Description

technical field [0001] The invention relates to the technical field of fiber filter membrane preparation, in particular to a fiber filter membrane preparation device and a preparation method thereof. Background technique [0002] Fiber filtration membranes play an important role in the fields of filtration, catalysis, medicine and biology. Nanofibers have the characteristics of large specific surface area, good strength and stiffness, easy dispersion, and good processing performance, which reflect excellent filtration characteristics and can be effectively Filter micro-nano particles. [0003] When the porous structure appears on the fiber membrane, its surface area, porosity, surface activity and adsorption performance are further improved. Therefore, the porous nanofibrous membrane has greater application space and potential. In addition, the filter membrane with low filtration resistance can effectively reduce the filtration driving force, improve the filtration efficien...
