Pom qhov txawv ntawm tooj liab hlau thiab txhuas xaim hauv lub cev muaj zog ntawm kev soj ntsuam ntawm cov tsheb ciav hlau koom nrog ob peb qhov tseem ceeb pom thiab kev sim:
1.Visual Soj ntsuam:
Xim: Tooj liab hlau muaj xim liab-xim av, thaum txhuas xaim yog nyiaj lossis grey.
Qhov hnyav: Tooj liab hlau yog qhov hnyav dua li txhuas hlau ntawm tib lub cheeb tsam vim mus rau tooj liab lub zog.
2.Txhua:
Txoj kab uas hla: rau tib lub ntsuas cua (tuab), Hlau hlau yuav muaj lub taub hlau loj dua li txhuas muaj qhov qis dua hluav taws xob conduction. Koj tuaj yeem ntsuas qhov taub ntawm cov hlau los pab txheeb xyuas nws.
3.Txoj kev xeem:
Hluav taws xob tsis kam: tooj muaj qhov hluav taws xob qis dua piv rau txhuas. Siv tshuaj multimeter, koj tuaj yeem ntsuas qhov tsis kam ntawm cov hlau. Cov hlau tooj liab yuav qhia cov nqi qis dua qhov tseem ceeb tshaj txhuas hlau ntawm tib lub ntev thiab cov taub.
4.Magnet Xeem:
Cov khoom sib nqus: tooj liab tsis yog kev sib nqus, thaum txhuas yog cov hlau nplaum tsis muaj zog. Koj tuaj yeem siv cov hlau nplaum kom pom tias muaj qhov nyiam. Txhuas hlau yuav qhia ib qho kev nyiam me ntsis, hereas tooj liab yuav tsis.
5.OXIDATION:
Oxidation: Aluminium hlau nyhav rau oxidize ntau nrawm dua tooj liab, tsim cov txheej dawb lossis greyish rau saum npoo. Cov hlau tooj liab yuav tsim kho lub patina lub sijhawm.
6.thermal conductivity: tshav kub dissipation: tooj hlau xov hlau dissipates tshav kub ntau dua li txhuas cov hlau. Yog tias koj khiav lub cev muaj zog thiab xav tias cov xov hlau, tooj yuav ua kom sov qeeb dua piv rau txhuas.
Los ntawm kev sib txuas cov hau kev no, koj tuaj yeem raug txiav txim siab txawm tias lub cev muaj zog hauv koj cov tsheb ciav hlau thauj khoom hlau lossis txhuas cov hlau. Yog tias koj tsis paub meej, kev sab laj ntawm lub cev muaj zog lossis tiv toj cov chaw tsim khoom tseem tuaj yeem muab cov lus teb kom muaj tseeb.
