse de céramique comprend les étapes suivantes, consistant à : a) utiliser une suspension comprenant un carbure de silicium, un oxyde de zirconium ou un précurseur d'oxyde de zirconium, un oxyde de silicium ou un précurseur d'oxyde de silicium, un liant, un additif facultatif et un milieu support de fluide ; (b) appliquer la suspension pour réaliser une décoration de surface d'une mousse organique perforée ; (c) sécher la surface de mousse organique perforée décorée par la suspension pour obtenir un corps cru ; et (d) fritter le corps cru dans de l'air contenant de l'oxygène afin d'obtenir le filtre en mousse de céramique.
(ZH) 一种泡沫陶瓷过滤器及其制造方法。按重量计,泡沫陶瓷过滤器包括:碳化硅20%~50%,氧化锆20%~55%,以及氧化硅10%~36%,均基于泡沫陶瓷过滤器的总重量。制造泡沫陶瓷过滤器的方法,包括以下步骤:(a)提供包括碳化硅、氧化锆或氧化锆前驱体、氧化硅或氧化硅前驱体、粘结剂、可选的外加剂、以及液体载体的浆料;(b)将浆料涂挂在开孔有机泡沫体上;(c)将涂挂有浆料的开孔有机泡沫体干燥,得到坯体;(d)含氧气氛下烧结坯体,得到泡沫陶瓷过滤器。
