Tsib lub ntsiab lus los xav txog thaum xaiv stainless hlau
1. Tus qauv ntawm corrosion kuj yog artificially txiav txim siab. Nws yog ib qho tsim nyog yuav tsum paub txog nws, siv nws, thiab tsis raug khi los ntawm nws. Nws yog ib qho tsim nyog los txiav txim siab tus qauv tshwj xeeb ntawm kev tiv thaiv corrosion raws li kev siv tshwj xeeb.
Tam sim no, kev tiv thaiv corrosion ntawm stainless hlau feem ntau txais yuav 10- theem tus qauv. Cov qib twg yog xaiv raws li qhov yuav tsum tau muaj kev tiv thaiv corrosion yuav tsum xav txog cov yam ntxwv ntawm cov khoom siv thiab qhov chaw (thickness, loj). Qhov ntev ntawm kev pab cuam lub neej, cov khoom zoo (xws li impurities, xim, Feem ntau hais lus, rau cov cuab yeej, meters thiab cov khoom uas yuav tsum tau ib tug du daim iav nto los yog meej qhov ntev thaum siv, tus qauv 1-3 yuav xaiv tau; Cov khoom raug xaiv los ntawm qib 2 txog 5. Rau cov khoom siv uas tsis tas yuav tsum muaj siab rau kev saib xyuas yooj yim lossis kev ua haujlwm ntev, cov khoom tuaj yeem raug xaiv los ntawm qib 4 txog 7. Tsuas yog tshwj xeeb tshwj xeeb, cov hlau tsis muaj steel hlau uas nws txhua xyoo corrosion ntau tshaj 1 hli feem ntau. tsis xaiv. , Nws yuav tsum tau taw qhia tias tus qauv 10- qib tsis siv tau thaum muaj kev cuam tshuam hauv zos.
2. Corrosion kuj yog cov txheeb ze thiab muaj cai. Nws feem ntau hais tias stainless hlau yog xeb-resistant. Corrosion kuj hais txog cov txheeb ze rau xeb thiab tsis-corrosion kuj, nws yog hais txog tej yam kev mob (nruab nrab, concentration, kub, impurities, siab, txaus tus nqi, thiab lwm yam. rau ib lub sij hawm ntawm lub sij hawm). Txog rau tam sim no, tsis muaj cov hlau tsis muaj xeb nrog xeb thiab corrosion kuj nyob rau hauv ib puag ncig corrosive, yog li cov neeg siv khoom xaiv yuav tsum xaiv raws li cov kev siv tshwj xeeb, qib stainless hlau tom qab xaiv, cov neeg siv khoom yuav tsum siv kom raug raws li rau cov yam ntxwv ntawm kev xaiv stainless hlau, uas yog, tsim nyog xaiv cov ntaub ntawv thiab siv kom raug tuaj yeem ua tiav lub hom phiaj ntawm kev xeb-resistant lossis corrosion-resistant.
3. Kev xaiv ntawm stainless hlau yuav tsum xav txog tsis tsuas yog nws cov dav dav corrosion kuj, tab sis kuj nws lub zos corrosion kuj. Hauv qee qhov kev tshaj tawm aqueous thiab tshuaj lom neeg, tom kawg yuav tsum tau them nyiaj ntau dua. Qhov no yog vim hais tias cov neeg ua haujlwm xaiv feem ntau them nyiaj ntau dua rau cov hlau tsis muaj steel Qhov dav dav corrosion kuj ntawm stainless hlau, thiab nyob rau hauv cov kev mob ntawm kev siv, lawv rhiab heev rau lub zos corrosion, xws li kev nyuaj siab corrosion pitting corrosion, yog tsawg dua; lub zos corrosion ntawm stainless hlau feem ntau tshwm sim nyob rau hauv ib tug corrosive ib puag ncig nrog zoo general corrosion kuj. , Hauv zos corrosion feem ntau ua rau kev puas tsuaj tam sim ntawm cov khoom siv stainless hlau thiab cov khoom siv, uas yog qhov teeb meem ntau dua li kev xeb.
4. Thaum ua ntawv thov cov ntaub ntawv tiv thaiv corrosion ntawm stainless hlau nyob rau hauv ntau yam ntaub ntawv, nws yuav tsum tau muab sau tseg tias ntau ntawm cov ntaub ntawv tsuas yog cov kev ntsuam xyuas tshwm sim nyob rau hauv ib co thwmsim, thiab feem ntau muaj qhov sib txawv loj nrog qhov tseeb nruab nrab ib puag ncig. Corrosion cov ntaub ntawv, feem ntau, kev ntsuam xyuas corrosion ntawm qhov tseeb nruab nrab los yog daim coupon xeem nyob rau hauv tej yam kev mob yuav tsum tau nqa tawm nyob rau hauv lub chaw soj nstuam, thiab kev ntsuam xyuas ntawm lub simulation ntaus ntawv yuav tsum tau nqa tawm yog hais tias tsim nyog.
Hauv qee qhov kev siv, qhov xwm txheej no kuj yuav raug ntsib. Thaum cov khoom nruab nrab ua haujlwm lossis cov khoom lag luam tsim tawm, txawm tias muaj cov lej ntawm qee yam lossis qee yam hlau ions hauv stainless hlau, nws yuav cuam tshuam rau cov txheej txheem tshuaj thiab kev lag luam. Qhov zoo ntawm cov khoom (xws li gloss, xim, purity, thiab lwm yam). Qhov xwm txheej no feem ntau tshwm sim hauv kev lag luam xws li roj nuclear, tshuaj thiab pigments. Nyob rau lub sijhawm no, cov hlau tsis muaj steel tsis muaj qee lub ntsiab lus feem ntau xaiv los yog cov qib corrosion kuj ntawm cov hlau stainless uas tau xaiv tau raug kho kom tsim nyog, kom txo cov hlau ions kom muaj kev txwv.
5. Rau cov khoom siv hlau tsis muaj steel, yog tias cov khoom ua tsis tiav vim yog corrosion, qhov ua rau corrosion puas yuav tsum tau soj ntsuam, thiab kev ntsuas yuav tsum tau ua tom qab txheeb xyuas qhov ua rau, tsis txhob muab pov tseg.
