A kind of preparation method of dust removal and VOCS synergistic photocatalytic filter material and prepared filter material |
| abstract |
The invention discloses a preparation method of a dedusting and VOCS synergistic photocatalytic filter material, comprising the following steps: (1) preparation of silver nitrate solution; (2) preparation of sodium dihydrogen phosphate/PTFE composite film-forming dipping solution; (3) Preparation of needled felt; (4) first-step treatment of filter material; (5) second-step treatment of filter material. The present invention adopts Ag 3 PO 4 as the photocatalyst, firstly immersing the PTFE needle-punched filter material in the silver nitrate solution to make it fully immersed and fully absorbed, and then placing it in the composite emulsion of PTFE and sodium dihydrogen phosphate. The silver nitrate in the PTFE filter material will react with the sodium dihydrogen phosphate in the composite emulsion in-situ precipitation reaction to generate a silver phosphate photocatalyst. The Ag 3 PO 4 photocatalyst can be evenly distributed on the filter material, while the Ag 3 PO 4 itself has It has good photocatalytic performance, and has good photocatalytic performance under visible light and ultraviolet light, which can effectively oxidize and reduce organic pollutants into water and carbon dioxide. |
