Kev tiv thaiv corrosion thiab xeb tiv thaiv ntawm marine steel daim hlau yog qhov tseem ceeb heev. Nov yog qee cov lus qhia ntxaws ntxiv:

 

I. Qhov tseem ceeb ntawm kev tiv thaiv corrosion thiab xeb tiv thaiv

 

Marine steel daim hlau tau raug rau ib puag ncig marine lub sijhawm ntev thiab ntsib teeb meem corrosion hnyav. Cov dej hiav txwv yog cov tshuaj electrolyte muaj zog uas muaj cov ntsev ntau, yaj oxygen, thiab ntau yam kab mob. Cov yam tseem ceeb no tuaj yeem ua kom nrawm nrawm ntawm cov hlau phaj. Corrosion tsis tsuas yog txo lub zog thiab kev pab cuam lub neej ntawm steel daim hlau tab sis kuj tseem tuaj yeem ua rau kev puas tsuaj rau lub nkoj cov qauv thiab ua rau muaj kev phom sij rau kev nyab xeeb ntawm lub nkoj. Yog li ntawd, kev siv cov tshuaj tiv thaiv corrosion thiab xeb tiv thaiv zoo yog qhov tseem ceeb rau kev ua haujlwm ntev ntawm cov nkoj, txo cov nqi tu, thiab ua kom muaj kev nyab xeeb kev nyab xeeb.

II. Txheej tiv thaiv

 

Hom thiab xaiv cov xim tiv thaiv corrosion

Epoxy xim: Nws muaj cov dej tsis zoo, tshuaj tiv thaiv corrosion, thiab adhesion, thiab yog haum rau cov cheeb tsam xws li lub nkoj hauv qab thiab hauv qab cov dej uas nyob rau lub sij hawm ntev kev sib cuag nrog dej hiav txwv.

Polyurethane xim: Nws muaj qhov tawv tawv, zoo hnav tsis kam, thiab siab gloss, thiab haum rau thaj chaw xws li lub nkoj superstructure thiab lawj.

Chlorinated roj hmab xim: Nws dries sai, muaj dej tsis kam, thiab yooj yim rau kev tsim kho. Nws feem ntau yog siv rau kev tiv thaiv ib ntus thiab tu cov nkoj.

Thaum xaiv cov xim tiv thaiv corrosion, yam xws li lub nkoj ua haujlwm ib puag ncig, kev ua haujlwm, thiab kev tu lub voj voog yuav tsum tau txiav txim siab xaiv cov xim tiv thaiv corrosion nrog kev ua tau zoo.

Txheej txheej kev tsim kho

Kev kho deg: Ua ntej pleev xim, lub phaj hlau yuav tsum tau muab ntxuav kom huv thiab kho kom tshem tawm cov impurities xws li roj stains, xeb, thiab oxide nplai kom ntseeg tau qhov adhesion ntawm txheej. Feem ntau siv txoj kev kho saum npoo av muaj xws li sandblasting, tua blasting, thiab pickling.

Primer txheej: Primer yog lub hauv paus ntawm txheej txheej txheej thiab feem ntau ua lub luag haujlwm ntawm kev tiv thaiv xeb thiab txhim kho adhesion. Kev xaiv primer yuav tsum tau txiav txim siab raws li cov khoom siv steel phaj thiab siv ib puag ncig. Feem ntau, epoxy primer los yog zinc-nplua nuj primer yog siv.

Intermediate coat painting: Lub tsho nruab nrab feem ntau ua lub luag haujlwm ntawm kev ua kom cov txheej tuab, txhim kho kev ua haujlwm tiv thaiv corrosion, thiab tiv thaiv. Kev xaiv ntawm lub tsho loj nruab nrab yuav tsum phim cov primer thiab topcoat. Feem ntau, epoxy micaceous hlau intermediate coat los yog polyurethane intermediate tsho yog siv.

Topcoat painting: Lub topcoat yog cov tsos txheej txheej txheej txheej thiab feem ntau ua lub luag haujlwm ntawm kev kho kom zoo nkauj thiab kev tiv thaiv. Kev xaiv ntawm topcoat yuav tsum tau txiav txim siab raws li lub nkoj qhov kev xav tau thiab kev siv ib puag ncig. Feem ntau, polyurethane topcoat los yog fluorocarbon topcoat yog siv.

Txheej tu thiab kho

Kev tshuaj xyuas tsis tu ncua: Kev tshuaj xyuas cov txheej txheem tsis tu ncua thiab kho tam sim cov teeb meem xws li kev puas tsuaj, hlwv, thiab tev. Kev soj ntsuam zaus yuav tsum tau txiav txim siab raws li lub nkoj siv ib puag ncig thiab kev saib xyuas, feem ntau ib xyoos ib zaug lossis ib zaug txhua ob xyoos.

Kev kho hauv zos: Rau cov txheej hauv zos puas, cov ntawv xuab zeb tuaj yeem siv los txhuam thiab ntxuav qhov chaw, thiab tom qab ntawd primer, nruab nrab lub tsho tiv no, thiab topcoat tuaj yeem rov qab siv dua. Thaum kho, kev saib xyuas yuav tsum tau them rau qhov sib tshooj thiab kev hloov pauv nrog cov txheej nyob ib puag ncig kom ntseeg tau tias muaj kev ncaj ncees ntawm txheej txheej.

Comprehensive recoating: Thaum cov txheej txheej muaj hnub nyoog hnyav, hnav, lossis muaj qhov chaw loj ntawm kev puas tsuaj, yuav tsum tau ua kom tiav cov txheej txheem. Ua ntej cov txheej txheem rov ua dua, cov phaj hlau yuav tsum tau muab ntxuav kom huv thiab kho, thiab tom qab ntawd rov ua dua yuav tsum tau ua raws li txheej txheem txheej txheem txheej txheem.
