Le corindon blanc est l'un des abrasifs les plus couramment utilis\u00e9s sur le march\u00e9. Sa composition chimique principale est AL2O3. Selon la teneur en poudre d'alumine<\/a>Il peut \u00eatre divis\u00e9 en plusieurs cat\u00e9gories, telles que la premi\u00e8re et la deuxi\u00e8me cat\u00e9gorie. Ces derni\u00e8res ann\u00e9es, les outils en corindon blanc sont devenus des mat\u00e9riaux durs et cassants. La promotion dans le domaine du meulage de semi-pr\u00e9cision et de pr\u00e9cision convient \u00e0 l'embellissement de la surface de divers produits haut de gamme, de l'artisanat ou de la quincaillerie. Apr\u00e8s le sablage, la surface est blanche sans aucune impuret\u00e9, ce qui \u00e9limine les probl\u00e8mes de nettoyage. Le corindon blanc de taille fine peut \u00eatre utilis\u00e9 comme premier produit de polissage et de meulage, et le sable de corindon blanc est un produit abrasif tr\u00e8s important dans l'industrie du polissage et du meulage. La duret\u00e9 du sable de corindon blanc est sup\u00e9rieure \u00e0 celle du corindon brun, avec une capacit\u00e9 de coupe plus forte, une bonne stabilit\u00e9 chimique et de tr\u00e8s bonnes performances d'isolation. Il est principalement utilis\u00e9 dans la production d'outils abrasifs fixes, d'outils abrasifs appliqu\u00e9s, dans le sablage humide et le sablage \u00e0 sec, dans les op\u00e9rations de meulage et de polissage ultrafines dans l'industrie \u00e9lectronique et dans les mat\u00e9riaux r\u00e9fractaires de haute qualit\u00e9. Parall\u00e8lement, la poudre de sable blanc corindon WA peut \u00e9galement \u00eatre utilis\u00e9e dans les domaines du contact. les isolateurs et le moulage de pr\u00e9cision. En tant que mati\u00e8re premi\u00e8re principale du corindon blanc<\/a>La qualit\u00e9 de la bauxite a un impact significatif sur la consommation d'\u00e9nergie de la fusion du corindon blanc.<\/p>\n

La bauxite est \u00e9galement appel\u00e9e bauxite ou bauxite. Le principal composant est poudre d'alumine<\/a>. Il s'agit d'une sorte de min\u00e9ral terreux, blanc ou blanc cass\u00e9, jaune brun\u00e2tre ou rouge clair en raison de sa teneur en fer. La poudre d'alumine est un corindon brun. La s\u00e9lection des sources de mati\u00e8res premi\u00e8res et le contr\u00f4le de la qualit\u00e9 des mati\u00e8res premi\u00e8res sont donc cruciaux, car la s\u00e9lection des mati\u00e8res premi\u00e8res d\u00e9termine dans une certaine mesure la qualit\u00e9, la performance et le champ d'application de ses produits. La principale mati\u00e8re premi\u00e8re pour la fonte du corindon brun et du corindon blanc est la bauxite l\u00e9g\u00e8re. Cette derni\u00e8re est l\u00e9g\u00e8rement grill\u00e9e \u00e0 1000\uff5e1200\u2103 pour am\u00e9liorer sa qualit\u00e9 et r\u00e9duire la consommation d'\u00e9nergie. Une exp\u00e9rience a permis de comparer le processus entre la bauxite grill\u00e9e et la bauxite non grill\u00e9e, et le r\u00e9sultat est qu'il est possible de r\u00e9duire la consommation d'\u00e9nergie H 5 par unit\u00e9 de 14% \u00e0 18% apr\u00e8s le grillage. La bauxite chinoise est une bauxite \u00e0 haute teneur en silicium et \u00e0 faible teneur en fer. Plus le rapport aluminium-silicium est \u00e9lev\u00e9, plus la qualit\u00e9 de la bauxite est \u00e9lev\u00e9e. Les indicateurs techniques et \u00e9conomiques de la fusion du corindon brun d\u00e9pendent largement de la qualit\u00e9 de la principale mati\u00e8re premi\u00e8re, la bauxite, \u00e0 savoir Plus la teneur est \u00e9lev\u00e9e, meilleurs sont les indicateurs techniques et \u00e9conomiques de l'alumine fondue brune et de l'alumine fondue blanche. L'alumine brune fondue et l'alumine blanche fondue sont des produits \u00e0 forte consommation d'\u00e9nergie. Les \u00e9conomies d'\u00e9nergie sont particuli\u00e8rement importantes pour la production d'alumine brune fondue et d'alumine blanche fondue. La qualit\u00e9 de la bauxite d\u00e9termine le niveau de consommation d'\u00e9nergie.<\/p>\n

Plus la qualit\u00e9 de la bauxite est \u00e9lev\u00e9e, plus le processus de fusion est facile \u00e0 ma\u00eetriser, l'\u00e9tat du four est stable, le rendement horaire est \u00e9lev\u00e9, la consommation d'\u00e9nergie unitaire est faible et la consommation de mati\u00e8res premi\u00e8res est \u00e9galement moindre ; plus la teneur en impuret\u00e9s d'alumine SiO2 est \u00e9lev\u00e9e, plus l'\u00e9tat du four pendant la fusion est bon. La complexit\u00e9, la consommation d'\u00e9nergie unitaire \u00e9lev\u00e9e et le faible rendement peuvent m\u00eame entra\u00eener des difficult\u00e9s dans la s\u00e9paration magn\u00e9tique du traitement du corindon. On peut en d\u00e9duire qu'avec le manque de ressources en bauxite de haute qualit\u00e9 en Chine et la diminution continue des teneurs en bauxite, non seulement le co\u00fbt et la consommation d'\u00e9nergie de la fusion du corindon brun augmenteront, mais le processus de fusion sera \u00e9galement plus difficile \u00e0 contr\u00f4ler, et les indicateurs \u00e9conomiques des produits se sont d\u00e9t\u00e9rior\u00e9s, la qualit\u00e9 des produits est instable, et la comp\u00e9titivit\u00e9 du march\u00e9 est vou\u00e9e \u00e0 diminuer.<\/p>","protected":false},"excerpt":{"rendered":"
