Galvalume steel kauj
Galvalume Steel Chev yog cov khoom siv hlau ua los ntawm cov ntawv txias- dov los yog kub- dov steel los xij. Los ntawm kev kub ntxhov tas mus li- txheej txheej txheej txheej, txheej txheej txheej txheej txheej txheej ntawm aluminium, zinc, thiab ib qho me me ntawm silicon yog tso rau saum npoo ntawm substrate. Ua ke qhov zoo ntawm txhuas thiab zinc, nws muaj kev tiv thaiv corrosion zoo heev thiab kev ua haujlwm zoo, ua rau nws muaj txiaj ntsig zoo thiab kev lag luam corrosion-resistant steel.
Raws li lub hauv paus rau galvanized steel kauj, lub substrate feem ntau yog ua los ntawm siab -zoo txias- dov los yog kub - dov steel. Txias-rolled substrates muab ib tug du nto thiab siab thickness raug, ua rau lawv haum rau daim ntaub ntawv uas yuav tsum tau siab tsos thiab machining precision. Kub- dov substrates muab lub zog siab dua thiab tus nqi qis, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau lub zog siab tab sis tsis xav tau ntau dua.
Txheej:Cov txheej yog ib feem tseem ceeb ntawm galvanized steel kauj qhov kev tiv thaiv corrosion thiab feem ntau yog ua los ntawm txhuas (55%), zinc (43.4%), thiab silicon (1.6%). Qhov sib piv alloy no tau raug tsim los ntawm kev tshawb fawb. Qhov sib ntxiv ntawm aluminium ho txhim khu kev tiv thaiv corrosion thiab siab -kub tsis kam ntawm txheej. Zinc muab kev tiv thaiv anodic sacrificial nyob rau hauv cov xwm txheej ntawm txheej puas. Silicon zoo inhibits cov tshuaj tiv thaiv ntawm aluminium-zinc alloy ntawm qhov kub thiab txias, tiv thaiv brittleness thiab ntxiv dag zog rau cov adhesion ntawm txheej thiab substrate.
Passivation Layer (Yeem):Qee cov galvanized steel coils kuj tsim txheej txheej passivation ntawm cov txheej txheej, feem ntau yog siv cov chromate lossis chromium-kev kho mob dawb. Cov txheej txheej passivation no ntxiv txhim khu kev tiv thaiv corrosion ntawm txheej, tiv thaiv oxidation thaum khaws cia thiab ua haujlwm. Nws kuj tseem ntxiv dag zog rau qhov adhesion ntawm cov txheej txheem tom ntej (xws li xim txheej) rau txheej txheej, nthuav dav daim ntawv thov ntau yam ntawm galvanized steel coils.
- Core Performance Advantages ntawm Galvanized Steel Chev - Zoo Corrosion Resistance
Qhov kev tiv thaiv corrosion ntawm galvanized steel coils yog ib qho ntawm lawv cov khoom zoo tshaj plaws, deb tshaj li cov tsoos kub -dip galvanized steel coils.
Barrier Protection: The aluminum in the coating forms a dense aluminum oxide film on the surface of the steel coil. Cov yeeb yaj kiab ruaj khov no zoo thaiv kev sib cuag ntawm cov pa oxygen, noo noo, carbon dioxide, thiab lwm yam corrosive media, ua haujlwm zoo li cov ntaub thaiv npog rau lub substrate, thaum kawg ua kom corrosion.
Sacrificial Anodic Protection: Thaum lub txheej yog khawb los yog puas, nthuav tawm lub substrate, zinc nyob rau hauv lub txheej preferentially undergoes electrochemical corrosion, muab sacrificial anodic tiv thaiv thiab tiv thaiv corrosion. Qhov kev tiv thaiv "tus kheej- kho" qhov no ua rau lub neej ntev ntawm cov hlau kauj.
Ntsev Txau thiab Acid Rain Resistance: Galvalume steel coils ua tau zoo tshwj xeeb hauv thaj chaw ntug dej hiav txwv nrog ntsev tsuag los yog hauv cov chaw lag luam uas muaj kua qaub ntau heev. Kev ntsuam xyuas tau pom tias lawv cov tshuaj tsw qab ntsev yog 3-5 npaug ntawm qhov kub-dip galvanized steel coils. Hauv kev kuaj tshuaj ntsev nruab nrab, lawv tuaj yeem tiv taus ntau dua 1,000 teev yam tsis muaj xeb liab. Lawv kuj zoo tiv taus cov kua qaub nag nrog pH ntawm 4.0-6.0, txo qhov kev puas tsuaj corrosion.
