Dab tsi yog Pre-painted Steel Chev?
Pre-painted steel kauj- tseem hu ua xim pleev xim rau steel ntawv lossis xim pleev xim hlau phaj- yog cov khoom siv xim hlau. Nws yog tsim los ntawm kev siv cov txheej txheem organic (xws li polyester lossis fluorocarbon) rau saum npoo ntawm cov ntaub ntawv nruj zoo li cov ntawv txias-cov ntawv hlau los yog kub-dip galvanized steel los xij. Nws sawv tawm rau kev tiv thaiv corrosion, zoo nkauj zoo nkauj, kev tsim kho yooj yim, thiab tus nqi -kev ua tau zoo, ua rau nws muaj kev tiv thaiv ib puag ncig hauv kev tsim kho, kev lag luam, thiab lwm yam.
Core Composition & Classification
Base Material Hom
Txias-cov khoom siv dov hauv paus: Tus nqi- zoo, haum rau qhov chaw qhuav hauv tsev (xws li, lub tsev khaws khoom sab hauv phab ntsa) nrog rau qhov nruab nrab corrosion kuj.
Kub-dip galvanized puag khoom: Zinc txheej thickness ranges ntawm 100-275g / ㎡, muaj zog corrosion kuj. Zoo tagnrho rau siv sab nraum zoov (xws li, Hoobkas sab nrauv phab ntsa, ru tsev).
Kub-dip galvanized- cov khoom siv hauv aluminium: Muab cov khoom tiv thaiv corrosion zoo ntawm zinc thiab txhuas, nrog rau kev tiv thaiv huab cua. Ua hauj lwm zoo nyob rau hauv corrosive ib puag ncig zoo li tej thaj chaw ntug hiav txwv dej los yog industrial zones.
Txheej Txheej Txheej
Polyester (PE) txheej: Sib npaug kev ua haujlwm thiab tus nqi, nrog qhov nruab nrab thermal rwb thaiv tsev. Kev pab lub neej ntawm 5-10 xyoo, haum rau lub tsev lub hnab ntawv.
Fluorocarbon (PVDF) txheej: huab cua zoo heev, acid-alkali tsis kam, thiab tsis-fading zog. Weatherproof rau 15-25 xyoo, zoo tagnrho rau high-end vaj tse los yog cov qauv nyob rau hauv ib puag ncig corrosive heev.
Silicone-hloov polyester (SMP) txheej: Poob ntawm PE thiab PVDF hauv kev ua tau zoo, nrog huab cua tsis zoo. Kev pab lub neej ntawm 8-15 xyoo, haum rau nruab nrab - mus rau - cov ntawv thov siab kawg.
PVDF + primer: Muab ob npaug rau- txheej txheej, xa sab saum toj -tier corrosion thiab stain kuj. Feem ntau siv nyob rau hauv cov tuam tsev landmark.
Key Performance Indicators
Corrosion kuj: Relies ntawm cov khoom siv zinc txheej thickness thiab txheej zoo. Withstands 500-3000 teev nyob rau hauv kev ntsuam xyuas ntsev tsuag, sib txawv heev los ntawm txheej txheej.
Huab cua tsis kam: PVDF txheej ua tau zoo hauv UV tiv thaiv thiab tiv thaiv -aging; PE txheej yuav ploj mus pom zoo nyob rau hauv muaj zog UV rays.
Mechanical zog: Tensile zog Ntau dua los yog sib npaug rau 270MPa, yield zog Ntau dua los yog sib npaug rau 235MPa. Nws tuaj yeem khoov, txiav, thiab txiav kom tau raws li ntau yam kev tsim kho.
Kho kom zoo nkauj rov hais dua: Muaj kev xaiv xim nplua nuj (hlau xiav grey, dej hiav txwv xiav, xim liab) thiab ua tiav (pav, embossed, frosted) kom phim cov kev xav zoo nkauj sib txawv.
