Pour les sacs tiss\u00e9s, le carbonate de calcium est pr\u00e9f\u00e9rable, avec un ajout sup\u00e9rieur \u00e0 30%. Il est important de surveiller la temp\u00e9rature pendant le traitement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Utilisations courantes du talc et du carbonate de calcium comme charges<\/h2>\n\n\n\n<p>L&#039;utilisation de ces charges vise principalement \u00e0 accro\u00eetre la stabilit\u00e9 dimensionnelle (c&#039;est-\u00e0-dire \u00e0 r\u00e9duire le retrait), \u00e0 am\u00e9liorer la rigidit\u00e9 et la r\u00e9sistance \u00e0 la chaleur du mat\u00e9riau et \u00e0 r\u00e9duire les co\u00fbts. Cependant, leur utilisation pr\u00e9sente \u00e9galement des inconv\u00e9nients, notamment une augmentation de la densit\u00e9, une diminution potentielle de la r\u00e9sistance aux chocs en cas d&#039;utilisation incorrecte et une diminution de la brillance du mat\u00e9riau.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Taille et s\u00e9lection des particules<\/h2>\n\n\n\n<p>Le talc, comme le carbonate de calcium, est disponible en diff\u00e9rentes granulom\u00e9tries, g\u00e9n\u00e9ralement de 300 mesh, 600 mesh, 800 mesh, 1250 mesh et 2500 mesh, avec des options encore plus fines. Pour les applications plastiques, les talcs de 800 mesh et 1250 mesh offrent souvent le meilleur rapport performance\/co\u00fbt. Le prix du talc fluctue, mais son prix peut g\u00e9n\u00e9ralement \u00eatre fix\u00e9 en fonction du nombre de mesh. Par exemple, le talc de 800 mesh co\u00fbte g\u00e9n\u00e9ralement entre 700 et 850 yuans, tandis que celui de 1250 mesh varie entre 1000 et 1280 yuans.
