Cov khoom siv hluav taws xob tau yooj yim heev vim lawv cov hluav taws xob dawb. Insulators tawm tsam hluav taws xob tam sim no thiab ua rau cov neeg ua haujlwm tsis zoo. Qee cov khoom siv feem ntau yog tooj liab, txhuas, kub, thiab nyiaj. Qee cov insulators feem ntau yog iav, cua, yas, roj hmab, thiab ntoo.
YPuas yog aluminium insulator?
Aluminium muaj qhov emissivity ntawm ib ncig ntawm 0.04. Qhov ntawd txhais tau hais tias nws radiates tsawg heev ntawm nws qhov chaw, uas yog ib qho laj thawj vim li cas cov radiators tsis yog tsim los ntawm txhuas! Aluminium foil tuaj yeem yog cov khoom siv hluav taws xob zoo vim nws tsis muaj cua sov tawm mus rau ib puag ncig.
YPuas yog Aluminium tus neeg xyuas pib?
Aluminium muaj ntau yam: nws tsis yog tsuas yog cov khoom siv thoob ntiaj teb, tab sis kuj ib lub tshuab hluav taws xob zoo meej. Niaj hnub no, nrog rau tooj liab, txhuas ua kom lub zog xa mus thoob ntiaj teb.
Vim li cas txhuas yog qhov zoo insulator?
Vim aluminium foil qhia txog lub teeb, nws tuaj yeem siv rau rwb thaiv tsev, tshwj xeeb tshaj yog nyob rau thaj chaw uas yuav tsum tau tiv thaiv tshav kub. Thaum nws siv nrog lwm cov ntaub ntawv, nws tuaj yeem siv los ua kom sov ib cheeb tsam, ib yam nkaus. … Aluminium ntawv ci tuaj yeem khaws cov khoom zoo li cov xov hlau lossis cov kav dej, vim nws ntxiab cua thaum nws qhwv ib ncig ntawm ib qho khoom.
Puas yog txhuas lub tshav kub zoo?
Aluminium foil yog cov khoom siv hluav taws xob zoo heev, uas txhais tau hais tias nws yog cov insulator tsis zoo thaum nws nyob rau hauv kev sib cuag nrog tej yam kub. Nws kuj yog nyias nyias uas cov cua sov tuaj yeem dhau los ntawm nws yooj yim heev thaum nws muaj kev sib cuag ncaj qha. Qhov no yog lawv hom kev hloov hluav taws xob uas aluminium tsis zoo thaum nres.
