Galvalume steel yog cov ntawv carbon steel coated nrog aluminium-zinc alloy (55% Aluminium, 43.4% Zinc, 1.6% Silicon) los ntawm cov txheej txheem kub-dip, muab superior corrosion resistance, siab -kub oxidation tsis kam, thiab ntev -lub sij hawm durability. Nws ua raws li nws tus kheej- kho cov khoom tiv thaiv xeb ntawm cov npoo txiav, kav ntev li ob zaug ntev li galvanized steel ntawm cov tuab zoo sib xws, ua rau nws zoo tagnrho rau vov tsev, sab hauv, thiab cov khoom siv.
Galvalumefeem ntau yog siv los tiv thaiv hlau-raws li alloys uas nquag xeb. Galvalume-coated steel muaj peev xwm tiv taus oxidation zoo dua li cov pa roj carbon monoxide vim tias zinc thiab txhuas tiv thaiv cov hlau hauv ib puag ncig. Cov zinc kuj tseem yuav nkag siab oxidize ntau dua li cov hlau nws tiv tauj. Qhov no zoo ib yam li galvanized steel.

Qhov sib txawv tseem ceeb ntawm galvanizing thiab Galvalume yog galvalume yog kev sib xyaw ntawm zinc, aluminium, thiab silicon, thaum galvanizing yog 100% zinc. Kev pleev xim ntawm peb lub ntsiab lus hauv Galvalume txheej tsuas yog tshaj 50% txhuas, tsuas yog qis dua 50% zinc, nrog cov lej ntawm silicon.
Ib qho txiaj ntsig uas Galvalume muaj tshaj li cov khoom siv galvanized yog tias nws muaj peev xwm tiv thaiv tau zoo dua. Sij hawm dhau mus, Galvalume nyiam ua tau zoo dua li cov hlau galvanized, tshwj xeeb tshaj yog thaum raug dej los yog lwm yam kua uas tuaj yeem ua kom ceev cov txheej txheem oxidation. Txawm tias tom qab ob peb xyoo lawm, Galvalume-coated steel yuav tsis tshua muaj xeb dua li cov hlau galvanized.
Galvalume kuj tseem suav tias yog qhov zoo nkauj tshaj li kub -dipped galvanized cov ntaub ntawv.
Galvalume yog siv rau cov khoom siv kub -dipping txheej txheem. Yog li ntawd, Galvalume txheej muaj cov thicknesses zoo sib xws rau cov khoom kub -dipped galvanized. Lub thickness rau cov txheej txheem kub -dipping yog nyob ib ncig ntawm 1 mil tuab. Lub thickness tuaj yeem sib txawv me ntsis nyob ntawm cov txheej txheem txheej txheem. Yog tias cov txheej thicknesses ntawm Galvalume-coated steel thiab galvanized steel yog sib npaug, Galvalume steel feem ntau yuav outlasting lub galvanized ib, nyob ntawm seb ib puag ncig.

Q: 1. Galvalume Steel yog dab tsi?
A: Galvalume yog ib daim ntawv carbon steel coated nrog ib tug alloy ntawm 55% txhuas, 43.4% zinc, thiab 1.6% silicon. Cov txheej tshwj xeeb no ua ke nrog kev tiv thaiv kev tiv thaiv ntawm txhuas nrog kev tiv thaiv kev tiv thaiv ntawm zinc, muab kev ua haujlwm zoo dua piv rau cov qauv hlau.
Q: 2. Qhov txawv ntawm Galvalume (GL) thiab Galvanized (GI) yog dab tsi?
A: Qhov no yog qhov kev nug ntau tshaj plaws los ntawm cov neeg yuav khoom:
Txheej Txheej: Galvanized steel yog coated nrog 100% zinc, thaum Galvalume nta aluminium-zinc alloy.
Corrosion Resistance: Galvalume feem ntau kav ntev li 2 mus rau 4 npaug ntev dua li Galvanized steel nyob rau hauv feem ntau atmospheric tej yam kev mob.
Qhov tshwm sim: Galvalume muaj qhov smoother, me dua, thiab ntau yam xim hlau "spangle" (crystal qauv) piv rau cov flakes loj dua feem ntau pom ntawm Galvanized steel.
Q: 3. Lub neej ua haujlwm ntev npaum li cas ntawm Galvalume Steel?
