Hauv kev lag luam niaj hnub thiab cov dej ntws hauv nroog, nqus twj yog cov khoom siv dej phwj tuaj ua ke xws li cov dej phwj tuaj, kev siv dej ua kom dej paug, thiab tso tawm hauv nroog. Vim muaj cov tshuaj loj ntawm cov tshuaj corrosive xws li cov kua qaub, thiab cov kuab tshuaj hauv qab, ua rau cov khoom siv tsis zoo thiab txo cov kev ua haujlwm luv luv. Stainless hlau dej twj tso kua mis tau dhau los ua kev xaiv zoo tshaj plaws rau kev daws qhov kev sib tw no vim lawv tau ua tiav corrosion.
1, cov yam ntxwv
Stainless hlau yog ib qho kev siv hlau alloy suav nrog cov khoom xws li hlau, chromium, thiab lwm yam ntawm cov hlau corrosion. Thaum cov yeeb yaj kiab chomium oxide yog tsim nyob rau saum npoo ntawm stainless hlau, yog li ua tiav cov nyhuv ntawm corrosion tsis kam. Tsis tas li, ntxiv rau ntawm cov menyuam yaus xws li npib tsib thiab molybdenum txuas ntxiv txhim kho cov corrosion tsis kam thiab kub ua rau ntawm stainless hlau.
2, corrosion resistance mechanism
1. Passivation zaj duab xis tiv thaiv: Cov yeeb yaj kiab chromium oxide zaj duab xis (Passivation zaj duab xis muaj cov tshuaj ruaj khov thiab tuaj yeem tiv thaiv cov yaig ntawm cov tub ceev xwm. Thaum cov zaj duab xis passive puas, cov chromium lub caij hauv cov hlau stainless yuav cia li kho cov yeeb yaj kiab nyias nyias, yog li tswj hwm nws corrosion tsis kam.
2. Piv txwv li, Molybdenum tuaj yeem txhim kho cov corrosion tsis kam ntawm stainless hlau hauv corroside uas muaj peev xwm txhim kho cov hlau corroside uas tsis kam ntawm cov hlau tsis muaj pa acidic.
3, corrosion kuj kuaj
Txhawm rau ntsuas qhov corrosion tsis kam ntawmDej Twj Tso Kua Dej, cov lej ntawm cov kev sim thiab cov kev sim feem ntau tau ua. Cov hauv qab no yog ntau txoj kev coj ua rau kev sim corrosion resistance:
1. Ntsev tshuaj tsuag: Tso cov twj tso kua dej hauv cov ntsev tsuag dej hauv ib puag ncig thiab saib nws txoj kev xeb dhau lub sijhawm. Txoj kev no yog siv los soj ntsuam cov xeb ntawd tsis kam ntawm cov hlau stainless hauv ntsev muaj ib puag ncig.
2. Acid alkali kuaj: Soak lub taub dej hauv cov kua qaub thiab alkali daws teeb meem thiab saib nws tus cwj pwm corrosion dhau ib lub sijhawm. Txoj kev no yog siv los ntsuas cov xeb pheej tsis ntawm cov hlau tsis xeb hauv cov acidic thiab alkaline ib puag ncig.
3. Electrochemical Testing: Los ntawm kev siv cov txheej txheem hluav taws xob, cov kab xeb tam sim no thiab muaj peev xwm ntawm cov twj tso kua dej yog ntsuas kom ntsuas nws txoj kev ua kom corrosion tsis zoo. Cov qauv no muaj qhov siab dua thiab qhov tseeb.
4, Daim Ntawv Thov Kev Sau Npe
1. Dej phwj tuaj tua: Thaum lub lim dej phwj tuaj kho, cov dej phwj vov muaj cov tshuaj loj ntawm cov khoom muaj xeb. Stainless hlau dej twj tso kua mis ua tau zoo tiv thaiv kev xeb ntawm cov tshuaj thiab ua kom qhov ntev}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} l;
2. Muaj cov tshuaj tso dej kom dej paug: hauv cov tshuaj, cov khoom siv tshuaj, cov khoom siv corrosive hauv dej, uas tuaj yeem tiv thaiv cov khoom siv corrosion thiab ncua kev pabcuam lub neej.
3. Kev Ua Si Hauv Nroog: Hauv nroog kom dej ntws, dej nag muaj cov tshuaj uas muaj dej nag thiab ua kom muaj cov haujlwm ua haujlwm ib txwm muaj.
5, txij nkawm thiab upkeep
1. Kev tshuaj xyuas: tsis tu ncua xyuas qhov chaw nres tsheb, kuaj pom kom sai thiab kho cov ntsiab lus saum npoo av thiab tiv thaiv corrosion, thiab tiv thaiv corrosion los ntawm kis mus.
2. Kev tu thiab kho cov taub dej kom tshem tawm cov khoom lag luam thiab cov plua av txuas nrog saum npoo av, thiab khaws cov ntaub ntawv huv thiab qhuav.
3. Lubrication kev saib xyuas: Nrov ntub cov chaw txav ntawm cov taub dej kom ntseeg tau ntawm cov khoom siv thiab txo cov kev hnav thiab corrosion.
Hlau Hlau Dej Twj Tso Kua Mis Twjtau siv dav hauv cov liaj teb xws li cov dej phwj tuaj, kev siv dej ua kom dej paug, thiab cov moos tawm mus vim lawv txoj kev ua haujlwm corrosion. Los ntawm cov khoom tsim tsim nyog xaiv thiab kev saib xyuas kev tshawb fawb ntawm cov khoom siv hluav taws xob stainless nqus tuaj yeem txuas ntxiv, thiab ua haujlwm tau zoo dua. Kuv vam tias tsab xov xwm no tuaj yeem muab cov lus qhia muaj txiaj ntsig thiab kev pab rau cov neeg siv, thiab txhawb nqa cov twj tso kua dej thoob plaws hauv ntau thaj teb.
