Description
技术领域
[0001] 本发明属于烟气与粉尘治理的过滤材料领域，特别涉及一种金属丝网增强聚苯硫醚耐高温水刺滤料的制备方法。
背景技术
[0002] 滤料是袋式除尘器的核心，也是主要更换配件。目前，在钢铁、冶金、水泥、电力等行业使用的滤料多为针刺聚苯硫醚滤料，但是针刺机的钩针容易对纤维和基布造成损伤，影响基布与聚苯硫醚复合高温滤料的强度，严重降低产品的使用寿命。水刺法以高压、高密度水针代替机械钩针，最大限度地减少了对纤维和基布的损伤，同时避免出现针眼，孔径分布小且平均孔径更小，真正实现高效低阻的优异性能。但普通的耐高温水刺滤料的强力通常在1000N/5cm左右，在高阻力环境下长期运行易发生破损，严重影响滤料的使用寿命。在过滤材料中，基布是维持滤料三维结构和强力的基本组织结构，可靠的基布是滤袋正常使用的保障，高温过滤材料的强力主要是依靠于基布来提供。聚苯硫醚耐高温水刺滤料长期在高温环境下使用，基布在高温条件下的强力不足会使滤料的使用寿命显著缩短。
[0003] 为了克服耐高温水刺滤料上述缺陷，近年来人们进行大量试验或研宄，具体归纳如下:
[0004] 中国专利CN201120536079.1 “PPS与PTFE复合纤维增强水刺滤料”提供了一种PPS与PTFE复合纤维增强水刺滤料，该水刺滤料为层状结构，在PTFE增强基布的上下面分别对称粘贴复合纤维层。复合纤维层为PPS纤维与PTFE纤维按一定比例复合的复合纤维层，PTFE增强基布为PTFE机织布。其优点是耐酸性、碱性腐蚀性强；过滤精度高；使用寿命长。但PTFE机织布的成本较高，且水刺复合对PTFE基布的损伤较大，强力有所下降。
[0005] 中国专利CN201120306400.7 “一种工业窑炉用耐高温复合过滤材料”提供了一种工业窑炉用耐高温复合过滤材料，它呈矩形，它的截面包括玄武岩基布层，玄武岩基布层两侧分别设置第一 PPS纤网层和第二 PPS纤网层，第一 PPS纤网层、玄武岩基布层和第二 PPS纤网层通过水刺加工相互连接。其现有工业窑炉中使用的过滤材料相比，具有更好的耐热性，尤其适用于温度控制设备不完善、内部温度不稳定的中小型窑炉。但玄武岩基布的耐碱性略差，对滤料的使用工况提出了更高的要求。
[0006] 中国专利CN201120536115.4 “STEXF斯泰福水刺滤料”公开一种STEXF(斯泰福)水刺滤料，该水刺滤料为层状结构，在PPS在涤纶基布的上下面分别对称粘贴丝旦纤维层，丝旦纤维层由不同规格的丝旦纤维层组成，涤纶基布为涤纶高强低伸长丝基布。其优点是强度大幅提高；耐酸性、碱性腐蚀性、水解性强；过滤精度高、易清灰；运行阻力小，节省能源。但是由于涤纶的耐高温性能较差，滤料在高温条件下运行时强力迅速降低，严重影响滤料的使用寿命。
[0007] 中国专利CN201020659493.7 “玻璃纤维和聚苯硫醚纤维复合过滤水刺滤料”提供一种玻璃纤维和聚苯硫醚纤维复合过滤水刺滤料，在玻纤基布的两面采用水刺机对称粘贴玻纤与PPS复合的纤维面层。所述玻纤基布是一种膨体无碱玻纤纱线采用平纹织法制成的织物。玻纤基布为水刺滤料提供良好的强度，纤维面层采用玻纤和PPS混合，由于其PPS良好的耐温性能及抗酸性腐蚀性能，提高了滤料的使用寿命；同时玻纤和PPS均为高温材料，该水刺非织造布的使用温度为120-190°C，瞬间使用温度可达200°C。但玻纤耐碱性差，在碱性气体腐蚀下强力下降明显，影响滤料的正常使用。
