The pulp is pretreated with a ionic polymer prior to being impregnated with the filler. Different conditions of pH and temperature are specified depending on whether the filler is a precipitated calcium carbonate or a ground calcium carbonate.
Deposit Problems Troubleshooting Guide
Calcium oxalate deposits can be a serious problem in systems where the oxalate ion is formed during oxidative bleaching of kraft pulp. Should these deposits occur on the paper machine it is likely that better pulp washing could solve the problem or at least prevent the problem from reaching the paper machine.
Paper mill residuals: Free soil amendment available to Upper
Each mill does have a unique product depending on the fiber source and processing type affecting the pH and calcium to nitrogen C:N ratio. Paper mill residuals do have a liming property composed of fine-grained calcium carbonate. The average calcium carbonate content from the three mills range from 25 to 38 percent.
Calcium Carbonate Pulp Paper Mill
This paper was given at the Jan. 1997 conference of the Technical Section Canadian Pulp and Paper Association under the title "Mill Experiences with Precipitated Calcium Carbonate PCC in Papers Containing Mechanical Pulp" and will appear in Pulp and Paper Canada later in 1997.

During this process sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide also known as quicklime to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process calcium carbonate is formed. Calcium carbonate is the major component of "lime" or ground agricultural limestone.

Recovery of calcium carbonate waste as paper filler in the
For this reason pulp mills dispose the lime mud mainly calcium carbonate from the causticizing process as a waste to purge silicon from the pulping system. The calcium carbonatein the lime mud waste may be recovered as paper filler. Precipitated calcium carbonate PCC is commonly added to paper in the papermaking
Removal of organics and calcium hardness in liner paper
Calcium was efficiently removed in CO 2 stripping unit where excess alkalinity was consumed to form calcium carbonate. No additional chemical such as caustic soda was necessary to facilitate the formation of calcium carbonate since the degassing of CO 2 increased the pH level in the CO 2 stripping unit. Calcium removal efficiency approached
PCC and Pulp and Paper Carmeuse
Paper-making requires large quantities of PCC precipitated calcium carbonate in order to maximize paper& 39;s whiteness opacity and consistency. Paper& 39;s basic component pulp also needs lime during the manufacturing stage. PCC is used also in other industries such as paint and coatings or floor coverings.
