Description

一种去除水中氟离子滤料的制备方法
技术领域
本发明属于非织造过滤材料领域，提供了一种去除水中氟离子滤料的制备方法，制备的滤料可有效去除水中氟离子。
背景技术
我国地下水含氟地区的分布范围很广，因长期饮用含氟量高的水可引起慢性中毒，特别是对牙齿和骨骼产生严重危害。轻者患氟斑牙，重者则骨关节疼痛，甚至骨骼变形等，完全丧失劳动能力。高氟水的危害是严重的，WHO把饮用水中氟化物质量浓度0.5-1.5mg/L作为对人体有益的最佳浓度范围，我国生活饮用水卫生标准(GB5749-2006)规定，氟化物的质量浓度限值为1mg/L。因此需要去除饮用水中氟离子。
目前，国内外除氟方法主要有：混凝沉淀法、电渗析法、反渗透法、离子交换法和吸附法等。
中国发明专利CN106495350A公开了饮用水除氟除浊过滤器，采用活性氧化铝滤料通过分层除氟除浊。
中国发明专利CN105126738A公开一种脱除水中氟离子的多孔复合材料制备方法，采用多孔泡沫玻璃表面包覆一层稀土元素镧的氧化物制成。
中国发明专利CN102872812A公开一种去除水中氟离子的复合吸附材料及其制备方法，采用凤眼莲纤维素负载氧化锆可在任意条件下吸附除去水中氟离子。
发明内容
本发明目的是提供一种去除水中氟离子滤料的制备方法。
为达到上述目的，本发明采用的技术方案是：一种去除水中氟离子滤料的制备方法，包括如下步骤:
(1)普通纤网层制备：采用梳理成网或纺丝成网；
(2)蚕丝纤维层制备：采用静电纺丝制备成网；
(3)复合成型：一层蚕丝纤维层置于两层普通纤网层中间，采用针刺或水刺进行复合。
上述技术方案中，普通纤网层材料包括聚酯、聚丙烯、聚乙烯等。
上述技术方案中，蚕丝纤维层原料为桑蚕丝及其下脚料等；纺丝液由离子溶液溶解；离子溶液由甲酸和钙盐组成；钙盐包括氯化钙、硝酸钙、磷酸氢钙等。
与现有技术相比，本发明的优点和积极效果是：
本发明提供的去除水中氟离子滤料原料来源广，制备步骤简单，易操作。滤料材料采用蚕丝微纳米纤维结合价廉易得的非织造普通纤网，降低了制造成本，避免了苛刻的纺织加工条件。滤料采用离子沉积技术，可快速高效的去除水中氟离子。

附图2普通纤网层中纤维SEM形貌图
具体实施方式
下面结合实施例对本发明进一步描述：
实施例一
1.普通纤维层制备：聚酯短纤原料采用短纤梳理机梳理成网。
2.蚕丝纤维层制备：将0.5g氯化钙溶解于9.5g甲酸中，室温搅拌制备成离子溶液；将1.0g脱胶桑蚕丝溶解于离子溶液中，室温搅拌溶解制备成纺丝液。将纺丝液倒入注射器中，采用静电纺丝设备进行纺丝，获得微纳米蚕丝纤维。
3.复合成型：将一层蚕丝纤维置于两层聚酯纤维层之间，采用水刺进行复合，制备成非织造滤料。
实施例二
1.普通纤维层制备：聚酯短纤原料采用短纤梳理机梳理成网。
2.蚕丝纤维层制备：将20g氯化钙溶解于80g甲酸中，室温搅拌制备成离子溶液；将20g脱胶桑蚕丝溶解于离子溶液中，室温搅拌溶解制备成纺丝液。将纺丝液倒入液槽中，采用无针静电纺丝设备进行纺丝，获得微纳米蚕丝纤维。
3.复合加工：将一层蚕丝纤维置于两层聚酯纤维层之间，采用针刺进行复合，制备成非织造滤料。
实施例三
1.普通纤维层制备：将聚丙烯母粒放入熔喷纺丝机内，熔融纺丝制成聚丙烯熔喷非织造材料。
2.蚕丝纤维层制备：将20g氯化钙溶解于80g甲酸中，室温搅拌制备成离子溶液；将20g脱胶桑蚕丝溶解于离子溶液中，室温搅拌溶解制备成纺丝液。将纺丝液倒入注射器中，采用静电纺丝设备进行纺丝，获得微纳米蚕丝纤维。
3.复合加工：将一层蚕丝纤维置于两层聚丙烯熔喷纤维层之间，采用水刺进行复合，制备成非织造滤料。
由于滤料为层状结构，图1和图2为实施实例中蚕丝纤维层和普通纤网层中纤维的扫描电镜图，从图中可以看出，蚕丝纤维层中纤维为微纳米尺度，且纤维与纤维之间构成连续的孔状结构；普通纤网层中纤维也为微纳米尺度，纤维之间的孔隙率较高，这样多层结构构成的滤料有利于水分子的通过，便于纤维通过巨大的表面与氟离子结合。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等替换或改变，都应涵盖在本发明的保护范围之内。
