Shenhai Explosion-Ubungqina
Ukongeza kwi-classification-proof classifications, Izibane ze-LED ezinobungqina bokudubula nazo zibekwe kwinqanaba lokulwa nokubola kwazo. Izibizo ezinobungqina bokudubula ziwela ngokubanzi kwiindidi ezimbini: IIB kunye ne-IIC. Uninzi lwezibane ze-LED zihlangabezana nomgangatho ongqongqo we-IIC.
Ngokumalunga ne-anti-corrosion, Iireyithingi zicatshulwe kabini kwimo engqongileyo yangaphakathi kunye namanqanaba amathathu okusetha ngaphandle. Amanqanaba e-anti-corrosion yangaphakathi aquka i-F1 ephakathi kunye ne-F2 yokumelana okuphezulu. Ngeemeko zangaphandle, ulwahlulo lu-W lokumelana nokubola kokukhanya, WF1 yemodareyitha, kunye ne-WF2 yokuxhathisa okuphezulu kwe-corrosion.
Olu lwahlulo luneenkcukacha luqinisekisa ukuba izixhobo zokukhanyisa zilungelelaniswe neemeko ezithile zokusingqongileyo, ukwandisa zombini ukhuseleko kunye nokuphila ixesha elide.
