Aquaculture thermostatic tso tsheb hlau luam, cov khoom noj pickling tso tsheb hlau luam, lub Hoobkas ncig cov kav dej txias thiab cov khoom siv hluav taws xob muaj hluav taws xob uas muaj cov tshuaj chloride ions thiab dilute cov kua qaub tsis muaj zog. Tsawg-cov pa roj carbon steel cua sov cov raj tau yooj yim raug xeb nkag thiab hluav taws xob xau txaus ntshai tom qab ua haujlwm luv luv -. High-kawg tiv thaiv-cov cua sov xws li titanium, quartz thiab PFA-coated heaters yuav tsum tau nqis peev loj thiab tsis haum rau loj - nplai xa tawm ntawm cov chaw tsim khoom me thiab nruab nrab- loj. Raws li cov molybdenum paub tab{10}} muaj cov hlau tsis muaj steel hlau, 316 stainless hlau cua sov raj tuav lub lag luam tseem ceeb ntawm cov khoom siv los tiv thaiv cov khoom siv cua sov. Ntau tus ntawm-cov kws tshaj lij thiab cov neeg yuav khoom tseem muaj kev tsis ntseeg txog nws cov txiaj ntsig kev pabcuam, kev txwv tsis pub siv thiab ntev-cov nqi ua haujlwm tau zoo piv nrog rau lwm cov khoom siv cua sov. Daim ntawv no tshuaj xyuas nws cov khoom zoo, cov txiaj ntsig ntawm kev siv thiab cov kev tsis zoo, nrog rau cov lus sib piv ntawm plaub lub ntsiab tiv thaiv{17}}cov khoom cua sov.
Lub zog sib tw tseem ceeb ntawm 316 stainless hlau pib los ntawm cov khoom molybdenum ntxiv, uas cuam tshuam cov tshuaj chloride zoo -induced pitting corrosion - lub hauv paus ua rau cov cua sov tube tsis ua hauj lwm hauv ntsev- muaj dej ib puag ncig. Raws li kev rov ua cua sov thiab cua txias, qhov ntom ntom chromium oxide passivation zaj duab xis tsis tu ncua rau ntawm phab ntsa sab nrauv ntawm lub raj los ua ib qho kev tiv thaiv thiab tiv thaiv corrosive ions los ntawm eroding hlau substrate. Unlike ordinary 304 stainless steel that quickly generates dense corrosion pits under chloride erosion, 316 stainless steel maintains complete structural stability under long-term thermal shock. Nws zam kev khoov mus tas li deformation thiab sealing cov kab nrib pleb, thiaj li tiv thaiv cov kua infiltration thiab burnout ntawm cov xov hlau sab hauv. Tsis tas li ntawd, kev vuam zoo, khoov thiab txiav cov thev naus laus zis txhawb kev kho tshwj xeeb- zoo li cov cua kub cua kom hloov mus rau qhov nqaim thiab tsis sib xws ntawm ntau yam khoom siv ntau lawm.
Cov lus hauv qab no sib piv cov cim ua haujlwm tseem ceeb ntawm plaub los tiv thaiv -corrosion cua sov raj nyob rau hauv me me corrosive industrial ib puag ncig:
表格
| Cua sov Tube hom | Tsis muaj Acid & Chloride Resistance | Max Nruam Kev Pabcuam Kub | Cov qauv kev ruaj ntseg nyob rau hauv Thermal Cycles | Tag nrho Lifecycle Tus Nqi Ua Haujlwm |
|---|---|---|---|---|
| 316 Stainless hlau | Muaj zog tiv thaiv -pitting kev ua tau zoo | 550 degree | Zoo heev, nyuaj rau deform | Qhov zoo tshaj plaws sib npaug ntawm cov nqi thiab kev ua haujlwm |
| 304 Stainless hlau | Tsis muaj zog, nws yooj yim rau tawg pleb corrosion | 420 degree | Nruab nrab, yooj yim rau hnub nyoog thiab distort | Kev siv nyiaj ntau ntxiv |
| Ntshiab Titanium Heating Tube | Sab saum toj -tier comprehensive anti-corrosion peev | 770 degree | Ultra- ruaj khov kho tshuab | Siab heev ib - sij hawm yuav khoom tus nqi |
| Quartz cua sov Tube | Tsuas yog ruaj khov nyob rau hauv ib qho acidic nruab nrab | 1170 degree | Tsis tshua muaj zog nyob rau hauv kev sib tsoo thiab kev co | Kev hloov pauv tsis tu ncua ua rau cov nqi zais ntxiv |
Hauv kev ua haujlwm niaj hnub hauv lub Hoobkas, 316 stainless hlau cua sov raj coj cov txiaj ntsig kev lag luam tseem ceeb rau cov lag luam nrog ntau cov ntsiab lus cua sov. Titanium cua sov raj coj hnyav ib -lub sij hawm peev siab; quartz raj yog ib qho yooj yim tawg thaum lub sij hawm thauj mus los, installation thiab tu txhua hnub, ua rau cov nqi hloov pauv tas li. Pa 304 stainless hlau raj yuav tsum tau kaw ntau lawm rau kev soj ntsuam thiab hloov, accumulating ib tug loj npaum li cas ntawm kev ua hauj lwm thiab cov khoom nqi nyob rau hauv lub sij hawm ntev - tas mus li ntau lawm. Nyob rau hauv sib piv, kev txij nkawm txhua hnub ntawm 316 stainless hlau cua sov raj tsuas yog xav tau yooj yim deg so, zoo heev txo cov nqi khiav hauj lwm ntawm tag nrho cov cua kub.
Txawm li cas los xij, 316 stainless hlau muaj qhov txwv siv tau. Ntev - lub sij hawm immersion nyob rau hauv siab - kub concentrated muaj zog acid los yog acid-base tov corrosive kua yuav ua rau irreversible kev puas tsuaj rau nws nto passivation zaj duab xis, ua rau sai tube phab ntsa corrosion thiab scrappage. Rau cov chaw ua haujlwm hnyav hnyav, PFA qhwv cov cua sov lossis cov titanium cua sov raj yog lwm txoj hauv kev txhim khu kev qha. Yog tias qhov nruab nrab cua sov yog cov dej ntshiab deionized yam tsis muaj corrosive impurities, xaiv 304 stainless hlau tuaj yeem ua tau raws li qhov xav tau ntawm cov cua sov thiab zam cov khoom siv tsis tsim nyog.
Hauv cov ntsiab lus, nrog molybdenum- txhim kho cov tshuaj chloride, ruaj khov thermal thiab cov khoom siv kho tshuab, hloov kho kev ua haujlwm thiab kev ua haujlwm zoo, 316 stainless hlau cua sov cov raj yog cov khoom siv hluav taws xob zoo tshaj plaws thiab kev lag luam cua sov rau ntau tshaj 80% kev lag luam scenes nrog tsawg thiab nruab nrab corrosion txaus ntshai. Txawm hais tias tsis tuaj yeem hloov mus rau ultra- hnyav corrosive xov xwm, nws tuav lub hauv paus tsis tuaj yeem hloov pauv hauv kev lag luam dav dav los tiv thaiv -corrosion cua sov kev lag luam.
