Izehlakalo zakamuva iSamsung eye yaba nazo ngeGalaxy Note 7, njengoba wazi kahle, zidale ukuthi inkampani imemezele isinqumo zisuse ngokushesha emaketheAzenzi lutho kepha zigxila kumabhethri kulawa ma-terminals. Manje kuyiqiniso lokho Qaphela amabhethri ayi-7 akuwona kuphela aqhuma ezimweni ezithile futhi i-Samsung akuyona kuphela umkhiqizi osebenzisa amabhethri afakwe kumatheminali ayo.
Enye yezinkinga ezinkulu ezibhekene nabakhiqizi namuhla kungaba kuzo ukuntuleka kokubona kusengaphambili nokutshalwa kwezimali ekwakheni amabhethri. Kuleli qophelo ngithanda ukuma ngigqamise ukuthi, ngokwesibonelo, ijubane labaprosesa liphindaphindeka kanjani unyaka nonyaka ngenkathi amabhethri, ukwakhiwa kwawo, umthamo ... singasho ukuthi sekuphindwe kabili kule minyaka eyishumi edlule. EMpumalanga ukungalingani ekuthuthukisweni kobuchwepheshe yikhona okubangela zonke lezi zinkinga.
Ngabe isebenza kanjani ibhethri?
Ukuqonda kangcono konke okwenzekayo, kungcono ukuqala ngokuqonda ukuthi ibhethri liyini. Ukwenza lula inkolelo-mbono kakhulu, ibhethri namuhla kuseseyi- isitsha samandla amakhemikhali. Lapho sixhuma, isibonelo, i-smartphone yethu kunethiwekhi kagesi, ngaphakathi kwebhethri ukusabela kwamakhemikhali kuqala lapho kudluliswa khona ama-electron kusuka esigxotsheni esihle sebhethri kuya esigxotsheni esibi. Uma usukhokhisiwe, idivayisi inganikwa amandla kuze kube, futhi, wonke ama-electron adlulisiwe.
Ngenxa yendlela yayo elula yokusebenza, sithola umkhawulo wayo wokuqala kusukela, ibhethri lingakhiqiza ugesi omningi ngendlela amandla angagcina ngayo izingxenye zalo zamakhemikhali. Ngakolunye uhlangothi, amabhethri awahlali ngendlela ebesingathanda ngayo futhi lokhu kungenxa yokuthi, ngokuhamba kwesikhathi, ukusabela kwamakhemikhali okuzokhiqizwa kuye kuvikeleke kakhulu futhi lapho ukumelana kukhula, kuba nzima kakhulu ukugcina ukungezwani okungapheli, ngaleyo ndlela kuncishiswe amandla angakhiqizwa.
Kungani kuqhuma ibhethri?
Uma sesicacise konke okungenhla, sekuyisikhathi sokuphendula umbuzo wokuthi kungani liqhuma ibhethri? Ngokuya ngemibono ye- UBilly Wi, USolwazi Wezobunjiniyela e-Imperial College London:
Uma ufaka amandla amaningi ebhokisini, kuzoba yingozi kakhulu. Ukuphathwa kwe-Thermal kubalulekile. Uma ibhethri lifudunyelelwa ngaphezu kwama-degree angama-80 likhiqiza lokho okubizwa ngokuthi yi-thermal runaway, lapho izingxenye ziqala ukonakala nokuyilapho ingaqhuma khona.
Kumele kukhunjulwe ukuthi, kuze kube yilapho ubuchwepheshe obuthile bufanelekile ukukhiqiza amabhethri amadivayisi, ukufeza ukuthi ukusebenza kwawo kuyefana nokwamanje nokuthi amanani abo awaphakeme, Abaphenyi bazoqhubeka nokusebenza ukuletha ukusebenza kwamabhethri amanje eduze nemikhawulo yabo yethiyori.
Ukwaziswa okwengeziwe: umgcini
Esokuqala asiqhumanga, kunomehluko omkhulu kakhulu phakathi kokuqhuma nomlilo. Noma phakathi kokuthumela okuthile okunolwazi noma ukukopisha nokunamathisela.
