Le liquide transparent de nanoalumine XZ-LY101 est incolore et transparent. Le liquide transparent de dispersion de nano-alumine utilise 5 \u00e0 10 nanom\u00e8tres d'alumine. L'alumine est une sorte d'alumine cribl\u00e9e par un traitement en profondeur de la nano-alumine. Elle est ajout\u00e9e \u00e0 diverses r\u00e9sines acryliques, r\u00e9sines de polyur\u00e9thane et r\u00e9sines \u00e9poxy. Dans le liquide \u00e0 base d'eau de la r\u00e9sine de m\u00e9lamine, de l'\u00e9mulsion acrylique de silicone et d'autres r\u00e9sines, la quantit\u00e9 ajout\u00e9e est de 5% \u00e0 10%, ce qui peut augmenter la duret\u00e9 de la r\u00e9sine, la duret\u00e9 peut atteindre 6-8H, et elle est compl\u00e8tement transparente. Le liquide de nanoalumine peut \u00eatre \u00e0 base d'eau ou d'huile. Tout solvant peut \u00eatre utilis\u00e9 pour toutes sortes de mat\u00e9riaux de rev\u00eatement en verre, de pierres pr\u00e9cieuses, d'instruments de pr\u00e9cision, etc.<\/p>\n<p>1. L'alumine est le composant principal de la bauxite. Industriellement, la bauxite est purifi\u00e9e en alumine par le proc\u00e9d\u00e9 Bayer, puis convertie en aluminium m\u00e9tal par le proc\u00e9d\u00e9 Hall-Heroult.<\/p>\n<p>2. L'alumine est la raison pour laquelle l'aluminium m\u00e9tallique ne se corrode pas facilement \u00e0 l'air. L'aluminium m\u00e9tallique pur r\u00e9agit facilement avec l'oxyg\u00e8ne de l'air pour former une fine pellicule d'oxyde d'aluminium qui recouvre la surface de l'aluminium expos\u00e9e \u00e0 l'air. Ce film d'oxyde d'aluminium peut emp\u00eacher l'aluminium de s'oxyder davantage. L'\u00e9paisseur et les propri\u00e9t\u00e9s de ce film d'oxyde peuvent \u00eatre am\u00e9lior\u00e9es par un processus appel\u00e9 traitement anodique (protection anodique contre la corrosion).<\/p>\n<p>3. L'aluminium est un bon conducteur d'\u00e9lectricit\u00e9 et de chaleur. La forme cristalline de l'\u00e9meri d'aluminium convient aux mat\u00e9riaux abrasifs et aux outils de coupe en raison de sa grande duret\u00e9.<\/p>\n<p>4. La poudre d'alumine est souvent utilis\u00e9e comme support pour la chromatographie.<\/p>","protected":false},"excerpt":{"rendered":"<p>The production process of alumina powder is getting higher and higher, and alumina powder of less than 1 micron can be produced.
