Anti- cov kav dej xeb hlau ua lub luag haujlwm tseem ceeb hauv kev tsim kho engineering vim lawv cov khoom tshwj xeeb los tiv thaiv -corrosion zog thiab ntau yam kev siv. Cov hauv qab no yog kev tshuaj xyuas ntawm qhov zoo thiab qhov tsis zoo ntawm kev tiv thaiv -corrosion steel kav:
Qhov zoo
➢ Zoo corrosion kuj:
Los tiv thaiv - cov kav hlau steel tuaj yeem tiv taus ntau yam kev tawm tsam, xws li kua qaub, alkali, ntsev, dej, oxygen, thiab lwm yam, tiv thaiv cov kav hlau los ntawm corroding nyob rau hauv ib puag ncig hnyav, thiab ua kom ntev kev pab cuam lub neej ntawm steel kav.
Rau cov kav dej faus, cov txheej tiv thaiv -corrosion tuaj yeem cais cov dej noo, oxygen thiab lwm yam corrosive hauv av, tiv thaiv cov yeeb nkab steel los ntawm av corrosion.
➢ Zoo heev mechanical zog:
Los tiv thaiv- cov kav dej xeb hlau khaws cia lub zog siab thiab tawv ntawm cov yeeb nkab steel nws tus kheej, thiab tuaj yeem tiv taus sab nraud xws li siab dua, nruj thiab cuam tshuam.
Txawm hais tias nyob rau hauv ntev - cov kav xa mus rau qhov deb lossis hauv qee cov qauv tshwj xeeb engineering, los tiv thaiv - cov kav dej steel muaj peev xwm tswj tau cov khoom siv tshuab zoo kom ntseeg tau tias muaj kev nyab xeeb ntawm cov kav dej.
➢ Kev tsim kho yooj yim:
Anti- cov kav dej corrosion kuj yog lub teeb hauv qhov hnyav thiab yooj yim thauj thiab nruab.
Ntawm qhov chaw tsim kho, vuam, flange kev sib txuas thiab lwm txoj hauv kev tuaj yeem siv rau kev sib txuas. Cov txheej txheem tsim kho yog qhov yooj yim, uas tuaj yeem ua rau lub sijhawm tsim kho ntawm qhov project.
Rau qee qhov kev tiv thaiv -corrosion steel kav uas yuav tsum tau ntawm - qhov chaw ua, xws li txiav thiab qhib qhov, nws kuj tseem yooj yim rau kev khiav lag luam thiab yuav tsis ua rau muaj kev puas tsuaj ntau dhau rau cov txheej txheem tiv thaiv - corrosion.
➢ Smooth puab phab ntsa:
Tom qab kev kho tshwj xeeb, sab hauv phab ntsa ntawm cov yeeb nkab los tiv thaiv -corrosion steel yeeb nkab muaj qhov siab du thiab tsis yooj yim rau scale.
Qhov no tuaj yeem tsis tsuas yog txo cov dej ntws tawm ntawm cov kav dej thiab txo cov kev siv hluav taws xob, tab sis kuj tseem zam cov kav dej thaiv thiab hauv zos corrosion los ntawm kev scaling.
➢ Tus nqi kho mob qis:
Vim tias cov tshuaj tiv thaiv -corrosion steel yeeb nkab muaj kev tiv thaiv corrosion zoo thiab cov khoom siv kho tshuab, nyob rau hauv kev siv ib txwm siv, nws tsis tas yuav tsum tau saib xyuas thiab hloov ntau zaus, uas txo cov nqi tu ntawm cov kav dej.
Txawm hais tias yuav tsum muaj kev saib xyuas, nws yooj yim heev, thiab tsuas yog kho hauv zos lossis hloov cov txheej txheem tiv thaiv -corrosion.
➢ Kev tiv thaiv ib puag ncig thiab txuag hluav taws xob:
Cov yeeb nkab los tiv thaiv -corrosion steel yeeb nkab muaj kev sib khi zoo, uas tuaj yeem txo cov pa tawm ntawm qhov nruab nrab thaum thauj thiab txo cov pa phem rau ib puag ncig.
