Stainless hlau tub yees: Cov yam ntxwv ntawm cov khoom tseem ceeb thiab kev xaiv xaiv

Nyob rau hauv cov txheej txheem ntawm stainless hlau tub yees, kev xaiv ntawm cov ntaub ntawv ncaj qha txiav txim siab cov cuab yeej corrosion kuj, kev ua haujlwm tu cev, lub zog muaj zog, thiab kev pab cuam lub neej.As yog ib qho tseem ceeb ntawm cov khoom noj khoom haus txias, qib thiab kev ua cov hlau stainless siv hauv cov tub yees tsis tsuas yog cuam tshuam rau cov tsos thiab kev ntxhib los mos tab sis kuj yog qib ntawm cov zaub mov kev nyab xeeb thiab kev ua haujlwm zoo. Kev nkag siab txog nws cov yam ntxwv ntawm cov khoom tseem ceeb yuav pab txiav txim siab paub ntau ntxiv thaum kev yuav khoom thiab siv.

Tam sim no, lub ntsiab stainless hlau siv nyob rau hauv lub tub yees tsim yog austenitic stainless hlau, tshwj xeeb tshaj yog qib 304 thiab 316. 304 stainless hlau muaj li ntawm 18% chromium thiab 8% npib tsib xee, muaj zoo corrosion kuj thiab formability. Nws tuaj yeem tiv taus corrosion ntawm feem ntau cov zaub mov acids, ntsev, thiab roj. Nws nto yog yooj yim polished rau daim iav los yog matte tiav, yooj yim ntxuav thiab inhibiting kab mob loj hlob. Yog li ntawd, nws yog dav siv nyob rau hauv lub puab liners, txheej casings, thiab cov khoom ntawm tub yees, khov, thiab tso saib tub yees . 316 stainless hlau ntxiv kwv yees li 2%-3% molybdenum, ho txhim kho nws tsis kam mus rau pitting thiab crevice corrosion nyob rau hauv chloride ib puag ncig. Nws yog qhov tsim nyog rau kev ua haujlwm hnyav xws li thaj chaw ntug dej hiav txwv uas muaj cov av noo siab los yog nquag sib cuag nrog dej ntsev thiab tshuaj tua kab mob. Txawm hais tias kim dua me ntsis, nws muaj qhov txiaj ntsig zoo hauv kev ua zaub mov tshwj xeeb lossis qhov chaw huv huv.

Cov txheej txheem txheej txheem ntawm lub tub yees vaj huam sib luag tseem cuam tshuam rau kev ua haujlwm kawg. Feem ntau, cov ntawv txias-cov ntawv tsis muaj steel hlau tau txais kev kho mob los txhim kho toughness thiab corrosion kuj. Qhov saum npoo tuaj yeem kho nrog ntau txoj hauv kev xws li txhuam hniav, xuab zeb blasting, lossis electropolishing, ua tau raws li qhov yuav tsum tau ua kom zoo nkauj thaum tswj microbial adhesion los ntawm altering nto roughness. Welded thaj chaw feem ntau siv argon arc vuam nrog argon roj tiv thaiv rau sab nraub qaum kom tiv thaiv kev xeb hauv zos los ntawm chromium depletion ntawm cov ciam teb ntawm qhov kub thiab txias. Acid pickling thiab passivation txheej txheem kuj tseem siv los kho cov corrosion kuj ntawm cov welds. Rau cov khoom siv tseem ceeb xws li thauj khoom-cov kabmob thiab cov pob khawm, ntxiv rau kev xaiv cov qib uas tsim nyog, yuav tsum tau them nyiaj rau thickness thiab txhawb cov tav tsim kom muaj kev ruaj ntseg nyob rau hauv ntev - lub sij hawm load thiab kub siab.

Hais txog kev ua raws li kev nyiam huv, zaub mov- qib stainless hlau yuav tsum ua tau raws li cov qauv hauv lub tebchaws thiab cov kev cai hauv kev lag luam, kom ntseeg tau tias kev tsiv teb tsaws ntawm cov khoom tsis zoo xws li txhuas thiab cadmium qis dua qhov kev txwv, thiab qhov roughness thiab kev sib koom ua ke ua tau yooj yim - kev tu huv. Qee lub tub yees txias siab - kawg siv cov tshuaj tua kab mob stainless hlau, suav nrog cov tshuaj tua kab mob xws li nyiaj ions thaum lub sij hawm smelting los yog txheej txheej los tiv thaiv kev loj hlob ntawm cov kab mob pathogenic, ntxiv dag zog rau kev nyab xeeb ntawm cov khoom noj.

Zuag qhia tag nrho, 304 thiab 316 stainless hlau, nrog rau lawv cov kev tiv thaiv corrosion thiab tsim kom zoo, tsim cov khoom tseem ceeb rau cov tub yees stainless hlau tam sim no. Los ntawm kev xaiv cov khoom tsim nyog raws li kev ua haujlwm thiab kev sib xyaw ua ke nrog kev ua haujlwm zoo thiab kev kho saum npoo, qhov zoo tshaj plaws sib npaug ntawm kev ua haujlwm zoo, kev nyiam huv, thiab tus nqi - tuaj yeem ua tiav, muab kev txhawb nqa ruaj khov rau kev ua haujlwm ruaj khov ntawm cov khoom noj txias.
