技术领域
本发明属于功能性纤维技术领域,具体地说,尤其涉及一种低熔点超短涤纶纤维制备反渗透RO膜的方法。
背景技术
一般水的流动方式是由低浓度向高浓度流动,当水加压后,将由高浓度向低浓度流动,即为逆渗透,由于RO膜的孔径是发丝的百万分之一(0.0001mm),细菌、病毒等的孔径是其5000倍,因此,只有水分子及部分矿物离子能够通过,其它杂质及重金属均由废水管排出。现有的抗污染反渗透膜材料大多采用涤纶长纤维经编织而成,编织而成的织物通过浸轧硬挺剂使纤维内部、纤维之间或纤维表面形成薄膜,但由于采用涤纶长纤维制成,纤维分散性降低,制备过程中易存在杂质,从而导致RO膜品质下降,同时大多生产过程中需要人工反复操作,导致生产效率低下。

具体实施方式
下面结合附图和具体实施方式,对发明进一步说明:
如图1—图4所示,一种低熔点超短涤纶纤维制备反渗透RO膜的方法,包括以下步骤:
(1)将涤纶切片粉碎处理,浸泡2~3h后进行清洗,在清洗的过程中高速搅拌,搅拌后置于转鼓真空干燥机内真空干燥,制得含水率≤100ppm的涤纶颗粒;
(2)将涤纶颗粒加入双螺杆挤出机内,经计量设备均匀分配至复合组件中,反应一段时间后,挤出复合熔体,熔体经过滤器过滤后进入纺丝箱体,纺丝组件喷丝,形成低熔点超短涤纶纤维初生丝;
(3)初生丝经环吹、甬道冷却、上油、牵引卷绕后松弛,卷曲,再烘干,制得低熔点超短涤纶纤维;
(4)将低熔点超短涤纶纤维在经编机上编织成胚布;
(5)将胚布置于定型装置中进行高温定型,再经水洗、预烘、烘干,制得反渗透RO膜,定型装置内填充有整理液,按重量份计整理液由以下组分组成:8~10份聚乙烯、30~40份丙烯酸乙酯、5~10份过氧化锌、8~10份抗菌剂以及3~6份乙酸乙烯。
低熔点聚酯纤维在合成过程中加入了具有不对称结构的改性单体,破坏了分子链的规整性,使得共聚酯的结晶能力降低,结晶度和结晶完善程度降低,故熔点随之降低,低熔点聚酯纤维在较低加热温度条件下熔融,使得聚酯纤维互相粘合在一起,从而满足RO膜所需求的细旦、分散的要求。
所述步骤(2)中纺丝组件包括经螺栓上下连接为一体的砂杯1、分配板2以及喷丝板3,砂杯1上方盖设有盖板4,砂杯1表面中心处连通有沿盖板4内部横向延伸的管道5,管道5端部设有与熔体相连通的铝嘴6,铝嘴6处于盖板4侧部端面。利用砂杯,充分过滤熔体中杂质,提高纤维纯度,熔体经砂杯1过滤后再由分配板2分配计量后由喷丝板3喷出。

本发明中胚布自上导入辊和下导入辊之间导入,绕设于支撑辊15表面后再由上导出辊和下导出辊之间导出,启动第一微型电机,第一微型电机驱使滑动轮13绕圆周转动,滑动轮下13压T形连接架11下落,令导入辊组和导出辊组之间的胚布充分浸入整理液中,同时,启动第二微型电机,从动齿轮19带动旋转齿轮18转动,旋转齿轮18带动旋转座17沿圆周方向转动,旋转座17底部的搅拌桨23对整理液进行搅拌,确保整理液浓度保持均匀,定位片20、调节片21以及旋转片22的配合,提高旋转座17抗扭性,令其免受整理液流动过程中带来的扰乱,当浸轧槽8内整理液逐渐减少,需要添加时,启动伸缩气缸33,连接耳32带动调节杆31前端下落,调节杆31后端上移,与调节杆31后端相连接的斜杆30向上受力后带动滑动块27沿引流槽26向上,促使插管28插入补液槽24,令补液槽24内整理液流入浸轧槽8内。
