Crit\u00e8res de classification<\/strong><\/h2>\n\n\n\n

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

1. Selon la taille des particules<\/strong><\/h3>\n\n\n\n

Il s'agit de la norme de classification la plus couramment utilis\u00e9e, et elle est principalement bas\u00e9e sur le diam\u00e8tre des particules (microm\u00e8tre ou nanom\u00e8tre) :<\/p>\n\n\n\n

Utilisations : Rev\u00eatements haut de gamme, produits d'\u00e9tanch\u00e9it\u00e9, produits pharmaceutiques excipients<\/a>, etc.<\/p>\n\n\n\n

\u2013 Carbonate de calcium nano<\/strong><\/h4>\n\n\n\n

Taille des particules : <100 nm<\/p>\n\n\n\n

Caract\u00e9ristiques : Il n\u00e9cessite un processus sp\u00e9cial (tel que la carbonisation), avec des caract\u00e9ristiques de renforcement et de durcissement.<\/p>\n\n\n\n

Utilisations : caoutchouc haut de gamme, plastique, encre, cosm\u00e9tiques (comme la cr\u00e8me solaire), etc.<\/p>\n\n\n\n

Concernant la m\u00e9thode de classification du carbonate de calcium selon la granulom\u00e9trie, approfondissons la classification de la poudre de carbonate de calcium. Afin de r\u00e9pondre aux diff\u00e9rentes exigences granulom\u00e9triques, la poudre de carbonate de calcium doit \u00eatre class\u00e9e selon diff\u00e9rentes granulom\u00e9tries. Classeur \u00e0 air produit par <\/em>Qingdao Epic Powder Machinery Co., Ltd.<\/a> <\/em><\/strong><\/em><\/strong>Con\u00e7u et fabriqu\u00e9 par notre consultant allemand, ce classificateur \u00e0 air est particuli\u00e8rement adapt\u00e9 au traitement de classification des min\u00e9raux non m\u00e9talliques, dont le carbonate de calcium, et offre une efficacit\u00e9 et une pr\u00e9cision de classification \u00e9lev\u00e9es. Il se d\u00e9cline en cinq types\u00a0: HTS<\/a>, CCI<\/a>, CTC<\/a>, MBS<\/a>, TDC<\/a>.

Conclusion<\/strong><\/h2>\n\n\n\n

La classification du carbonate de calcium est un syst\u00e8me multidimensionnel, chaque m\u00e9thode refl\u00e9tant ses caract\u00e9ristiques physiques, chimiques et fonctionnelles uniques. Ces caract\u00e9ristiques lui permettent d'\u00eatre largement utilis\u00e9 dans divers secteurs, allant des mat\u00e9riaux de construction de base aux industries pharmaceutiques et cosm\u00e9tiques de haute technologie, jouant un r\u00f4le important dans l'industrie moderne et la vie quotidienne.<\/p>","protected":false},"excerpt":{"rendered":"
