Uas explosion-Proof theem yog yooj yim dua, BT4 LOS YOG CT6

Cov qauv BT4 yog classified nyob explosion-proof hoob kawm B nrog ib tug kub ntsuam xyuas ntawm T4, stipulating tias cov khoom kub tshaj 135°C.

Conversely, Tus qauv CT6 tuas ib hoob kawm C tawg-pov thawj ntsuam xyuas, Npog qhov uas yuav tsum tau BT4 thiab siv rau aav uas yus gases xws li hydrogen thiab acetylene. T6 khoom yuav tsum muaj ib qhov chaw kub tshaj 85°C.

Saib raws cov ntsiab lus ntawd txias pawg, T6 nruab nrab yog cov kev ruaj ntseg ntau tshaj, suggesting tias ib sab khoom kub yog preferable.

Vim li ntawd, CT6 possesses ib superior explosion-proof classification.