A: Raws li ib puag ncig ib puag ncig, siab - Galvalume steel zoo muaj qhov perforation - tiv taus lub neej ntawm 20 txog 25 xyoo. Nws qhov tshwj xeeb tsis kam tiv thaiv xeb ua rau nws yog qhov kev xaiv tseem ceeb rau ntev - lub sij hawm sab nraum zoov infrastructure.
Q: 4. Galvalume Steel puas tuaj yeem pleev xim?
A: Yog. Galvalume yog ib qho zoo heev substrate rau Prepainted Galvalume (PPGL). Nws nto muab cov xim zoo adhesion. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub meej tias qhov chaw huv si thiab qhuav; Feem ntau, tsis muaj qhov nyuaj ua ntej - kev kho mob yog xav tau rau txheej txheej.
Q: 5. Nws ua haujlwm li cas hauv qhov chaw siab -kub?
A: Galvalume muaj cov cua kub zoo heev. Nws tuaj yeem tiv taus qhov kub txog li 315℃(600℃F) rau lub sijhawm ntev yam tsis muaj xim daj lossis oxidation. Qhov no ua rau nws zoo tagnrho rau cov khoom siv hauv qhov cub, cov kav dej chimney, thiab cov khoom siv dej kub.
Q: 6. Cov ntawv thov tseem ceeb ntawm Galvalume yog dab tsi?
A: Kev tsim kho: ru tsev, phab ntsa vaj huam sib luag, qhov rooj chav nres tsheb, thiab laj kab.
Cov khoom siv: Cov tub yees hauv qab phaj, cua txias tshuab, thiab microwave qhov cub hauv ob sab phlu.
Automotive: Mufflers thiab cov yeeb nkab tso cua sov tiv thaiv.
Kev Ua Liaj Ua Teb / Kev Lag Luam: Cov qoob loo qoob loo, cov qhov cua qhov cua, thiab cov khoom siv hluav taws xob sab nraum zoov.
Q: 7. Puas yog Galvalume haum rau tsiaj txhu lossis tsiaj vaj tsev?
A: Tsis pom zoo. Qhov no yog ib qho kev txwv tseem ceeb. Cov aluminium-zinc txheej degrades sai sai thaum raug ammonia (alkaline ib puag ncig) tsim los ntawm cov tsiaj pov tseg. Rau cov tsev txhab nyiaj lossis tsiaj txhu, hnyav-lub luag haujlwm Galvanized (GI) steel feem ntau yog qhov kev xaiv zoo dua.
Q: 8. Puas yog Galvalume muaj thermal reflectivity?
A: Yog. Galvalume muaj kev cuam tshuam kub kub (kwv yees . 65%–75%). Nws qhia txog qhov tseem ceeb ntawm lub hnub ci tshav kub, uas tuaj yeem txo cov nqi cua txias hauv tsev thaum lub caij ntuj sov. Nws suav hais tias yog lub zog-cov khoom siv "txias vov tsev" zoo.
Q: 9. Yuav ua li cas yog lub formability thiab weldability ntawm Galvalume?
A: Galvalume steel muaj kev ua tau zoo heev, tso cai rau nws yuav tsum tau khoov, stamped, thiab folded zoo ib yam li galvanized steel. Thaum nws yog weldable, vuam tsis tuaj yeem xav tau kev hloov kho vim yog cov ntsiab lus txhuas los xyuas kom muaj zog, huv si.
Q: 10. Vim li cas qee zaum cov pob dub tshwm ntawm Galvalume?
A: Yog tias Galvalume coils khaws cia hauv qhov chaw ntub dej, qhov cua tsis zoo, cov dej noo tuaj yeem nkag mus rau ntawm cov khaubncaws sab nraud povtseg, ua rau muaj tshuaj lom neeg hu ua "Black Rust" lossis "Wet Storage Stain." Txhawm rau tiv thaiv qhov no, nco ntsoov khaws cov khoom hauv qhov chaw qhuav thiab thov passivated (chromated) lossis oiled nto kho los ntawm cov chaw tsim khoom.
Raws li ib qho ntawm cov kws tshaj lij galvalume steel tuam ntxhab thiab cov muag khoom hauv Suav teb, peb tau tshwj xeeb los ntawm cov kev pabcuam zoo thiab cov nqi sib tw. Thov so assured mus yuav cov khoom zoo galvalume steel rau muag ntawm no los ntawm peb lub hoobkas. Tiv tauj peb rau pricelist thiab qauv dawb.
