摘要： The invention relates to papermaking processes wherein calcium carbonate is included in a pulp suspension. The dissolution of the calcium carbonate in the papermaking system is prevented or substantially retarded by the introduction of carbon dioxide to said pulp suspension in connection with subjecting said calcium carbonate in said papermaking system to pH conditions of about 8 or lower. The invention also provides processes for the production of paper or board in papermaking systems wherein solid calcium carbonate is present as a filler and/or pigment.

摘要： The present invention relates to an acid-stabilized calcium carbonate slurry having a pH of less than 7, preferably between about 6 and about 7, containing water, calcium carbonate, preferably precipitated calcium carbonate, and an acid-stabilizer of a water soluble calcium salt, a weak acid, a chelating agent, a weak acid capable of chelating calcium ion, or a mixture thereof. The acid-stabilizer is present in an amount sufficient to provide an aqueous calcium carbonate slurry having an increased calcium ion concentration and an acidic pH. In a typical acid-stabilized calcium carbonate slurry of the invention, the acid-stabilizer is present in an amount sufficient to provide a calcium ion concentration of about 1 millimolar to about 5 molar, preferably from about 1 to about 120 millimolar. The invention also relates to a method of making the acid-stabilized calcium carbonate slurry of the invention, to a method of forming a filled paper, that includes the step of adding the acid-stabilized calcium carbonate slurry of the invention to a papermaking pulp in a process for making acid paper, and to a filled paper produced according to the method of the invention.

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.

摘要： A fiber loading apparatus continuously loads fibers in a fiber suspension with a chemical compound. A pulper has an inner chamber, a shear imparting device within the inner chamber, an inlet and an outlet. The pulper inlet receives a fiber suspension at a consistency of between 20 and 30%. The shear imparting device, which may be configured as a rotor, imparts high shear forces to the fiber suspension. A fluffer includes an inner chamber, an inlet and an outlet. The fluffer inlet is connected with the pulper outlet. A reactor includes an inner chamber, an inlet and an outlet. The reactor inlet is connected with the fluffer outlet. A gas supply is connected with the fluffer inner chamber and/or reactor inner chamber. The gas supply supplies and pressurizes the fluffer inner chamber and/or reactor inner chamber with a gas, such as carbon dioxide or ozone, acting as a reactant for the chemical compound to be loaded into fibers of the fiber suspension. A mixing device includes an inner chamber, an inlet, an outlet and a shear imparting device. The mixing device inlet is connected with a reactor outlet for receiving the loaded fiber suspension. The shear imparting device, such as a rotor, is disposed within the inner chamber and imparts lower shear forces to the fiber suspension.
