Floating hlau hmoov los yog embedded hlau yuav corrode stainless hlau

Ntawm txhua qhov chaw, cov hlau tsis muaj xeb thiab corrodes stainless hlau. Yog li ntawd, nws yuav tsum tau muab tshem tawm. Float hmoov feem ntau yuav raug tshem tawm nrog rau cov hmoov av. Qee qhov muaj zog adhesion thiab yuav tsum tau kho raws li cov hlau embedded. Ntxiv nrog rau cov plua plav, muaj ntau qhov chaw ntawm cov hlau saum npoo av, suav nrog kev ntxuav nrog cov pa roj carbon zoo tib yam hlau txhuam thiab tua blasting nrog xuab zeb, iav hlaws lossis lwm yam abrasives yav dhau los siv rau cov pa roj carbon steel, cov hlau tsis tshua muaj hlau lossis cov hlau cam khwb cia, lossis polishing. aforementioned uas tsis yog-stainless steel khoom nyob ze stainless hlau qhov chaw thiab khoom siv. Hlau ntawm cov hlua hlau, cov khoom sib kis thiab cov chaw ua haujlwm tuaj yeem yooj yim ua rau hauv qhov chaw los yog stains yog tias cov hlau tsis muaj kev tiv thaiv thaum tshem tawm lossis nqa. Kev txiav txim siab thiab kev tshuaj xyuas tom qab tsim khoom tuaj yeem tiv thaiv thiab kuaj pom muaj cov hlau dawb, ASTM tus qauv A380[3] qhia txog cov txheej txheem xeb rau kev tshuaj xyuas cov hlau lossis hlau ntawm cov hlau tsis huv. Qhov kev sim no yuav tsum tau siv thaum nws xav tau tias yuav tsum tsis muaj hlau tam sim no. Yog tias cov txiaj ntsig tau txaus siab, ntxuav lub ntsej muag nrog cov dej ntshiab huv lossis nitric acid kom txog thaum lub teeb xiav tsaus tag. Raws li tau teev tseg hauv tus qauv A380[3], yog tias cov tshuaj tiv thaiv xeb tsis tuaj yeem raug tshem tawm tag nrho, nws tsis pom zoo kom siv txoj kev sim no ntawm cov txheej txheem ntawm cov khoom siv, piv txwv li qhov chaw sib cuag ncaj qha siv los tsim cov khoom siv tib neeg. Ib txoj kev sim yooj yim yog kom raug dej rau 12 mus rau 24 teev los xyuas seb puas muaj cov kab xeb. Cov kev sim no tsis tshua muaj siab thiab siv sijhawm ntev. Cov no yog cov kev kuaj xyuas, tsis yog txoj kev ntxuav. Yog tias pom muaj hlau nyob, nws yuav tsum tau ntxuav nrog cov tshuaj thiab electrochemical txoj kev piav qhia hauv qab no.
