Title (EN) PRECIPITATED CALCIUM CARBONATE WITH IMPROVED RESISTANCE TO STRUCTURAL BREAKDOWN
(FR) CARBONATE DE CALCIUM PRÉCIPITÉ PRÉSENTANT UNE RÉSISTANCE AMÉLIORÉE À LA DÉCOMPOSITION STRUCTURALE
Abstract:
(EN) The present invention is directed to a process for producing precipitated calcium carbonate with improved resistance to structural breakdown, wherein the milk of lime is carbonated in the presence of at least one gas other than carbon dioxide, or 5the carbonation is carried out in the presence of a static gas bubble comminution unit as well as to precipitated calcium carbonate obtained by such a process.
(FR) La présente invention concerne un procédé de production de carbonate de calcium précipité présentant une résistance améliorée à la décomposition structurale, dans lequel le lait de chaux est carbonaté en présence d'au moins un gaz autre que le dioxyde de carbone, ou la carbonatation est effectuée en présence d'une unité de broyage à barbotage de gaz statique, ainsi que le carbonate de calcium précipité obtenu par un tel procédé.
