Surface| Zusammenfassung: | The influence have been studied of UV photoozonization on the wetting value of polypropylene microfibrous material used as a part of the filter for water and aqueous solutions. The wetting value has been found to change nonmonotonically as dependent on the time of photoozonization. Such a dependence is connected with prevalence of one process in time interval: generation of oxygen-containing products or their decomposition to oxygen-free hydrophobic compounds. The productivity of filtration has been studied as dependent on the UVO treatment time. The highest productivity of filtration has been found to take place under short terms of treatment of the filters made from polypropylene microfibrous fabrics. |
