Stainless hlau yog ib qho ruaj khov chromium nplua nuj oxide zaj duab xis tsim rau ntawm nws qhov chaw, uas yog nyias nyias, ruaj khov, thiab zoo.
Vim li cas stainless hlau hluav taws xob cua sov raj kuj xeb? Thaum cov xim av xeb (spots) tshwm rau ntawm qhov chaw ntawm stainless hlau hluav taws xob cua sov raj, tib neeg xav tsis thoob: lawv ntseeg tias "stainless hlau tsis xeb, thiab yog tias nws xeb, nws tsis yog stainless hlau. tube Hoobkas tau hloov stainless hlau nrog lwm cov ntaub ntawv. " Qhov tseeb, nws tsis yog li ntawd. Stainless hlau kuj tuaj yeem xeb nyob rau hauv qee yam mob. Stainless hlau muaj peev xwm tiv taus atmospheric oxidation, xws li xeb kuj, thiab kuj muaj peev xwm tiv thaiv corrosion hauv xov xwm uas muaj kua qaub, alkali, thiab ntsev, uas yog corrosion kuj. Tab sis qhov loj ntawm nws cov corrosion kuj txawv nrog cov tshuaj muaj pes tsawg leeg, kev sib nrig sib lub xeev, kev siv tej yam kev mob, thiab hom ntawm ib puag ncig nruab nrab ntawm cov hlau nws tus kheej. Piv txwv li, 304 steel kav muaj cov xeb zoo heev nyob rau hauv qhov chaw qhuav thiab huv si, tab sis thaum tsiv mus rau thaj chaw ntug dej hiav txwv, lawv yuav xeb sai sai hauv hiav txwv huab cua uas muaj cov ntsev ntau; Thiab 316 steel yeeb nkab ua tau zoo. Yog li ntawd, tsis yog txhua hom stainless hlau tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.
Stainless hlau yog ib qho ruaj khov chromium nplua nuj oxide zaj duab xis (cov yeeb yaj kiab tiv thaiv) tsim rau ntawm nws qhov chaw, uas yog nyias thiab ruaj khov, tiv thaiv cov pa oxygen atoms txuas ntxiv mus rau infiltrate thiab oxidize, yog li tau txais lub peev xwm los tiv thaiv corrosion. Ib zaug yog vim li cas, cov yeeb yaj kiab nyias no tau raug puas ntsoog tas li, cov pa oxygen atoms hauv huab cua lossis cov kua yuav tsis tu ncua infiltrate lossis hlau atoms hauv cov hlau yuav tsis tu ncua sib cais, tsim cov hlau oxide xoob, thiab cov hlau saum npoo yuav raug corroded tas li.
Txhawm rau kom ntseeg tau tias cov hlau saum npoo yog ci ntsa iab mus tas li thiab tsis muaj corroded, peb pom zoo kom qhov chaw ntawm stainless hlau hluav taws xob cua sov raj yuav tsum tau ntxuav tas li thiab txhuam kom tshem tawm cov ntawv txuas thiab tshem tawm cov khoom sab nraud uas ua rau xeb. Cov ntug hiav txwv dej yuav tsum siv 316 stainless hlau, uas tuaj yeem tiv taus dej hiav txwv corrosion.
