Ukwembula Ikhemistri Ngemva Kwebhethri Lead-Acid
Wake wama ukuze ucabangisise ngezinqubo eziyinkimbinkimbi ezenzeka ngaphakathi kwemingcele eqinile yamabhethri aneasidi yomthofu? Ngaphakathi kwalezi zingqwembe eziphansi kukhona umdanso wamakhemikhali ophithizelayo, ohlela amandla esithembele kuwo. Ake singene enkingeni ezungeze impilo eyimfihlo ngaphakathi kwamabhethri e-lead-acid ngokusebenzisa ukuhlola kafushane.
Amapuleti omthofu Awenza Kanjani Ugesi Nge-Sulfuric Acid:
Ekujuleni kwamabhethri aneasidi yomthofu kuhlala uxhaxha lwamaseli, ngalinye lihlala ipheya lamapuleti - ama-electrode avumayo noma angalungile, ane-sulfuric acid ehlanjululwe esebenza njengesihlukanisi sawo. Uma ishajwe ngokugcwele, iseli ngalinye liletha cishe ama-volts angu-2.1. Ngebhethri engu-6-volt, amaseli amathathu ayadingeka, futhi ibhethri engu-12-volt, amaseli ayisithupha anele.
Amapuleti omthofu ngaphakathi kweseli ngalinye angamagridi aklanywe ngokuyinkimbinkimbi anenhlanganisela yamakhemikhali ehluke kancane, embozwe ngezinto ezisebenzayo ezihlukile. Njengoba ibhethri lisetshenziswa, liyaphuma, likhiphe amandla agciniwe futhi lidle izingxenye ze-sulfuric acid. Kancane kancane, i-sulfate evela ku-asidi imboza amapuleti, inciphise indawo ekhona ukuze ukusabela kwamakhemikhali kuqhubeke. Uma sekugcwele, ukusabela kuyama, okwenza ibhethri lingabi namandla.
Naphezu kokufinyelela kuleli qophelo, kunethemba lokuvuswa kwamabhethri e-lead-acid ngokushajwa kabusha. Lapho ishajwa kabusha, i-sulfate ibuyela ku-asidi, okuvumela inqubo ukuthi iqale kabusha. Kodwa-ke, akuwona wonke i-sulfate ebuyiselwa ngokugcwele ngomjikelezo ngamunye, ishiya ingxenye emapuletini.
Empeleni, ngenkathi amabhethri e-lead-acid enikeza isitoreji samandla esibalulekile, isikhathi sabo sokuphila siyaphela. Nokho, ukuqonda ikhemikhali eyinkimbinkimbi ngaphakathi kwalawa mabhethri kunikeza ukukhanya ekusebenzeni kwawo kanye nethuba lokwelula isikhathi eside sawo ngokuwanakekela ngokucophelela nokushajwa kabusha. Lunjalo uhambo oluhehayo phakathi kwenhliziyo yamabhethri e-lead-acid - umdanso wamakhemikhali akha izidingo zethu zamandla.
