进一步地,所述步骤(1)中所述无碱玻璃纤维是单丝直径为3.5-5.5μm的E级玻璃纤维纱。
进一步地,所述步骤(1)具体是将玻璃纤维有捻及无捻纱经空气变形机蓬松、整经、掏综,再采用凸轮剑杆织布机和喷气式织布机按照需要的织物组织结构进行织造,所述织物组织结构包括一上三下斜纹、五枚三飞纬二重缎纹或斜纹纬二重。
进一步地,所述步骤(2)热清洗是将过滤材料置于经热风炉烘干的竖炉中,经导布辊往复储布30m,在500-550℃下进行热清洗。

进一步地,所述步骤(4)具体是将水洗后的玻璃纤维过滤材料经30m高的经热风炉烘干的竖炉储布56m,在600-800℃的温度下进行烧结。
进一步地,所述步骤(5)的高锰酸钾溶液浓度为0.05mol/L-0.10mol/L,加热温度为65-85℃,氧化处理时间为20-30min。

(2)经热清洗把织造过程中的拉丝浸润剂及拼捻织造过程中的一切杂物清洗干净,使拉丝浸润剂的残留量达到0.02%以下,完全裸露的玻璃纤维过滤材料经酸沥滤处理液处理后,使其分相中易溶组分B203和Na2O等被酸沥滤出来,留下连续的SiO2的多孔骨架,再经600-800℃高温下烧结,使SiO2微孔闭合,恢复酸浸沥滤损失的强度,经酸沥滤、高锰酸钾氧化处理、再经化学浸润剂渗透浸渍,使玻璃纤维过滤材料完全被化学浸润剂包裹覆盖,完全改变了玻璃纤维过滤材料的整体性能,获得了高稳定性的氟硅氧超细改性纤维过滤材料;
(3)本发明制备方法生产的产品性能优良,化学稳定性好,耐温度从原始玻璃纤维过滤材料的280℃左右提高到了600℃以上,高强低延、耐磨、耐折及抗酸碱、耐腐蚀性能突出;
(4)本发明制备的产品广泛应用在钢铁、冶炼、水泥、燃煤锅炉、炭黑、电力等行业,使用寿命长、过滤粉尘精度高,能够在较苛刻的工况环境中长期使用,符合国家环境保护烟气、粉尘排放标准的严格控制,氟硅氧超细改性纤维过滤材料的收尘率可达到99.99%,粉尘排放5-20mg/N·m以下,在国内、国外发展前景十分广阔及巨大的市场潜力。