[0008] 中国专利CN201120536053.7"PPS抗静电涂层水刺滤料”公开一种PPS抗静电涂层水刺滤料，该水刺滤料为层状结构，在PPS基布的上下面分别对称粘贴PPS抗静电纤维层，迎风面的PPS抗静电纤维层上设有聚四氟乙烯致密层，PPS抗静电纤维层为PPS纤维与不锈钢纤维按一定比例复合的三维纤维层。其优点是抗静电性能好，耐酸性、碱性腐蚀性强，过滤精度高、易清灰，使用寿命长。聚苯硫醚基布本身的强力较低，相对于常规PTFE基布、PPS基布、芳纶基布、玻纤基布等来说起始强力较低，长期在高阻力条件下使用容易破损，缩短使用寿命。
[0009] 综上所述，如何克服聚苯硫醚耐高温水刺滤料现有的缺陷，研发强力较高，在高温环境下仍能保持良好的强力保持率的滤料，仍是目前研宄的热点。目前尚没有专利对金属丝网增强聚苯硫醚耐高温水刺滤料进行研宄。
发明内容
[0010] 本发明所要解决的技术问题是提供一种金属丝网增强聚苯硫醚耐高温水刺滤料的制备方法，该方法生产成本低，得到的滤料不易破损、易清灰、不糊袋、不板结，且除尘系统压差小，延长滤袋使用寿命。
[0011] 本发明的一种金属丝网增强聚苯硫醚耐高温水刺滤料的制备方法，包括:
[0012] (I)聚苯硫醚纤维网的制备
[0013] 将经过抗静电剂整理过的聚苯硫醚纤维经过开松、混合、梳理、交叉铺网制得聚苯硫醚纤维网；
[0014] (2)聚苯硫醚水刺高温滤料坯体的制备:
[0015] 将金属丝平纹编织网作为中间层，与上述聚苯硫醚纤维网形成纤维层/中间层/纤维层的三层结构体，然后通过预针刺结合水刺加固，得到聚苯硫醚水刺高温滤料坯体；其中水刺加固由水刺-抽吸水反复六道工序组成，以消除滤料中滞留水的影响，形成平整、无明显水痕的滤料坯体；
[0016] (3)烧毛轧光:
[0017] 将上述聚苯硫醚水刺高温滤料坯体经烧毛轧光等后整理，得到洁净、平整、尺寸稳定的金属丝网增强聚苯硫醚耐高温水刺滤料。
[0018] 步骤(I)所述的交叉铺网是采用交叉折叠铺网机进行操作的。
[0019] 步骤(I)中所得到的聚苯硫醚纤维网的面密度为80〜200g/m2。
[0020] 步骤(2)中所述的金属丝平纹编织网，其规格具体为:面密度585〜643g/m2，目数10〜20目，纵向断裂强力1515〜2142N，横向断裂强力1509〜2117N，纵向断裂伸长率23〜26%，横向断裂伸长率24〜31%，厚度0.4〜0.7_，经玮密33〜78根/10cm。
[0021] 步骤(2)中所述的水刺加固中水刺的工艺参数具体为:水刺速度14m/min，水刺高度12mm，水刺压力40〜220bar。
[0022] 步骤(2)所得到的聚苯硫醚水刺高温滤料坯体的面密度为745〜1312g/m2，厚度为1.8〜3.1_，透气性为592〜1687mm/s，透气率偏差为1.8〜5.8%。
[0023] 本发明中的抗静电剂整理可以为:将烷基磷酸酯盐和烷基醚磷酸酯盐为主体的阴离子型抗静电剂稀释后以喷雾的形式均匀喷洒到聚苯硫醚纤维堆中，混合均匀。将加好抗静电剂的纤维密封平衡24h，使纤维变得平滑、柔和、潮湿，并具有良好的抱合性，以减少非织造生产设备高速运转时产生的静电对生产过程的影响。
[0024] 本发明得到金属丝网增强聚苯硫醚耐高温水刺滤料，经检测，面密度为745〜1312g/m2，厚度为0.9〜1.2mm,平均孔径31.47〜68.82um，透气率75〜1011mm/s，透气率CV值为6.4〜8.5% ;纵向断裂强力为1514〜2367N，断裂伸长率为25%〜30%，横向断裂强力为1573〜2781N，断裂伸长率为28%〜40% ;连续工作温度190°C下24h纵向断裂强力保持率在101%〜112%，横向断裂强力保持率在108%〜124%，经玮向热收缩率为0.4〜
