txhuas
Aluminium yog lwm yam hlau uas siv ntau zuj zus hauv kev tsim choj, tshwj xeeb tshaj yog rau cov choj me thiab nruab nrab. Aluminium sib dua hlau, tab sis tseem muaj zog txaus rau ntau yam kev siv hauv kev tsim kho.
Cov txiaj ntsig ntawm Aluminium:
- Lub teeb yuag, uas tuaj yeem txo cov nqi thauj mus los thiab kev teeb tsa.
- Tiv taus xeb heev, txawm tias nyob rau hauv qhov chaw muaj xeb heev xws li thaj chaw ntug dej hiav txwv.
- Yooj yim rau kev tsim thiab tsim kho, ua rau muaj kev tsim qauv yooj yim dua.
Qhov tsis zoo ntawm Aluminium:
– Lub zog qis dua piv rau hlau, yog li nws tsis yog ib txwm haum rau cov choj uas ntev heev.
- Tus nqi raw khoom kim heev.
- Nws qhov xwm txheej mos dua xav tau kev tsim tshwj xeeb kom tsis txhob muaj kev hloov pauv mus tas li.
Tooj liab thiab nws cov alloys
Txawm hais tias tsis tshua siv ua cov khoom siv tseem ceeb hauv kev tsim choj, tooj liab thiab nws cov hlau sib xyaw (xws li tooj dag thiab tooj dag) muaj ntau yam kev siv tshwj xeeb. Tooj liab feem ntau siv rau hauv cov khoom dai kom zoo nkauj lossis ua tus coj hluav taws xob vim nws cov hluav taws xob thiab thermal conductivity zoo heev.
Cov txiaj ntsig ntawm tooj liab:
- Zoo heev rau kev xeb thiab oxidation.
- Cov khoom siv thermal thiab hluav taws xob zoo heev, tsim rau cov khoom tshwj xeeb uas xav tau cua sov lossis hloov hluav taws xob.
- Kev zoo nkauj zoo nkauj, feem ntau siv rau hauv cov khoom dai kom zoo nkauj.
Qhov tsis zoo ntawm tooj liab:
- Tus nqi siab heev piv rau hlau lossis hlau.
- Lub zog ntawm cov qauv qis dua, tsis haum rau cov khoom siv tseem ceeb hauv kev tsim choj uas xav tau lub zog siab.
Hlau tsis xeb
Cov hlau tsis xeb yog ib hom hlau uas muaj chromium ntxiv rau kom tsis txhob xeb. Nws yog ib qho kev xaiv nrov heev rau cov qauv uas yuav raug rau cov xwm txheej xeb, xws li cov choj hla dej ntsev lossis cov nyob rau hauv cov chaw ua haujlwm.

Xaus
Kev xaiv cov hlau zoo rau kev tsim choj nyob ntawm ntau yam, suav nrog qhov chaw ntawm tus choj, cov khoom thauj uas nws yuav nqa, cov xwm txheej ib puag ncig, thiab cov peev nyiaj. Hlau thiab hlau tseem yog cov kev xaiv tseem ceeb vim lawv lub zog thiab tus nqi qis. Txawm li cas los xij, lwm cov hlau xws li txhuas thiab stainless hlau kuj ua lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog rau cov ntawv thov tshwj xeeb lossis cov uas xav tau kev tiv thaiv xeb ntau dua.
Thaum cov thev naus laus zis siv tau zoo zuj zus, tej zaum cov hlau tshiab thiab cov hlau sib xyaw ua ke yuav pheej yig dua thiab siv tau zoo dua rau kev tsim choj. Txawm li cas los xij, kev paub txog lub zog, qhov tsis muaj zog, thiab kev siv cov hlau zoo tshaj plaws yuav tseem yog ib feem tseem ceeb ntawm kev npaj thiab tsim choj kom muaj kev nyab xeeb thiab ua tau zoo.
