Kev sib tham ntawm cov txheej txheem xaiv ntawm kev tsim kho-resistant alloy cov ntaub ntawv hauv kev lag luam tshuaj
High corrosion-resistant alloy cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv cov txheej txheem siv tshuaj, thiab lawv cov kev ua tau zoo cuam tshuam rau lub neej ntawm cov cuab yeej thiab kev nyab xeeb ntau lawm. Kev xaiv ntawm cov ntaub ntawv zoo li no hauv kev lag luam tshuaj lom neeg xav tau kev txiav txim siab ntau yam thiab tsim kev tshuaj ntsuam xyuas kev tshawb fawb thiab tsim nyog.
1. Kev tsom xam ntawm cov yam ntxwv corrosion ntawm cov ntaub ntawv hauv kev siv tshuaj
Kev siv tshuaj lom neeg ib puag ncig yog feem ntau yog xeb, thiab muaj qhov sib txawv ntawm cov xov xwm corrosive hauv cov txheej txheem sib txuas. Hom kev sib cais muaj xws li cov khoom siv corrosion, pitting, kev nyuaj siab corrosion, kev nyuaj siab corrosion tawg thiab intergranular corrosion. Ua ntej xaiv cov ntaub ntawv, nws yog qhov tsim nyog yuav tsum tau tshuaj xyuas cov lus xws li nruab nrab muaj pes tsawg leeg, kub thiab cov roj ntsha hydrogen thiab acid-puag lwm yam. Kev kub siab thiab kev kub siab ib puag ncig yuav ua kom nrawm dua cov txheej txheem xeb, thiab saib xyuas kom ruaj khov rau cov khoom ruaj khov ntawm cov haujlwm hnyav.
2. Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm siab-resistant alloy cov ntaub ntawv
Corrosion tsis kam yog thawj qhov kev txiav txim siab rau kev xaiv, thiab cov ntaub ntawv yuav tsum tau txais los ntawm cov qauv tshuaj tiv thaiv ntawm cov qauv, suav nrog kev ntsuam xyuas ntawm cov qauv ntawm cov qauv, kev ntsuam xyuas hluav taws xob thiab cov kev sim ntawm chaw dai. Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, lub zog, cov yas thiab tawv ntawm cov khoom siv kub yuav tsum tau ntsuas kom ntseeg tau tias cov kev xav tau ntawm cov qauv txheej txheem. Kev ua kev ua si cuam tshuam nrog lub weldability, formability kho cov yam ntxwv ntawm cov khoom siv thiab ua tus nqi tsim khoom thiab ua tiav. Kev Ntsuam Xyuas Kev Lag Luam yuav tsum nkag siab txog qhov pib kev nqis peev thiab tus nqi ntawm tag nrho lub neej kom tsis txhob muaj cov txiaj ntsig tsawg ntawm kev siv.
3. Kev sib piv ntawm cov kev siv tshuaj ntawm feem ntau siv high-corrosion-resistant alloy cov ntaub ntawv
Austenitic stainless hlau xws li 316L series ua haujlwm zoo nyob rau hauv ib puag ncig corrosive me me, tab sis yog nkag siab rau chloride kev ntxhov siab corrosion. Duplex stainless hlau muaj ob qho tib si austenitic thiab ferritic qauv, muaj lub zog siab dua thiab ua rau chloride ntxhov siab corrosion. Nickel-based alloys xws li hastadoy series ua tau zoo nyob rau hauv cov kua qaub muaj zog thiab muaj txiaj ntsig ntau dua. Titanium thiab titanium alloys muaj zoo heev corrosion tsis kam mus rau chlorides thiab oxidizing media, tab sis lawv cov kev ua tau txo qis hauv cov acids txo qis. Zirconium alloys ua tau zoo nyob rau hauv ib tug dav PH ntau ntau thiab ntawm kev kub siab, tab sis yog kim thiab nyuaj rau kev ua.
4. Kev xaiv qhov kev txiav txim siab ua ib qho thiab cov hau kev
Cov txheej txheem xaiv yuav tsum ua raws li txoj kev ua haujlwm hauv txoj kev ua haujlwm, thawj zaug qhia meej cov kev pabcuam ntawm cov cuab yeej thiab theem ntawm tsis ua haujlwm. Kev ntsuam xyuas ua ntej ntawm cov khoom sib tw ntawm cov khoom sib tw raws cov yam ntxwv nruab nrab, thiab kev pov thawj ntawm lawv qhov kev kuaj mob thiab rooj plaub uas muaj kev sim. Xav txog kev txuam ntawm cov cuab yeej tsim lub neej thiab cov khoom siv uas xeb, thiab tsim nyog txiav txim siab rau kev xeb cov npoo. Rau cov cuab yeej tseem ceeb, nws pom zoo kom ua cov ntawv pov thawj me me los yog siv cov ntawv dai kev dai. Qhov kev txiav txim siab zaum kawg yuav tsum tau sib npaug thiab kev lag luam muaj peev xwm thiab cov khoom siv sib xyaw lossis cov khoom siv sib xyaw lossis cov qauv sib xyaw los txo cov nqi thaum tsim nyog.
V. Cov teeb meem thiab kev daws teeb meem hauv kev xaiv
Kev vam khom dhau-kev vam khom rau cov qib sib txawv yog qhov kev nkag siab tshwj xeeb, thiab cov neeg xa khoom yuav tsum muaj ntawv pov thawj ntxiv. Kev tsis quav ntsej txog cov kab txiav ntawm cov nruab nrab yuav ua rau tsis muaj kev npaj txhij txog kev ua tiav, thiab ib qho kev tsom xam ntawm cov txheej txheem kua muaj pes tsawg leeg. Thermal Kev ntxhov siab corrosion tshwm sim los ntawm kev kub siab tau hloov pauv, thiab cov khoom siv yoog raws li qhov cub kub uas yuav tsum tau ntsuas. Qhov yooj yim ntawm kev saib xyuas thiab cov khoom seem yuav tsum tau coj mus rau kev txiav txim siab kom tsis txhob xaiv tshwj xeeb ntau hom.
Kev xaiv scientific ntawm high-corrosion-resistant alsoy cov ntaub ntawv yuav tsum muaj kev lag luam tshuaj lom neeg thiab kev nplua nuj kev ua haujlwm tau tso tseg. Tsim kom muaj ib qho qauv xaiv ua tiav thiab kev tshuaj ntsuam xyuas yuav pab txhim kho kev ntseeg tau thiab muaj kev nyab xeeb thiab ruaj khov ntau lawm. Yav tom ntej, nws yog qhov tsim nyog ntxiv dag zog rau kev tsim kho cov khoom siv hluav taws xob, txhawb kev txhawb nqa cov ntaub ntawv tshuaj xyuas kev txiav txim siab rau kev xaiv.
