Lub teeb steel villa cov ntaub ntawv: feem ntau yog ua los ntawm lub teeb steel ntawv los ntawm cov khoom siv txias khoov los ua C-shaped lub teeb steel keel, los ntawm lub teeb steel keel los tsim cov pob txha ntawm lub tsev, hu ua lub teeb steel qauv tsev lossis lub teeb steel villa .
Lub zog ntawm steel yog hais txog hardness ntawm steel, tus nqi siab dua, lub zog muaj zog, lub zog kuj tseem hu ua yield zog, qee zaum tsis yog siab dua lub zog zoo dua, qee zaum xav txog kev ua yuav tsum xaiv ntau qib ntawm lub zog, xws li kev ua haujlwm tensile, siab zog steel yuav tawg.
Lub teeb steel txheej yog muab faib ua galvanized thiab aluminized zinc ob hom:
Galvanizing: ntau npaum li cas cov ntsiab lus, feem ntau saib tus nqi, lub teeb steel villas feem ntau siv zinc 275 grams thiab 300 grams, tus nqi yog cov ntsiab lus ntawm ib square tiam ntawm zinc, ntau dua cov ntsiab lus, lub thicker zinc txheej.
Galvanizing lub cev hloov pauv: Galvanizing raug thiab reacts nrog oxygen nyob rau hauv cov huab cua txhua xyoo puag ncig, thiab saum npoo yuav dub.
Aluminium thiab zinc plating: AZ150 rau luv luv, txhuas thiab zinc plating yog galvanized anticorrosion 2-6 zaug, txhuas thiab zinc plating keel ntev ntev liab qab nto tsis muaj xim hloov, xws li tshuaj lom neeg corrosion, lub cev cov tshuaj tiv thaiv tshwm sim nyob rau saum npoo ntawm keel. , tsim ntawm txhuas tiv thaiv zaj duab xis nyob rau saum npoo ntawm keel, kom cov tshuaj lom neeg sab nraud thiab keel sib cais, tiv thaiv lub cev keel khoom, tiv thaiv xeb.
G550 aluminized zinc feem ntau siv txhua yam khoom thiab lub cev tsis muaj raws li hauv qab no:
Lub npe yield zog elastic modulus bulk ntom ntom thermal expansion coefficient
G550 550MPa 2.06X105 N / hli 2 7.85g / cm3 1.2×10-5℃
Qhov kev tiv thaiv corrosion ntawm "aluminized zinc coil" los ntawm kev tiv thaiv kev tiv thaiv ntawm txhuas thiab kev tiv thaiv kev tiv thaiv ntawm zinc.Thaum zinc yog txi los tiv thaiv qhov txiav npoo, khawb, thiab khawb ntawm cov txheej, aluminium tsim ib txheej insoluble oxide uas ua haujlwm li ib qho barrier.Aluminized zinc alloy steel coils tau raug kuaj sab nraum zoov rau ntau tshaj 20 xyoo nyob rau hauv ntau yam atmospheric ib puag ncig, thiab nws tau raug pov thawj tias kev tiv thaiv kev tiv thaiv ntawm aluminized zinc steel los xij yog zoo dua li ntawm cov ntawv hlau galvanized.
Kub aluminized zinc steel phaj yog hom txias-kuav los tiag steel phaj nrog ntau lub zog thiab tuab specifications raws li cov khoom siv hauv paus.Nws yog pre-coated steel phaj tau los ntawm kub plating txheej ntawm Al-Zn txheej ntawm ob sab.Cov feem pua ntawm cov txheej txheem txheej yog li 55% Al (txhuas), 43.5% Zn (zinc), 1.5% Si (silicon).Combines Al lub cev tiv thaiv thiab electrochemical tiv thaiv feature, siab durability thiab zinc khoom muaj lub zog ntawm cov hlau substrate. thiab yas, thiab corrosion kuj ntawm lub txheej, nws muaj peev xwm tiv thaiv cov hlau substrate nyob rau hauv tsis muaj corrosion, nyob rau hauv tas li ntawd, nyob rau saum npoo ntawm shining nyiaj loading txoj cai nrog siab ornamental qauv, thiab muaj ib tug siab ntawm nyem.
G550 + AZ150 kev taw qhia kev ua haujlwm:
Thaum tshav kub kub kuj:
Lub tshav kub tsis kam ntawm aluminized zinc alloy steel phaj yog zoo dua li ntawm galvanized steel phaj, thiab nws yog resistant rau kub oxidation.Aluminized zinc tuaj yeem siv rau hauv qhov chaw kub kub txog li 315 degrees.
Reflexibility:
Aluminized zinc muaj qhov cuam tshuam siab, uas ua rau nws muaj kev cuam tshuam thermal; Lub thermal reflectivity ntawm aluminized zinc yog yuav luag ob zaug ntawm galvanized zinc, yog li nws tuaj yeem siv los ua cov qauv tseem ceeb ntawm lub tsev nyob rau hauv ib qho xwm txheej kom ua tiav lub zog txuag.
Aluminium plated zinc steel phaj kuaj:
Sib piv cov kev ntsuam xyuas ntawm coated steel phaj nyob rau hauv industrial cheeb tsam ntawm Pennsylvania, USA:
Aluminium zinc plated steel phaj tom qab 30 xyoo txog qhov tsis muaj xeb, qis-tsawg txias-tsim nyias-walled steel lub tsev yog lub ntsiab steel qauv yog tag nrho cov ntim rau hauv phab ntsa, yog li cov qauv tseem ceeb yuav siv tau rau ntau tshaj 100 xyoo.
Kev ruaj ntseg zoo:
Machinability: kom ua tau raws li qhov yuav tsum tau ua ntawm dov, stamping, dabtsi yog khoov thiab lwm yam kev ua haujlwm.
Corrosion kuj (piv nrog kub dip galvanized): kub dip galvanized steel phaj muaj corrosion kuj zoo heev, kev pab cuam lub neej yog tib txheej thickness ntawm zoo tib yam galvanized steel phaj 2-6 zaug.
Reflectance: lub peev xwm los cuam tshuam cov cua sov thiab lub teeb yog 2 npaug ntawm kub-dip galvanized steel phaj, thiab qhov kev xav tau ntau dua 0.70, uas zoo dua li 0.65 teev los ntawm EPA Energy Star.Nws yog cov khoom siv hluav taws xob zoo tshaj plaws hauv tsev.
Thaum tshav kub kub tsis kam: zoo tib yam kub dip galvanizing khoom feem ntau siv kub tsis tshaj 230℃, 250 ib℃yuav discolor, thiab aluminized zinc phaj yuav siv tau nyob rau hauv 315℃ib puag ncig rau lub sijhawm ntev yam tsis muaj xim tsis muaj xim.Cov xim hloov ntawm aluminium-zinc plated steel phaj kho los ntawm tshav kub passivation ntawm Baosteel yog tsawg dua li ntawm aluminium-plated steel phaj thiab aluminium-plated steel phaj tom qab 120 teev ntawm 300.℃.
