Abstract

In this study, effects of KBH4 (PB), NaBH4 (SB), Etibor-48 (E48), Etidot-67 (E67), and colemanite (Col) on kraft pulp and paper properties of Scots pine (Pinus sylvestris L.) wood were evaluated. The control and boron compound-added kraft pulps were obtained under constant cooking conditions. The boron compounds were used as digester additives in different ratios (2 % and 4 %). The addition of boron compounds to kraft cooking liquor resulted in increases screened and total yield of pulps. The highest screened yield (52.05 %) and total yield (55.09 %) were obtained from PB-4 pulp. The lowest reject ratio (0.61 %) and kappa number (34.60) were determined from PB-2 pulp. Furthermore, the highest tensile properties of handsheets were obtained from E67-4 pulp. Also, E48-4 pulp had the highest burst index and tear index values. E48, E67, and Col are cheaper than PB and SB. From these boron compounds, pulps with relatively low pulp yield but stronger can be obtained.

硼化合物-添加苏格兰松硫酸盐纸浆

本研究评估了KBH4（PB）、NaBH4（SB）、Etibor-48（E48）、Etidot-67（E67）和Col（Col）对樟子松（Pinus sylvestris L.）木材硫酸盐浆和纸张性能的影响。在恒定的蒸煮条件下获得对照和添加硼化合物的硫酸盐浆。硼化合物以不同的比例（2%和4%）用作蒸煮器添加剂。在硫酸盐蒸煮液中加入硼化合物，可提高纸浆的筛分率和总产率。PB-4纸浆的筛选收率最高（52.05%），总收率最高（55.09%）。PB-2纸浆的废品率（0.61%）和卡伯值（34.60）最低。此外，E67-4纸浆获得了最高的手抄纸拉伸性能。E48-4纸浆的爆裂指数和撕裂指数最高。E48、E67和Col比PB和SB便宜。从这些硼化合物中可以获得出纸浆产率相对较低但强度更强的纸浆。
