Kwiminyaka yakutshanje, imililo yemoto yombane iye yavela enye emva kwenye, ngakumbi kwiqondo lokushisa eliphezulu ehlotyeni, izithuthi zombane zilula ukuba zivutha ngokuzenzekelayo kwaye zibangele umlilo!
Ngokutsho kwe-2021 yeqela lesizwe lokuhlangula i-alarm ye-alarm kunye nedatha yomlilo ekhutshwe yi-Fire Rescue Bureau ye-Ofisi yoLawulo lwezongxamiseko, phantse umlilo we-18000 kunye nokufa kwe-57 okubangelwa ukungaphumeleli kweebhayisikili zombane kunye neebhetri zabo zichazwe kulo lonke ilizwe kunyaka odlulileyo.Kuxelwe ukuba imililo yebhayisekile yombane engama-26 yenzeke eYantai kwisiqingatha nje sonyaka kulo nyaka.
Yintoni ebangela ukuba imililo yemoto yombane yenzeke rhoqo?
Icala eliphambili emva kokutshiswa ngokuzenzekelayo kwezithuthi zombane kukubaleka kwe-thermal yeebhetri ze-lithium.Oku kubizwa ngokuba yi-thermal runaway yintshukumo yetsheyini ebangelwa ziinkuthazo ezahlukeneyo.Ixabiso le-calorific linokunyusa ubushushu bebhetri ngamawaka amadigri, okubangela ukutsha okuzenzekelayo.Iibhetri zeemoto zombane zixhomekeke ekubalekeni kwe-thermal ngenxa yokugqithiswa, ukubhoboza, ukushisa okuphezulu, isiphaluka esifutshane, umonakalo wangaphandle kunye nezinye izizathu.
Indlela yokuthintela ngokufanelekileyo ukubaleka kwe-thermal
Izinto ezibangela ubushushu obungalawulekiyo zahlukene.Ngoko ke, amanyathelo amaninzi okukhusela kufuneka athathwe ukukhusela ukwenzeka kobushushu ngaphandle kolawulo.
Eyona nto ibangela ukubaleka kwe-thermal "bubushushu".Ukuthintela ngokufanelekileyo ukubaleka kwe-thermal, kuyimfuneko ukuqinisekisa ukuba ibhetri ibisebenza kwiqondo lokushisa elifanelekileyo.Nangona kunjalo, kwiqondo lokushisa eliphezulu ehlotyeni, "ubushushu" abunakuphepheka, ngoko kufuneka siqale ngebhetri, ukwenzela ukuba ibhetri ye-lithium-ion ibe nokumelana nokushisa okungcono kunye nokusebenza kokushisa.
Okokuqala, abathengi kufuneka banikele ingqalelo kwiimpawu ezifanelekileyo zeebhetri ze-lithium xa kuthengwa izithuthi zombane, kunye nokuba izinto zangaphakathi zeeseli zebhetri zinokumelana nokushisa okulungileyo kunye nokusebenza kokushisa.Okwesibini, nokuba isinxibelelanisi esidityaniswe nebhetri ngaphakathi kwisithuthi sombane sinomsebenzi wokumelana nobushushu obuphezulu, kufuneka siqinisekise ukuba isinxibelelanisi asiyi kuthamba kwaye asiyi kuphumelela ngenxa yobushushu obuphezulu, ukuze kuqinisekiswe ukuba isekethe ayivalwanga kwaye iphephe ukwenzeka kokufutshane. isiphaluka.
Njengengcali yobuchwephesha bokudibanisa isithuthi sombane, u-Amiimpunduuneminyaka engama-20 yophando kunye namava ophuhliso kwizixhumi zezithuthi zombane ze-lithium, kwaye ibonelela ngezisombululo zoqhagamshelo lwangoku lwamashishini ombane afana neXinri, Emma, Y.i-adi, njl njl. Isidibanisi se-Ames isithuthi sombane esinganyangekiyo sithatha i-PBT enokumelana nokushisa okulungileyo, ukumelana nemozulu kunye neempawu zombane.Indawo yokunyibilika ye-PBT yokukhusela igobolondo leplastiki yi-225-235℃.

Iziqhagamshelo zeenqwelo zombane ezinobushushu obuphezulu ziye zaphumelela uvavanyo lwebanga lokungatshatyalaliswa komlilo, kwaye ukusebenza kwe-flame retardant kufikelela kwi-V0 flame retardant, enokuthi ihlangabezane nobushushu be-ambient -20 ℃ ~ 120 ℃.Ukusetyenziswa ngaphakathi kolu luhlu lweqondo lokushisa elingasentla, igobolondo eliphambili lesiqhagamshelo sesithuthi sombane aliyi kuthamba ngenxa yobushushu obuphezulu, kubangele isiphaluka esifutshane.
Ukongeza ekukhethweni kweebhetri kunye namacandelo abo, umgangatho weetshaja zezithuthi zombane, ixesha elide lokutshaja, ukuguqulwa ngokungekho mthethweni kwezithuthi zombane, njl.
