膜裂切割法制备聚四氟乙烯长纤维,再经过加捻、整经和织造等工艺制备高性能聚四氟乙烯纤维网布。检测结果表面:聚四氟乙烯纤维网布具有良好的力学性能,并且具有优异的耐酸耐碱和耐水解性能。聚四氟乙烯长纤维经过进一步深加工之后,在氯碱工程中的离子交换膜和高温除尘用覆膜滤料等方面具有较广泛的应用。
Membrane cleavage Preparation of long fibers of PTFE, and then after twisting, warping and weaving and other technology preparation of high-performance PTFE fiber mesh. Test results surface: Teflon mesh has good mechanical properties, and has excellent acid and alkali resistance and hydrolysis resistance. Teflon long fiber after further processing, the chlor-alkali engineering in the ion exchange membrane and high temperature dust with a filter membrane and other aspects of a wider range of applications.
