Eminyakeni yamuva nje, imililo yezimoto zikagesi ibilokhu ivela ngokulandelana, ikakhulukazi emazingeni okushisa aphezulu ehlobo, izimoto zikagesi kulula ukuzithungela ngokuzenzakalelayo futhi zidale imililo!
Ngokusho kwethimba lesizwe le-alamu yokuhlenga umlilo lika-2021 kanye nedatha yomlilo ekhishwe yi-Fire Rescue Bureau yoMnyango Wezokuphathwa kwezimo eziphuthumayo, imililo ecishe ibe yi-18000 nokufa kwe-57 okubangelwa ukwehluleka kwamabhayisikili kagesi kanye namabhethri abo kwabikwa ezweni lonke ngonyaka odlule.Kubikwa ukuthi imililo yamabhayisikili kagesi engu-26 yenzeke eYantai esikhathini esingangesigamu sonyaka kulo nyaka.
Yini edala ukusha kwezimoto zikagesi kwenzeke njalo?
Icala eliyinhloko ngemuva kokushiswa okuzenzakalelayo kwezimoto zikagesi ukugijima okushisayo kwamabhethri e-lithium.Okubizwa ngokuthi i-thermal runaway ukusabela kweketango okubangelwa izikhuthazo ezihlukahlukene.Inani lekhalori lingakhuphula izinga lokushisa lebhethri ngezinkulungwane zamadigri, libangele ukusha okuzenzakalelayo.Amabhethri emoto kagesi athambekele ekubalekeni okushisayo ngenxa yokushajwa ngokweqile, ukubhoboza, izinga lokushisa eliphezulu, isifunda esifushane, umonakalo wamandla angaphandle nezinye izizathu.
Indlela yokuvimbela ngempumelelo ukubaleka okushisayo
Izindlela zokushisa ezingalawuleki zihlukahlukene.Ngakho-ke, izinyathelo eziningi zokuvimbela kufanele zithathwe ukuvimbela ukuvela kokushisa ngaphandle kokulawula.
Isizathu esiyinhloko se-thermal runaway "ukushisa".Ukuze uvimbele ngempumelelo ukubaleka okushisayo, kuyadingeka ukuqinisekisa ukuthi ibhethri ibisebenza ezingeni lokushisa elifanele.Kodwa-ke, ekushiseni okuphezulu ehlobo, "ukushisa" akunakugwenywa, ngakho-ke kudingeka siqale ngebhethri, ukuze senze ibhethri ye-lithium-ion ibe nokumelana nokushisa okungcono nokusebenza kokushisa kokushisa.
Okokuqala, abathengi badinga ukunaka izici ezifanele zamabhethri e-lithium lapho bethenga izimoto zikagesi, nokuthi ngabe izinto zangaphakathi zamaseli ebhethri zinokuphikiswa okuhle kokushisa nokusebenza kokushisa kokushisa.Okwesibili, kungakhathaliseki ukuthi isixhumi esixhunywe nebhethri ngaphakathi kwemoto kagesi sinokusebenza kokumelana nokushisa okuphezulu, kufanele siqinisekise ukuthi isixhumi ngeke sithambe futhi sihluleke ngenxa yokushisa okuphezulu, ukuze siqinisekise ukuthi isifunda asivinjiwe futhi sigweme ukwenzeka kwesikhashana. isifunda.
Njengochwepheshe bokuxhuma izimoto zikagesi, u-Amizimbongoloineminyaka engama-20 yocwaningo nesipiliyoni sokuthuthukiswa kuzixhumi zezimoto zikagesi ze-lithium, futhi inikeza izixazululo zamanje zokuxhuma ezithwalayo zamabhizinisi ezimoto zikagesi ezifana ne-Xinri, Emma, Y.i-adi, njll. Isixhumi semoto kagesi ekwazi ukumelana nokushisa okuphezulu kwe-Ames samukela i-PBT enokumelana nokushisa okuhle, ukumelana nesimo sezulu nezici zikagesi.Iphuzu elincibilikayo legobolondo lepulasitiki le-PBT elivikelayo lingu-225-235℃.
AmizimbongoloIlebhu
Izixhumi zezimoto zikagesi ezisezingeni eliphezulu ziphumelele uvivinyo lwebanga le-flame retardant, futhi ukusebenza kwe-flame retardant kufinyelela i-V0 flame retardant, engahlangabezana nezinga lokushisa le-ambient elingu -20 ℃ ~120 ℃.Ukuze isetshenziswe ngaphakathi kwebanga lokushisa elingenhla, igobolondo elikhulu lesixhumi semoto kagesi ngeke lithambe ngenxa yezinga lokushisa eliphezulu, libangele ukujikeleza okufushane.
Ngaphandle kokukhethwa kwamabhethri nezingxenye zawo, ikhwalithi yamashaja emoto kagesi, isikhathi eside sokushaja, ukuguqulwa okungekho emthethweni kwezimoto zikagesi, njll. kuyisihluthulelo sokuthuthukisa ukusebenza kokuphepha kwebhethri ye-lithium yemoto kagesi.
