Ib qho tseem ceeb tshaj plaws uas yuav tsum tau xav txog thaum siv aluminium ntawv ci daim kab xev yog nws kam rau ua kom sov. Hauv tsab xov xwm no, peb yuav ua tib zoo saib seb qhov kub ntawm aluminium foil daim kab xev tuaj yeem tiv taus.
** Cov Txheej Txheem ntawm Aluminium Ntawv Nyiaj Daim Kab Xev
Yuav kom nkag siab txog cov khoom thermal ntawm aluminium ntawv ci daim kab xev, nws yog ib qho tseem ceeb kom paub tias nws yog dab tsi. Aluminium foil daim kab xev muaj peb yam tseem ceeb:
1) Aluminium ntawv ci txheej - qhov no yog txheej txheej sab nraud ntawm daim kab xev thiab yog ib feem uas muab nws cov khoom tshwj xeeb xws li kev xav, yoog raws, thiab ua haujlwm ntev.
2) Cov nplaum nplaum - qhov no yog txheej txheem ncaj qha rau ntawm qhov chaw uas daim kab xev yuav siv. Nws yog lub luag haujlwm rau kev sib txuas daim kab xev rau saum npoo thiab khaws cia rau hauv qhov chaw.
3) Cov txheej txheem rov qab - qhov no yog txheej txheej uas muab kev txhawb nqa ntxiv rau cov nplaum txheej. Nws feem ntau yog ua los ntawm cov ntaub ntawv xws li ntawv lossis yas thiab pab ua kom cov nplaum tsis txhob lo rau nws tus kheej.
** Thermal Properties of Aluminium Foil Daim kab xev
Aluminium foil paub txog nws cov thermal conductivity zoo heev thiab nws muaj peev xwm los cuam tshuam cov cua sov. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cov ntawv thov uas qhov kev tswj hwm kub yog qhov tseem ceeb. Aluminium foil daim kab xev yog tsis muaj kev zam rau qhov no. Cov nplaum txheej ntawm aluminium ntawv ci daim kab xev yog tsim los tiv taus qhov kub thiab txias, ua rau nws haum rau siv nyob rau hauv ob qho tib si kub thiab txias. Feem ntau, aluminium ntawv ci daim kab xev tuaj yeem tiv taus qhov kub ntawm -65 degree F txog 300 degree F.
** Cov yam ntxwv uas cuam tshuam rau cov khoom cua sov ntawm Aluminium Ntawv Nyiaj Daim kab xev
Thaum aluminium ntawv ci daim kab xev muaj cov khoom siv thermal zoo, muaj ntau yam uas tuaj yeem cuam tshuam nws cov kev ua haujlwm ntawm qhov kub thiab txias. Qee qhov xwm txheej no suav nrog:
1) Lub thickness ntawm aluminium ntawv ci txheej - Thicker aluminium foil txheej yog zoo dua ntawm kev kub siab. Cov khaubncaws sab nraud povtseg yuav tsis tuaj yeem tiv taus qhov kub thiab txias li cov khaubncaws sab nraud povtseg.
2) Hom nplaum siv - Cov nplaum sib txawv muaj ntau theem ntawm kev ua siab ntev rau qhov kub thiab txias. Qee cov nplaum nplaum zoo dua thaum tiv taus qhov kub thiab txias dua li lwm tus.
3) Qhov saum npoo ntawm daim kab xev yog siv rau - Qee qhov chaw yuav hloov cua sov sai dua li lwm tus, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm daim kab xev.
4) Lub sij hawm raug rau qhov kub thiab txias - Qhov ntev ntawm daim kab xev raug rau qhov kub thiab txias, qhov ntau nws yuav degrade raws sij hawm.
** Daim ntawv thov ntawm Aluminium Ntawv Nyiaj Daim Kab Xev Thaum Kub Kub
Aluminium foil daim kab xev tuaj yeem siv rau ntau yam kev siv uas muaj qhov kub thiab txias. Qee qhov kev thov no suav nrog:
1) HVAC systems - Aluminium ntawv ci daim kab xev yog feem ntau siv nyob rau hauv HVAC systems los kaw cov cua ducts thiab insulate cua sov thiab cua txias systems.
2) Hluav taws xob rwb thaiv tsev - Aluminium ntawv ci daim kab xev feem ntau yog siv los ua cov khoom siv hluav taws xob kub kub vim nws cov thermal conductivity zoo heev thiab muaj kev cuam tshuam.
3) Automotive kev lag luam - Aluminium ntawv ci daim kab xev yog siv nyob rau hauv kev lag luam automotive rau insulate thiab tiv thaiv hluav taws xob thaiv thiab cov khoom los ntawm cov cua kub generated los ntawm engine.
4) Aerospace kev lag luam - Aluminium ntawv ci daim kab xev yog siv nyob rau hauv lub aerospace kev lag luam los insulate thiab tiv thaiv rhiab hluav taws xob Cheebtsam los ntawm cov huab cua kub generated thaum lub sij hawm spacecraft rov nkag.
** Lus xaus
Nyob rau hauv cov ntsiab lus, aluminium ntawv ci daim kab xev yog ib tug ntau yam nplaum daim kab xev uas muaj peev xwm tiv taus kub ntawm -65 degree F mus rau 300 degree F. Nws zoo heev thermal zog ua rau nws zoo tagnrho rau siv nyob rau hauv ntau yam kev siv nyob rau hauv lub tshav kub tswj yog ib qho tseem ceeb. Cov yam ntxwv uas cuam tshuam rau kev ua haujlwm ntawm aluminium ntawv ci daim kab xev ntawm qhov kub thiab txias muaj xws li lub thickness ntawm aluminium ntawv ci txheej, hom nplaum siv, qhov saum npoo ntawm daim kab xev yog siv rau, thiab lub sij hawm raug rau qhov kub thiab txias. Nrog rau kev siv thiab tuav kom zoo, aluminium ntawv ci daim kab xev tuaj yeem muab kev txhim khu kev qha hauv cov ntawv thov kub rau xyoo tom ntej.