Nyob rau tib lub sijhawm, cov yam ntxwv ntawm cov phab ntsa du thiab tsis muaj zog kuj tseem pab txuag lub zog, uas ua tau raws li cov kev xav tau ntawm lub neej niaj hnub rau kev tiv thaiv ib puag ncig thiab txuag hluav taws xob.

◆ Cov nyhuv thaiv: Cov txheej tiv thaiv - corrosion tuaj yeem thaiv qhov nruab nrab corrosive sab nraud los tiv thaiv cov yeeb nkab steel los tiv thaiv corrosion. Piv txwv li, polyethylene anti- txheej txheej corrosion tuaj yeem tiv thaiv cov dej noo, oxygen thiab corrosive hauv cov av los ntawm kev nkag mus rau saum npoo ntawm cov yeeb nkab steel; cov epoxy thee tar anti- txheej txheej txheej txheej txheej txheej txheej txheej xim xim kom cais cov dej, oxygen thiab lwm yam corrosive thiab tiv thaiv cov yeeb nkab steel los ntawm corrosion.
◆ Corrosion inhibition: Qee cov khoom siv los tiv thaiv -corrosion muaj cov tshuaj tiv thaiv corrosion, uas tuaj yeem ua rau qeeb ntawm corrosion ntawm cov kav hlau. Corrosion inhibitors tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov yeeb nkab steel los tiv thaiv cov tshuaj tiv thaiv corrosion.
◆ Kev tiv thaiv hluav taws xob: Rau qee qhov kev tiv thaiv cov yeeb nkab steel siv cathodic tiv thaiv thev naus laus zis, cathode tam sim no tau siv rau saum npoo ntawm cov yeeb nkab steel los ua kom cov yeeb nkab steel yog cathode, yog li inhibiting qhov tshwm sim ntawm corrosion.

Anti- cov kav dej xeb hlau ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw vim lawv lub zog siab thiab zoo tiv thaiv- kev ua haujlwm corrosion, suav nrog tab sis tsis txwv rau:
◆ Kev lag luam tshuaj lom neeg: Cov kav dej uas thauj ntau yam corrosive media yuav tsum siv cov kav dej los tiv thaiv -corrosion steel los xyuas kom muaj kev nyab xeeb ntawm cov kav dej.
◆ Kev tsim kho hauv nroog: Raws li ib qho ntawm cov ntaub ntawv tseem ceeb rau kev siv dej hauv nroog thiab cov kav dej, cov kav dej phwj tuaj, kev txhawb nqa choj, thiab lwm yam.
◆ Marine engineering: Cov dej hiav txwv muaj zog heev rau cov hlau zoo tib yam, thiab tiv thaiv - cov kav dej xeb tuaj yeem tiv taus cov dej hiav txwv zoo thiab ua rau lub neej ntev ntawm cov kav dej.
◆ Kev lag luam kev tiv thaiv ib puag ncig: Ntau yam khoom siv kho dej khib nyiab, cov cuab yeej siv roj pov tseg, thiab lwm yam. yuav tsum tau siv cov kav dej los tiv thaiv -corrosion steel.
◆ Kev lag luam metallurgical: Ntau qhov siab - kub thiab siab - cov kua dej siab yuav tsum tau thauj los ntawm cov kav dej, thiab cov kav hlau zoo tib yam yog qhov ua rau deformation thiab corrosion nyob rau hauv qhov kub thiab txias. Yog li ntawd, siab -kub, siab-resistant, thiab corrosion-tiv thaiv-corrosion steel kav yuav tsum tau.
◆ Fais fab kev lag luam: Siv los tiv thaiv- cov kav dej xeb hlau los tsim cov kab hluav taws xob kev txhawb nqa xws li cov yees los txhim kho lawv lub neej thiab kev ruaj ntseg.
◆ Kev Thauj Mus Los: Siv rau cov kav dej hauv qhov tunnels, kev txhawb nqa choj, thiab lwm yam.
