Shenhai Explosion-Proof
Lub ignition kub ntawm ib explosive roj mixture nruab nrab yog qhov kub tshaj plaws uas nws yuav tau ignited.
Explosion-proof lighting khoom yog categorized rau hauv pawg T1 rau T6, Raws li qhov kub tshaj plaws ntawm lawv cov casing casing. Qhov kev kawm no yuav xyuas kom meej tias Qhov kub tshaj plaws ntawm lub explosion-proof teeb khoom nyob rau hauv txhua pab pawg neeg tsis tshaj qhov permissible kub rau ntawd qeb qeb. Txoj kev sib raug zoo ntawm txoj kev sib raug zoo txias pawg, qhov kub ntawm cov khoom, thiab cov ignition kub ntawm flammable gases los yog vapors yog illustrated hauv lub accompanying diagram.
| Kub IEC/EN/GB3836 | Qhov kub ntawm tus ntaus ntawv [°C] | Igniting kub ntawm combustible tej yam khoom [°C] | Combustible tej yam khoom |
|---|---|---|---|
| T1 | 450 | T>450 | 46 hydrogen, acrylonitrile, thiab lwm yam |
| T2 | 300 | 450≥T>300 | 47 hom acetylene, ethylene, thiab lwm yam |
| T3 | 200 | 300≥T>200 | 36 roj av, butyraldehyde, thiab lwm yam |
| T4 | 135 | 200≥T>135 | |
| T5 | 100 | 135≥T>100 | Carbon disulfide |
| T6 | 85 | 100≥T>85 | Ethyl nitrate |
Nws yog tshwm tag los ntawm qhov no tias sab qhov kub ntawm lub casing, qhov kev ruaj ntseg ntau dua, Ua T6 qhov kev ruaj ntseg thiab T1 qhov riskiest ntawd tej ignition hazards.
