Qalabka Galvanic waa Qalabka Kiimikada oo si Fiican u fahmaya
Kaadida Galvanic waxay dhici kartaa oo kaliya marka laba metal oo kale oo ka mid ah birta elektaroonikadu ay kudhow yihiin mid kale oo sidoo kale ku qulqulaan dareeraha elektarooriga ah (sida biyaha cusbada).
Marka tani dhacdo, dhuxusha iyo elektaroolka ayaa abuuraya unug galvanik ah. Unuggu wuxuu saameyn ku yeelan karaa biraha dhuxusha kharashka kale.
Xaaladda digniinta, birta waxaa lagu qallajiyay kharashka naxaasta. Laba sano oo kaliya ka dib markii la xidhxidhay baalal naxaas ah, ciddiyaha birta ah ee loo isticmaalay in lagu haysto naxaaska markabka saaran markabka ayaa horeyba u burburay, taasoo keentay in warqadaha naxaasta ay ku dhacaan.
Sida Qalitaanka Galvanic u Shaqeeyo
Dhuxulada biraha iyo birta dhamaantood waxay leeyihiin lahjadaha kale ee electrode. Awoodaha korontada ku shaqeeyaa waa qiyaas heer qaran ah oo ah muraayad jimicsi ah si ay u noqoto mid firfircoon oo loo isticmaalo qalabka elektarooniga ah. Dhaqdhaqaaqa firfircoon, ama mid ka yaryar, biraha ayaa badanaa ah inuu noqdo qaab anode (fiilo si fiican loo soocay) oo loo yaqaan 'electrolytic environment'. Qofka yar ee firfircoon, ama qof aan dahab ahayn waa bir, waxay u badan tahay inuu yahay qaabka cathode (aan si xun loo daboolin electrode) marka isku dabiiciga ah.
Cudurka elektarooligga wuxuu u shaqeeyaa sida xargaha guuritaanka ion, u dhaqashada ion biraha ka soo boodboodka ilaa cathode. Birta anode, natiijada, waxay u dhaqso badan tahay si ka duwan sida kale, halka maadada cathode ay hoos u dhigto si tartiib tartiib ah, mararka qaarkoodna, ma aha wax khaldi ah.
Xaaladda Qaylo-dhaanta , birta quruxda badan (copper) waxay u dhaqantay sida cathode, halka birta sharaf ka hoosaysa ay u dhaqantay sida anode.
Qulqulka dhuunta ayaa laga lumay kharashka naxaasta, taasoo ugu dambeyntii keentay in si deg deg ah ciddiyaha u sii xumaato.
Sida Loo Ilaaliyo Dhibaatada Galvanic
Iyada oo fahamkayaga hadda jira ee korontada galvanikka, maraakiibta birta ah ayaa hadda lagu rakibay 'anod-fedex', oo aan si toos ah u ciyaarin hawlgalka markabka, laakiin waxay u adeegaan inay ilaaliyaan qaybaha dhismaha ee markabka. Anodyada xayawaanka ah waxaa badanaa laga sameeyaa zinc iyo magnesium , macdano leh awood aad u yar. Maadaama ay anodiyaal farabadan ay xumeeyeen oo ka sii darayaan waa in la beddelo.
Si loo fahmo waxa ay birtu noqonayso anode oo u dhaqmi doonta sidii cathode ah ee deegaannada electrolytic, waa in aan fahanno awooda jilicsanaanta ama awooda electrode. Tan waxaa guud ahaan lagu qiyaasaa iyadoo la tixraacayo Istaandarada Isticmaalka Kaluumeysiga (SCE).
Liistada biraha ah, oo loo qorsheeyey sida ay u kala duwan yihiin (badi) ee badda dhexdeeda ah ayaa laga arki karaa jadwalka hoose.
Waa in sidoo kale la tilmaamaa in korontada galvanikadu aysan ku dhicin oo keliya biyaha. Unugyada Galvanik waxay ka sameysan karaan wax elektaroolik ah, oo ay ku jiraan hawada qoyan ama carrada, iyo kiimikada kiimikada.
