Ukutyhilwa kweKhemistri ngasemva kweebhetri zeLead-Acid
Ngaba ukhe wanqumama ukuze ucamngce ngeenkqubo ezintsonkothileyo ezenzekayo phakathi kweebhetri ezineasidi yelothe? Phakathi kwezi bhokisi zingenazintloni kukho umdaniso onyakazelayo wekhemikhali, oququzelela amandla esithembele kuwo. Makhe singene nzulu kwi-nigma ejikeleze ubomi obuyimfihlo ngaphakathi kweebhetri ze-asidi yelothe ngophononongo olufutshane.
Iipleyiti zeNkokheli ziwenza njani uMbane kwi-Sulfur Acid:
Ngaphakathi ngaphakathi kweebhetri ze-lead-asidi zihlala uluhlu lweeseli, nganye igcina iperi yamacwecwe - i-electrode ekhangayo kunye ne-negative, kunye ne-asidi yesulfuric ehlanjululweyo esebenza njengesahluli sazo. Xa igcwaliswe ngokupheleleyo, iseli nganye ihambisa malunga ne-2.1 volts. Kwibhetri ye-6-volt, iiseli ezintathu ziyimfuneko, kunye nebhetri ye-volt-12, iiseli ezintandathu zanele.
Iipleyiti ezikhokelayo ngaphakathi kweseli nganye ziigridi eziyilwe ngokuntsonkothileyo ezinokwakheka kweekhemikhali ezahlukeneyo, eziqatywe ngemathiriyeli esebenzayo eyahlukileyo. Njengoko ibhetri isetyenziswa, iyaphuma, ikhuphe amandla agciniweyo kwaye isebenzise iinxalenye ze-asidi yesulfuric. Kancinci, i-sulfate esuka kwi-asidi igubungela iiplate, inciphisa indawo ekhoyo ukuze i-chemical reaction iqhubeke. Yakuba igqunywe ngokupheleleyo, impendulo iyama, inike ibhetri ingabi namandla.
Ngaphandle kokufikelela kweli nqanaba, kukho ithemba lokuvuka kweebhetri ze-lead-asidi ngokutshaja kwakhona. Emva kokutshaja kwakhona, i-sulfate ibuyela kwi-asidi, ivumela inkqubo ukuba iqalise. Nangona kunjalo, akusiyo yonke i-sulfate ibuyiselwe ngokupheleleyo kunye nomjikelo ngamnye, ishiya inxalenye kwiiplate.
Ngokwenyani, ngelixa iibhetri ze-lead-asidi zibonelela ngogcino lwamandla oluyimfuneko, ubomi bazo buphelile. Nangona kunjalo, ukuqonda ikhemistri entsonkothileyo ngaphakathi kwezi bhetri kunika ukukhanya ekusebenzeni kwazo kunye nokuba nokwenzeka kokwandisa ubomi bazo ngokulondolozwa ngononophelo kunye nokutshaja kwakhona. Olo ke luhambo olunika umdla ngaphakathi entliziyweni yeebhetri ze-lead-asidi-umdaniso weekhemikhali ezibumba iimfuno zethu zamandla.
