As the cake layer grows thicker, the gaps on it become smaller and smaller, and many inclusions will be trapped on the surface and internal gaps of the cake layer. At the same time, the resistance of the filter plate to the aluminum liquid continues to increase. After reaching a certain level, it is difficult for the aluminum liquid to pass through the filter plate. At this time, the filter plate should be scrapped. During the filtration process, the obvious change into the cake mode is the gradual increase in the pressure of the molten aluminum.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-373\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/04\/Filter-Box.jpg\" alt=\"\u0635\u0646\u062f\u0648\u0642 \u0627\u0644\u062a\u0635\u0641\u064a\u0629\" width=\"800\" height=\"600\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/04\/Filter-Box.jpg 800w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/04\/Filter-Box-300x225.jpg 300w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/04\/Filter-Box-768x576.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Deep_Bed_Filtration\"><\/span>Deep Bed Filtration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Deep bed filtration: When the inclusions that are much smaller than the filter pore size enter the ceramic filter plate with the aluminum liquid, they are captured by the inner wall of the filter plate pore size. The thicker the filter plate, the greater the effect of this model. This mode can filter out inclusions around 20um in size.<\/p>\n<p>Whether the deep bed mode occurs depends mainly on whether the inclusion particles can be retained after colliding with the inner wall of the filter plate. The path in the filter plate is tortuous and rough. When the aluminum liquid passes through the tortuous and communicating holes in the ceramic filter plate, the internal inclusions are deposited under the action of hydrodynamics, inertia, interception, collision, adsorption, etc. On the wall of the channel, so as to get clean aluminum liquid.<\/p>\n<p>In addition, the ceramic filter plate is not simply a mechanical barrier to inclusions, but physical and chemical adsorption, micropores, and chemical adsorption on the inner wall of the filter plate also promote the retention of inclusions. Therefore, the size of the filtered inclusions is much smaller than the size of the filter plate holes.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1397\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/8.jpg\" alt=\"Deep Bed Filtration\" width=\"500\" height=\"400\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/8.jpg 500w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/8-300x240.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Three_Filtration_Mechanisms\"><\/span>Three Filtration Mechanisms<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When filtering with ceramic filter plates, the above three mechanisms are combined.
