| titleOfInvention | A sealant composition for on-line test leakage of fluorine gas pipeline and preparation method thereof |
| abstract | The invention relates to the field of new materials, in particular to a sealant composition for on-line leakage testing of fluorine gas pipelines and a preparation method thereof; the composition comprises the following mass proportions: polytetrafluoroethylene powder 80%-90%, iodine Chemical powder 2.5%-5%, calcium fluoride powder 5%-8%, air oxidation inhibitor 0.5%-3%, additives 2%-4%. The present invention adds calcium fluoride, iodide, etc. to the fluoroplastic polytetrafluoroethylene. When fluorine gas leaks on the sealing surface, the fluorine gas can oxidize the iodine ion layer to make the sealing material appear red, and the leakage problem can be found in time. and locate the leak. In addition, in order to prevent iodide from being oxidized by the air to generate iodine and cause misjudgment, the present invention adds an air oxidation inhibitor to the formula, which can also provide an alkaline environment to inhibit the oxidation of iodide ions and prevent misjudgment; The material used for air duct sealing also has the function of leak detection. |
