Shenhai Explosion-Proof
Cov bt4 ntsuam xyuas rau explosion-proof khoom qhia ob tug thawj parameters. txuas ntxiv, ' b’ Nyob rau hauv bt4 denotes Hoob Kawm IIb, signifying nws siv nyob rau hauv cov-tsuas teev.

B
'B’ qhia cov roj theem nyob rau hauv ib cheeb tsam, txiav txim tau los ntawm kev siv theem. No classification feem ntau nyiaj rau qhov ntau kis los ntawm cov gases yuav kis tau thiab lawv yam tsawg kawg yog ignition tam sim no. Nws yog categorized rau peb theem: Hoob Kawm A, B, thiab C. Ib cheeb tsam muaj kev ruaj ntseg zoo, Hoob Kawm B muaj ntau hazardous, thiab Hoob Kawm C yog ib yam txaus ntshai, tab sis yog tsawg dua. Hoob Kawm C tawg-proof khoom muaj feem xyuam rau ob hoob kawm A thiab B ib puag ncig, Hoob Kawm B cov khoom siv yog suited rau hoob kawm A teev, thiab Hoob Kawm A yog exclusively rau hoob kawm A ib puag ncig. Vim li ntawd, Hoob kawm B yog feem ntau cov txheej txheem rau explosion-proof khoom nyob rau hauv lub lag luam. Tus hierarchy ntawm cov hoob kawm no hoob kawm C > Hoob Kawm B > Hoob Kawm A.
T4
T4 denotes lub txias hoob kawm nyob rau hauv ib cheeb tsam, raws li cov gases’ Kwv tij ignition ntsiab lus. Muaj peevxwm classifications necessitate txo kev khiav hauj lwm kub thiab ntau stringent khoom specifications. Cov classifications no tailored rau cov qauv kawm ntau lawm, Yuav tsum tau xaiv cov khoom tawg-pov thawj los phim lub peevxwm kub. T4-rated khoom yog tsim los khiav lag luam ntawm qhov kub xws li 135 mus rau 200°C.
Cov bt4 tawg-pov thawj ntsuam xyuas yog cov prevalent feem ntau, Muab nws kim heev thiab xaiv ib sab xaiv uas muaj feem xyuam rau tej chaw.
