Txhawm rau txhim kho corrosion kuj ntawm cov yeeb nkab steel, qhov nruab nrab steel yeeb nkab yog galvanized. Galvanized steel kav muab faib ua ob hom: kub, galvanized thiab electroplating.
Qhov kub-dip galvanized thiab galvanized txheej yog tuab, tus nqi ntawm galvanizing yog tsawg, thiab qhov saum npoo tsis du heev.
Nominal phab ntsa thickness: mm20252.8, 3.2, 3.5, 3.8, 4.0, 4.5.
Coefficients: C1.064, 1.051, 1.045, 1.040, 1.036, 1.034 \ 1.032, 1.028.
Lus Cim: Cov khoom siv hlau hlau yog cov cim tseem ceeb los xyuas kom meej qhov kev ua tau zoo kawg (kev ua haujlwm zoo) ntawm cov hlau. Nws nyob ntawm cov tshuaj muaj pes tsawg leeg thiab thermal kho system ntawm steel. Nyob rau hauv cov qauv steel yeeb nkab, raws li kev siv sib txawv, kev ua tau zoo ncab (lub zog tensile, yield zog los yog yield point, elongation point), hardness, toughness indicators, thiab high-temperature kev ua tau zoo ntawm cov neeg siv. Tus naj npawb ntawm galvanized yeeb nkab steel: Q215A; Q215B; Q235A O235B
Galvanized steel yeeb nkab yog vuam steel yeeb nkab nrog armal immersion lossis electroplating txheej ntawm qhov chaw. Txhawm rau txhim kho corrosion kuj ntawm cov yeeb nkab steel, cov yeeb nkab steel (dub yeeb nkab) yog galvanized. Dalgrus yog hu ua dub hlau kav, thiab galvanized yog hu ua dawb hlau kav. Galvanizing tuaj yeem ua rau muaj kev tiv thaiv corrosion ntawm cov kav hlau thiab txuas ntxiv lub neej kev pab cuam.
Galvanized steel kav tau muab faib ua cov kav dej txias galvanized thiab kub-dip galvanized steel kav. Tam sim no, kub-dip galvanized steel kav yog dav siv rau hluav taws, hluav taws xob thiab kev loj. Ntxiv nrog rau cov kav dej ntawm cov dej tsis tshua muaj siab xws li dej, roj, thiab roj, nws kuj yog siv los ua cov kav dej roj thiab cov kav dej rau kev lag luam roj, tshwj xeeb tshaj yog cov roj marine, thiab cov khoom siv tshuaj coking roj cua sov, condensed cooler, thiab thee distillation roj pauv pauv Lub raj ntawm lub twj paj nruag, nrog rau kev txhawb nqa khib ntawm trestle yeeb nkab yeeb nkab thiab lub qhov mining.
