Yuav Ua Li Cas Paub Qhov Tseeb Stainless Hlau Luj Tshib: Phau Ntawv Qhia Ceev
Stainless hlau luj tshib yog khoom plig rau lawv zoo heev corrosion kuj, tab sis qee tus neeg yuav nug txog qhov tseeb ntawm stainless hlau luj tshib lawv tau yuav vim pom muaj teeb meem nrog corrosion kuj. Niaj hnub no, peb yuav muab kev nkag siab txog yuav ua li cas koj thiaj paub qhov tseeb ntawm stainless hlau luj tshib.
Ib tug yam ntxwv meej ntawm stainless hlau luj tshib yog lawv qhov inherent tsis kam rau concentrated nitric acid thiab dilute nitric acid. Cov cuab yeej no tso cai rau lub luj tshib stainless hlau kom yooj yim sib txawv ntawm lwm yam hlau lossis alloys. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov pa roj carbon ntau zoo li 420 thiab 440 steel yuav muaj kev xeb me ntsis thaum lub sij hawm kuaj nitric acid. Cov hlau tsis-ferrous yuav raug corroded tam sim ntawd thaum raug cov concentrated nitric acid, thaum carbon steel luj tshib yuav undergo tseem ceeb corrosion nyob rau hauv ib tug dilute nitric acid ib puag ncig.
Ib qho kev sim yooj yim suav nrog kev txiav cov qauv, sib tsoo, thiab tom qab ntawd muab tso rau hauv sulfuric acid kom sib txawv ntawm 302 thiab 304 stainless hlau thiab 316 thiab 317 stainless hlau. Cov qauv ntawm 302 thiab 304 steel immersed nyob rau hauv 10% tov ntawm sulfuric acid, rhuab mus rau 71 degree, yuav corrode sai, ua npuas ntau thiab tig dub nyob rau hauv ob peb feeb. Hauv qhov sib piv, cov qauv ntawm 316 thiab 317 steel teb sai dua thiab feem ntau tsis hloov xim li ntawm 10-15 feeb. Yog li ntawd, qhov kev ntsuam xyuas sulfuric acid muab txoj hauv kev ceev kom sib txawv ntawm cov pa roj carbon monoxide thiab txhua hom stainless hlau.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov concentration ntawm sulfuric acid-tooj liab tov siv nyob rau hauv qhov kev ntsuam xyuas no yuav tsum nyob nruab nrab ntawm 5% thiab 10%. Ua ntej ua qhov chaw sim, ntxuav qhov chaw sim ntawm cov roj lossis cov khoom tsis huv, thiab txhuam ib ntu me nrog cov ntaub mos muag. Tom qab ntawd, siv lub dropper, ntxiv sulfuric acid-tooj liab tov rau thaj tsam npaj. Cov pa roj carbon steel los yog hlau yuav tsim ib txheej ntawm cov xim hlau tooj liab rau ntawm qhov chaw hauv vib nas this, thaum stainless hlau yuav tsis tso tooj liab los yog muaj xim tooj liab.
Hauv kev xaus, kev sim sulfuric acid yog ib txoj hauv kev yooj yim thiab zoo rau kev sib txawv ntawm cov pa roj carbon ntau thiab ntau hom stainless hlau. Los ntawm kev nkag siab txog txoj kev no, koj tuaj yeem ntsuas qhov tseeb ntawm lub luj tshib stainless hlau uas koj tau yuav.
Qhov kev paub no tuaj yeem muaj txiaj ntsig tshwj xeeb thaum ua kom ntseeg tau tias kev siv lub luj tshib stainless hlau tiag tiag hauv cov ntawv thov uas muaj kev tiv thaiv corrosion tseem ceeb, xws li hauv kev ua tshuaj lom neeg, khoom siv hauv tsev, lossis cov kav dej.
