Aluminium muab ib tug zoo conductivity rau weightratio tshaj tooj liab, thiab yog li ntawd kuj yog siv rau kab hluav taws xob cov kab hluav taws xob, suav nrog cov khoom siv hluav taws xob siv hluav taws xob thiab cov kab hluav taws xob hauv cheeb tsam, nrog rau kev siv hluav taws xob kab hluav taws xob ntawm qee lub dav hlau. Nws muaj nqi thiab qhov hnyav zoo dua tooj liab cov xov hlau.

Kuj paub, vim li cas Aluminium siv rau hauv cables?

Aluminium tshaj lwm cov hlau ua ib qho nyiaj siv ua haujlwm kab . Nws yog siv nyob rau hauv ntau sectors xws li aircraft, railways, hwj chim kab thiab ntau ntxiv. Aluminium nyiaj siv ua haujlwm kab kuj txo corona, tso tawm ntawm hluav taws xob thaum muaj peev xwm loj hauv cov hlau.

Ib sab saum toj no, vim li cas Aluminium tsis siv rau kev xaim hluav taws xob? Nws yog tsis yog teeb meem loj thaum tooj liab kab hluav taws xob xeb, txij li cov tooj liab oxide uas cov ntaub ntawv yog electrolyconductive. Thaum twg aluminium kab hlau rhuav xeb, dawb oxide yog tsis yog ib qho zoo heev hluav taws xob tus thawj coj. Nws tsis cuam tshuam nrog kev ntws ntawm hluav taws xob , thiab dua, tuaj yeem ua rau overheating.

Hauv qhov no, vim li cas Aluminium siv sab nraum zoov?

Thaum siv tsis kho aluminium sab nraum zoov , ib txheej txheej thinoxide yog tsim rau ntawm qhov chaw. Thaum twg txhuas los nyob rau hauv kev sib cuag nrog oxygen, ib tug oxide txheej cov ntaub ntawv, uas yog heev txuas mus rau lub txhuas nto. Cov txheej tiv thaiv themetal tiv thaiv kev tawm tsam ntxiv, yog li ua rau nws tiv thaiv corrosion.

Vim li cas Aluminium siv rau hauv fais fab cables tsis siv tooj liab?

Tooj liab thiab txhuas feem ntau yog siv raws li hluav taws xob conductors hauv hluav taws xob cables vim lawv tsis tshua muaj kuj thiab zoo heev conductivity. Vim li no txhuas pom kev txaus siab nyob rau hauv loj loj kab thiab kab rau saum taub hau hwj chim kev faib tawm.
