Fluorinated elastomeric gas diffuser membrane |
摘要 |
The present invention relates generally to a structure for a diffused aeration system. More particularly, the invention encompasses a diffuser membrane where at least a portion of the surface has been treated with at least one layer of fluorine, to form a fluorinated elastomeric gas diffuser membrane. The invention also includes the deposition of fluorine atoms on the surface of a non-fluorine containing membrane to create a permanent fluoro-elastomeric surface layer. Tubular and disc diffuser members are also disclosed that have at least a portion of them treated with at least one layer of fluorine. A process of making the inventive diffuser membrane is also disclosed. |
