摘　　要：以9年生中山杉木材为试验材料,通过测定其化学组成和纤维特性,结果表明其适合作为制浆材。采用正交试验方法,对中山杉进行硫酸盐法(KP法)蒸煮制浆特性进行初步研究,得出较佳的蒸煮工艺条件为:用碱量22%、硫化度27%、保温温度170℃和保温时间2.0 h,蒸煮后浆得率47.63%,卡伯值42.1,白度27.3%(ISO)。对其KP浆进行CEH、CEHP、TCF漂等不同漂序的组合漂白,白度增幅很大,均能达60%(ISO)以上,可漂性强。Nine-year-old Taxodium hybrid ＇ Zhongshanshan＇ wood was selected to evaluate the pulping characteristics, chemical composition and fiber characteristics show that it is a suitable species for pulp making, Orthogonal design was used to study the properties of the pulp prepared by kraft process （KP） , and it was concluded that the optimal process was achieved when the alkali usage, sulfidity, holding temperature and holding time were 22%, 27%, 170℃ and 2 h, respectively. In this condition, the pulp yield was 47.6% ; the Kappa number was 42.1 and the ISO whiteness was 27.3%. The KP pulp was bleached by using CEH, CEHP or TCF method. The sample whiteness increased by over 60% in all the cases, with good bleaching property.
