Lub ntsiab siv ntawm aluminium

Aluminium lub teeb yuag thiab corrosion kuj yog ob qho tseem ceeb ntawm nws cov kev ua tau zoo.
1. Qhov ntom ntawm aluminium yog me me, tsuas yog 2.7g / cm ³, Txawm hais tias nws yog mos, nws tuaj yeem ua rau ntau yam aluminium alloys, xws li tawv aluminium, superhard aluminium, xeb pov thawj aluminium, cam khwb cia txhuas, thiab lwm yam. aluminium alloys yog siv dav hauv kev lag luam tsim khoom xws li dav hlau, tsheb, tsheb ciav hlau, thiab nkoj. Tsis tas li ntawd, qhov chaw foob pob hluav taws, shuttles, thiab cov khoom siv satellites kuj tseem siv ntau ntawm txhuas thiab nws cov alloys. Piv txwv li, lub dav hlau supersonic yog tsim los ntawm kwv yees li 70% txhuas thiab nws cov txhuas alloys. Aluminium kuj tau siv dav hauv kev tsim khoom nkoj, thiab cov nqi ntawm txhuas siv nyob rau hauv cov neeg caij nkoj loj feem ntau mus txog ntau txhiab tons.
2. Aluminium muaj conductivity thib ob tsuas yog nyiaj, tooj liab, thiab kub. Txawm hais tias nws cov conductivity tsuas yog 2/3 ntawm tooj liab, nws qhov ceev tsuas yog 1/3 ntawm tooj liab. Yog li ntawd, thaum thauj tib tus nqi hluav taws xob, qhov loj ntawm txhuas hlau tsuas yog ib nrab ntawm tooj liab hlau. Cov oxide zaj duab xis nyob rau saum npoo ntawm txhuas tsis tsuas yog muaj peev xwm tiv taus corrosion, tab sis kuj muaj qee qhov kev rwb thaiv tsev, yog li txhuas muaj ntau yam kev siv hauv kev lag luam hluav taws xob, kev lag luam hlau thiab cable, thiab kev lag luam wireless.
3. Aluminium yog ib tug zoo conductor ntawm tshav kub, nrog ib tug thermal conductivity peb zaug ntau dua hlau. Hauv kev lag luam, txhuas tuaj yeem siv los tsim ntau yam khoom siv hluav taws xob, khoom siv hluav taws xob, thiab cookware.
4. Aluminium muaj qhov zoo ductility (thib ob tsuas yog kub thiab nyiaj), thiab tuaj yeem ua rau aluminium foil thinner dua 0.01mm ntawm qhov kub ntawm 100 degree mus rau 150 degree . Cov aluminium foils no tau dav siv rau ntim cov luam yeeb, khoom qab zib, thiab lwm yam. Lawv tuaj yeem ua rau txhuas hlau thiab strips, thiab tuaj yeem dov rau hauv ntau yam khoom txhuas.
5. Qhov saum npoo ntawm txhuas, vim nws cov oxide tiv thaiv zaj duab xis, tsis yooj yim corroded thiab feem ntau yog siv los tsim cov tshuaj reactors, cov khoom siv kho mob, cov khoom siv tub yees, cov khoom siv roj av refining, roj av thiab cov kav dej ntuj, thiab lwm yam.
6. Cov hmoov txhuas muaj cov xim dawb dawb (feem ntau cov xim ntawm cov hlau hauv cov hmoov hlau feem ntau yog xim dub), thiab feem ntau yog siv los ua cov txheej, feem ntau hu ua cov hmoov nyiaj lossis xim nyiaj xim, los tiv thaiv cov khoom hlau los ntawm corrosion thiab zoo nkauj.
