Description

棉短绒制作可降解地膜纸的方法 技术领域
本发明涉及一种棉短绒制作可降解地膜纸的方法。
背景技术
新疆是我国棉花主产区，其棉花种植面积14年已经达到全国总种植面积的一半以上，达到3500万亩。每年的棉花总产量约400万吨，棉短绒的产量约40万吨左右。
新疆春季经常出现大风降温、倒春寒等极端天气，为保证棉花及时出苗、保墒情，棉花播种不得不采取地膜覆盖保温。由于塑料薄膜不可降解，又没办法回收，所以，“白色污染”越来越严重。
如何解决“白色污染”问题？除加强塑料薄膜的回收，找到可替代塑料薄膜的可降解地膜势在必行。
发明内容
本发明要解决的技术问题是克服现有的缺陷，提供了一种棉短绒制作可降解地膜纸的方法。
为了解决上述技术问题，本发明提供了如下的技术方案：
棉短绒制作可降解地膜纸的方法，包括如下步骤：
(1)将棉短绒及助剂送入双螺杆磨浆机中进行搓摩分丝，所述助剂为KOH和三聚磷酸钠；
(2)将搓摩分丝后的浆料送入滞留槽，停留反应65-70min后，进行消遣、洗涤、除渣、打浆；
(3)经步骤(2)处理的浆料送抄纸机抄造成地膜纸，抄造时按吨浆计，加入120～130公斤的玉米淀粉，15～20公斤造纸湿强剂，10～12公斤纸张防水防潮剂。
进一步，步骤(1)按棉短绒重量计，加入2.5～3％的KOH，1.5～2％的三聚磷酸钠。
进一步，步骤(1)双螺杆磨浆机的出口温度控制在120-125℃。
进一步，步骤(3)地膜纸的定量为50-55g/m2。
进一步，所述棉短绒为三道绒。
本发明的有益效果：
1、抄纸效率高可达到90—95％。
2、地膜纸中含有大量的磷、钾，降解后为棉花生长提供了养料。
3、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。
4、工艺流程简单，造纸成本低。同传统塑料薄膜相比可节省成本1/3左右。
具体实施方式
以下对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。

(2)三道绒原料经纤维压实器均匀的输送至双螺杆磨浆机(厂家：江苏金沃机械有限公司型号：FD180)并加入除蜡除脂的助剂进行搓摩分丝，按棉短绒重量计，助剂的加入量：2.5～3％的KOH、1.5～2％的三聚磷酸钠(配成水溶液后加入)，双螺杆磨浆机的出口温度控制在120～125℃。
(3)搓摩分丝后的浆料送入滞留槽，在滞留槽中进行充分反应得到粗浆，停留时间为65～70min。
(4)步骤(3)所得的粗浆经消遣后，输送至挤浆机进行洗涤。
(5)洗后浆经高浓除渣后，用锥度磨浆机进行循环打浆，再进行低浓除渣。
(6)将步骤(5)的浆料送抄纸车间，用叠网纸机抄造成50—55克/平方米的地膜纸，在抄造地膜纸过程中按吨浆计，加入120～130公斤的玉米淀粉，15～20公斤造纸湿强剂(骏能化工，河北厂，PPE型)，10～12公斤纸张防水防潮剂(骏能化工，河北厂)。
最后应说明的是：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，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。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。
