改进的过滤元件
摘要：
本发明提供一种陶瓷过滤元件，所述过滤元件由主要包含长度为100～150μm、粗度1～5μm的无机纤维的絮凝浆体制成。该浆体还包含长度为10mm或更长的无机纱，例如长度为10～150mm，粗度为0.1～0.5mm的直径。该浆体在水中形成，水添加有硅胶和淀粉以絮凝该浆体。絮凝的浆体然后被注射到包括适当造型的网模的模具中，并且水被真空装置去除，由此形成的过滤器在烘炉中以120℃干燥8到12小时。纱可以为玻璃或氧化铝单丝或多丝纱，这种纱的添加增强了所生产的陶瓷过滤元件的抗冲击性。
摘要（英）：

A ceramic filter element is formed from a flocculated slurry predominantly containing inorganic fibres, of 100 to 150 [mu]m length and l to 5 [mu]m thickness. The slurry also contains inorganic yarn in lengths of from 10 mm or greater, e.g. 10 to 150 mm and thickness 0.1 to 0.5 mm diameter. The slurry is formed in water with colloidal silica and starch added to flocculate the slurry. The flocculated slurry is then injected to a mould comprising an appropriately shaped mesh form, and water removed by vacuum, and the filter thus formed dried in an oven for 8 to 12 hours at 120 DEG C. The addition of yarns, which may be glass or alumina mono or multifilament yarns, increases the shock resistance of the ceramic filter element produced.
