Description
技术领域
本发明涉及一种造纸工艺，尤其涉及一种造纸替代纤维乌本木渣浆工艺。
背景技术
一般采用原生木浆和废纸木浆两种原料，其中，原生木浆具有更好的耐破度和性能，但成本较高，对森林、水、电消耗较大，同时污染物排放较多。从可持续发展的角度，行业内的趋势是尽可能减少原生木浆的使用，节约有生资源，尽可能地回收利用可再生资源。而废纸木浆则是一种十分重要的可再生资料，其造纸生产成本较低，但仍存在产能不足的问题。
发明内容
因此，针对现有技术的不足，本发明的目的在于提供一种的新型造纸替代纤维乌本木渣浆工艺。
一种造纸替代纤维乌本木渣浆工艺，包括以下步骤：
(1)、将乌本木渣浆原料通过链板机上料到水力碎浆机碎解，经疏解机疏解后进入卸料池，所述卸料池连接双圆盘磨机的入口，双圆盘磨机的出口连接磨后池，所述双圆盘磨机的另一口连接于双圆盘磨机的入口，经双圆盘磨机处理后的一级良浆流入到磨后池，所产生的二级良浆回流到入口并在双圆盘磨机上再一次研磨，使浆料能在盘磨循环打浆，乌本木渣浆加入量：70-100kg/吨纸；
(2)、通过将原生木浆、乌本木渣浆、美废长纤浆、美废短纤浆、国废长纤浆、国废短纤浆合理调配按一定比例送至面、芯、底纸机配浆池内混合均匀；
(3)、将面、芯、底配配浆池的配浆分别通过管道转移到面、芯、底纸机成浆池内，在转移过程中，同时加入增强剂，所述增强剂可以为阳离子型聚丙烯酰胺或阳离子淀粉，增强剂添加量：8-10kg/吨纸；
(4)、面、芯、底纸机成浆池内的纸浆再经过网部、压部、前干部、施胶淀粉工艺处理、后干部、压光机、卷取、成品包装，其中，进入网部时，同时加入干强剂，所述干强剂可以为阴离子聚丙烯酰胺、羧甲基纤维素、羧甲基淀粉；干强剂与纤维能形成氢键结合的高聚物，干强剂添加量为40-50kg/吨纸，施胶淀粉添加量为40-50kg/吨纸。
进一步地，在步骤(2)中，原生木浆乌本木渣浆、美废长纤浆、美废短纤浆、国废长纤浆、国废短纤浆的质量百分比为6：9：30：25：20：10。
本发明一种造纸替代纤维乌本木渣浆工艺的有益效果在于：本发明优化目前化工添加工艺，在乌本木渣浆替代部分原生木浆和美废的情况下，通过优化调整干强剂、增强剂、施胶淀粉的用量，保证优质环保牛皮箱板纸达到出厂标准和客户要求，合理的化工添加工艺，有效的提高成纸的耐破强度，保证成纸质量；并且通过技术改造解决了对乌本木渣浆难以处理的纤维束，使渣浆可以替代原生的针叶木浆使用，并有效的降低整体的浆料成本，变废为宝；美废用量少，减少对美废的依赖程度。
附图说明
图1为本发明新型造纸替代纤维乌本木渣浆工艺的工艺流程图。
具体实施方式
为了使本发明的技术方案能更清晰地表示出来，下面结合附图对本发明作进一步说明。
如图1所示，本发明提供一种造纸替代纤维乌本木渣浆工艺，用于生产成品纸，该造纸替代纤维乌本木渣浆工艺包括以下步骤：
(1)、将乌本木渣浆原料通过链板机上料到水力碎浆机碎解，经疏解机疏解后进入卸料池，所述卸料池连接双圆盘磨机的入口，双圆盘磨机的出口连接磨后池，所述双圆盘磨机的另一口连接于双圆盘磨机的入口，经双圆盘磨机处理后的一级良浆流入到磨后池，所产生的二级良浆回流到入口并在双圆盘磨机上再一次研磨，使浆料能在盘磨循环打浆；在不损坏乌本木纤维性质和结构的前提下，把难以处理的木浆渣通过研磨进一步提升纤维帚化度，使原本难以分解的纤维束得到分解，乌本木渣浆加入量：70-100kg/吨纸；
(2)、通过将原生木浆6％、乌本木渣浆9％、美废长纤浆30％、美废短纤浆25％、国废长纤浆20％、国废短纤浆10％合理调配按一定比例送至面、芯、底纸机配浆池内混合均匀，保证纤维间的结合强度和脱水能力，从而得到优质环保牛皮箱板纸面、芯、底层浆料；
(3)、将面、芯、底配配浆池的配浆分别通过管道转移到面、芯、底纸机成浆池内，在转移过程中，同时加入增强剂，所述增强剂可以为阳离子型聚丙烯酰胺或阳离子淀粉，增强剂添加量：8-10kg/吨纸；
(4)、面、芯、底纸机成浆池内的纸浆再经过网部、压部、前干部、施胶淀粉工艺处理、后干部、压光机、卷取、成品包装，其中，进入网部时，同时加入干强剂，所述干强剂可以为阴离子聚丙烯酰胺、羧甲基纤维素、羧甲基淀粉；干强剂与纤维能形成氢键结合的高聚物，以提高结合力和纤维本身的强度，干强剂添加量：40-50kg/吨纸，施胶淀粉添加量：40-50kg/吨纸。
本发明一种造纸替代纤维乌本木渣浆工艺的有益效果在于：本发明优化目前化工添加工艺，在乌本木渣浆替代部分原生木浆和美废的情况下，通过优化调整干强剂、增强剂、施胶淀粉的用量，保证优质环保牛皮箱板纸达到出厂标准和客户要求，合理的化工添加工艺，有效的提高成纸的耐破强度，保证成纸质量；并且通过技术改造解决了对乌本木渣浆难以处理的纤维束，使渣浆可以替代原生的针叶木浆使用，并有效的降低整体的浆料成本，变废为宝；美废用量少，减少对美废的依赖程度。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
