Rau stainless hlau, nws feem ntau suav hais tias yog cov hlau tsis yooj yim rau xeb, tab sis qhov tseeb stainless hlau kuj tuaj yeem xeb.Cov xeb thiab corrosion kuj ntawm stainless hlau yog vim yog tsim los ntawm chromium-nplua nuj oxide zaj duab xis (passivation zaj duab xis) ntawm nws nto.Qhov no xeb kuj thiab corrosion kuj yog txheeb ze.
Cov kev ntsuam xyuas qhia tau hais tias qhov corrosion kuj ntawm cov hlau hauv cov xov xwm tsis muaj zog xws li huab cua thiab dej thiab hauv oxidizing media xws li nitric acid nce ntxiv nrog rau cov ntsiab lus chromium hauv cov hlau.Thaum cov ntsiab lus chromium nce mus txog ib feem pua, qhov corrosion kuj ntawm steel hloov sai sai., uas yog, los ntawm yooj yim rau xeb kom tsis yooj yim rau xeb, thiab los ntawm corrosion-resistant mus corrosion-resistant.
Txhawm rau kuaj seb lub valve stainless hlau puas tuaj yeem xeb, tib lub valve tuaj yeem muab tso rau hauv qhov chaw sib txawv rau kev txheeb xyuas thiab sib piv.
Nyob rau hauv ib txwm muaj xwm txheej, yog hais tias lub stainless hlau valve yog muab tso rau hauv ib tug kuj qhuav ib puag ncig, tom qab ib tug ntev lub sij hawm, lub valve tsis yog nyob rau hauv zoo xwb, tab sis kuj tsis muaj xeb.
Thiab yog tias lub valve muab tso rau hauv dej hiav txwv nrog ntsev ntau, nws yuav xeb tsis pub dhau ob peb hnub.Yog li ntawd, qhov kev tiv thaiv corrosion thiab stainless hlau khoom ntawm stainless hlau li qub kuj yuav tsum tau ntsuas raws li ib puag ncig.
"Los ntawm cov yam ntxwv ntawm stainless hlau valve nws tus kheej, yog vim li cas vim li cas nws yog stainless yog hais tias muaj ib tug txheej ntawm chromium-nplua nuj oxide zaj duab xis nyob rau hauv nws nto los tiv thaiv lub sab nraud oxygen atoms thiab lwm yam hais los ntawm kev puas tsuaj rau cov khoom, yog li ntawd. lub valve muaj cov yam ntxwv ntawm stainless hlau. "Cov kws tshaj lij Txawm li cas los xij, thaum lub membrane puas los ntawm tej yam xws li ib puag ncig, nws yuav xeb nrog kev nkag ntawm oxygen atoms thiab dissociate los ntawm hlau ions.
Muaj ntau qhov laj thawj rau kev xeb ntawm stainless hlau li qub, xws li cov tshuaj tiv thaiv electrochemical ntawm daim nyias nyias thiab lwm yam hlau ntsiab lus los yog plua plav, thiab kev siv cov huab cua ntub los ua ib qho nruab nrab los tsim lub voj voog micro-roj teeb, uas ua rau cov hlau tsis huv. nto xeb.
Lwm qhov piv txwv yog tias stainless hlau nto zaj duab xis ncaj qha mus rau hauv kev sib cuag nrog cov kua corrosive xws li muaj zog acids thiab alkalis, ua rau corrosion thiab lwm yam.Yog li ntawd, nyob rau hauv kev txiav txim rau lub stainless hlau valve kom tsis txhob xyuam xim, nws yog ib qho tsim nyog los them rau kev tu cov khoom hauv txhua hnub thiab khaws cov npoo ntawm lub pob hluav taws xob txhua hnub.
Yog li, yog tias lub valve stainless hlau yog xeb, tus neeg siv yuav daws qhov teeb meem no li cas?
Ua ntej, nws yog ib qho tsim nyog yuav tsum tau ntxuav thiab txhuam qhov saum npoo ntawm stainless hlau valve nquag kom tshem tawm cov ntawv txuas thiab tshem tawm cov khoom sab nraud uas ua rau xeb.
Qhov thib ob, 316 stainless hlau yuav tsum tau siv nyob rau hauv seaside cheeb tsam, vim hais tias 316 cov khoom yuav tiv taus corrosion ntawm seawater.
Thib peb, cov tshuaj muaj pes tsawg leeg ntawm qee cov kav hlau stainless ntawm lub khw tsis ua raws li cov qauv hauv lub tebchaws thiab tsis ua raws li cov khoom siv ntawm 304, yog li nws tseem yuav ua rau xeb.Hauv qhov no, cov kws tshaj lij tau hais tias thaum cov neeg siv xaiv stainless hlau li qub, lawv yuav tsum ua tib zoo xaiv cov khoom los ntawm cov tuam txhab muaj npe nrov.Bund stainless hlau valve, cov khoom zoo heev, zoo zoo, yog koj qhov kev xaiv zoo ~
Tsuas muaj ob peb kis ntawm stainless hlau li qub rusting.Feem ntau, kev ruaj ntseg li qub uas ua los ntawm cov hlau tsis muaj steel muaj kev nyab xeeb thiab tsis sib xws los ntawm lwm cov ntaub ntawv.Yog li ntawd, lub valve ntawm cov khoom siv no muaj ntau heev nyob rau hauv ib puag ncig ntawm qee qhov kev tshaj tawm txaus ntshai, thiab nws kuj yog tus yuam sij los xyuas kom meej nws cov kev ua tau zoo.
Tsis tas li ntawd, stainless hlau li qub feem ntau nyob rau hauv kev sib cuag nrog ib co kua xov xwm, thiab ib puag ncig yog feem ntau ntub dej, thiab cov anti-xeb kom zoo dua ntawm no hom valve tau dhau los ua ib qho txiaj ntsig zoo, thiab ua rau hom valve no ruaj khov dua.Lub neej kev pab cuam tau ntev heev, thiab qhov tsis zoo ntawm cov teeb meem rusting raug tshem tawm.
