Quelle est l'utilisation des billes d'alumine activ\u00e9e ?<\/h2>\n

Ceux qui ne le savent pas ne l'ont peut-\u00eatre jamais vu. L'apparition de billes d'alumine<\/a> est une particule sph\u00e9rique blanche qui ressemble \u00e0 des boules de riz glutineux. Il s'agit d'une sorte de surface poreuse, hautement dispers\u00e9e et lisse, d'une r\u00e9sistance m\u00e9canique \u00e9lev\u00e9e, d'une forte absorption de l'humidit\u00e9 et d'une absorption de l'eau. Il est non toxique, inodore, insoluble dans l'eau et l'\u00e9thanol, et a une forte capacit\u00e9 d'adsorption du fluor. C'est un mat\u00e9riau solide qui ne se dilate pas, ne se fissure pas et reste intact. Il est largement utilis\u00e9 comme d\u00e9shydratant ou comme catalyseur pour les r\u00e9actions chimiques, comme support de catalyseur et pour la purification des gaz. L'adsorbant, l'\u00e9liminateur de fluorure pour l'eau potable, l'\u00e9liminateur de couleur et d'odeur pour les eaux us\u00e9es industrielles, etc.<\/p>\n

1. Le processus de production de billes d'alumine activ\u00e9e<\/a><\/strong><\/p>\n

La principale mati\u00e8re premi\u00e8re pour la production de billes d'alumine activ\u00e9e est la poudre d'hydroxyde d'aluminium, qui est une mati\u00e8re chimique commune non toxique, inodore et non corrosive. \u00c0 l'heure actuelle, la m\u00e9thode Bayer est la plus populaire et la plus utilis\u00e9e. Le principe de base consiste \u00e0 utiliser une solution concentr\u00e9e d'hydroxyde de sodium pour convertir l'hydroxyde d'aluminium en aluminate de sodium, \u00e0 diluer et \u00e0 ajouter des cristaux de semences d'hydroxyde d'aluminium pour repr\u00e9cipiter l'hydroxyde d'aluminium, et \u00e0 pulv\u00e9riser l'hydroxyde d'aluminium produit par broyage. Apr\u00e8s traitement, la boule est fritt\u00e9e \u00e0 haute temp\u00e9rature dans un four pour fabriquer des boules d'alumine activ\u00e9e ou d'autres types de produits de la s\u00e9rie alumine activ\u00e9e.<\/p>\n

2. l'utilisation de billes d'alumine activ\u00e9e<\/strong><\/p>\n

Elle est largement utilis\u00e9e comme catalyseur et support de catalyseur dans l'industrie p\u00e9trochimique et l'industrie des engrais. L'alumine activ\u00e9e moderne pour la purification de l'eau poss\u00e8de \u00e9galement des caract\u00e9ristiques d'adsorption, elle est donc utilis\u00e9e comme d\u00e9shydratant pour les gaz et les liquides, comme adsorbant pour la purification des gaz, comme agent de d\u00e9fluoration pour l'eau potable et comme agent d'\u00e9limination des couleurs et des odeurs pour les eaux us\u00e9es industrielles.<\/p>\n

3. la classification des billes d'alumine activ\u00e9es<\/strong><\/p>\n

Les billes d'alumine activ\u00e9e sont actuellement produites principalement dans quatre cat\u00e9gories : les d\u00e9shydratants, les adsorbants, les agents de d\u00e9fluoration et les catalyseurs, en fonction de leur utilisation. \u00c0 l'heure actuelle, elles sont principalement utilis\u00e9es comme d\u00e9shydratants adsorbants et agents de d\u00e9fluoration. Ils sont notamment utilis\u00e9s pour le peroxyde d'hydrog\u00e8ne, l'adsorption par variation de pression, le s\u00e9chage par compression d'air, la d\u00e9shydratation par s\u00e9paration des gaz, le s\u00e9chage de l'air des instruments, la s\u00e9paration de l'air, la fabrication de gaz, la d\u00e9fluoration et la d\u00e9fluorisation du traitement de l'eau, la catalyse chimique, l'industrie p\u00e9trochimique, la m\u00e9decine, le raffinage du p\u00e9trole, l'industrie des engrais, etc.<\/p>","protected":false},"excerpt":{"rendered":"
