摘要
玻纤/ePTFE高温热压覆膜滤料是耐高温滤料的发展方向,它是在经特殊配方表面处理的玻纤基布上复合ePTFE薄膜(膨化聚四氟乙烯薄膜)制成的新型过滤材料,它集中了玻璃纤维的耐高温、耐腐蚀、强度高、伸长低和PTFE薄膜的表面光滑,憎水透气,容易清灰、化学稳定性好等优良特性,是环境保护行业的更新换代产品。由于玻纤和ePTFE本身的特殊性质,要使二者能完美的复合在一起,就必须对它们分别进行改性处理。
     本文重点研究低温等离子处理和后续丙烯酸接枝改性对ePTFE薄膜表面性能的影响,整体按三步进行,首先探讨了采用不同等离子处理工艺对ePTFE薄膜表面性能的影响,分别使用了静态接触角测试、XPS、SEM、AFM以及T字剥离测试等测试手段对薄膜的亲水性和粘结性进行了分析,最后得出了等离子处理的最优化工艺条件。其次对经等离子处理后的薄膜,后续进行丙烯酸接枝改性以进一步提高和稳定薄膜表面的亲水性,同样采用以上的测试手段对薄膜的性能变化进行分析,最后得出最优化的丙烯酸接枝工艺条件。最后研究了不同热压复合工艺条件对覆膜滤料自身性能的影响,主要研究了对透气性和覆膜牢度的影响,考察了温度、压力以及张力对热压覆膜滤料的影响,采用正交设计的方法对实验测试结果进行分析,得出了热压复合的优化工艺。
     总结上诉研究结果,低温等离子处理对ePTFE薄膜的表面改性具有一定的时效性,并且改性效果不是很显著,因此对经等离子处理后的薄膜必须后续进行丙烯酸接枝,才能进一步提高和稳定ePTFE薄膜的表面改性效果。在热压复合工艺的研究中,发现张力对覆膜滤料的性能影响最大,其次是压力,最后是温度。因此在实际生产中必须对张力进行严格的控制,从而才能保证覆膜滤料的性能。
Glass Fiber/PTFE high-temperature hot-pressing membrane filter material is the development direction of the high temperature filter materials, which is a new filter material that on the surface of the glass fiber fabric composite PTFE film (porous PTFE film), which include the advantages of the glass fiber high temperature resistance, corrosion resistance, high strength, low elongation and the PTFE film surface is smooth, water-repellent, breathable, easy cleaning, and good chemical stability, so it is the upgrading product of the environmental protection industry. Because of Glass fiber and PTFE themselves'special nature, in order to make them together perfectly, them should be treated respectively.
     This paper focuses on low-temperature plasma processing and subsequent acrylic grafted to ePTFE membrane surface modification, influence on the performance of the whole at three, this paper firstly probes the plasma processing process to adopt different influence on the performance of the ePTFE membrane surface respectively, using the static contact Angle testing, XPS, SEM, AFM and T word stripping test means testing on film hydrophilicity and bonding was analyzed, it is concluded that the optimum process conditions plasma processing. Secondly by plasma processing after the film, the subsequent grafted on acrylic modified to further improve and stable membrane surface of hydrophilicity, also used above test means of the thin films performance analysis, finally come to change the optimization of acrylic grafted process conditions. Finally different hot-pressing process conditions on coated compound their influence on the performance of the filter material, mainly studies the permeability and the influence of coated fastness, inspects the temperature, pressure and tension on the influence of hot-pressing coated filter material, using the orthogonal design method to analyze the test results, it is concluded that the compound technology optimization hot-pressing.
     Summarize appeal research results, low-temperature plasma treatment on the surface modification of ePTFE film has certain timeliness and modification effect not significant, so by plasma processing after the film must follow-up for acrylic grafted, so as to further improve and stable ePTFE film effect of surface modification. In hot pressing the composite technique studies, found that tension on the performance of the filter material coated biggest influence, followed by pressure, finally is temperature. Therefore in practical production must undertake strict control of tension, in order to ensure the performance of coated filter material.
