Hauv luv, xeb puas rauxim-coated steel daim hlauFeem ntau yog tshwm sim los ntawm rusty cam khwb cia hlau qhov chaw, xws li rusty steel ntsia hlau thiab xov hlau ntog ntawm cov xim-coated tuab steel daim hlau, thiab xim-coated, tuab steel phaj nto uas tau coated rau ib lub sij hawm. kev puas tsuaj tshwm sim. Rust yog ib yam kab mob sib kis uas piav txog cov hlau castings. Qhov no yog vim xeb yog honeycomb-zoo li tus thiab tuaj yeem zom tau yooj yim dej. Lub zom zawg xeb yuav ua kom lub corrosion ntawm cam khwb cia hlau qhov chaw. Lub corrosion ntawm cam khwb cia hlau adheres rau cov xim-coated tuab steel phaj, ua rau corrosion ntawm cov xim-coated coil tuab steel phaj.
kub
Cov txheej yuav softer, thiab corrosive cov kuab tshuaj yog yooj yim rau adhere thiab nkag mus rau hauv lub substrate. Cov ntsiab lus ntawm cov pa oxygen hauv dej yuav nce ntxiv hauv qhov kub thiab txias, thiab tus nqi corrosion yuav nrawm ntawm qhov kub thiab txias.
ib puag ncig humidity
Substrate corrosion ntawm qhov txhab thiab ua kev puas tsuaj yog electrochemical corrosion, thiab cov av noo tsawg yuav tsis yooj yim tsim lub cell (xws li electrochemical circuit).
Qhov kub thiab txias
Qhov kub sib txawv loj ua rau nws yooj yim rau condensation rau daim ntawv, tsim cov xwm txheej rau galvanic corrosion ntawm cov hlau raug. Tsis tas li ntawd, qhov sib txawv ntawm qhov kub thiab txias kuj ua rau kub kub thiab txias deformation ntawm txheej txheej, uas yuav ua rau kom cov laus thiab xoob ntawm txheej, thiab cov kuab tshuaj sab nraud tuaj yeem nkag mus rau hauv cov substrate yooj yim.
hnub ci
UV ultraviolet spectrum yog ib qho hluav taws xob ntau zaus, uas muaj kev cuam tshuam ntau dua li lub zog qis. X-rays muaj cov nyhuv nkag mus, thiab gamma rays tuaj yeem rhuav tshem cov tshuaj lom neeg thiab tsim cov ions dawb, uas ua rau tuag taus rau cov organic teeb meem. Yog li ntawd, nws tuaj yeem pom los ntawm cov saum toj no tias lub hnub ci teev thiab lub zog cuam tshuam rau kev ruaj ntseg ntawm cov txheej txheem, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj zog ultraviolet lub teeb.
nag lossis daus
Cov dej nag nrog cov kua qaub siab yuav muaj tseeb corrode steel. Txawm li cas los xij, nag lossis daus muaj ob qho txiaj ntsig. Rau cov phab ntsa panels thiab ru tsev panels nrog ib tug loj txoj kab nqes piv, nws muaj peev xwm ntxuav lub nto ntawm steel phaj thiab ntxuav tawm nto corrosion. Txawm li cas los xij, rau lub ru tsev panels nrog qhov qis qis qis thiab cov kav dej tsis zoo, Qhov chaw, qhov dej nag ntau dua, qhov yuav ua rau muaj kev xeb ntxiv.
Cua zaus
Zoo li dej, thiab feem ntau txuam nrog nws, nws yog ib qho kev sim rau cov pob qij txha ntawm cov ntaub ntawv vim cua tuaj yeem ua rau cov pob qij txha xoob thiab nag lossis daus tuaj yeem nkag mus rau sab hauv ntawm lub tsev.
Corrosive tshuaj
Corrosion sediments xws li chloride ions, sulfur dioxide, thiab lwm yam tuaj yeem ua kom corrosion. Xws li sediments feem ntau tshwm sim los ntawm ntug hiav txwv dej thiab thaj chaw uas muaj kuab paug loj heev (xws li cov nroj tsuag fais fab, cov nroj tsuag smelting, thiab lwm yam).
koom
Feem ntau muaj ntau yam xws li ncej puab, undercut thiab buckle. Cov khoom xaiv ntawm fasteners xav kom nws corrosion kuj zoo dua li cov xim hlau daim hlau. Txwv tsis pub, raws li lub hauv paus ntsiab lus ntawm cathode loj thiab me me anode, kev sib txuas yuav corrode thiab hnav sai sai. Qhov thib ob, cov khoom zoo ntawm cov sealant yuav tsum tau ua kom ntseeg tau.
mus rau
Txoj kev taw qhia thiab txoj kab nqes ntawm ib lub tsev cuam tshuam rau cov sij hawm ntawm lub hnub ci thiab yog li qhov ua tau ntev ntawm cov txheej. Qhov piv ntawm txoj kab nqes kuj tseem cuam tshuam rau lub sij hawm daws teeb meem ntawm cov kuab tshuaj corrosive lossis hmoov av ntawm cov phaj hlau.
