Kev Txhim Kho Hauv Cov Yeeb Nkab Hlau Tiv Thaiv Kev Xeb Tiv Thaiv Kev Nyab Xeeb thiab Lub Neej Siv Tau Ntev ntawm Kev Thauj Mus Los Hauv Kev Lag Luam
Hauv cov chaw ua lag luam roj av, cov dej hauv nroog, thiab cov roj av, cov kav hlau, ua cov tsheb thauj mus los tseem ceeb, yeej ib txwm raug ntau yam teeb meem, suav nrog kev xeb av, kev xeb ntawm cov xov xwm, thiab kev xeb hauv huab cua. Cov ntaub ntawv qhia tau hais tias lub neej ua haujlwm nruab nrab ntawm cov kav hlau tsis kho yog tsawg dua tsib xyoos, thaum cov kev kho mob tiv thaiv xeb tus qauv tuaj yeem ntev mus txog ntau tshaj 20 xyoo. Nrog kev txhim kho kev lag luam thiab kev xav tau kev tiv thaiv ib puag ncig ntau dua, cov thev naus laus zis tiv thaiv xeb ntawm cov kav hlau tau hloov zuj zus los ntawm kev tiv thaiv ib txheej mus rau theem tshiab ntawm kev tiv thaiv lub neej tag nrho uas suav nrog "kev txhim kho cov khoom siv, kev ua kom zoo dua, thiab kev saib xyuas ntse."

Tam sim no, cov thev naus laus zis tiv thaiv xeb ntawm cov yeeb nkab hlau muaj ntau yam kev siv uas tsim los rau cov xwm txheej siv tshwj xeeb. Hauv cov kav dej faus, 3PE (peb txheej polyethylene txheej) tiv thaiv xeb yog qhov kev daws teeb meem zoo tshaj plaws rau cov kav dej roj thiab roj av ntev vim lawv tiv taus kev ntxhov siab ntawm av thiab cathodic disbonding. Lawv cov qauv sib xyaw, uas muaj cov hmoov epoxy hauv paus, cov nplaum nruab nrab, thiab cov txheej polyethylene sab nraud, muab kev tiv thaiv xeb thiab kev cuam tshuam. Rau cov kav dej kua qaub thiab alkaline hauv kev lag luam tshuaj lom neeg, cov txheej fluorocarbon thiab cov yas hauv ob sab hauv muab cov txiaj ntsig. Tus thawj coj siv cov tshuaj lom neeg tsis muaj zog ntawm fluororesins los tiv taus cov xov xwm corrosive heev, thaum tus tom kawg cais cov xov xwm thauj los ntawm cov yeeb nkab hlau nws tus kheej los ntawm kev sib xyaw cov phab ntsa sab hauv nrog cov ntaub ntawv xws li polyethylene thiab polytetrafluoroethylene. Ntxiv mus, kub-dip galvanizing yog siv dav hauv cov chaw muaj zog corrosive me ntsis xws li cov dej hauv nroog thiab cov dej ntws thiab cov qauv txhawb nqa hlau vim nws tus nqi qis thiab yooj yim teeb tsa. Kev ua haujlwm anodic ntawm zinc txheej muab kev tiv thaiv electrochemical ntev rau cov yeeb nkab hlau.

Kev txhim kho thev naus laus zis thiab kev tsim kho tshiab ua rau muaj kev txhim kho zoo ntawm cov yeeb nkab hlau tiv thaiv xeb. Cov txheej txheem pleev xim tes ib txwm muaj, vim muaj teeb meem xws li qhov tuab ntawm txheej tsis sib npaug thiab kev nplaum tsis zoo, maj mam hloov los ntawm cov kab ntau lawm. Cov thev naus laus zis tam sim no uas siv hluav taws xob thiab cov tshuab txau cua tuaj yeem ua tiav qhov tuab ntawm txheej hauv ± 5%. Hauv kev lag luam ntawm cov ntaub ntawv tiv thaiv xeb, cov txheej txheem epoxy uas tsis muaj kuab paug rau ib puag ncig thiab cov txheej txheem tiv thaiv xeb graphene hloov kho maj mam hloov cov txheej txheem uas muaj kuab paug, txo cov pa phem VOC thaum txhim kho cov txheej txheem tiv thaiv huab cua thiab kev hnav tsis kam. Tib lub sijhawm, cov txheej txheem saib xyuas ntse tau pib koom ua ke rau hauv cov txheej txheem tiv thaiv xeb. Cov yeeb nkab hlau hauv qee qhov haujlwm tseem ceeb tam sim no tau nruab nrog cov sensors tiv thaiv xeb. Cov sensors no sau cov teeb liab tam sim no thiab cov cim qhia kev puas tsuaj los ntawm phab ntsa sab nraud ntawm cov kav dej, ua rau muaj kev ceeb toom ntxov ntawm kev pheej hmoo ntawm kev ua tsis tiav ntawm xeb thiab kev kho kom raug.

Rau cov yeeb nkab hlau tiv thaiv xeb, kev pom zoo hauv kev lag luam yog tias "30% cov ntaub ntawv, 70% kev tsim kho." Ua ntej kev tsim kho, qhov chaw ntawm cov yeeb nkab hlau yuav tsum tau xuab zeb kom tshem tawm xeb thiab xyuas kom meej tias qhov chaw roughness ntawm Sa2.5 lossis siab dua. Kev kho mob no kuj tshem tawm cov khoom tsis huv xws li roj, nplai, thiab lwm yam khoom tsis huv, ua rau txoj hauv kev rau kev nplaum txheej. Thaum lub sijhawm tsim kho, qhov tuab ntawm txheej, qhov kub kho, thiab lub sijhawm yuav tsum tau tswj hwm kom tsis txhob muaj qhov tsis zoo xws li qhov pinholes thiab cov xau txheej. Tom qab ua tiav, qhov ua tau zoo ntawm kev tiv thaiv xeb yuav tsum tau txheeb xyuas los ntawm cov txheej txheem xws li kev sim hluav taws xob thiab kev sim nplaum. Tsuas yog los ntawm kev tsim kom muaj cov txheej txheem kaw, kaw-lub voj voog uas suav nrog "kev xaiv khoom siv - kev kho qhov chaw - kev tswj hwm kev tsim kho thiab kev tswj hwm - kev saib xyuas tom qab" tuaj yeem ua rau lub sijhawm ntev ntawm cov yeeb nkab hlau tiv thaiv xeb tau paub tiag tiag.

Nrog kev nce qib ntawm lub hom phiaj "ob chav carbon" thiab kev nce qib ntawm kev nyab xeeb hauv kev lag luam, cov yeeb nkab hlau tiv thaiv xeb thev naus laus zis yuav txuas ntxiv mus rau kev ntsuab dua, ua haujlwm tau zoo dua, thiab ntse dua. Yav tom ntej, cov ntaub ntawv tiv thaiv xeb tshiab uas sib xyaw cov khoom qis-carbon nrog kev tiv thaiv mus sij hawm ntev, nrog rau cov txheej txheem tiv thaiv xeb uas sib xyaw cov thev naus laus zis digital twin, yuav dhau los ua qhov tseem ceeb hauv kev tshawb fawb thiab kev txhim kho hauv kev lag luam. Cov no yuav muab lub zog tiv thaiv kev nyab xeeb rau ntau yam kav dej kev lag luam thiab pab txhawb rau kev ua haujlwm zoo ntawm cov khoom siv.
