Txhuas yog xav tau hlauvim nws yog qhov yooj yim dua thiab elastic dua li cov hlau. Aluminium tuaj yeem mus rau qhov chaw thiab tsim cov duab uas cov hlau tsis tuaj yeem, feem ntau sib sib zog nqus los yog sib sib zog nqus ntau dua. Tshwj xeeb tshaj yog rau qhov chaw nrog cov phab ntsa sib sib zog nqus thiab ncaj, aluminium yog cov khoom xaiv.
Qhov txawv ntawm txhuas thiab hlau yog dab tsi?
Zoo. Txawm hais tias muaj kev pheej hmoo rau kev xeb,hlau tseem nyuaj dua li txhuas Thaum txhuas nce zog hauv qhov chaw txias dua, nws feem ntau ua rau cov hniav thiab khawb ntau dua li cov hlau. Cov hlau tsis tshua muaj zog los yog khoov los ntawm qhov hnyav, quab yuam, lossis cua sov.
YPuas yog txhuas yog hlau?
aluminium (Al), kuj sau aluminium, tshuaj lom neeg, lub teeb yuag silvery dawb hlauntawm pawg loj 13 (IIIa, lossis pawg boron) ntawm lub sijhawm. Aluminium yog cov khoom siv hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb cov pob zeb thiab cov hlau tsis yog siv dav tshaj plaws.
Puas yog txhuas muaj zog li hlau?
Aluminium yog kwv yees li ib feem peb ntawm qhov hnyav ntawm cov hlau, lub ntsiab lus tuaj yeem ua kom tuab thiab muaj zog dua thaum tseem txo qhov hnyav hauv tsheb thiab lwm yam kev siv. Raws li cov txheej txheem kev siv alloy thiab cov txheej txheem siv, phaus rau phaus txhuas tuaj yeem forged kom muaj zog yog tias tsis muaj zog dua li qee cov hlau.
Vim li cas txhuas tsis yog hlau?
Aluminium yog ib txwm faib ua hlau. Nws yog lustrous, malleable thiab ductile, thiab muaj hluav taws xob thiab thermal conductivity. Ib yam li cov hlau feem ntau nws muaj cov qauv tsim crystalline ze ze, thiab tsim cov cation hauv cov kua dej.
