| titleOfInvention | Preparation method of fluorescence method dissolved oxygen sensor diaphragm |
| abstract | The invention discloses a preparation method of a fluorescence-method dissolved oxygen sensor diaphragm, which comprises the steps of uniformly mixing tetraethoxysilane, methyltriethoxysilane, dimethyldimethoxysilane, absolute ethyl alcohol and hydrochloric acid solution, stirring at room temperature for 15-30min, heating to 60-80 ℃, keeping the temperature and stirring for 18-26h to obtain siloxane sol solution, then mixing the siloxane sol solution and the absolute ethyl alcohol solution, adding a fluorescence indicator, and stirring in the dark at 15-25 ℃ until the siloxane sol solution and the absolute ethyl alcohol solution are completely dissolved to obtain the fluorescence sol solution. The invention uses the high-temperature spraying technology to spray the fluorescent sol on the substrate, controls the spraying range and thickness, and obtains the fluorescence-method dissolved oxygen sensor membrane with uniform thickness. |
