Ngabe i-aluminium iphatha ugesi?
I-Aluminium iyinsimbi egcwele emvelweni. Kuyinto ebonakalayo enhle yokusetshenziswa kwezimboni kanye nohlobo lwezinto zensimbi ezinobuhle obuhle kagesi nobudlova. Ngesikhathi esifanayo, I-aluminium nayo iyinsimbi engaqhuba ugesi. I-Aluminium ingaqhuba ugesi ngoba kunenani elikhulu lama-elektroni amahhala ngaphakathi kulo. Lawa ma-elektroni amahhala enza ukunyakaza okungekho emthethweni okungekho emthethweni ku-metal crystal. Lapho zithinteka insimu kagesi yangaphandle, Bazohamba ngendlela eqondile baqonde ngaphesheya kwensimu kagesi, Ngaleyo ndlela ukwakha i-Electric yamanje.
I-aluminium iphatha kanjani ugesi?
Uyini umgomo wokuhunyushwa kwe-aluminium foil?
Umgomo we-Aluminium Collection usekelwe ikakhulukazi esakhiweni se-elekthronikhi sama-athomu awo kanye nezimpawu zamabhondi wensimbi. Kunezizathu ezinhlanu zokuthi kungani i-aluminium ingaqhuba ugesi.
1. Ukuba khona kwama-elektroni amahhala
Ama-athomu we-aluminium anama-elektroni amathathu we-valence engxenyeni yawo yangaphandle. Emakristalu ensimbi, Lezi zimonyo ze-valence azixazululelwa ku-athomu elithile, kepha ingahamba ngokukhululeka kulo lonke i-metal crystal ukwakha lokho okubizwa ngokuthi “Ulwandle lwe-elektroni”. Lawa ma-elektroni ahamba ngokukhululekile ayisiza esiyisisekelo sokuvuselelwa kwezinsimbi.
2. Izibopho zensimbi:
Ama-athomu we-aluminium aboshwe ndawonye ngamabhondi wensimbi. Amabhondi weMetallic aluhlobo olukhethekile lwebhondi yamakhemikhali lapho ama-ion asungulwe ngama-athomu wensimbi ahlelwe ngolwandle lwama-elektroni amahhala. Ama-elektroni wamahhala ahamba ngokukhululeka kulo lonke isakhiwo sekristalu, ukwenza insimbi ibe ngumqhubi omuhle kagesi.
3. Ukugeleza kwe-elektroni namanje
Lapho i-voltage isetshenziswa emaphethelweni womabili omqhubi we-aluminium, Ama-elektroni amahhala azohamba ngendlela eqondile ngaphansi kwesenzo sensimu kagesi. Le nhlangano ye-elektroni eqondakalayo yakha i-Electric yamanje. Ngakho-ke, I-Aluminium iyakwazi ukwenza ugesi.
4. Isakhiwo se-Lattice:
Isakhiwo se-Crystal se-aluminium yi-cubic egxile ebusweni (I-FCC) ukwakheka, okuvumela ama-elektroni ukuthi ageleze ngokukhululeka ethangeni, Ngaleyo ndlela kuthuthukisa ukusebenza.
5. Ukumelanakabisa:
Ukumelana ne-aluminium kuphansi, cishe ngo-2.65 × 10 ^ -8 ω · m, okuphakeme kancane kune-zethusi (cishe ngo-1.68 × 10 × 10 ω · m), Kepha kuseyinto ephathekayo enhle yokuziphatha. Lokhu kumelana okuphansi kusho ukuthi ama-elektroni angadlula kubaqhubi be-aluminium kalula.
