Aluminium Alloy Vs Polyvinyl Chloride Vs Reflective Film: Yam khoom twg yog qhov ruaj khov siab tshaj - Cov Ntawv Ceeb Toom Txog Kev Nyab Xeeb? Phau Ntawv Qhia Kom Paub

Tib lub cim "High-Txoj Kev Txaus Siab", $ 30 rau aluminium alloy, $ 8 rau PVC, $ 20 rau zaj duab xis reflective. Tus nqi sib txawv plaub npaug! Yuav ua li cas txawv yog durability?
Niaj hnub no, cia peb txiav mus rau qhov kev sib tw thiab sib piv ncaj qha rau cov kav ntev, huab cua thiab kev ceeb toom ua haujlwm ntawm peb cov ntaub ntawv no. Nyeem qhov no thiab koj yuav paub qhov twg los nqis peev.
Round 1: Aluminium Alloy - Huab tais ntawm Durability tab sis tus nqi pib
Lub zog tseem ceeb ntawm aluminium alloy siab - cov cim ceeb toom kev phom sij tuaj yeem suav nrog plaub lo lus: 50 xyoo tsis tawg.
Aluminium muaj qhov ntom ntawm tsuas yog 2.7 g / cm3, txog ib feem peb ntawm cov hlau, tab sis tom qab alloying nws tuaj yeem ncav cuag 110 txog 650 MPa, lossis ntau tshaj qhov tshwj xeeb nruj ntawm cov hlau. Qhov tseem ceeb tshaj, aluminium nto ib txwm ua ib qho nyuaj, ntom oxide zaj duab xis, tiv taus corrosion thiab kev laus, thiab ua tau zoo hauv kev lag luam thiab ntug dej hiav txwv ib puag ncig. Tom qab anodization, zaj duab xis thickness tuaj yeem dhau 10 micrometers, lub thickness ntawm cov fluorine txheej yuav ua tau ntau tshaj 30 micrometers, thiab huab cua muaj peev xwm yuav ntau tshaj 20 xyoo.
Hauv kev siv tswv yim, cov cim qhia txog aluminium alloy tuaj yeem siv rau 50 txog 100 xyoo. Lawv tsis yog-sib nqus, tsis cuam tshuam nrog cov cuab yeej precision thiab tuaj yeem hloov tau ntawm nws tus kheej, ua rau kev saib xyuas qis heev.
Txawm li cas los xij, lawv muaj ob qhov teeb meem loj.
Ua ntej, cov txheej txheem vuam yog qhov nyuaj, txwv tsis pub cov duab tsis zoo thiab cov khoom lag luam. Qhov thib ob, qhov kev ua tiav ntawm qhov tsawg kawg nkaus ua rau pom kev tsis pom zoo nyob rau hauv qis - teeb pom kev zoo - luv luv, tsis muaj zaj duab xis cuam tshuam thaum hmo ntuj, qhov tseem ceeb yog "qhov muag tsis pom kev."
Aluminium alloy yog ib qho kev sib tw - mus ntev, tab sis koj yuav tsum lees tias nws yog qhov pib kim thiab nyuaj rau hloov.
Round 2: PVC- qhov kev xaiv muaj txiaj ntsig zoo, tab sis tsis txhob cia siab tias nws yuav yog tsev neeg qub txeeg qub teg.
PVC high voltage ceeb toom cov paib yog cov khoom xa tuaj tshaj plaws ntawm kev lag luam tam sim no rau qhov yooj yim: lawv pheej yig, siv tau yooj yim thiab nplua nuj.
PVC polymer chains muaj ntxiv los tiv thaiv- UV additives thiab plasticizers kom nws hloov tau, npuas -dawb, curl-dawb thiab xeb- dawb ntawm qhov kub ntawm -20℃C℃mus rau 60℃. PVC PVC ib qho ntawm feem ntau pom zoo substrates, raws li GB 2894 "Safety Signs and its Guide to Use. Professional manufacturers' PVC high-siab ceeb toom cov paib siv siab-txoj kev tshuaj ntsuam luam ntawv thev naus laus zis, xim saturation siab. Ua ke nrog cov txheej txheej xaiv xaiv, lawv xyuas kom meej tias cov lus ceeb toom sai sai thiab pom tseeb hauv cov huab cua tsis tshua muaj teeb pom kev zoo.
Txawm li cas los xij, PVC muaj cov kev txwv tseem ceeb.
PVC li qub tsis haum rau ntev - siv sab nraum zoov vim huab cua tsis zoo. Engineered reflective membranes feem ntau muaj lifespan ntawm 3 mus rau 7 xyoo rau PVC substrates; txawm tias siab heev - siv cov pa roj carbon monoxide tuaj yeem khaws tau tsuas yog 50% ntawm lawv qhov ci ci pib tom qab 7 xyoo. Tsis tas li ntawd, PVC qib qis, hnav yooj yim, ntev - lub sij hawm raug rau sab nraum zoov yuav ploj mus thiab nkig.
