Abstract

一种利用农作物秸秆无污染造纸工艺,涉及造纸技术领域,包括如下工艺步骤,1)将秸秆用温水保温浸泡,浸泡12-72小时,泡软即可,水温控制在30-50摄氏度;2)将浸泡好的秸秆用搓揉机反复搓揉至纤维松散;3)利用类似弹棉花机的锯齿对辊逆向反复撕扯秸秆纤维,通过物理方法将秸秆纤维分离成絮状;4)然后将絮状纤维用碾压机高压碾压榨汁,清除有机木素,剩余纤维素成为造纸浆;5)在造浆工序中产生的污水调成中性污水,并添加絮凝剂沉淀,沉淀物用于加工肥料,澄清水循环利用。本发明工艺步骤简单,使用设备少,且能快速制得植物秸秆纤维,整个工艺过程无碱,环保、无污染。

Description

一种利用农作物秸秆无污染造纸工艺
技术领域
本发明涉及造纸技术领域,具体涉及一种利用农作物秸秆无污染造纸工艺。
背景技术
秸杆是可再生、可持续发展的重要资源。秸秆的不同部位,如茎杆、秸杆皮、叶、穰(髓)含有纤维素、半纤维素、木质素以及蛋白质等物质。不同物质应生产不同产品,做到物尽其用。目前,秸秆加工大多采用混合利用,即秸杆的茎杆、秸杆皮、叶、穰(髓)不加以分离,混合使用。
保护大自然的生态平衡是全球目前最关注的热点问题,而农业秸秆类废弃物的再利用成为关注的焦点。以往的秸秆类废弃物部分地区主要以焚烧为主,污染环境严重,随着科技的发展和人民对环境保护的认识,秸秆再利用开始应用在造纸、制作纤维板等工业领域。如专利申请号为200710028736X,专利名称为:一种植物纤维的成型方法就公开了植物秸秆纤维的制作工艺,但是该工艺的缺陷在于:制作植物秸秆纤维所用设备多,成本高,不适合简单制作。
发明内容
本发明所要解决的技术问题提供一种能够节约木材资源,保护环境,利用农作物秸秆无污染造纸工艺
本发明所要解决的技术问题采用以下技术方案来实现:
一种利用农作物秸秆无污染造纸工艺,包括如下工艺步骤,
1)将秸秆用温水保温浸泡,浸泡12-72小时,泡软即可,水温控制在30-50摄氏度;
2)将浸泡好的秸秆用搓揉机反复搓揉至纤维松散;
3)利用类似弹棉花机的锯齿对辊逆向反复撕扯秸秆纤维,通过物理方法将秸秆纤维分离成絮状;
4)然后将絮状纤维用碾压机高压碾压榨汁,清除有机木素,剩余纤维素成为造纸浆;
5)在造浆工序中产生的污水调成中性污水,并添加絮凝剂沉淀,沉淀物用于加工肥料,澄清水循环利用。
本发明的有益效果是:本发明工艺步骤简单,使用设备少,且能快速制得植物秸秆纤维,整个工艺过程无碱,环保、无污染。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解,下面结合具体实施例,进一步阐述本发明。
一种利用农作物秸秆无污染造纸工艺,包括如下工艺步骤,
1)将秸秆用温水保温浸泡,浸泡12-72小时,泡软即可,水温控制在30-50摄氏度;
