Puas yuav Aluminium Ntawv Nyiaj Daim Kab Xev Deteriorate Hauv Lub Hnub?

Aluminium ntawv ci daim kab xev feem ntau yog tsim los ntawm txhuas ntawv ci thiab siab -sensitive nplaum. Raws li cov txheej txheem tseem ceeb, aluminium foil nthuav tawm lub cev zoo heev. Aluminium inherently muaj ib co℃ntawm oxidation kuj. Thaum raug tshav ntuj, ib zaj duab xis tiv thaiv ntom ntom ntawm aluminium oxide cov ntaub ntawv ntawm nws qhov chaw. Cov yeeb yaj kiab no zoo tiv thaiv oxidation ntxiv, tswj cov txheej txheem kev ncaj ncees ntawm cov ntawv ci. Txawm tias tom qab ntev raug rau ultraviolet hluav taws xob, lub zog thiab ruaj khov ntawm aluminium ntawv ci tseem tsis cuam tshuam, thiab nws yuav tsis corrode lossis xeb sai li qee cov hlau.

Hais txog lub siab-sensitive nplaum, nws yog ib qho tseem ceeb ntawm kev ua tiav cov nplaum ua haujlwm ntawm aluminium foil daim kab xev. Feem ntau hais lus, siab -zoo siab- cov nplaum nplaum yog tsim los nrog huab cua tsis kam, uas yog, lawv hloov tau rau ntau yam huab cua, hauv siab thaum lawv txhim kho thiab tsim khoom. Nyob rau hauv tshav ntuj, hluav taws xob ultraviolet thiab qhov kub thiab txias yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau lub siab- cov nplaum nplaum. Cov hluav taws xob ultraviolet tuaj yeem degrade cov ntaub ntawv polymer hauv lub siab- nplaum nplaum, ua rau txo qhov adhesion; Qhov kub thiab txias tuaj yeem ua rau cov nplaum nplaum los yog ua kom nws cov txheej txheem kev laus. Txawm li cas los xij, rau kev tsim nyog aluminium ntawv ci daim kab xev tsim tshwj xeeb rau kev siv sab nraum zoov, lub siab- cov nplaum nplaum tshwj xeeb yog tsim tshwj xeeb thiab ua tiav los muab cov UV zoo heev thiab siab - qhov kub thiab txias. Nyob rau hauv ib txwm tshav ntuj thiab kub tej yam kev mob, nws tuav ruaj khov adhesion rau ncua sij hawm, tiv thaiv sai poob ntawm adhesion tom qab luv luv los yog nruab nrab raug.

Txawm li cas los xij, qhov no tsis tau txhais hais tias aluminium ntawv ci daim kab xev yuav tsis raug puas los ntawm lub hnub. Kev raug tshav ntuj ntev ntev, xws li nyob rau hauv cov suab puam nrog lub hnub ci hluav taws xob siv hluav taws xob ntau thiab qhov kub thiab txias ntawm nruab hnub thiab hmo ntuj, tuaj yeem maj mam degrade qhov kev ua tau zoo ntawm aluminium foil daim kab xev. Ntev ntev raug rau UV hluav taws xob thiab kub kub tuaj yeem ua rau lub siab tsis muaj zog - cov nplaum nplaum, thaum kawg ua rau daim kab xev nplaum. Txawm hais tias cov ntawv txhuas txhuas yog qhov ruaj khov, nws tuaj yeem tsim cov kab nrib pleb zoo lossis deformation vim ntev - lub sij hawm thermal expansion thiab contraction cycles, cuam tshuam nws tag nrho kev ua tau zoo.
