| titleOfInvention | Manufacturing method of enhanced polytetrafluoroethylene for high-medium pressure valve sealing element |
| abstract | The invention relates to a method for manufacturing enhanced polytetrafluoroethylene for a high-medium pressure valve sealing element, which comprises the following steps: mixing the raw materials; forming an inner blank: putting the inner material into a small mold, compacting and molding at the molding pressure of 18-20MPa to obtain a rough inner blank; primary firing of an inner blank: placing the rough inner blank into a sintering furnace for sintering and forming, and then naturally cooling to room temperature; forming an outer blank: coating an adhesive on the surface of the fired inner blank, then putting the rough inner blank into a large mold, putting the outer material into the large mold, and forming under the pressure of 34-39MPa to obtain a rough final blank; final firing: placing the rough finished blank into a sintering furnace for sintering and forming, and then naturally cooling to room temperature to obtain a product to be detected; and (6) detecting. The sealing element prepared by the invention has good rigidity in the interior and certain flexibility of the sealing surface, so that the sealing element has good strength, the service life of the sealing element is prolonged, and meanwhile, the sealing element can have good sealing effect. |
