Description

一种全竹浆低定量高强瓦楞原纸生产方法
技术领域
本发明涉及制浆造纸技术领域，具体来讲一种全竹浆低定量高强瓦楞原纸生产方法。
背景技术
瓦楞原纸在人们的观念中属于黑粗厚产品，主要用于包装箱起龙骨支撑作用。包装箱的强度取决于原纸强度。根据使用要求有普通瓦楞原纸与高强度瓦楞原纸之分。但是这类产品所用原料基本上都是再生纤维。因为成本原因，几乎不会添加原生纤维。因此，一个包装箱所用浆料可能已经经历过多次使用，由于回收使用次数的不同，必然导致部分产品质量波动，同时产品包装使用过程滋生的细菌数也在积累，造成被包装物品清洁程度受到影响。更为明显的是再生浆中仍含有少量的油墨成分无法完全去除。这会给后期包装物品的清洁度造成困扰。
随着人们环保健康意识的增强，以及国家对进口废纸的政策限制，原纸因成本问题会直接波及到产品品质。寻求新的生产原料补充瓦楞原纸生产原料制缺口，将成为一种新的方法。
再从技术的发展看，瓦楞原纸正在向低定量、高强度、全规格方向发展，现在能生产的定量已经出现了90-115g/m2的原纸，更为先进的将会出现60-90 g/m2的原纸，这将会大大降低包装成本。但这对纤维品质和抄纸技术有更高要求，势必增加生产成本。
从现有的技术领域看，低定量低成本瓦楞原纸还未有一种有效的工业方法实现。

（5）抄造：在长网纸机抄造，中间经过表面施胶、烘干、压光后卷取成成品。
作为上述技术方案的改进，所述一种全竹浆低定量高强瓦楞原纸生产方法，其特征在于：步骤（5）中，所述表面施胶工艺中，使用生物转化淀粉，淀粉为木薯淀粉或玉米淀粉中任意一种，淀粉使用浓度8-15%。
