“…Figure 4(a) shows the bulk of papers containing different fillers and how much the paper bulk was affected by the high wet pressing pressure. As presented previously in the literature (Jung and Seo 2015a;Jung and Seo 2015b;Kang et al 2020), the HCC-containing paper always gave remarkably higher bulk than the others, and the one pressed with two-fold higher wet pressing pressure, HCC-H, kept the bulk equivalent to GCC. The stiffness of the papers containing HCC that were pressed with high wet pressing pressure were still higher than those containing GCC and the pGCC in Fig.…”

“…It is known that the HCC-containing paper has much higher bulk than the GCCcontaining paper, while keeping high tensile strength and high stiffness from the previous study (Jung and Seo 2015a;Jung and Seo 2015b;Choi and Seo 2016;Choi et al 2018;Kang et al 2020). In the previous study, the authors demonstrated that the HCC containing paper could be used for developing highly filled paper without compromising essential mechanical properties (Kang et al 2020). This time, the authors tried to make use of the high bulk of HCC containing paper for developing the high solid content paper.…”

“…HCC seemed to resist compressive pressure applied during the papermaking process, and to induce high bulk in paper. Further explanation of the structure should be found in the references (Jung and Seo 2015;Choi and Seo 2016;Choi et al 2018;Kang et al 2020). The HCC in Fig.…”

“…However, the HCC had some rigidity to resist against the compressive pressure for developing high bulk during wet pressing, and should give low Bekk smoothness. However, in the previous study listed in the literature (Jung and Seo 2015a;Jung and Seo 2015b;Choi and Seo 2016;Choi et al 2018;Kang et al 2020), it was demonstrated that the HCC was partially deformable under the wet pressing condition, but not totally collapsible. Therefore, the three different fillers including the HCC-H gave similar smoothness with overlapped standard deviations.…”

“…Hybrid calcium carbonate (HCC) was prepared by producing preflocculated flocs with GCC and calcium oxide and then by injecting carbon dioxide to the flocs to make semi-rigid agglomerates of the GCC and newly formed PCC from the calcium oxide (Jung and Seo 2015a;Jung and Seo 2015b;Choi and Seo 2016;Choi et al 2018;Kang et al 2020). It was demonstrated that the paper containing 40% HCC had equivalent physical properties to the paper containing 30% GCC as long as 3 wt% cationic starch was added to the HCC containing paper for supplementing low bonding properties (Kang et al 2020). In that case, there were no loss or even better properties of tensile strength, bulk, stiffness, and smoothness with 10% higher content of filler.…”

Hybrid calcium carbonate (HCC) is prepared by pre-flocculating calcium oxide and ground calcium carbonate (GCC) with ionic polymers, and by injecting carbon dioxide to the pre-flocculated flocs until termination of the reaction at neutral pH. When used in papermaking, HCC gave higher bulk, higher stiffness, and higher tensile strength than GCC did. Furthermore, when higher wet pressing pressure was applied to the paper containing HCC, higher solid content was achieved with still better stiffness, smoothness, and tensile strength in comparison with the paper containing GCC. Actually, very high bulk of the HCC containing paper was compromisingly reduced to obtain high solid content by applying higher wet pressing pressure. Higher solid content achieved by combination of HCC technology and higher wet pressing pressure resulted in paper drying energy savings of more than 10%, while a high quality of all the essential printing paper properties was maintained. Drying energy savings may contribute to greenhouse gas (GHG) reduction and lowering of the paper production cost.

Nano‐calcium carbonate (nano‐CaCO3) is a tiny inorganic filler created in the 1980s. It boasts a high specific surface area, excellent biocompatibility, and nontoxicity. As a result, it finds extensive applications in the rubber, plastic, and paper industries. This paper intends to give a general overview of the preparation process, surface modification, and application of nano‐CaCO3. In particular, the preparation process conditions, the characteristics of the prepared nano‐CaCO3, the method and mechanism of surface modification, and also the main application research progress of nano‐CaCO3 are described comprehensively. This paper has a good guiding effect for the researchers and related staff engaged in the study of nano‐CaCO3.

Forensic document examination has been considered one of the most important fields in the forensic science. For this, a quick, effective, and cheap techniques for evaluation of forensic evidence is highly required. This study explores the comparison of A4 document paper by chemical and physical analysis. 16 of white A4 paper from different brands were analyzed by FTIR for investigation of structural characteristics. Video Spectral Comparator 8000 has been used to compare the A4 papers under different light source. The inorganic filler composition in the paper is also explored by ICP‐OES. The calcium carbonate content in document papers play a discriminant role which found to be between 16.02 % and 35.54 %. Also, water contact angle has been utilized in order to examine the surface of paper which is generally related to the inorganic filler and other additives. The WCA results ranged between 83° and 111° that enable quick and easy way to compare A4 document papers. The experimental results have demonstrated that besides FTIR methods, other methods such as ICP‐OES for elemental composition, WCA for wetting test, VSC for visualization under different light of source could have been applied for comparison of document papers in case of criminal cases.