PVC zoo li tus sprinter: nws ua tau zoo rau thawj peb xyoos, ces pib poob.
Round Peb: Reflective Sheeting - Qhov tiag "Hmo ntuj Killer," Tab sis nws tsis yog tus neeg ua si Standalone
Ntau tus neeg xav tias cov khoom siv hluav taws xob yog cov khoom sib cais, uas tsis muaj tseeb. Reflective sheeting yog txheej txheej txheej uas yuav tsum tau txuas nrog aluminium alloy lossis PVC puag phaj ua haujlwm.
Lub hauv paus ntsiab lus tseem ceeb ntawm lub phaj reflector yog thim rov qab - siv iav microspheres, lossis microprism thev naus laus zis los cuam tshuam lub teeb los ntawm lub teeb ci rov qab los ntawm txoj kev nws tuaj. Raws li qib:
Qib Engineering, muaj txiaj ntsig lub neej 3-7 xyoo, haum rau cov paib txoj kev ib ntus. Kev ntsuas siab siab (Class 3), 10 xyoo kev pabcuam lub neej, 3 zaug ci dua li qib engineering, haum rau kev loj. Ultra-siab siv qib (theem 4), microprism qauv, 10 xyoo kev pab cuam lub neej, tsis tsawg kawg yog 50% ntawm thawj brightness tom qab 10 xyoo, haum rau mus tas li signage. Wide Angle Class (Qib 5), 10 xyoo kev pab cuam lub neej, microprism qauv, haum rau industrial chaw.
Qib 4 thiab 5 reflectors khaws ntau tshaj li ib nrab ntawm lawv qhov pib ci ntsa iab tom qab 10 xyoo ntawm kev siv ib txwm, raws li Ministry of Transport standard JT / T279. Fluorescent daj ceeb toom cov cim muaj ntau tshaj li 60% pom dua li qub, muab cov cim ceeb toom ntawm 2-3 vib nas this.
Txawm li cas los xij, tus yuam sij rau kev ua yeeb yaj kiab zoo yog lawv cov substrate. Yog hais tias siv rau PVC, cov substrates deteriorate ua ntej, rendering txawm qhov zoo tshaj plaws films tsis siv. Tsuas yog thaum thov ntawm aluminium alloy tuaj yeem ua rau cov substrates tiag tiag ncav cuag lub neej ntev tshaj 10 xyoo.
Reflective zaj duab xis zoo li "hnub pom kev tsom iav," tab sis lawv xav tau ib qho "thav duab".
Kev txiav txim: Yuav xaiv li cas? Xav txog koj cov kev xaiv
Screen luam ntawv nrog PVC yog txaus rau sab hauv tsev faib chav. Tus nqi qis, tsis muaj dej tsis zoo thiab noo noo- tiv taus, nws yog qhov zoo txaus kom kav ntev dua tsib xyoos yam tsis tas siv nyiaj ntawm aluminium alloy.
Rau sab nraum zoov substations, aluminium alloy substrate nrog plaub-theem reflective films yuav tsum tau xaiv. 20 xyoo ntawm corrosion kuj ntxiv rau 10 xyoo ntawm reflectivity- ib tug tiag tiag - sij hawm peev, 10 xyoo kev txhawj xeeb- siv dawb. Qhov no yog qhov sib xyaw thiab cov qauv ntawm feem ntau cov tuam txhab fais fab.
PVC reflectors yuav tsum tau xaiv rau kev tsim kho ib ntus ntawm laj kab. Lub teeb yuag, pheej yig, hloov tau yooj yim, qhov project yuav raug tshem tawm ncaj qha tom qab ua tiav, yuav tsis ua rau poob nyiaj txiag.
Hauv thaj chaw txias dua, xaiv aluminium alloy lossis txias - PVC tiv taus. Ordinary PVC tuaj yeem ua nkig ntawm rho tawm 30 degrees Celsius, thaum aluminium alloy tsis cuam tshuam tag nrho.
Hauv luv luv: Aluminium alloy rau pem teb, reflective zaj duab xis rau qab nthab, PVC rau pob nyiaj siv. Xav txuag nyiaj? Xaiv PVC. Xav tau kev thaj yeeb ntawm lub siab? Xaiv aluminium alloy nrog reflective zaj duab xis. Xav hla nws? Tom qab ntawd xaiv aluminium alloy nrog plaub -degree reflective zaj duab xis- nws tseem yuav ci hauv cov nyiaj laus.
Tsis txhob ntxhov siab txog kev xaiv! Nrhiav qhov zoo, tsis tas yuav kim tshaj plaws.
