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

La silice est une poudre de dioxyde de silicium amorphe (SiO\u2082) synth\u00e9tis\u00e9e artificiellement, de formule chimique SiO\u2082\u00b7nH\u2082O. C'est un mat\u00e9riau fonctionnel important, largement utilis\u00e9 dans les domaines du caoutchouc, des rev\u00eatements, des produits pharmaceutiques, etc. Les performances de la silice sont \u00e9troitement li\u00e9es \u00e0 des param\u00e8tres cl\u00e9s tels que la distribution granulom\u00e9trique (PSD) et la surface sp\u00e9cifique (BET), ce qui rend une technologie de classification efficace essentielle \u00e0 l'optimisation de ses applications industrielles. Le classificateur \u00e0 air de Qingdao Epic Powder Machinery Co., Ltd. permet une classification pr\u00e9cise de la silice sans alt\u00e9rer la structure des particules, am\u00e9liorant ainsi l'uniformit\u00e9 et les performances d'application du produit.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Avantages du classificateur \u00e0 air pour la classification de la silice<\/strong><\/h2>\n\n\n\n

Le classificateur \u00e0 air est un \u00e9quipement qui utilise plusieurs forces telles que force centrifuge<\/a>, force d'inertie, gravit\u00e9, etc. pour s\u00e9parer des particules de diff\u00e9rentes tailles. Ses principaux avantages se manifestent par\u00a0:<\/p>\n\n\n\n

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

<\/p>\n\n\n\n

\u2013 Haute pr\u00e9cision de classification<\/strong><\/h3>\n\n\n\n

\u00a0<\/strong>Il peut s\u00e9parer avec pr\u00e9cision les particules de silice de diff\u00e9rentes tailles de particules pour obtenir des produits avec une distribution granulom\u00e9trique \u00e9troite et une bonne uniformit\u00e9.<\/p>\n\n\n\n

\u2013 Haute efficacit\u00e9 de production<\/strong><\/h3>\n\n\n\n

\u00a0En utilisant un flux d'air \u00e0 grande vitesse, une grande quantit\u00e9 de silice peut \u00eatre rapidement class\u00e9e, am\u00e9liorant ainsi l'efficacit\u00e9 de la production et r\u00e9pondant aux besoins de la production industrielle.<\/p>\n\n\n\n

\u2013 Bonne performance environnementale<\/strong><\/h3>\n\n\n\n

L'ensemble du processus de classement est r\u00e9alis\u00e9 dans un syst\u00e8me ferm\u00e9, \u00e9vitant les fuites de poussi\u00e8re et la pollution, et r\u00e9pondant aux exigences de protection de l'environnement.<\/p>\n\n\n\n

\u2013 Facile \u00e0 utiliser<\/strong><\/h3>\n\n\n\n

Dot\u00e9 d'un haut degr\u00e9 d'automatisation et d'une grande simplicit\u00e9 d'utilisation, l'\u00e9quipement peut fonctionner automatiquement gr\u00e2ce \u00e0 des param\u00e8tres d\u00e9finis, r\u00e9duisant ainsi la charge de travail li\u00e9e aux op\u00e9rations manuelles.<\/p>\n\n\n\n

Effet de classification du classificateur \u00e0 air sur la silice<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

1 Contr\u00f4le pr\u00e9cis de la granulom\u00e9trie <\/strong><\/h3>\n\n\n\n

Silice ordinaire (D50 : 10 \u2013 50 \u03bcm) \u2192 Une poudre fine avec D97 < 10 \u03bcm peut \u00eatre s\u00e9par\u00e9e, et m\u00eame une qualit\u00e9 ultra-fine avec D50 : 1 \u2013 5 \u03bcm peut \u00eatre obtenue.<\/p>\n\n\n\n

Agr\u00e9gats de silice \u00e0 l'\u00e9chelle nanom\u00e9trique \u2192 Brisent efficacement les agr\u00e9gats et s\u00e9parent les particules entre 100 nanom\u00e8tres et 1 micron.<\/p>\n\n\n\n

\u2461 Optimisation de la surface sp\u00e9cifique<\/strong><\/h3>\n\n\n\n

La surface sp\u00e9cifique de la silice non class\u00e9e peut fluctuer de mani\u00e8re significative (par exemple, 150 \u00e0 300 m\u00b2\/g), tandis qu'apr\u00e8s classification :<\/p>\n\n\n\n

Partie \u00e0 grosses particules (surface sp\u00e9cifique \u2193, renforcement r\u00e9duit, convient aux charges ordinaires).<\/p>\n\n\n\n

Partie \u00e0 particules fines (surface sp\u00e9cifique\u2191, adapt\u00e9e au caoutchouc et aux rev\u00eatements haut de gamme).<\/p>\n\n\n\n

\u2462 Am\u00e9lioration de la coh\u00e9rence du produit<\/strong><\/h3>\n\n\n\n

Apr\u00e8s classification, l'\u00e9tendue de la distribution granulom\u00e9trique (valeur d'\u00e9tendue) peut \u00eatre consid\u00e9rablement r\u00e9duite. Par exemple\u00a0:<\/p>\n\n\n\n

Avant classification : Span (D90-D10)\/D50 \u2248 2,5 (distribution large). Apr\u00e8s classification : Span < 1,5 (distribution \u00e9troite).<\/p>\n\n\n\n

Cas d'application r\u00e9els d'Epic Powder<\/strong><\/h2>\n\n\n\n

Cas 1 : <\/strong>L'un de nos clients a besoin d'une classification de la silice pour pneus<\/a>, pour am\u00e9liorer le renforcement et r\u00e9duire la r\u00e9sistance au roulement des pneus.<\/p>\n\n\n\n

Notre solution : En adoptant une classification de l'air \u00e0 plusieurs \u00e9tapes, notre client a obtenu une poudre fine avec D50 : 5~10\u03bcm, la surface sp\u00e9cifique a augment\u00e9 de 15% et la r\u00e9sistance \u00e0 l'usure du pneu a \u00e9t\u00e9 am\u00e9lior\u00e9e.<\/p>\n\n\n\n

Cas 2<\/strong>:Un autre client souhaite pr\u00e9parer de la silice de qualit\u00e9 pharmaceutique, avec D90<10\u03bcm, et elle doit r\u00e9pondre aux normes de la pharmacop\u00e9e.<\/p>\n\n\n\n

Notre solution : Classification de l'air de haute pr\u00e9cision + modification de surface.<\/p>\n\n\n\n

Le classificateur \u00e0 air permet de classer avec pr\u00e9cision la silice en diff\u00e9rentes granulom\u00e9tries afin de r\u00e9pondre aux exigences strictes de diff\u00e9rents domaines d'application. \u00c0 l'avenir, gr\u00e2ce au d\u00e9veloppement de la technologie de classification, l'application du classificateur \u00e0 air \u00e0 la silice sera encore \u00e9largie.<\/p>\n\n\n\n