1.4% ;瞬时工作温度190°C下纵向断裂强力保持率在100%〜110%，横向断裂强力保持率在106%〜115% ;经40%氢氧化钠常温处理24h后，纵向断裂强力保持率在100%〜107%，横向断裂强力保持率在101%〜106%。上述各项测试结果均达到或超出GB/T6719-2009《袋式除尘器技术要求》中耐温特性和专项技术要求所规定的指标。
[0025] 为解决聚苯硫醚耐高温水刺滤料现有技术所存在的强力较低、高温环境下强力保持率较低的缺点，本发明提供一种金属丝网增强聚苯硫醚耐高温水刺滤料的制备方法。本方法是采用以非织造技术制成聚苯硫醚纤维层；然后将纤维层对称附着在金属丝网的两面，经由预针刺和水刺加固(水刺加固由水刺-抽吸水反复6次组成)，得到表面平整、无明显滞留水痕的滤料；再经烧毛、乳光处理等技术方案，使滤料表面光滑平整并使滤料厚度得到有效控制，制得的滤料在瞬时工作温度190°C下的断裂强力保持率在100%以上，达到并超出GB/T6719-2009《袋式除尘器技术要求》中耐温特性所规定的指标(瞬时工作温度下断裂强力保持率多95%)，滤料不易破损，易清灰，不糊袋，不板结，且除尘系统压差小，延长滤袋使用寿命，可广泛应用于钢铁、发电、水泥、燃煤锅炉等高温烟气除尘过滤，生产成本低。
[0026] 有益效果
[0027] 本发明与现有技术相比，有以下优点:
[0028] (I)为了克服现有技术中水刺高温滤料初始强力较低的缺陷，本发明选用平纹编织不锈钢金属丝网基布，其强力高，无热收缩现象，尺寸稳定性好，在高温工况下常年应用，不会因高温而导致强力降低，延长了滤袋的使用寿命。所制得的水刺高温滤料纵向断裂强力为1514〜2367N，断裂伸长率为25%〜30%，横向断裂强力为1573〜2781N，断裂伸长率为28%〜40%，在较高的工作温度下滤料的强力也不会显著降低。经检测，本发明制得的滤料在连续工作温度190°C下24h的纵向断裂强力保持率在101%〜112%，横向断裂强力保持率在108%〜124%，经玮向热收缩率为0.4〜1.4%。瞬时工作温度190°C下纵向断裂强力保持率在100%〜110%，横向断裂强力保持率在106%〜115%，大大延长了滤袋的使用寿命。上述测试结果达到并超出GB/T6719-2009《袋式除尘器技术要求》中耐温特性所规定的指标(连续工作温度下24h断裂强力保持率彡100% ;瞬时工作温度下断裂强力保持率彡95%)。
[0029] (2)为了克服现有技术中刺针对聚苯硫醚纤维和基布损伤的缺陷，本发明采用预针刺加水刺的加固方式，水刺过滤介质有较高的透气率且与众多传统针刺或织物过滤介质相比具有相同甚至更好的过滤效率。水刺过滤介质可节省纤维10%〜15%，本发明采用的单层聚苯硫醚纤维层克重在80〜200g/m2之间，比传统过滤介质要轻很多，因此滤料成本显著降低。经检测，本发明制得的滤料所用纤网克重在160〜400g/m2之间，该滤料容易清灰，不板结，减小了除尘系统的压差，降低了除尘系统的运行成本，大大延长了滤料的使用寿命O
[0030] (3)为减小现有技术中高水刺压力下纤网表面滞留水的影响，本发明采用水刺-抽吸水反复六次的加工工艺，在每道水刺工序后都对滤料进行抽吸水，除去纤网表面产生滞留水，消除纤网表面产生褶皱现象，极大提高了纤网质量。
