Corrosion puas tsuaj yog thawj qhov ua rau kev tshem tawm ntxov ntawm cov faus carbon steel pipelines. Raws li kev paub tab los tiv thaiv-corrosion technical route, polyurethane txheej tau tsim pom tseeb qhov chaw sib txawv piv nrog FBE fusion bonded epoxy txheej, 3LPE polyethylene txheej thiab kua epoxy txheej. Tej Tshuag ntawm polyurethane los tiv thaiv-corrosion steel kav khaws cia hauv peb lub Hoobkas qhia kev ruaj khov tsim muaj peev xwm. Txhua cov yeeb nkab steel mus los ntawm ntau qhov kev tshuaj xyuas los ntawm cov yeeb nkab nyoos tuaj mus rau cov khoom tiav tiav, txhua txoj kev txiav txim siab ncaj qha los tiv thaiv - kev ua haujlwm corrosion tom qab cov kav dej tau faus rau hauv av
Cov txheej txheej txheej ntawm polyurethane los tiv thaiv- txheej txheej yog txiav txim siab nws txoj kev tiv thaiv zoo. Tag nrho cov txheej txheem txheej txheej yog ua tiav nyob rau hauv cov txheej txheem tsim cov kab ntau lawm, zam qhov tsis ruaj tsis khov los ntawm kev tsim kho sab nraum zoov. Ua ntej txheej txheej txheej, cov pa roj carbon steel hauv paus yeeb nkab tau dhau qhov kev kho mob ntawm qhov chaw blasting kom tshem tawm cov xeb, oxide nplai thiab cov kab mob ntawm qhov chaw, mus txog qhov tsim nyog roughness los xyuas kom meej kev sib raug zoo ntawm substrate thiab txheej txheej. Cov txheej txheem tiv thaiv polyurethane feem ntau yog tsim los ntawm kev sib koom ua ke primer txheej thiab compact polyurethane topcoat txheej; Tom qab cua sov thiab txau, cov khoom siv polyurethane tau kho cov tshuaj tua kab mob los tsim cov yeeb yaj kiab txuas ntxiv, seamless, elastic tiv thaiv zaj duab xis ze rau ntawm cov hlau. Raws li qhov project geological tej yam kev mob, peb muaj peev xwm muab ib tug - txheej polyurethane txheej los yog reinforced tuab - zaj duab xis polyurethane txheej tov. Thickened txheej txheej yog tsim tshwj xeeb rau cov cheeb tsam uas muaj av salinity siab, nquag geological hloov chaw thiab muaj zog tshuaj corrosion.
Elasticity thiab cuam tshuam tsis kam yog cov yam ntxwv tshwj xeeb tshaj plaws ntawm polyurethane los tiv thaiv -corrosion txheej. Cov kav dej faus yuav ntsib cov av tsis tu ncua, kev sib haum xeeb hauv paus thiab cuam tshuam sab nraud thaum lub sijhawm ua haujlwm ntev -. Rigid anti-corrosion coatings xws li qee cov khoom epoxy yog nquag tawg nyob rau hauv me ntsis deformation, ib zaug tawg tshwm, corrosive nruab nrab yuav nkag mus thiab ua rau lub zos steel pitting corrosion. Sib txawv, kho polyurethane txheej khaws cia nruab nrab elasticity. Thaum lub raj xa dej dais me ntsis dabtsi yog khoov, extrusion los yog kev sib tsoo, lub txheej tuaj yeem deform synchronously yam tsis muaj cracking lossis tev tawm. Dhau li ntawm kev ua haujlwm zoo, cov khoom siv polyurethane muaj cov dej tsis zoo. Lub compact molecular qauv zoo heev txo cov dej nqus tus nqi, zoo thaiv cov dej hauv av, chloride ions thiab sulfide los ntawm kev tiv tauj steel matrix. Nws kuj tseem muaj kev tiv thaiv ruaj khov tiv thaiv acidic thiab alkaline av ib puag ncig hauv ntau thaj tsam
Los ntawm tag nrho - kev ntsuas tus nqi ntawm lub neej, polyurethane coated steel yeeb nkab coj tau cov txiaj ntsig kev lag luam zoo heev rau cov kav dej. Txawm hais tias lub Hoobkas prefabricated los tiv thaiv- kev ua haujlwm corrosion coj tus nqi ua haujlwm nruab nrab, kev tiv thaiv kev ruaj ntseg tuaj yeem txo qis txij nkawm ntau zaus. Ntau qhov dej num xaiv qis- tus nqi qis dua los tiv thaiv- cov kav dej xeb kom txuag tau thawj zaug peev, tab sis txheej txheej tsis ua haujlwm tshwm sim hauv lub sijhawm luv luv. Pipeline excavation, ib nrab cov yeeb nkab hloov thiab kaw ntau lawm yuav ua rau staggering ntxiv kev siv nyiaj. Polyurethane los tiv thaiv- txheej txheej corrosion tuaj yeem tswj kev tiv thaiv tsis zoo rau ntau xyoo raws li cov txheej txheem faus, ua kom ncua sijhawm txij nkawm thiab txo qis ntev - lub sijhawm ua haujlwm peev rau cov neeg ua haujlwm kav dej
Tag nrho cov kav dej tiav lawm tso tawm hauv tsev khaws khoom tau txais cov qauv tsim cov yeeb nkab kawg tiv thaiv. Cov cim ruaj khov uas muaj cov lus qhia tshwj xeeb, tiv thaiv- hom kev xeb thiab cov ntaub ntawv tsim khoom tau luam tawm ntawm cov yeeb nkab kawg lub hau, tiv thaiv cov khoom tsis sib haum xeeb thaum thauj dej hiav txwv, chaw nres nkoj tshem tawm thiab ntawm - qhov chaw faib khoom. Peb txhawb kev kho cov pob khoom thiab cov phiaj xwm thauj khoom tsim nyog rau kev thauj mus los ntev - deb. Raws li kev tsim cov duab kos los ntawm cov neeg siv khoom txawv teb chaws, sab nraud txoj kab uas hla, phab ntsa thickness thiab txheej thickness tsis tuaj yeem hloov kho kom haum rau cov qauv hauv zos engineering hauv ntau lub teb chaws. Rau cov neeg ua haujlwm engineering uas ua qhov tseem ceeb hauv kev tsim kho kev ruaj ntseg, ntev -lub sij hawm tiv thaiv- corrosion effect thiab ua tiav kev pabcuam kev pabcuam, polyurethane anti-corrosion coated steel yeeb nkab yog ib qho kev txhim khu kev qha thiab tus nqi{10}}cov kav dej zoo
