Kev tiv thaiv corrosion txheej feem ntau muab faib ua cov tshuaj pleev xim rau cov txheej txheem thiab cov txheej txheem tiv thaiv tsis xeb, uas yog qhov tseem ceeb hauv kev tiv thaiv. Piv nrog tshuaj pleev ib ce tiv thaiv tsis tau zoo, tshuaj pleev xim tiv thaiv ib puag ncig yog ib hom tshuaj tiv thaiv kev txhim kho uas tuaj yeem siv hauv kev tiv thaiv kev puas tsuaj. Nws muaj lub sijhawm tiv thaiv ntev dua li tsoos tsho ib puag ncig tiv thaiv. Nws muaj anti-xeb nyhuv ntawm cov hlau nyob rau hauv ib txwm mob thiab tiv thaiv lub neej kev pab ntawm cov hlau tsis huv. Hnyav plaub hau los tiv thaiv corrosion txheej yog ib hom anti-corrosion txheej haum rau qhov chaw hnyav heev. Nws lub sijhawm tiv thaiv ntev tshaj li cov txheej txheem los tiv thaiv corrosion.
1. Nws tuaj yeem siv nyob rau hauv cov xwm txheej hnyav thiab muaj lub neej tiv thaiv corrosion ntev ntev. Cov txheej txheem hnyav tiv thaiv kev lag luam yog siv rau hauv cov tshuaj huab cua thiab qhov chaw ib puag ncig marine. Feem ntau, lawv tuaj yeem siv rau ntau tshaj 10 xyoo, txawm nyob hauv cov kua qaub, alkali, ntsev thiab cov kuab tshuaj. Nws tuaj yeem siv ntau dua 5 xyoos ntawm qhov ntsuas kub.

2. Tuab zaj duab xis yog daim paib tseem ceeb ntawm qhov hnyav tiv thaiv xeb. Feem ntau, cov yeeb yaj kiab qhuav ntawm cov txheej txheem los tiv thaiv corrosion yog li 100μm lossis 150μm, thaum lub sij hawm qhuav zaj duab xis tuab ntawm hnyav los tiv thaiv corrosion txheej yog 200μm lossis ntau dua 300μm, thiab cov zaj duab xis qhuav yog 500μm ~ 1000μm lossis ntau dua.
3. Cov nplaum muaj zog: Cov txheej muaj qhov nplaum muaj zog rau cov substrate. Cov lus muaj pes tsawg leeg muaj hydroxyl (-OH), thiab cov hlau txheej tau muab cov ions zoo. Tus sawv cev txuas ntawv siv tau los ua cov ntawv cog lus sib txuas hauv cov txheej txheej, thiab txawm tias ua tiav cov txiaj ntsig cov nqi sib xyaw Raws li kev saib xyuas ntawm qhov chaw tsim qauv, cov hlau oxide nanomaterials thiab lub ntiaj teb tsis tshua zoo oxide ultrafine hmoov muaj nyob rau hauv cov qauv txheej txheem pab kom cov txheej tsim kom tuab tuab txoj kev hloov txheej txheej, kom nws cov qauv zoo ntawm cov thermodynamic phim rau hauv matrix.
4. Yooj yim ua kom yooj yim: Kev tsim kho yog lub teeb thiab yooj yim, thiab qhov kev kho tus kheej ntawm inorganic txheej ntawm chav tsev kub yog ua tiav. Thaum qhov kub yog 20 ℃ thiab cov txheeb ze cov av noo yog tsawg dua 85%, lub npoo av qhuav rau 15 feeb thiab lub zog qhuav rau 2 teev, uas tuaj yeem ua kom muaj kev tsim kho zoo thiab ua tiav cov ntsev zoo txau tiv taus kom laus. Cov txheej yog kho qhov nws tus kheej, thiab qee qhov khawb tau tsim los ntawm sab nraud quab yuam tseem tuaj yeem raug hlub. Cov xim tsis puas vim los ntawm kev txiav thiab txuas. Coated vuam tsis cuam tshuam rau qhov tsis zoo vuam.
5. Txoj kev qoj ib ce yooj yim:
Inorganic polymer anticorrosive txheej tuaj yeem siv ib leeg los yog ua cov tshuaj anticorrosive tsawg txheej txheej nrog xim xim inorganic. Thaum ib-txheej inorganic polymer anticorrosive txheej yog siv los ua tus primer, nws tuaj yeem siv nrog epoxy, acrylic, thiab polyurethane.
①Txhais zoo nkauj los tiv thaiv kev ua tau zoo: kev ua kom zoo adhesion, zoo heev tiv thaiv corrosion thiab lub neej ntev.
②Txhais kev tsim kho ua tau zoo: nws tuaj yeem kho tau sai sai ntawm chav tsev kub ib yam li cov qub los tiv thaiv corrosion txheej, thiab kev tsim kho yog yooj yim, thiab nws tuaj yeem ua haujlwm los ntawm cov tsis muaj peev txheej (qhov laj thawj yog vim li cas cov roj chlorinated hnyav ua haujlwm tiv thaiv xeb tuaj yeem tau ob peb daim ntawv thov tseem ceeb vim tias qhov kev ceeb toom no).
③ Zoo tshaj plaws ntawm ib puag ncig kev ua tau zoo: cov ntsiab lus zoo ntawm cov tshuaj tiv thaiv ib puag ncig tiv thaiv anticorrosive tsuas yog tuaj yeem ncav cuag 50 ~ 60%, thaum cov ntsiab lus ntawm cov khoom hnyav ntawm cov tshuaj tiv thaiv hnyav tau tuaj yeem ncav cuag 70% ~ 80%, lossis tseem 90% ~ 99%. Qhov hnyav nce yog ze li ntawm Ib nrab, qhia kev ua haujlwm zoo ib puag ncig.
Phthalocyanine ntsuab, phthalocyanine xiav, roj-soluble liab, xim txiv kab ntxwv mus tas li
