Le carbonate de calcium l\u00e9ger ordinaire pr\u00e9sente souvent une forme fusiforme. Dans le PVC, il provoque des contraintes internes et un blanchiment des films plastiques. Le carbonate de calcium ultrafin doit \u00eatre produit avec diff\u00e9rentes formes cristallines selon l&#039;application.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Plastiques<\/h3>\n\n\n\n<p>Pour les plastiques, les cristaux cubiques ou sph\u00e9riques sont id\u00e9aux. Leur structure est simple, leur absorption d&#039;huile est moindre et leur volume de remplissage est r\u00e9duit. Le carbonate de calcium ultrafin, d&#039;une granulom\u00e9trie de 0,072 \u03bcm, am\u00e9liore les propri\u00e9t\u00e9s du PVC. Il am\u00e9liore le liss\u00e9, la brillance et l&#039;isolation \u00e9lectrique de la surface. Dans les compos\u00e9s de c\u00e2bles souples, m\u00eame en doublant le taux de remplissage, les performances restent conformes aux normes nationales. Dans les films plastiques, le blanchiment est r\u00e9duit et l&#039;allongement \u00e0 basse temp\u00e9rature est am\u00e9lior\u00e9. Dans les plastiques rigides comme les fen\u00eatres et les profil\u00e9s, la r\u00e9sistance aux chocs est renforc\u00e9e. La r\u00e9sistance aux chocs entaill\u00e9s peut atteindre 49,1 kJ\/m\u00b2.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Caoutchouc<\/h3>\n\n\n\n<p>Pour le caoutchouc, le carbonate de calcium ultrafin en cha\u00eene offre le meilleur renforcement. Les structures en cha\u00eene sont constitu\u00e9es de nombreuses particules li\u00e9es dans une m\u00eame direction. Elles pr\u00e9sentent un r\u00e9seau spatial tridimensionnel et une excellente dispersion. Lors du m\u00e9lange, les cha\u00eenes se brisent pour former des surfaces actives. Celles-ci se lient fortement aux cha\u00eenes de caoutchouc, am\u00e9liorant ainsi consid\u00e9rablement le renforcement. L&#039;ordre de force du renforcement est le suivant\u00a0: en forme de cha\u00eene &gt; en forme d&#039;aiguille &gt; sph\u00e9rique &gt; cubique.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Encres<\/h3>\n\n\n\n<p>Pour les encres, les cristaux cubiques sont privil\u00e9gi\u00e9s. Ils apportent brillance, transparence et fluidit\u00e9 aux encres \u00e0 base de r\u00e9sine. Pour le couchage du papier, on utilise souvent du carbonate de calcium pr\u00e9cipit\u00e9. Sa granulom\u00e9trie est de 0,1 \u00e0 1 \u03bcm, mais n&#039;est pas ultrafine. Cependant, la forme cristalline reste importante. Les formes lamellaires et cubiques sont id\u00e9ales pour l&#039;opacit\u00e9, la blancheur et l&#039;absorption de l&#039;encre.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Valeur d&#039;absorption d&#039;huile<\/h2>\n\n\n\n<p>L&#039;absorption d&#039;huile est cruciale pour les plastiques, les rev\u00eatements et les encres. Une absorption d&#039;huile \u00e9lev\u00e9e augmente la consommation de plastifiants dans les plastiques. Elle augmente \u00e9galement la viscosit\u00e9 des encres et des rev\u00eatements. Par cons\u00e9quent, une valeur d&#039;absorption d&#039;huile plus faible est pr\u00e9f\u00e9rable.<\/p>\n\n\n\n<p>La granulom\u00e9trie et la dispersion influencent fortement l&#039;absorption d&#039;huile. Une mauvaise dispersion entra\u00eene une agglom\u00e9ration secondaire et une faible surface sp\u00e9cifique. Dans ce cas, m\u00eame avec une faible absorption d&#039;huile, le produit n&#039;est pas efficace. Par cons\u00e9quent, le carbonate de calcium ultrafin doit d&#039;abord garantir une granulom\u00e9trie fine, une dispersion \u00e9lev\u00e9e et une grande surface sp\u00e9cifique. De ce fait, r\u00e9duire l&#039;absorption d&#039;huile pr\u00e9sente un r\u00e9el int\u00e9r\u00eat.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Contenu principal<\/h2>\n\n\n\n<p>Le carbonate de calcium ultrafin contient principalement du CaO. Dans des limites raisonnables, des limites strictes sont superflues. En tant que charge fonctionnelle, les propri\u00e9t\u00e9s physiques sont plus importantes que la composition chimique. Lors du traitement, des dispersants, des agents de contr\u00f4le et des modificateurs de surface sont souvent ajout\u00e9s. Ces additifs am\u00e9liorent la dispersion et l&#039;activation, sans nuire aux performances du produit. Cependant, les impuret\u00e9s nocives telles que le fer et le mangan\u00e8se doivent \u00eatre strictement contr\u00f4l\u00e9es. Elles alt\u00e8rent la couleur, acc\u00e9l\u00e8rent la d\u00e9gradation de la r\u00e9sine et r\u00e9duisent sa dur\u00e9e de vie. D&#039;autres impuret\u00e9s telles que le silicium, l&#039;aluminium et le magn\u00e9sium peuvent r\u00e9duire la blancheur et compliquer la production. Le choix des mati\u00e8res premi\u00e8res doit donc \u00eatre rigoureusement contr\u00f4l\u00e9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Ligne de production de broyeurs \u00e0 boulets et de classificateurs pour carbonate de calcium, y compris rev\u00eatement de surface en poudre\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/2EAsJYcLgB8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Le d\u00e9veloppement du carbonate de calcium superfin doit privil\u00e9gier la sp\u00e9cialisation, la diversification et la fonctionnalisation.
