벌크향상제의 주요 물성에 따른 백판지의 벌크와 건조에너지 평가

다국어 초록 (Multilingual Abstract)

In this study, we investigated the properties of wood powders (WPs), which are used in the Korean duplex board industry, and determined their effect on the bulk and the drying energy requirement of paperboard. Three types of WPs were collected; their chemical compositions were analyzed, and the physical properties, including particle size and distribution, particle shape, and zeta potential, were measured. Handsheets containing the WPs were then made, and the physical properties and drying energy requirement were determined. The chemical compositions of the WPs were similar to the composition of common softwood and hardwood, except for the ash content. This suggests that papermakers must monitor the ash content of the WPs carefully. The particle size and distribution, and the particle shapes showed the regularity of WP particles. The three types of WPs improved the bulk and reduced the strength of the handsheets. The WP containing the largest and the most regular particles was the most effective at improving the bulk and reducing the drying energy requirement. Therefore, the particle size and distribution in the WP are the most important properties to obtain the desired benefits in a duplex board mill.
