H nqaj ntu galvanized ss400
SS400 yog cov qauv siv dav hlau siv rau nws lub zog muaj zog muaj zog, zoo heev weldability, thiab tus nqi-ua hauj lwm zoo. Daim ntawv "H" yog hais txog nws daim ntawv hla kev hla, uas zoo ib yam li tsab ntawv "H" thiab muab cov khoom muaj peev txheej zoo thiab muaj kev ua tau zoo. Thaum Galvanized, cov hlau yog coated nrog ib txheej tiv thaiv ntawm zinc, ua rau nws haum nyob rau hauv ib puag ncig muaj xeb thiab corrosion yog kev txhawj xeeb.
Cov txheej txheem galvanizing cuam tshuam nrog cov txheej txheej nrog zinc, feem ntau dhau ntawm kub-dip galvanizing, qhov twg cov hlau yog raus hauv molten zinc ntawm kwv yees li {}} degree. Qhov no tsim ib txheej zinc ruaj khov (feem ntau 50-150 μm tuab, nyob ntawm cov lus qhia tshwj xeeb) uas yog metallurgically Bonds mus rau cov hlau saum npoo av, txhim kho nws corrosion tsis kam.
Galvanizing zoo
Corrosion Kuj: Cov txheej zincing ua raws li kev tiv thaiv kev ua kom tuag, tiv thaiv cov hlau hauv qab txawm tias qhov txheej txheej kos lossis puas. Hauv nroog ib puag ncig, galvanized ss400 galvanized h-nqaj yuav nyob ntev dua 50 xyoo tsis muaj kev saib xyuas loj heev, lawv tuaj yeem ua rau 20-30 xyoo.
Qhov xwm txheej tsis txaus: Metallurgical Bond ntawm Zinc thiab Steel ua kom muaj zog, ntev-ntev tiv thaiv txheej uas ua rau txhua yam kev puas tsuaj thaum siv kev thauj mus los thiab siv.
Tus nqi ua tau zoo: Galvanizing yog tus qauv tsawg tus nqi ntawm kev tiv thaiv corrosion ntau xws li cov hlau stainless lossis cov txheej txheem tshwj xeeb.
Cov txheej txheem tsim khoom
Substrate ntau lawm: SS400 galvanized steel yog tsim los ntawm kub dov, qhov twg cov billet yog rhuab rau ntau dua 1000 degree thiab tsim rau hauv H-nqaj siv cov zeb yob.
Cov kev kho deg: Lub H-Beams tau ntxuav kom tshem tawm cov impurities xws li xeb, roj lossis nplai, feem ntau yog los ntawm pickling lossis grit blasting.
Kub Dip Galvanizing: Cov kab mob H-nqaj tau muab tso rau hauv chav da dej ntawm Molten Zinc los ua ib qho chaw zoo nkauj zinc kom zoo nkauj. Tshaj dhau qhov zinc tau muab tshem tawm thiab cov kab teeb tau txias.
Kev kuaj thiab xov: Galvanized H-nqaj yog qhov zoo tshuaj xyuas rau txheej txheej txheej txheej ua ntej ntim khoom.
