CONTOURED LAYER CHANNEL FLOW FILTRATION MEDIA |
摘要 |
<p>A method of forming a contoured layer channel flow filtration media is provided, whereby first a contoured polymeric film layer is formed, then the contoured film layer is joined to a second polymeric layer at at least one face of the contoured film layer, so as to stabilize the contoured film layer and form flow channels and finally the flow channel assembly of the contoured film layer and the second layer are electrostatically charged. The flow channel layer assembly can be layered so as to create a filtration media array having multiple flow channel layers and then said filtration media array can be sliced with a hot wire so as to fuse the adjacent layers. <IMAGE></p> |
