Description

核电站用玻璃纤维水过滤纸及其制备方法
技术领域
本发明涉及核电站水过滤领域，具体涉及一种抗SiO2析出的高精度玻璃纤维水过滤纸及其制备方法。
背景技术
核电站的水回路系统要使用不同尺寸和精度的过滤器来保持水质的纯净，防止水中的腐蚀产物和悬浮的固体颗粒物对回路系统产生危害，保证核电站的正常运行。过滤器用滤芯就过滤精度而言，最初只有5μm、25μm、100μm，但随着国际核电技术的发展，对一回路水质的要求不断提高，需要使用过滤精度为0.45μm和1μm的高精度滤芯。为了提高核电站水过滤器滤芯的使用寿命及过滤精度，国内核电站开始采用玻璃纤维的滤芯滤器替代传统纸质滤芯滤器，但玻璃纤维的主要成分是SiO2，SiO2在酸性介质中容易析出，可溶的SiO2无法去除，且生成的硅酸盐在燃料元件棒最热部位会优先析出而沉淀，沉淀物影响堆芯的反应且加重金属管件的腐蚀。因此，二氧化硅的浓度必须加以有效控制，以保障核电站的安全稳定运行。核行业标准《EJ/T345-2005压水堆核电厂水化学控制》中规定SiO2析出量必须小于0.8PPM，实际应用中期望SiO2的析出量小于0.6PPM。国际上能达到要求的仅有美国Pall和加拿大3L两家公司，其滤材不单独出售，滤芯价格昂贵、供货周期长，造成核电站的运行成本增高。
目前国内厂家在玻纤滤材生产时采用有机硅型贵重添加剂，对玻纤表面进行处理，使SiO2的浸出得到一定程度的改善，可以生产过滤精度5μm、25μm的水过滤纸，SiO2的析出量小于200PPM。中国专利CN103084005B公开了一种核级水过滤器滤芯所用滤材的改性方法，采用聚丙烯酰胺类聚合物水溶液处理市售的过滤精度为5μm、25μm的玻璃纤维滤材和纸质滤材，处理后SiO2浸出量比未处理前减少40％～80％，按其处理效果的最高值计算，所得滤材SiO2的析出量仍有40PPM，远达不到行业标准小于0.8PPM的要求。
发明内容
为解决现有核电站水过滤器过滤精度达不到要求，玻璃纤维滤材滤芯在使用过程中SiO2析出的技术问题，本发明提供一种核电站用玻璃纤维水过滤纸及其制备方法，玻璃纤维水过滤纸的过滤精度≤0.45μm，SiO2的析出量＜0.8PPM，完全满足核电站一回路的水质要求。
为达到上述目的，本发明采取的技术方案是：
一种核电站用玻璃纤维水过滤纸，所述玻璃纤维水过滤纸由两种以上打浆度为39～60°SR硼硅酸盐玻璃微纤维棉和直径为0.3～2den、长度为5～10mm高性能有机纤维制成，所述高性能有机纤维所占的质量百分比为3～15％。
打浆工艺是在酸性助剂作用下将玻璃纤维切断并均匀分散形成玻璃纤维浆料悬浮液。采用两种打浆度的硼硅酸盐玻璃微纤维棉复配形成的纸页孔隙细密，过滤精度高。高性能有机纤维有较高的强度、韧性及抗SiO2析出性。二者交织在一起，形成纸页的强度和过滤精度高。
为了进一步提高所得纸页的强度及抗SiO2析出性，优选所述高性能有机纤维为聚酯纤维、芳纶纤维、聚醚砜纤维或超高分子量聚乙烯纤维中的一种或两种以上。
一种如上所述玻璃纤维水过滤纸的制备方法，包括如下步骤：
1)在硼硅酸盐玻璃微纤维棉和高性能有机纤维的混合物中加水及无机酸后均匀分散得到浆料；
2)将步骤1)所得浆料依次经除渣、稀释、成型、脱水后形成厚度均匀的湿纸页；
3)将步骤2)所得湿纸页依次施加絮凝剂、成膜剂、粘结剂，然后干燥形成玻璃纤维水过滤纸；
4)、将步骤3)所得的玻璃纤维水过滤纸的单面或者双面通过热压或冷压贴合无纺布。
玻璃纤维的主要成分是SiO2,玻璃由[SiO2]4网络结构结合成主体骨架,玻璃纤维直径越小,其比表面积越大,表面未断裂硅氧键和断裂的硅氧键十分巨大,表现为极易吸附水分子,在核电站水回路系统酸性介质中容易析出SiO2。絮凝剂中和玻璃纤维表面电荷，形成桥连作用，与成膜剂、粘结剂共同作用，增强玻璃纤维表面的SiO2结合，增强了抗微量元素浸出性，有效抑制SiO2的析出。
为了提高所得纸页的抗SiO2渗出性能，优选所述步骤3)中絮凝剂为聚二甲基二烯丙基氯化铵或聚合氯化铝中的至少一种，所得纸页中絮凝剂的质量百分比为0.1～2％。
为了提高所得纸页的抗SiO2渗出性能，优选所述步骤3)中成膜剂为聚醋酸乙烯酯、聚酯树脂、环氧树脂或聚氨酯中的一种或者两种以上，所得纸页中成膜剂的质量百分比为0.5～2％。
为了提高所得纸页的抗SiO2渗出性能，优选所述步骤3)中粘结剂为丙烯酸脂共聚乳液，所得纸页中粘结剂的质量百分比为2～8％。
为了进一步提高所得纸页在酸性介质中的抗SiO2析出性，优先所述步骤4)中无纺布为单组份无纺布或双组份无纺布，所述单组份无纺布为丙纶或涤纶中的一种，所述双组份无纺布为乙纶/丙纶或乙纶/涤纶中的一种。
本发明的有益效果：
1、通过采用两种以上打浆度的硼硅酸盐玻璃微纤维及高性能有机纤维复配，所得纸页的过滤精度高，过滤精度按NF X45-304-2000《滤芯-试验方法-绝对过滤精度的测定》可达0.45μm以下。
