Improving the optical property of ONP (old newspaper) to that of OMG (old magazine) had the advantages of cost reduction, carbon dioxide reduction and possible drying energy saving in white duplex board process. In this study, the in-situ CaCO3 formation on ONP whole furnish and only on the fractionated ONP fines were analyzed morphologically by using FlowCAM (image analyzer). The morphological comparison between conventional calcium carbonate loading method (addition of ground or precipitated calcium carbonate) and in-situ CaCO3 formation method were also studied. Summary of the finding were presented as followed.
By in-situ CaCO3 formation on ONP whole furnish, the most of calcium carnonate was formed on the fines, and made the size of the fines larger. For the case of in-situ CaCO3 formation on only fractionated ONP fines, the size of the fines was the biggest, and it was found that there were more clean surface areas available for bonding in paper structure.
In-situ CaCO3 formation on ONP whole furnish improved first-pass retention and optical properties more than conventional calcium carnonate loading method.
The decrease in breaking length with the addition of calcium carnonate in the in-situ CaCO3 formation on ONP whole furnish was equivalent to or slightly lower than that of conventional calcium carbonate loading method.
Morphological image from the FlowCAM showed strongly attached ONP fines and calcium carbonate materials by the in-situ CaCO3 formation.
