PPGI / prepainted galvanized steel kauj / ntawv hlau vov tsev yob

Advantage:

1.Anticorrosion durability

Cov xim coated phaj muaj cov nyhuv ntawm daim iav txheej. Thaum nws tau ntxiv rau lub siab rau cov menyuam hauv cov txheej txheem ntawm cov xim phaj, cov yeeb yaj kiab tiv thaiv yog txuas nrog ntau dua rau cov phaj saum npoo, uas tsis tsuas yog cuam tshuam rau kev khoov thiab lwm cov txheej txheem ua, tab sis kuj tuaj yeem tiv thaiv cov phaj saum npoo ntawm kev puas tsuaj. nyob rau hauv cov txheej txheem ntawm kev ua thiab sib dhos. Qhov adhesion ntawm qhov chaw muaj zog dua, thiab cov kav ntev yog qhov zoo dua, thiab yuav tsis muaj kev sib tsoo, tawg thiab tawg tom qab siv lub sijhawm ntev Cov teeb meem xws li spalling thiab lwm cov hmoov txau cov phaj yog ib qho yooj yim los tshwm, thiab tuaj yeem tswj tau nruj me ntsis raws li cov khoom siv. cov kev xav tau ntawm cov neeg siv khoom.

2.Tus txheej txheem tswj hwm

Lub tuam txhab tau dhau IS09001, gbat24001, gba28001 daim ntawv pov thawj zoo, tsim thiab txhim kho cov txheej txheem kev ruaj ntseg zoo. Raws li kev ua tiav ntawm qhov kev lees paub zoo, muaj cov txheej txheem ua tiav los ntawm kev txiav txim mus rau kev tsim khoom thiab xa khoom, thiab cov qauv hauv qab no tau ua nruj me ntsis.

• GB / T 12754 xim coated steel phaj thiab sawb
• JIS g3312 "pre coated kub dip galvanized steel ntawv thiab sawb"
• TS EN 10169-1 Nruam cov organic coated (coil coated) steel sheet khoom Tshooj 1: cov lus qhia dav dav (lus txhais, cov ntaub ntawv, kam rau ua, xeem txoj kev)
• TS EN 10169-2 "Nruam organic txheej (yob txheej) cov khoom lag luam steel phaj" ntu 2: tsim cov khoom siv sab nraud
• ASTM a755 "pre coated steel daim hlau rau sab nrauv siv nyob rau hauv cov tsev raws li kub-dip hlau coated daim hlau thiab ua los ntawm yob txheej txheej txheem"

3.Substrate

Cov xim coated substrate feem ntau suav nrog cov ntawv txias dov, ntawv galvanized thiab aluminized zinc ntawv. Qhov saum npoo ntawm cov khaub thuas dov substrate xim coated daim ntawv yog du thiab muaj kev ua haujlwm zoo, uas yog tsim rau cov tsev nyob sab hauv lossis cov khoom siv hauv tsev. Ntxiv nrog rau qhov zoo corrosion kuj ntawm txheej txheej, zinc txheej kuj muaj qhov zoo tiv thaiv corrosion ntawm lub substrate, thiab kev tiv thaiv ntawm ntug txiav yog zoo dua li lwm hom substrate. Cov txheej txheej ntawm cov xim coated board yog du thiab zoo nkauj; Qhov hnyav ntawm zinc txheej tuaj yeem txiav txim siab raws li koj xav tau.

Tnws process flow

Xim coated steel phaj feem ntau yog cov hlau galvanized, GL tom qab kev kho deg ntawm lawv qhov chaw coated nrog ib co thickness ntawm cov nplaum txheej los yog txheej ntawm cov organic zaj duab xis, tom qab kho, ua ib tug xim phaj, nrog zoo heev corrosion kuj, molding, kho kom zoo nkauj nyob rau hauv lub tsev. , cov khoom siv hauv tsev, lub teeb kev lag luam, kev thauj mus los thiab lwm yam kev lag luam dav siv los ua cov khoom siv zoo tagnrho.
