1.Qhov yog qhov corrosion tsis kam ntawm cov xim-coated galvanized steel kauj refected?
Galvalume (55% Aluminium-43.4% Zinc-13.4% Zinc-1.6% Silicon Alloy): Qhov no yog thawj kab ntawm kev tiv thaiv rau huab cua tsis kam. Lub luag haujlwm ntawm txhuas: muab kev tiv thaiv zoo heev, sib xyaw ua ke oxide txheej txheem (dej vaposive Aluminium nws tus kheej yog ruaj khov nyob rau hauv cov huab cua. Lub luag haujlwm ntawm Zinc: muab kev tiv thaiv kev tua tsiaj anode fij. Thaum txheej txheej khawb lossis cov npoo yog nthuav tawm, zinc corrode nyiam, tiv thaiv cov hlau substrate hauv qab no.
Lub luag haujlwm ntawm silicon: txhim kho txoj kev sib raug zoo ntawm cov txheej thiab cov hlau substrate, inhibit txoj kev loj hlob ntawm braintallic tebchaw, thiab ua kom cov txheej sib xyaw ua ke thiab ua kom nruj dua.
Piv nrog rau cov ntawv loj hauv galvanized, tshwj xeeb yog feem ntau 2-6 zaug ntau qhov chaw muaj kev tiv thaiv kev lag luam Qhov no txhais tau hais tias lub substrate yog tsawg dua li xeb, muab ib lub hauv paus ntau dua rau cov xim xim saum toj no.
2. Qhov twg tsis muaj kev tiv thaiv cov txiaj ntsig ntawm cov organic txheej ntawm cov xim-coated galvanized steel coils manifest?
Xim txheej (polyester, hloov kho polyester, High-durability polyester, thiab lwm yam) yog tus yuam sij los tiv thaiv ib puag ncig kev yaig thiab tswj cov ntsej muag.
UV Yaus: Cov xim zoo xim-txheej tshwj xeeb, tshwj xeeb yog UV nqus dej thiab cov roj av khov kho, uas tuaj yeem ncua kev laus ntawm cov txheej txheem vim UV kis tau.
Tshuaj lom neeg tiv thaiv: txheej tuaj yeem tiv thaiv cov yaig ntawm cov tshuaj lom neeg ib puag ncig, kev tiv thaiv cov kuab paug los nag, yaj, los yog poob nws cov gloss.
Ya ya ua kom tiv thaiv: ib qho zoo sib zog tuaj yeem thaiv cov dej ntws vapones, tiv thaiv dej ntawm cov hlau los yog ua rau txheej txheem npuas los yog poob.
Cov txheej txheem kub tsis kam: cov txheej muaj qhov hloov tau zoo thiab cov nplaum, thiab tuaj yeem tiv thaiv qhov kub loj uas tsis muaj kev tawg lossis tev.
3.Yog dab tsi yog qhov kev ua kom pom tseeb ntawm huab cua tiv thaiv?
Ntev ntev cov xim ruaj khov: Cov xim tuaj yeem tswj tau ntau xyoo nyob rau hauv ib puag ncig sab nraud tsis pom tseeb (tshwj xeeb yog cov txheej txheem PVDF).
Gloss khaws cia: ci ntsa iab tsawg zuj zus, thiab cov tsos yog ntev-ntev thiab tshiab.
Txheej Txheej Zog: nws tsis yooj yim rau tawg, hmoov, hliscister, tev, thiab lwm yam.
Kev tiv thaiv substrate: Ua tau zoo tiv thaiv cov txheej txheem ntawm xeb thiab ua kom cov qauv muaj zog thiab lub neej ntawm cov khoom siv.
4.Qhov qhov tseem ceeb twg cuam tshuam rau huab cua tiv thaiv?
Hom txheej txheej: Qhov no yog qhov txiav txim siab ntawm qhov. PVDF> HDP> SMP> Dog dig Polyester. PVDF Txheej muaj cov huab cua kev tiv thaiv zoo tshaj plaws thiab feem ntau yog siv rau cov tsev kawm sab nrauv thiab cov chaw hnyav.
Txheej thickness: cov tuab dua txheej txheej, cov tuab ntawm txheej tiv thaiv, thiab huab cua zoo dua feem ntau yog. Lub thickness ntawm sab pem hauv ntej txheej feem ntau yog tshaj 20μm, thiab qhov ua tau zoo tshaj yuav mus txog 25μm lossis siab dua.
Txheej Txheej Zoo (cob, muaj xim ntxiv): qhov zoo thiab tsim cov ntsiab lus fluorizer (UV stabilizer qib) ncaj qha cuam tshuam rau kev ua tau zoo kawg nkaus.
Siv ib puag ncig: Coastal ntsev thaj chaw, thaj chaw uas muaj cov pa phem loj, thiab cov chaw muaj txiaj ntsig zoo dua rau huab cua tiv thaiv thiab ua kom sai.
Kev Txhim Kho thiab Kev Txij Nkawm: Zam kev teeb tsa (xyuas kom muaj kev khawb, kom huv si) thiab kev tu thiab tu nws cov huab cua tiv taus lub neej.
5.Qhov yog qhov kev pabcuam lub neej ntawm cov xim-coated galvanized steel kauj?
Cov xim zoo xim-txheej li PVDF txheej txheem (xws li cov xim pvdf) tuaj yeem tswj hwm xim thiab ci tiv thaiv corrosion rau 15-30 xyoo lossis tseem ntev dua nyob rau hauv cov huab cua tsawg los yog puag ncig.
Tus tsim lub neej ntawm cov txheej txheem polyester txheej txheem hauv ib puag ncig ib puag ncig feem ntau yog ib puag ncig 7-15 xyoo.
Lub neej tiag tiag yuav sib txawv heev nyob ntawm cov ntsiab lus saum toj no (tshwj xeeb yog ib puag ncig thiab txheej ua kom zoo).
