【摘要】 本文对厄瓜多尔6年生蓝花楹原料的化学成分进行了分析发现该树种有较好的纤维特性。硫酸盐法制浆的试验表明:蓝花楹是一种典型的热带材种;在硫化度25%、活性碱用量18%、在165℃保温80min的硫酸盐法蒸煮条件下,可以得到卡伯值为24.3、细浆得率46.9%和纸张裂断长7.62km的KP浆。更多还原

【Abstract】 Six years old Jacaranda copaia wood was used to cook in Kraft process in lab. scale. Its chemical composition was also analyzed. The results showed that this tropical species was a little difficult to be digested with Kraft method. The optimum conditions of Kraft Pulping was as follows: sulfidity 25%, alkali sodium charge 18%, 165℃ for 80min. The pulp yield was 46.9%, the kappa number was 24.3, and the breaking length of handsheets was 7.62 km.更多还原
