Description

一种袋式除尘器高强度滤料
技术领域
本发明涉及一种滤料，尤其涉及一种袋式除尘器高强度滤料。
背景技术
玄武岩纤维是采用单组份矿物原料熔制而成的一种高性能无机纤维，外表呈光滑的圆柱状，其截面呈完整的圆形。玄武岩连续纤维具有较高的拉伸强度、耐高温，弹性模量高，优异的耐化学腐蚀性能等优点。
PPS纤维比起常规纤维具有更优良的耐热性和热稳定性。它在高温下具有优良的强度、刚性及耐疲劳性，可在200~240℃下连续使用，在低于400℃的空气或氮气中较稳定，基本无重量损失。其耐化学腐蚀性与号称“塑料之王”的聚四氟乙烯（PTFE）相近，能抵抗酸、碱、氯烃、烃类、酮、醇、醋等化学品的侵蚀，在200℃下不溶于任何化学溶剂。同时具有优异的阻燃性能，限氧指数（LOI）为34%，在火焰上能燃烧，但不会滴落，且离火自熄，发烟率低于卤化聚合物。
目前对于袋式除尘器中的过滤，主要采用玻璃纤维、芳香族聚酰胺纤维（芳纶）、聚酰亚胺纤维（P84）等纤维制成的过滤材料，不同程度的存在着过滤材料被腐蚀、过滤精度低、使用寿命短等问题，已经不能充分满足过滤的要求。
发明内容
本发明的目的就在于为了解决上述问题而提供一种拉伸断裂强度高，过滤效率高，同时耐高温性、耐腐蚀性、耐折性、耐磨性好，寿命长的袋式除尘器高强度滤料。
为了实现上述目的，本发明是通过以下技术方案实现的：一种袋式除尘器高强度滤料，它包括迎尘面以及净气面；所述迎尘面采用连续玄武石纤维材料层，其纤维直径为10-30μm，体积密度为0.20-0.35g/m3；所述净气面采用PPS纤维材料层，其纤维直径为15-45μm，体积密度为0.50-0.65g/m3。
进一步的，所述迎尘面与净气面之间通过高温热压粘合在一起；所述高温热压的温度为400-500度，压力为1.5-1.7MPa。
再进一步的，所述迎尘面与净气面在高温热压粘合之前还进行热清洗处理；所述热清洗处理的温度为200-300度。
本发明的有益效果是：本发明通过高温热压将迎尘面与净气面粘合在一起，同时在高温热压之前进行热清洗处理，有效的去除纤维表面的残留物，保证滤料强力不受损；本发明滤料拉伸断裂强度高，过滤效率高，同时耐高温性、耐腐蚀性、耐折性、耐磨性好，寿命长。
