Shenhai Explosion-Proof
Explosion-proof khoom yog categorized rau hauv ob hoob kawm:
Khoom siv rau siv nyob rau hauv underground thee mines.
Khoom siv nyob rau hauv tej chaw explosive roj uas tsis yog underground thee mines.
Tsis pub dhau lub qeb thib ob, Hoob kawm II tawg-proof khoom yog ntxiv faib raws li hom roj ib puag ncig nws yuav khiav lag luam hauv, IIA, IIB, thiab IIC. Cov IIC ntsuam xyuas nruab nrab yog qib siab uas muaj kev ruaj ntseg, kos npe tias khoom siv rau IIC yog suitable siv nyob rau hauv IIA, IIB, thiab IIC roj ib puag ncig.
Kev Kub Muaj Peevxwm:
T1 qhia ib qhov chaw ntau heev txias 450°C.
T2 denotes ib qhov kub tshaj plaws ntawm 300°C.
T3 nruab nrab yog ib qhov kub tshaj plaws ntawm 200°C.
T4 implies ib qhov chaw kub ntawm 135°C.
T5 qhia ib qhov kub tshaj plaws ntawm 100°C.
T6, Kev ruaj ntseg ntau tshaj plaws, denotes ib qhov kub tshaj plaws ntawm 85°C.
Qhov kev kawm no yuav xyuas kom meej tias cov khoom siv nyob rau hauv tej cheeb tsam uas tsim nyog raws li cov qauv tsim nyog rau cov neeg mob tam sim no.
