Process for loading fibers with calcium carbonate |
摘要 |
During the chemical process of loading with calcium carbonate fibers contained in a pulp suspension, a medium containing calcium oxide or calcium hydroxide is added to the pulp suspension. This treated pulp suspension is charged in at least one reactor with pure carbon dioxide (or a medium containing carbon dioxide), which, during the progression of the reaction, converts at least a significant portion of the starting materials (calcium oxide and/or calcium hydroxide and carbon dioxide) into the reaction products, calcium carbonate and water. This reaction is accomplished by properly controlling the pulp suspension's pH.
