摘要
对杉木进行制ＣＭＰ中间试验。杉木树龄１０年，基本密度３０８ｋｇ／ｍ￣３，ＮａＯＨ＋Ｎａ＿２ＳＯ＿３用量为５％＋１４％，纸浆得率８８．４％；在游离度为２５０ｃｓｆ时，磨浆电耗２２．３ＭＪ／ｋｇ，平均纤维长度２．６ｍｍ，紧度３６５ｋｇ／ｍ￣３，抗张指数４８Ｎ·ｍ／ｇ纸浆白度２８．７％ＩＳＯ，成纸松厚，有很高的不透明度。
Cunninghamia lanceolata chips aged 10 years with basic density of 308 kg/m￣3 were used in pilotscale chemimechanical pulping tests. The pulps with a level of chemical usage of 5%sodiurn hydroxide and14%sodium sulphite(on od wood)yielded in 88.4%at a given freeness level of 250 mL. Specific energyconsumption was 22.3 MJ /kg for refining and the fibre length of the pulp was 2.6mm,the density of thesheet 365 kg/m￣3,the tensile index 48 N·m/g and brightness 28.7%ISO. The pulps could be used in morebulky productions.
