Qhov twg theem ntawm Explosion-Proof yog siab dua, CT2 los yog CT4

Nws yog pov thawj tias CT4 tuav qhov kev ntsuam xyuas tawg ntau dua. Qhov tseem ceeb, Kev tawg-pov thawj lub cev muaj zog muaj cov npe IICT4 tab sis tsis muaj qhov cim IICT2.

Qhov kub thiab txias IEC / EN / GB 3836	Qhov siab tshaj qhov kub ntawm cov khoom siv T [℃]	Lgnition kub ntawm cov khoom combustible [℃]
T1	450	T 450
T2	300	450≥ T 300
T3	200	300≥ T 200
T4	135	200≥T ＞ 135
T5	100	135≥T 100
T6	85	100≥T8

Qhov kev sib txawv no tshwm sim los ntawm qhov ntsuas kub ntawm cov khoom siv hluav taws xob tawg: T4 cov cuab yeej tsim los tswj qhov kub siab tshaj plaws hauv qab 135 ° C, whereas T2 li tso cai rau qhov kub siab tshaj plaws saum npoo mus txog 300 ° C, suav tias txaus ntshai heev.

Yog li ntawd, CT4 yog qhov kev xaiv zoo tshaj plaws; CT2 feem ntau yog zam.
