Abstract
本发明提供了一种快速评价杨木烧碱蒽醌法制浆工艺优劣的方法，包括如下步骤：a)测定杨木原料的木素含量X(%)；b)采用烧碱蒽醌法蒸煮，制备杨木浆，用碱量Y（%）以Na2O计；c)测定蒸煮废液残碱含量A（%）、浆料的卡伯值K；d)根据如下公式，计算杨木烧碱蒽醌法制浆工艺的优劣，若K≤Z1=X×21.7+Y×38.9，A≤Z2=X×0.19+Y×0.2，则判定为合格，否则判定为不合格。方法简单高效，实用性强、适宜推广，为快速调整杨木烧碱蒽醌浆蒸煮工艺提供了一种新方法。

[0001] 本发明属于制浆造纸领域，涉及一种快速评价杨木烧碱蒽醌法制浆工艺的方法。
背景技术
[0002] 造纸工业废水是工业污染源之一，大概占我国工业总废水量的10%左右。制浆造纸工业废水主要有高浓度有机废水，还含木素、硫化物、氯化物等污染物。造纸工业废水最大的特点是废水量大，C0D质量浓度高，但随着造纸工业环保力度的加大，造纸废水的污染逐年降低，2010年造纸行业废水中C0D的总产生量在95.2万吨左右；不同类型造纸企业排放的污染情况差异性大，不同原材料、不同的制浆造纸工艺，其排放废水中C0D的浓度有几倍到几十倍的差异。因此，降低造纸废水污染及排放量迫在眉睫。
[0003] 造纸废水主要有两个来源，一是蒸煮废液，因为在蒸煮阶段会产生大量的有色废水，其中木质素及其衍生物是主要的污染成分；二是漂白，漂白用的漂液大都含有氯元素，这样会产生有毒物质和致癌物质，如二噁英，这些有害物质都会影响人们的身体健康。随着人们环保意识的不断提高，人们开始关注周边的环境，解决当前的环境问题是重中之中。国家的环保要求也越来越严，对排放标准越来越高，在“十二五”期间，化学需氧量(C0D)排放总量预计在2015年比2010年降低10-12%。因此，寻找非木材原料清洁制浆新技术，减少对环境的污染，是制浆造纸企业的重要课题研究之一。
[0004]当前，杨木正在成一种越来越重要的纤维资源，特别是在造纸领域。其质细软，性稳，价廉易得。常做为榆木家具的附料和大漆家具的胎骨在古家具上使用。这是所说的杨木亦称“小叶杨”，常有段子般的光泽，故亦称“缎杨”，不是本世纪中才引进的那种苏联杨、大叶杨、胡杨等。杨木常有“骚味”，比桦木轻软。桦木则有微香，常有极细褐黑色的水浸线。这是二者的差别。
[0005] 杨木是一种主要的造纸资源，传统的杨木多采用碱法化学制浆，由于杨木原料中杂细胞较多使纸浆滤水性能差，黑液的提取率低，而硅含量较高，给碱回收部分带来困难，造成环境的污染。随着造纸工业面临造纸原料、能源和环境问题矛盾的日益突出，研究出新的制浆工艺是必然选择，对造纸工业的发展起到重大作用。
[0006] 然而，目前的对制浆工艺优劣的评价主要以最终抄造的纸张的物理性能为准，在实际工艺摸索过程中，蒸煮后的浆料首先要平衡水分24h，再抄造纸张，得到的纸张平衡水分24h后才能检测各项物理性能指标，整个过程需要3天以上。在大规模的单因素和正交实验过程中，整个检测周期过长，无法及时有效地调整制浆工艺，导致生产的纸张连续出现不合格问题，使企业蒙受巨大经济损失。
发明内容
[0007] 本发明的目的就在于克服现有技术的上述不足，提供一种快速评价杨木烧碱蒽醌法制浆工艺的方法，本发明将木素含量、用碱量、残碱、卡伯值引入评定指标中，介绍一种残碱和卡伯值快速评价制浆工艺优劣的方法。从而可以及时调整浆料的生产工艺，为最优蒸煮的选择优化提供依据。
[0008] 为解决上述技术问题，本发明是通过以下技术方案实现的:
[0009] 本发明提供了一种快速评价杨木烧碱蒽醌法制浆工艺优劣的方法，包括如下步骤:
[0010] a)测定杨木原料的木素含量X(% );
[0011] b)采用烧碱蒽醌法蒸煮，制备杨木浆，用碱量Y(% )以Na2(H+ ;
[0012] c)测定蒸煮废液残碱含量A(% )、浆料的卡伯值K ;
[0013] d)根据如下公式，计算杨木烧碱蒽醌法制浆工艺的优劣，若K彡Zi =XX 21.7+YX38.9，A彡Z2= XX0.19+YX0.2，则判定为合格，否则判定为不合格。木素是由苯基丙烷结构单元构成的天然高分子化合物，在生产化学浆时，要去除原料中80%以上的木素；木素含量是制定合理蒸煮与漂白工艺的重要条件，木素质量分数高，蒸煮困难，消耗的化学药品也相对较多。
[0014] 步骤a)中所述的杨木原料经洗涤、压榨、风干、切片后，削成火柴梗大小存放在聚乙烯密封袋中平衡水分24h以上。
[0015] 步骤a)中所述木素含量按GB/T2677.8 一 1994测定。
[0016] 步骤a)中所述洗涤的步骤为杨木先经过自来水洗涤多次，把附着于杨木表面的小量白色粉末和尘垢洗去。防止其表面的金属及其他成分对后续的制浆和漂白过程造成不利影响。
[0017] 步骤a)中所述压榨的步骤为用斧头将杨木敲裂成宽约4〜5cm长的条状，然后将杨木条经压榨机压榨，去除细胞腔中的空气和部分的滤液。经过压榨后杨木材在表面形成径向走向的条纹，在蒸煮过程中易于均匀地渗透蒸煮药液，加快木材与蒸煮液反应的速率。
[0018] 步骤a)中所述风干的步骤为将经过洗涤、压榨后的杨木条曝晒3〜7天，均匀水分，当杨木的水分达到10%左右时即可；
[0019] 步骤a)中所述切片的步骤为压榨风干后的杨木条用切片机将杨木条切成长2〜3cm、宽为1〜1.5cm的杨木片，最后装袋密封，平衡水分备用。
[0020] 步骤c)中所述残碱含量按《制浆造纸分析与检测》中黑液有效碱的测定方法测定。
[0021] 步骤c)卡伯值按GB/T 1546-1989测定
[0022] 本发明的有益效果:
[0023] 1.本发明将木素含量、用碱量、残碱、卡伯值引入评定指标中，介绍一种残碱和卡伯值快速评价制浆工艺优劣的方法。从而可以及时调整浆料的生产工艺，为最优蒸煮的选择优化提供依据。
