Shenhai Explosion-Proof
Cov sawv cev rau cov tswvyim kiag li.
| Qeb | Roj Classification | Cov neeg sawv cev gases | Yam tsawg kawg yog Ignition spark zog |
|---|---|---|---|
| Nyob rau hauv lub mine | Kuv | methane | 0.280mJ |
| Factories sab nraum lub Mine | IIA | Propane | 0.180mJ |
| IIB | Ethylene | 0.060mJ | |
| IIC | hydrogen | 0.019mJ |
IIC feem ntau yog raug tus kab mob explosion-proof tej chaw, Characterized los ntawm tej yam xws li hydrogen thiab ethyl nitrate. Conversely, IIIC, txhais los ntawm lub teb chaws qauv, pertains los tsim plua plav explosions, tsim raws li DIP A21. IIIA npog qhov khuv fibers, thiab IIIB encompasses non-conductive plua plav.
IIC yuav tsis interchangeable nrog IIIC; yog li ntawd, t, Cov khoom uas muaj plua plav tawg-pov thawj ntsuam xyuas xws li DIP A20/A21 yuav tsum tau xaiv.
