Une fois modifi\u00e9, le carbonate de calcium passe d&#039;une charge traditionnelle \u00e0 un additif multifonctionnel aux applications plus vari\u00e9es et \u00e0 la demande accrue.<\/p>\n\n\n\n<p><strong>Am\u00e9lioration de la dispersion du carbonate de calcium<\/strong><br>La modification de surface permet l&#039;adsorption s\u00e9lective du modificateur sur la surface du carbonate de calcium, lui conf\u00e9rant des propri\u00e9t\u00e9s charg\u00e9es. La r\u00e9pulsion entre charges de m\u00eame signe emp\u00eache l&#039;agglom\u00e9ration, assurant ainsi une meilleure dispersion du mat\u00e9riau.<\/p>\n\n\n\n<p><strong>Am\u00e9lioration de la compatibilit\u00e9 avec d&#039;autres mat\u00e9riaux<\/strong><br>La modification de surface accro\u00eet la compatibilit\u00e9 interfaciale entre le carbonate de calcium et d&#039;autres mat\u00e9riaux, tels que le caoutchouc ou les plastiques.
