Elle pr\u00e9sente les caract\u00e9ristiques suivantes : r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, r\u00e9sistance \u00e0 la corrosion et propri\u00e9t\u00e9s stables. Le processus de production de la poudre d'alumine devenant plus \u00e9lev\u00e9, il est techniquement possible de produire une poudre d'alumine inf\u00e9rieure \u00e0 1\u03bcm. Il est largement utilis\u00e9 dans diverses r\u00e9sines acryliques, r\u00e9sines de polyur\u00e9thane, r\u00e9sines \u00e9poxy et autres additifs. Il peut \u00e9galement s'agir de solvants \u00e0 base d'eau ou d'huile. Elle peut \u00eatre enduite sur des mat\u00e9riaux de rev\u00eatement en verre, des pierres pr\u00e9cieuses, des mat\u00e9riaux pour instruments de pr\u00e9cision, etc. Elle est couramment utilis\u00e9e pour les r\u00e9actifs d'analyse, la d\u00e9shydratation de solvants organiques, les adsorbants, les catalyseurs de r\u00e9actions organiques, les abrasifs, les agents de polissage, les mati\u00e8res premi\u00e8res pour la fonte de l'aluminium et les mat\u00e9riaux r\u00e9fractaires. La poudre d'alumine est-elle donc toxique ?<\/p>\n<p>Pour savoir si la poudre d'alumine activ\u00e9e est elle-m\u00eame toxique, il faut d'abord comprendre ses propri\u00e9t\u00e9s, son processus de production et les propri\u00e9t\u00e9s de ses mati\u00e8res premi\u00e8res.<\/p>\n<p><a href=\"\/fr\/produit\/poudre-de-ceramique-dalumine\/\" target=\"_blank\" rel=\"noopener\">Poudre d'alumine activ\u00e9e<\/a> (Al2O3) est principalement produit par s\u00e9chage, broyage et torr\u00e9faction de l'hydroxyde d'aluminium industriel. Aucun additif ou composant chimique n'est ajout\u00e9 au cours du processus de production. L'hydroxyde d'aluminium, dont la formule chimique est Al(OH)3, est l'hydroxyde d'aluminium. L'hydroxyde d'aluminium peut r\u00e9agir avec l'acide pour former du sel et de l'eau, et il peut \u00e9galement r\u00e9agir avec une base forte pour former du sel et de l'eau. Il s'agit donc d'un hydroxyde amphot\u00e8re et d'une poudre non toxique et inodore.<\/p>\n<p>La toxicit\u00e9 de la poudre d'alumine activ\u00e9e est donc la suivante :<\/p>\n<p>Ingestion : Faible risque, peut causer la maladie d'Alzheimer et nuire \u00e0 l'intelligence des enfants. Inhalation : Peut provoquer une irritation ou des l\u00e9sions pulmonaires. Peau : Faible risque. Yeux : faible risque.<\/p>","protected":false},"excerpt":{"rendered":"<p>Alumina powder is the main raw material for abrasives such as white corundum sand.
