Shenhai Explosion-Proof
Tawg-Proof Classification
| 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 |
Hoob Kawm Kuv: Hluav taws xob khoom tsim siv nyob rau hauv underground thee mines;
Hoob Kawm II: Hluav taws xob khoom siv nyob rau hauv tej chaw explosive roj, excluding thee mines thiab underground teev;
Hoob kawm II faib ua IIA, IIB, thiab IIC. Li no labeled li IIB yog suitable rau tej chaw uas IIA li siv; IIC li yuav tau utilized rau cov neeg mob tsim nyog rau ob IIA thiab IIB khoom.
Distinctions ntawm ExdIICT4 thiab ExdIIBT4
Lawv cater txawv pawg gases.
Ethylene Yog cov roj uas muaj tus kab mob BT4.
hydrogen thiab acetylene yog cov gases rau CT4.
Cov khoom nyob CT4 surpass cov neeg nyob BT4 hauv specifications, Raws li CT4 li yuav utilized nyob rau tej cheeb tsam suitable rau BT4, whereas BT4 li no tsis muaj feem xyuam rau tej cheeb tsam tsim nyog rau CT4.
