Z100-Z140 yog haum rau luv luv-lub sij hawm los yog tsawg-corrosion ib puag ncig, Z180-Z275 yog haum rau kev tiv thaiv corrosion mus sij hawm ntev
Xaiv cov zinc txheej raws li kev siv lub tsev
(1) Lub ru tsev / phab ntsa (warehouse, Hoobkas, tsev cog khoom)
Pom zoo zinc txheej: Z120-Z180
Yog vim li cas:
Nyob rau hauv ib txwm huab cua (tsis muaj zog acid nag, ntsev tsuag), nws tuaj yeem ua tau raws li kev tiv thaiv kev tiv thaiv -corrosion yuav tsum tau 10-15 xyoo.
Tus nqi qis thiab tsim nyog rau cov haujlwm uas muaj peev nyiaj tsawg.
(2) Civil vaj tsev (chaw nyob, tsev lag luam)
Pom zoo zinc txheej: Z140-Z200
Yog vim li cas:
Ob qho tib si zoo nkauj thiab durability yuav tsum tau muab rau hauv tus account. Ib txheej zinc uas nyias dhau yuav yooj yim xeb thiab cuam tshuam rau cov tsos.
Yog tias nws nyob hauv thaj chaw ntub lossis nag, Z200 lossis siab dua yog pom zoo.
(3) Ib puag ncig corrosive heev (nrog ntug dej hiav txwv, thaj chaw muaj kev lag luam)
Pom zoo zinc txheej: Z275 lossis galvanized aluminium (AZ150)
Yuav ua li cas prolong lub zinc txheej lub neej ntawmxwm 51dgalvanized kauj?
Xaiv ib txheej zinc tuab: Xaiv Z275 lossis galvanized zinc (AZ150) rau qhov chaw hnyav
Standardized installation: Siv galvanized / stainless hlau fasteners kom tsis txhob muaj kev puas tsuaj rau cov zinc txheej
Txhim kho kev tiv thaiv: Siv cov tshuaj tiv thaiv- xeb xim lossis xim txheej rau siab - cov cheeb tsam corrosion, thiab cov zinc galvanized yog nyiam nyob rau hauv ntug dej hiav txwv
Kev saib xyuas tsis tu ncua: Ntxuav qhov chaw nrog dej txhua xyoo thiab kho cov khoom puas hauv lub sijhawm
Dab tsi yog qhov txawv ntawm DX51D steel kauj thiab stainless hlau?
|
Nta |
DX51D galvanized hlau |
Stainless hlau |
|
|
Cov khoom siv hauv paus |
Tsawg carbon steel (hlau + carbon) |
Hlau-raws li alloy (muaj chromium Ntau dua lossis sib npaug li 10.5%, tuaj yeem muaj nickel thiab molybdenum) |
|
|
Kev kho saum npoo |
Kub dip galvanized (zinc txheej tiv thaiv) |
Ntuj tsim passive chromium oxide zaj duab xis (Cr₂O₃) |
|
|
Corrosion kuj |
Nruab nrab (nyob ntawm zinc txheej thickness) |
Muaj zog heev (tshwj xeeb tshaj yog 316 muaj molybdenum, resistant rau ntsev tsuag / kua qaub thiab alkali) |
|
|
Lub zog |
Tensile zog 270-500MPa |
Siab dua (304 stainless hlau txog 520-750MPa) |
|
|
Kev ua tau zoo |
Yooj yim rau stamp thiab khoov (zinc txheej yuav tawg) |
High hardness, tshwj xeeb cov cuab yeej yuav tsum tau (yooj yim ua hauj lwm harden) |
|
|
Kev ua neej nyob |
10-20 xyoo (nyob ntawm zinc txheej thiab ib puag ncig) |
Ntau tshaj 30 xyoo (hauv qhov chaw tsim nyog) |
