Kub Dipped Prepainted Galvanized Xim Zinc Coated PPGI PPGL Prepainted Steel Chev

♦ PPGI coil substrate kev faib tawm

1. Kub dip galvanized substrate
Cov khoom tau los ntawm txheej txheej organic ntawm cov ntawv kub-dip galvanized steel yog cov ntawv kub-dip galvanized xim-coated.Ntxiv rau qhov kev tiv thaiv ntawm zinc, cov organic txheej rau ntawm qhov chaw ntawm cov ntawv kub-dip galvanized xim-coated kuj plays lub luag hauj lwm ntawm rwb thaiv tsev thiab kev tiv thaiv, tiv thaiv xeb, thiab kev pab cuam lub neej yog ntev tshaj li ntawm kub-dip. galvanized ntawv.Cov ntsiab lus zinc ntawm kub-dip galvanized substrate feem ntau yog 180g / m2 (ob tog), thiab qhov siab tshaj plaws galvanized tus nqi ntawm kub-dip galvanized substrate rau lub tsev sab nrauv yog 275g / m2.

2.Kub-dip Al-Zn substrate
Cov ntawv kub-dip galvanized steel ntawv (55% Al-Zn) yog siv los ua cov txheej txheej tshiab, thiab cov ntsiab lus ntawm txhuas thiab zinc feem ntau yog 150g / ㎡ (ob sab).Kev tiv thaiv corrosion ntawm kub-dip galvanized ntawv yog 2-5 npaug ntawm cov ntawv kub-dip galvanized.Kev siv tsis tu ncua lossis sib cuam tshuam ntawm qhov kub txog li 490 ° C yuav tsis ua rau oxidize lossis tsim cov nplai.Lub peev xwm los cuam tshuam cov cua sov thiab lub teeb yog 2 npaug ntawm kub-dip galvanized steel, thiab qhov kev xav tau ntau dua 0.75, uas yog cov khoom siv hauv tsev zoo tshaj plaws rau kev txuag hluav taws xob.

3.Electro-galvanized substrate
Cov ntawv electro-galvanized yog siv los ua cov substrate, thiab cov khoom tau los ntawm txheej cov xim organic thiab ci yog cov ntawv electro-galvanized xim-coated.Vim tias zinc txheej ntawm daim ntawv electro-galvanized yog nyias, zinc cov ntsiab lus ntawm cov ntawv electro-galvanized feem ntau yog 20/20g / m2, yog li cov khoom no tsis haum rau kev siv.Ua phab ntsa, ru tsev, thiab lwm yam sab nraum zoov.Tab sis vim nws cov tsos zoo nkauj thiab kev ua tau zoo heev, nws tuaj yeem siv rau hauv cov khoom siv hauv tsev, suab, steel rooj tog, kho kom zoo nkauj sab hauv, thiab lwm yam.

♦ PPGI / PPGL coil substrate yam ntxwv

Kub-dip galvanized substrate:

Lub nyias steel phaj yog immersed nyob rau hauv ib tug molten zinc da dej los ua ib txheej ntawm zinc adhere rau saum npoo.Qhov no galvanized phaj muaj zoo adhesion thiab weldability ntawm txheej.

Kub-dip Al-Zn substrate:

Cov khoom yog plated nrog 55% AL-Zn, muaj kev ua haujlwm zoo tiv thaiv corrosion, thiab nws lub neej kev pabcuam yog ntau tshaj plaub npaug ntawm cov hlau galvanized zoo tib yam.Nws yog ib qho kev hloov khoom ntawm galvanized ntawv.

Electro-galvanized substrate: 

Cov txheej yog thinner, thiab nws cov corrosion kuj tsis zoo li cov kub-dip galvanized substrate.

♦ PPGI coil khoom nta

(1) Nws muaj qhov ua tau zoo, thiab nws qhov kev tiv thaiv corrosion yog ntev dua li ntawm cov hlau galvanized;

(2) Nws muaj cov cua kub zoo thiab tsis tshua muaj kev cuam tshuam ntawm qhov kub thiab txias dua li cov hlau galvanized;

(3) Nws muaj thermal reflectivity zoo;

(4) Nws muaj kev ua tau zoo thiab kev ua haujlwm zoo ib yam li cov ntawv hlau galvanized;

(5) Nws muaj kev vuam zoo.

(6) Nws muaj tus nqi zoo-kev ua tau zoo, kev ua haujlwm ruaj khov thiab tus nqi sib tw heev.Yog li ntawd, txawm tias cov kws tsim vaj tsev, engineers lossis cov tuam txhab tsim khoom tau siv dav hauv cov tsev lag luam, cov qauv hlau thiab cov chaw pej xeem, xws li cov qhov rooj tsheb, cov kav dej thiab cov ru tsev.

♦ Ppgi coil daim ntawv thov

Ppgi coils yog lub teeb, zoo nkauj thiab muaj cov khoom zoo tiv thaiv corrosion, thiab tuaj yeem ua tiav ncaj qha.Cov xim feem ntau muab faib ua grey-dawb, dej hiav txwv-xiav thiab cib liab.Lawv tsuas yog siv hauv kev tshaj tawm, kev tsim kho, khoom siv hauv tsev, khoom siv hluav taws xob, rooj tog zaum thiab kev thauj mus los.Kev lag luam.
