1. Introduction<\/strong><\/h2>\n\n\n\n

La poudre de silice sph\u00e9rique est une sorte de poudre de silice avec des particules sph\u00e9riques, son composant principal est le dioxyde de silicium. Avec des caract\u00e9ristiques de bonne di\u00e9lectrique<\/a> Propri\u00e9t\u00e9, bonne conductivit\u00e9 thermique et faible coefficient de dilatation, la poudre de silice sph\u00e9rique est largement utilis\u00e9e dans les domaines de l'emballage d'appareils \u00e9lectroniques, de l'a\u00e9rospatiale, des rev\u00eatements et des cosm\u00e9tiques, etc.<\/p>\n\n\n\n

2. M\u00e9thodes de production<\/strong><\/h2>\n\n\n\n

Selon les changements chimiques qui se produisent, les m\u00e9thodes de production de poudre de silice sph\u00e9rique peuvent \u00eatre divis\u00e9es en m\u00e9thodes physiques et m\u00e9thodes chimiques. Les m\u00e9thodes physiques comprennent : la m\u00e9thode de broyage m\u00e9canique, la m\u00e9thode de pulv\u00e9risation, la sph\u00e9ro\u00efdisation \u00e0 la flamme, la m\u00e9thode au plasma et la m\u00e9thode de sph\u00e9ro\u00efdisation par calcination \u00e0 haute temp\u00e9rature, etc. Les m\u00e9thodes chimiques comprennent principalement : la m\u00e9thode en phase gazeuse, la m\u00e9thode de pr\u00e9cipitation, la m\u00e9thode hydrothermale, la m\u00e9thode sol-gel et la m\u00e9thode de micro\u00e9mulsion, etc. <\/p>\n\n\n\n

Ensuite, nous parlerons sp\u00e9cifiquement de certaines des principales m\u00e9thodes.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

2.1. M\u00e9thode de broyage m\u00e9canique<\/strong><\/h3>\n\n\n\n

En utilisant un \u00e9quipement de concassage professionnel et un \u00e9quipement de criblage auxiliaire, il est possible d'obtenir de la poudre de silice sph\u00e9rique. Cette m\u00e9thode convient \u00e0 la production de poudre de silice ultrafine.<\/p>\n\n\n\n

2.2. M\u00e9thode de pulv\u00e9risation<\/strong><\/h3>\n\n\n\n

Dissoudre la source de silicium (telle que silicate<\/a>) dans un solvant appropri\u00e9 pour former une solution uniforme. Ensuite, la solution est pulv\u00e9ris\u00e9e \u00e0 l'aide d'un dispositif de pulv\u00e9risation et les gouttelettes sont rapidement pyrolys\u00e9es \u00e0 haute temp\u00e9rature. On obtient enfin de la poudre de silice.<\/p>\n\n\n\n

2.3. Sph\u00e9ro\u00efdisation par flamme<\/strong><\/h3>\n\n\n\n

Cette m\u00e9thode n\u00e9cessite un pr\u00e9traitement de concassage, de criblage et de purification sur du sable de quartz de haute puret\u00e9. Ensuite, la poudre de quartz est envoy\u00e9e dans un champ \u00e0 haute temp\u00e9rature g\u00e9n\u00e9r\u00e9 par du gaz-oxyg\u00e8ne pour une fusion \u00e0 haute temp\u00e9rature. Ensuite, la poudre fondue est refroidie et on obtient enfin une poudre de silice sph\u00e9rique de haute puret\u00e9.<\/p>\n\n\n\n

2.4. m\u00e9thode plasma<\/strong><\/h3>\n\n\n\n

La m\u00e9thode utilise de la poudre de silice angulaire comme mati\u00e8re premi\u00e8re. Tout d'abord, la poudre de silice angulaire est trait\u00e9e par broyage, tamisage et purification, puis elle est fondue instantan\u00e9ment \u00e0 haute temp\u00e9rature \u00e0 l'aide d'ac\u00e9tyl\u00e8ne ou de gaz naturel comme sources de chaleur, puis refroidie rapidement en billes, pour enfin obtenir une poudre de silice de haute puret\u00e9 et aux particules uniformes.<\/p>\n\n\n\n

3. R\u00e9sum\u00e9<\/strong><\/h2>\n\n\n\n

Avec l'am\u00e9lioration continue des m\u00e9thodes de production, l'application de la poudre de silice sph\u00e9rique sera encore \u00e9largie. Dans les applications pratiques, sa production n\u00e9cessite g\u00e9n\u00e9ralement des proc\u00e9dures de concassage, de criblage, de purification et de classification, etc. Elle n\u00e9cessite un contr\u00f4le strict de la formule et de l'\u00e9quipement pour garantir la qualit\u00e9 et les performances des produits finis.<\/p>\n\n\n\n
