Kev kho dua tshiab hauv Steel Yeeb Nkab Anticorrosion Technology Tiv thaiv kev nyab xeeb thiab kev ua neej nyob ntawm kev thauj mus los
Hauv petrochemical, dej hauv nroog, thiab kev thauj mus los ntawm cov roj av, cov kav hlau, uas yog cov tsheb thauj mus los tseem ceeb, tau raug cuam tshuam los ntawm ntau yam kev sib tw, suav nrog av corrosion, media yaig, thiab atmospheric oxidation. Cov ntaub ntawv qhia tau hais tias qhov nruab nrab kev pab cuam lub neej ntawm cov kav hlau tsis kho yog tsawg dua tsib xyoos, thaum cov txheej txheem kev kho mob tuaj yeem txuas ntxiv mus rau ntau dua 20 xyoo. Nrog kev txhim kho kev lag luam thiab ua kom muaj kev tiv thaiv ib puag ncig, steel yeeb nkab anticorrosion thev naus laus zis tau hloov zuj zus los ntawm kev tiv thaiv ib txheej mus rau theem tshiab ntawm kev tiv thaiv lub neej tag nrho suav nrog "cov khoom hloov kho dua tshiab, kev ua kom zoo dua qub, thiab kev saib xyuas ntse."
Tam sim no, mainstream steel yeeb nkab anticorrosion technologies muab ntau yam kev sib txawv ntawm cov tshuab ua kom haum rau cov kev thov tshwj xeeb. Hauv cov kav dej faus, 3PE (peb-txheej polyethylene txheej) anti-corrosion coatings yog cov kev daws teeb meem rau cov roj thiab cov kav dej ntev ntev vim lawv zoo heev rau cov av kev ntxhov siab thiab cathodic disbonding. Lawv cov qauv sib xyaw, suav nrog cov hmoov epoxy puag, cov nplaum nruab nrab, thiab txheej txheej polyethylene, muab ob qho tib si corrosion thiab kev tiv thaiv. Rau cov kua qaub thiab alkaline pipelines hauv kev lag luam chemical, fluorocarbon coatings thiab yas hauv ob sab phlu muaj qhov zoo. Cov yav tas los leverages cov tshuaj inertness ntawm fluororesins los tiv thaiv heev corrosive xov xwm, thaum lub sij hawm tom kawg lub cev cais cov khoom thauj los ntawm cov yeeb nkab steel nws tus kheej los ntawm txheej phab ntsa sab hauv nrog cov ntaub ntawv xws li polyethylene thiab polytetrafluoroethylene. Tsis tas li ntawd, kub-dip galvanizing yog dav siv nyob rau hauv me me corrosive ib puag ncig xws li cov dej hauv nroog thiab cov kav dej thiab cov qauv hlau txhawb nqa vim nws cov nqi qis thiab yooj yim installation. Lub sacrificial anodic nkaus ntawm zinc txheej muab kev tiv thaiv electrochemical ntev ntev rau cov yeeb nkab steel.
Kev hloov kho thev naus laus zis thiab cov txheej txheem kev tsim kho tshiab yog tsav kev txhim kho hauv cov yeeb nkab steel hlau los tiv thaiv corrosion. Cov txheej txheem kev pleev xim ib txwm siv, vim muaj teeb meem xws li cov txheej txheem tsis sib xws thiab cov adhesion tsis zoo, tau maj mam hloov los ntawm cov kab ntau lawm. Tam sim no mainstream electrostatic spraying thiab airless spraying technologies tuaj yeem ua tiav txheej thickness kam rau ua nyob rau hauv ± 5%. Nyob rau hauv lub tshav pob ntawm cov ntaub ntawv los tiv thaiv corrosion, environmentally friendly water-based epoxy coatings and graphene-modified anti-corrosion coatings are majly replaces solvent-based coatings, txo VOC emissions while improve the coating the weather resistance and wear resistance. Nyob rau tib lub sijhawm, cov kev soj ntsuam ntse tau pib ua ke rau hauv cov txheej txheem tiv thaiv corrosion. Cov kav hlau hlau hauv qee qhov haujlwm tseem ceeb tam sim no tau nruab nrog cov khoom siv corrosion. Cov sensors khaws cov khoom siv hluav taws xob tam sim no thiab cov txheej txheem kev puas tsuaj los ntawm cov raj xa dej sab nrauv, ua rau muaj kev ceeb toom ntxov ntawm kev pheej hmoo corrosion tsis ua hauj lwm thiab kev kho kom raug.
Rau cov yeeb nkab steel los tiv thaiv corrosion, kev pom zoo kev lag luam yog "30% cov ntaub ntawv, 70% kev tsim kho." Ua ntej kev tsim kho, cov yeeb nkab steel nto yuav tsum tau sandblasted kom tshem tawm xeb thiab xyuas kom meej qhov roughness ntawm Sa2.5 lossis siab dua. Qhov kev kho no kuj tshem tawm impurities xws li roj, nplai, thiab lwm yam impurities, paving txoj kev rau txheej adhesion. Thaum lub sij hawm tsim kho, txheej thickness, curing kub, thiab lub sij hawm yuav tsum tau nruj me ntsis tswj kom tsis txhob muaj qhov tsis xws luag xws li pinholes thiab txheej to. Tom qab ua tiav, qhov kev tiv thaiv corrosion yuav tsum tau txheeb xyuas los ntawm cov txheej txheem xws li kev kuaj lub txim thiab kuaj adhesion. Tsuas yog los ntawm kev tsim cov txheej txheem kaw, kaw lub voj voog uas suav nrog "kev xaiv cov khoom siv - kev kho saum npoo - kev tsim kho thiab kev tswj hwm - kev tu tom qab" tuaj yeem ua tus nqi mus sij hawm ntev ntawm cov yeeb nkab steel los tiv thaiv corrosion tau tiag tiag.
Nrog rau kev nce qib ntawm "dual carbon" cov hom phiaj thiab ua kom muaj kev ruaj ntseg hauv kev lag luam, steel yeeb nkab los tiv thaiv corrosion technology yuav txuas ntxiv mus rau kev cog qoob loo, muaj txiaj ntsig zoo dua, thiab kev txawj ntse ntau dua. Nyob rau hauv lub neej yav tom ntej, cov ntaub ntawv tshiab los tiv thaiv corrosion uas ua ke nrog cov khoom siv roj carbon tsawg nrog kev tiv thaiv mus ntev, nrog rau kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv uas sib koom ua ke digital ntxaib thev naus laus zis, yuav dhau los ua qhov tseem ceeb hauv kev lag luam tshawb fawb thiab kev tsim kho tseem ceeb. Cov no yuav muab cov ntaub thaiv tiv thaiv kev nyab xeeb rau ntau yam kev lag luam kav dej thiab pab txhawb rau kev ua haujlwm zoo ntawm cov txheej txheem.
