| titleOfInvention | Preparation method of cubic light calcium carbonate filler |
| abstract | Hair brushThe preparation process of light cubic calcium carbonate filler includes the following steps: taking calcium hydroxide fine pulp, and fully carbonizing to obtain cooked pulp as mother liquor; adding the crystal form control agent into the calcium hydroxide fine slurry to prepare a mixed solution; and slowly dripping the mixed solution into the mother solution, simultaneously carbonizing, dripping the mixed solution from the upper part of the reactor, simultaneously discharging materials from the bottom of the reactor at the same flow rate, and carbonizing to the end point to obtain the cubic light calcium carbonate filler. The cubic light calcium carbonate filler prepared by the invention has the specific surface area of 2.0-4.5m 2 The specific surface area of the filler is reduced, so that the adsorption of the filler to AKD can be reduced, the sizing effect is improved, the tensile strength and the internal bonding strength of the paper sample are improved, the dosage of AKD is saved, and the papermaking cost is reduced. |
