| Abstract: |
| Objective To research the igniter on its ignition pressure changing with the storage time and area. Methods The igniter stored in the north and south area under normal conditions for 5, 10, 15, 19 years was tested for ignition pressure-time relation. Results The ignition pressure first increased and then decreased with the increase of time. The max pressure of the igniter which stored in the north declined about 0.4 MPa; that stored in the south decreased about 0.3 MPa. But the pressure time of the igniter stored in the north was longer than that stored in the south. Conclusion The ignition pressure changes with the storage time and the area, but the variation is allowed. Regional different has certain influences on performance of igniter. Temperature is one of the main factors. |
