Název v původním jazyce

Application of nanofibres in filtration processes in FPS2010 - Europian Conference on Fluid-Particle Separation

Popis výsledku v původním jazyce

Mechanisms of capture of dust particles, two- and three dimensional modelling of properties of filtrationmaterials and effect of selected variables on electrospinning of polyurethane (PU) solutions are discussedwith the aim to prepare a nanofibre structure capable of capturing ultrafine particles. The two-dimensionalmodelling is used to gain an idea of the effect of mass per square area, thickness of nanofibre layers andnanofibre diameter on filtration efficiency of ultrafine particles. Values of filtration efficiency calculated at thethree-dimensional modelling of the filtration process are compared with experimental measurements. The most important characteristics affecting quality of nanofibre materials are nanofibre diameter, porosity and homogeneity of nanofibre layers. The methodmaking possible to achieve the required diameter of the nanofibres is demonstrated on the influence ofrelative humidity and solvent type on the fibre-forming process taking place in an electrostatic field
