Xim Coated Coil Substrate Classification
Kub-dip Galvanized Substrate
Cov khoom tau los ntawm txheej cov xim pleev xim rau ntawm cov ntawv kub-dip galvanized steel yog hu ua kub-dip galvanized xim coated nplooj ntawv. Ntxiv rau qhov kev tiv thaiv ntawm zinc, cov organic txheej ntawm qhov chaw kuj muab cov rwb thaiv tsev thiab tiv thaiv xeb, ua rau lub neej ua haujlwm ntev dua piv rau cov ntawv kub-dip galvanized. Cov ntsiab lus zinc ntawm kub-dip galvanized substrates feem ntau yog 180g / m2 (ob tog), nrog rau qhov siab tshaj plaws ntawm 275g / m2 rau kev siv sab nrauv.
Kub-dip Al-Zn Alloy Substrate
Siv cov ntawv kub-dip Al-Zn alloy steel los xij (55% Al-Zn) ua cov txheej txheej tshiab, cov ntsiab lus txhuas-zinc yog 150g/㎡ (ob sab). Qhov corrosion kuj ntawm kub-dip Al-Zn alloy nplooj ntawv yog 2-5 lub sij hawm ntawm kub-dip galvanized los xij. Lawv tuaj yeem siv tsis tu ncua lossis sib cuam tshuam ntawm qhov kub txog 490 degree yam tsis muaj oxidation hnyav lossis oxide scale tsim. Lawv lub peev xwm los cuam tshuam cov cua sov thiab lub teeb yog ob npaug ntawm cov ntawv kub-dip galvanized steel ntawv, nrog rau qhov muaj kev cuam tshuam ntau dua 0.75, ua rau lawv cov khoom siv hluav taws xob zoo tagnrho.
Electrogalvanized Substrate
Cov khoom tau los ntawm kev siv cov xim organic thiab ci rau ntawm cov ntawv hlau electrogalvanized yog hu ua electrogalvanized xim coated nplooj ntawv. Vim yog cov zinc txheej nyias ntawm cov ntawv electrogalvanized, feem ntau 20/20g / m2, cov khoom no tsis haum rau sab nrauv phab ntsa, ru tsev, thiab lwm yam. Txawm li cas los xij, nws khav theeb zoo nkauj thiab ua haujlwm zoo, ua rau nws zoo tagnrho rau cov khoom siv hauv tsev, suab. khoom siv, steel rooj tog, thiab kho kom zoo nkauj sab hauv.
Cov yam ntxwv ntawm Xim Coated Coil Substrates
Electrogalvanized Substrate: Muaj cov txheej txheej thinner thiab tsis zoo corrosion kuj piv rau kub-dip galvanized substrates.
Kub-dip Galvanized Substrate: Koom nrog rau cov nplooj ntawv nyias nyias hauv zinc molten kom ua raws li zinc txheej rau saum npoo. Hom ntawv galvanized no nthuav tawm cov xim zoo adhesion thiab weldability.
Kub-dip Al-Zn Alloy Substrate: Nta 55% Al-Zn txheej, muab tshwj xeeb corrosion kuj thiab lub neej kev pab cuam tshaj plaub zaug ntev dua li cov nplooj ntawv galvanized zoo tib yam. Nws yog ib qho khoom siv tom ntej uas hloov cov ntawv galvanized.
Khoom nta:
Zoo heev durability thiab corrosion kuj, nrog ib tug ntev lifespan piv rau galvanized steel los xij.
Kev ua haujlwm kub zoo, tsis tshua muaj xim ntawm qhov kub thiab txias piv rau galvanized steel los xij.
Zoo heev tshav kub reflectivity.
Sib piv cov txheej txheem thiab txheej txheej rau galvanized steel los xij.
Kev ua haujlwm vuam zoo.
Tus nqi-kev ua tau zoo sib piv, nrog kev ua haujlwm ruaj khov thiab tus nqi sib tw. Yog li ntawd, architects, engineers, thiab manufacturers dav siv Al-Zn alloy steel nplooj ntawv nyob rau hauv cov tsev lag luam, steel qauv, thiab pej xeem chaw xws li chaw nres tsheb qhov rooj, gutters, thiab ru tsev.
Hom Xim Coated Coil Coatings
Zoo adhesion, nplua nuj xim, ntau yam formability thiab sab nraum zoov durability, nruab nrab tshuaj tsis kam, thiab tus nqi qis.
Silicone-modified Polyester (SMP): Zoo heev hardness, hnav tsis kam, thiab kub tsis kam ntawm txheej zaj duab xis. Zoo sab nraud durability thiab chalking kuj, nruab nrab gloss tuav thiab yooj, thiab nruab nrab nqi.
High-Durability Polyester (HDP): Zoo heev xim tuav thiab UV tsis kam, superior sab nraum zoov durability thiab chalking kuj, muaj zog xim zaj duab xis adhesion, nplua nuj xim, thiab zoo heev nqi-kev ua tau zoo piv.
Polyvinylidene Fluoride (PVDF): Cov xim zoo nkauj thiab UV tsis kam, zoo heev sab nraum zoov durability thiab chalking kuj, zoo hnyav kuj, formability, thiab av kuj. Kev xaiv xim txwv thiab tus nqi siab.
