Explosion-Proof theem exd II BT4 txhais hais tias

Explosion-proof khoom txhua muaj ib qho explosion-proof ntsuam xyuas, Uas distinguishes qhov khoom ntawm explosion-proof tsim thiab muaj scenarios scenarios. Piv txwv, Tus tawg-prof ntsuam xyuas Exd IIB T4 yog piav nyob rau hauv qab no.

Ex: Tawg-profo kos.

d: Hom explosion-proof yog taws. Kuj muaj intrinsic kev ruaj ntseg hom ia, ib qho; muaj kev ruaj ntseg e; roj uas muaj roj; xuab zeb-filled q; encapsulated hom m; composite (Feem ntau siv nyob rau hauv explosion-proof tis thawv).

II: Refers rau ob qeb ntawm tawg-proof fais fab tuag. Cov qeb no tsim nyog rau explosive Roj tej chaw uas tsis yog thee mines (Hoob Kawm Kuv). Tseem hoob kawm III: Hluav taws xob khoom rau explosive tej chaw sab nraum thee mines. Hoob Kawm IIIA: Combustible fibers; Hoob Kawm IIIB: Plua plav uas tsis yog plua plav; Hoob Kawm III: Tsim kom muaj plua plav.

B: Hoob kawm IIB roj. Kuj muaj IIC thiab IIA. IIC yog qib siab, muaj feem xyuam rau IIA thiab IIB. IIB yog suitable rau IIA, tab sis tsawg dua tsis siv yooj yim dua.

T4: Qhov no txias Hoob kawm yog T4, Nrog rau cov khoom qhov kub tshaj plaws hauv qab 135°C.
