filtre en mousse c\u00e9ramique<\/a>, \u00e9valuez avec soin la surface sp\u00e9cifique effective ou la porosit\u00e9 de la mousse. Vous pouvez observer l'\u00e9tat d'homog\u00e9n\u00e9isation de la surface maill\u00e9e de la plaque filtrante, puis examiner l'\u00e9tat d'homog\u00e9n\u00e9isation de la maille en coupe transversale. Si possible, la porosit\u00e9 peut \u00eatre calcul\u00e9e par la m\u00e9thode de drainage. La grille tridimensionnelle est uniforme et la porosit\u00e9 est relativement importante, ce qui en fait une excellente plaque filtrante en c\u00e9ramique.<\/p>\n![\"\"](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/03\/Choose-Ceramic-Foam-Filter.jpg\")

Optez pour les filtres en mousse c\u00e9ramique<\/p>\n
La transmittance correspond \u00e0 la surface filtrante effective du filtre en c\u00e9ramique alv\u00e9ol\u00e9e. Plus la transmittance lumineuse est \u00e9lev\u00e9e, moins il y a de trous borgnes et plus les alv\u00e9oles filtrantes sont efficaces, meilleur est l'effet filtrant.<\/p>\n
Placez le filtre en mousse c\u00e9ramique \u00e0 inspecter sur une table lumineuse \u00e9quip\u00e9e d\u2019une ampoule \u00e0 incandescence de 200 W, puis utilisez une plaque carr\u00e9e en plastique transparent de 5,0 \u00d7 5,0 mm de c\u00f4t\u00e9 pour mesurer la surface de la grande face du filtre en vue des calculs et des essais. La transmittance lumineuse de la plaque filtrante sert \u00e0 d\u00e9terminer la transmittance lumineuse de celle-ci. Dans la pr\u00e9sente norme, la transmittance (taux de perforation) de la plaque filtrante est sp\u00e9cifi\u00e9e \u00e0 95% ou plus.<\/p>\n
La porosit\u00e9 correspond au pourcentage du volume total des cavit\u00e9s d'une plaque filtrante par rapport au volume total de cette derni\u00e8re. La porosit\u00e9 d\u00e9termine la capacit\u00e9 de filtration de la mousse c\u00e9ramique par unit\u00e9 de volume. Plus la porosit\u00e9 est \u00e9lev\u00e9e, plus le d\u00e9bit de filtration de la plaque filtrante est important, et plus sa capacit\u00e9 de filtration est \u00e9lev\u00e9e.<\/p>","protected":false},"excerpt":{"rendered":"
