Thaum txhua daim kab xev txhuas muaj qee qhov zoo, tsis yog txhua tus ntawm lawv yog tsim los siv sab nraum zoov. Txhawm rau kom cov kab xev ua tau zoo thaum raug cov khoom, koj yuav tsum xav txog ntau yam tseem ceeb:
1. UV Resistance
Ib qho tseem ceeb tshaj plaws thaum siv cov kab xev txhuas sab nraum zoov yog nws lub peev xwm tiv thaiv ultraviolet (UV) hluav taws xob. Kev raug UV ntev ntev tuaj yeem ua rau cov nplaum nplaum, ua rau nws poob nws lub zog sib txuas, discolor, thiab degrade dhau sijhawm.
UV-resistant aluminium daim kab xev yog tsim tshwj xeeb los tiv thaiv UV hluav taws xob yam tsis muaj kev cuam tshuam nws cov txiaj ntsig. Qhov no ua rau nws tsim nyog siv rau hauv daim ntawv thov raug tshav ntuj ncaj qha rau lub sijhawm ntev, xws li lub ru tsev, sab nraum zoov, thiab lwm qhov chaw sab nrauv.
2. Huab cua tsis kam
Ntxiv nrog rau UV tsis kam, aluminium daim kab xev siv sab nraum zoov yuav tsum muaj peev xwm tiv taus cov huab cua sib txawv uas nws yuav ntsib. Qhov no suav nrog nag, daus, kub kub, txias txias, thiab av noo. Daim kab xev nplaum yuav tsum nyob twj ywm thiab ua haujlwm zoo hauv qhov chaw sealing txawm nyob rau hauv huab cua tsis zoo.
Huab cua-resistant aluminium daim kab xev yog tsim los tiv thaiv cov dej noo, kub hloov pauv, thiab kev ntxhov siab ib puag ncig. Qhov no ua rau nws zoo tagnrho rau siv nyob rau hauv sab nraum zoov HVAC systems, insulating kav, sealing ducts, thiab lwm yam. Daim kab xev yuav tsum tsis txhob tev, tawg, lossis poob nws cov txiaj ntsig thaum raug los nag, daus, lossis kub heev.
3. Corrosion Resistance
Corrosion tuaj yeem yog qhov teeb meem loj rau cov ntaub ntawv raug rau cov ntsiab lus, tshwj xeeb tshaj yog nyob rau hauv ntug dej hiav txwv uas dej ntsev tuaj yeem ua kom xeb thiab degradation. Corrosion-resistant aluminium daim kab xev yog tsim los tiv thaiv xeb thiab tuav nws cov nplaum nplaum txawm nyob rau hauv ib puag ncig corrosive.
Cov yam ntxwv no ua rau txhuas daim kab xev yog qhov kev xaiv zoo tshaj plaws rau kev siv sab nraum zoov hauv thaj chaw uas muaj dej noo, ntsev, lossis lwm yam khoom corrosive. Aluminium nws tus kheej yog ib txwm tiv taus xeb, tab sis cov nplaum yuav tsum tau tsim los tiv thaiv cov dej noo thiab ib puag ncig cov kab mob.
4. Kev tiv thaiv kub
Aluminium daim kab xev paub txog nws qhov siab -kub tsis kam, uas ua rau nws haum rau sealing ducts thiab insulating kav uas raug kub heev. Txawm li cas los xij, kev siv sab nraum zoov tuaj yeem nthuav tawm qhov kub thiab txias, txij li hnub kub lub caij ntuj sov mus rau lub caij ntuj no txias hmo.
Siab -kub-resistant aluminium daim kab xev tuaj yeem tiv taus qhov kub thiab txias ntawm -20℃F (-29 degree) thiab 600℃F (315 degree) lossis ntau dua, nyob ntawm cov khoom. Qhov no ua kom cov kab xev yuav ua tau zoo txawm tias nyob rau hauv ib puag ncig kub xws li ru tsev lossis hauv cov chaw raug tshav ntuj ncaj qha.
