Description

稻秆本色浆抄造瓦楞原纸的方法 技术领域
本发明涉及一种稻秆本色浆抄造瓦楞原纸的方法。
背景技术
瓦楞纸板(箱)是全世界公认的绿色环保型包装产品。但随着人们环保观念的日益增强，再加上全球森林资源的日益匮乏和水土资源的日益短缺，生产纸箱用纸所需木材的采伐在许多国家都越来越受到限制，致使瓦楞纸箱业木材纤维的来源受到严重影响。
据国家统计局相关统计数据，2014年全国稻谷播种面积为3031万公顷，稻谷总产量为1.72亿吨，按照农作物产量与秸秆的估算法(1公斤稻谷约产1.1公斤秸秆)可知，我国每年约有1.89亿吨的稻谷秸秆，每年的储量极其丰富。
目前稻谷秸秆的处理的主要办法有：粉碎还田、就地焚烧、生物质发电、制浆造纸等。粉碎还田影响来年的播种，加重了病虫害；生物质发电由于受到运距的影响，超出运输半径运输成本成倍的增加，发电根本不赚钱；就地焚烧严重污染环境，已被国家明令禁止，因此利用稻谷秸秆制浆造纸可以起到资源再利用的效果。
发明内容
本发明要解决的技术问题是克服现有的缺陷，提供了一种稻秆本色浆抄造瓦楞原纸的方法。
为了解决上述技术问题，本发明提供了如下的技术方案：
稻秆本色浆抄造瓦楞原纸的方法，包括如下步骤：
(I)对稻秆本色浆进行打浆，打浆度控制在28-320SR，湿重3.2-3.8g；
(II)对废纸浆进行打浆，打浆度控制在28-300SR，湿重2.5-2.8g；
(III)按重量比为7:3，将稻秆本色浆和废纸浆混合，上抄纸机，抄造成瓦楞原纸。
进一步，所述稻秆本色浆通过包括以下步骤得到：
(1)将稻秆切成料段；
(2)料段先送汽蒸仓预蒸，再送入连蒸器进行蒸煮，蒸煮时按料段重量计加入1.5～2％的氢氧化钾，1.2～1.5％的亚硫酸铵，1.2～1.5％的三聚磷酸钠；
(3)蒸煮后的物料送双螺秆磨浆机进行搓摩分丝，洗浆，得到本色浆。
进一步，步骤(1)的料段长30-40mm。
进一步，蒸煮料液比为1:5，温度为120～125℃，时间为55～60min。
进一步，蒸煮后的物料先螺旋脱水，再送双螺秆磨浆机进行搓摩分丝。
本发明的有益效果：
1、实现了稻谷秸秆的资源有效再利用。
2、与纯废纸浆抄造的瓦楞原纸相比，本发明制作的瓦楞原纸具有更高的性能指标，环压强度、裂断长和平压指数得到明显改善，可用作高强瓦楞纸。
3、成浆效率高，浆得率可达到75～80％，纤维质量好，纤维平均长度达3.26um，长宽比值大。
4、系统产生的废水b/c比值高，可达到0.5左右，极易生化，水处理可采用生物处理的办法，为造纸零排放指明了方向。
