Preparation of Titanium Microfiltration Membrane by Field–Flow Fractionation Deposition

The primary aim pursued by the preparation of the separation membrane is to make the membrane thinner as well as have no defects. The field-flow fractionation deposition is a new molding technology which can overcome the traditional disadvantages, such as multi-preparation, to the preparation of a great area of the separation membrane with no defects. Therefore the main ingredients which influence the appearance and performance of titanium membrane layers are investigated by a scanning electricity mirror (SEM) as well as a porous material testing instrument: powder performance prepared and confected; selection of supporting body; sintering system such as temperature and time. It is shown that the membrane thickness can be controlled at 50μm or so.
