The present invention relates to the use of a depolymerized carboxylated cellulose solution for preparing an aqueous Precipitated Calcium Carbonate (PCC) slurry by slaking a material containing calcium oxide in water, followed by carbonation of the milk of lime thus obtained. The depolymerized carboxylated cellulose solution has a solid content of 25 wt. % to 40 wt. %, based on the total ...
When the carbonation stage was over (pH value is ca. 7.0–ca. 7.5), 81 ml of 5 g/l sodium stearate was added into the reactor while maintaining the stirring speed at 200 rpm for 10 min to ensure all PCC particles were surface modified (2.25–2.50 g sodium stearate was needed for 100 g PCC ()). ns-PCC powders as solids were collected by filtering and dried at 100 °C for 4 h before further ...
Precipitated calcium carbonate crystals of selected crystal habit. A pressure carbonation process is used to manufacture precipitated calcium carbonate. A slurry of calcium hydroxide is agitated in a pressurized reactor, and carbon dioxide is provided to a reactor to produce calcium ions and carbonate ions that react under pressure to produce precipitated calcium carbonate at a high reaction rate.
Precipitated calcium carbonate (PCC) Calcium carbonate (CaCO3) is widely found in almost all living creatures, as well in some human tissues. Compared with other inorganic materials, over the years, CaCO3 has Carbonates Evaporites Fig. 1 a Estimated global consumption of PCC by 2013 and b estimated global consumption of FGGC by 2013
cal performance (Clark, 1992). Precipitated calcium carbonate (PCC) is also used in papermaking as a coating and filler mate-rial. In conventional production of synthetic (i.e., precipitated) calcium carbonate, flue gas containing CO. 2. is bubbled though a hydrated lime slurry (calcium hydroxide), from which calcium carbonate precipitates.
