Shenhai tawg-pov thawj
Feem ntau, Kev faib pov thawj tawg rau cov cheeb tsam hydrogen yog qib IIC. Rau cov khoom siv ntsuas T1, Qhov kub ntawm qhov chaw siab tshaj plaws yog qis dua 450 ° C. Muab hais tias hydrogen lub ignition kub nce mus txog 574 ° C, xaiv rau T1 yog txaus.
| Kub pawg ntawm cov khoom siv hluav taws xob | Qhov siab tshaj plaws qhov kub thiab txias ntawm cov khoom siv hluav taws xob (℃) | Gas / vapor ignition kub (℃) | Qhov ntsuas kub ntawm cov cuab yeej siv tau |
|---|---|---|---|
| T1 | 450 | 450 | T1 ~ T6 |
| T2 | 300 | ＞ 300 | T2 ~ T6 |
| T3 | 200 | 200 | T3 ~ T6 |
| T4 | 135 | 135 | T4 ~ T6 |
| T5 | 100 | ＞ 100 | T5 ~ T6 |
| T6 | 85 | 85; ib | T6 |
Ua cov qib qis tshaj hauv kub kev faib tawm, ib qho T-rating ua tau raws li cov qauv. Li no, hauv hydrogen Kev ntsuas tawg-pov thawj, ob qho tib si CT1 thiab CT4 yog cov kev xaiv siv tau, nrog CT1 cov cuab yeej feem ntau ua tau zoo dua.
