Lub tuam txhab tuaj yeem hloov kho ntau yam ntawm daim iav stainless hlau phaj, txais tos xa email nug kuv
1. Nyob rau saum npoo ntawm stainless hlau, muaj deposits ntawm hmoov av los yog heterogeneous hlau hais uas muaj lwm yam hlau ntsiab.Nyob rau hauv cov huab cua ntub, cov dej condensed nruab nrab ntawm cov deposits thiab stainless hlau txuas ob mus rau hauv lub micro-roj teeb, uas ua rau cov tshuaj tiv thaiv electrochemical, cov yeeb yaj kiab tiv thaiv puas, hu ua electrochemical corrosion.
2. Organic kua txiv (xws li zaub, noodle kua zaub, hnoos qeev, thiab lwm yam) ua raws li cov hlau tsis huv.Nyob rau hauv lub xub ntiag ntawm dej thiab oxygen, organic acids yog tsim, thiab organic acids yuav corrode hlau nto rau lub sij hawm ntev.
3. Qhov saum npoo ntawm stainless hlau adheres rau cov khoom uas muaj acids, alkalis thiab ntsev (xws li alkali dej thiab txiv qaub dej txaws los ntawm cov phab ntsa kho kom zoo nkauj), ua rau lub zos corrosion.
4. Nyob rau hauv cov huab cua phem (xws li cov huab cua uas muaj ib tug loj npaum li cas ntawm sulfide, carbon oxide, nitrogen oxide), nyob rau hauv lub xub ntiag ntawm condensed dej, tsim sulfuric acid, nitric acid, acetic acid kua me ntsis, ua rau cov tshuaj corrosion. saum toj no tej yam kev mob yuav ua rau cov zaj duab xis tiv thaiv ntawm stainless hlau nto.Kev puas tsuaj ua rau xeb.
Kev tiv thaiv corrosion ntawm stainless hlau tsuas yog nyob ntawm nws cov alloy muaj pes tsawg leeg (chromium, nickel, titanium, silicon, aluminium, manganese, thiab lwm yam) thiab cov qauv sab hauv, thiab lub luag haujlwm tseem ceeb yog chromium.Chromium muaj cov tshuaj lom neeg ruaj khov thiab tuaj yeem tsim cov yeeb yaj kiab passivation ntawm cov hlau kom cais cov hlau los ntawm lub ntiaj teb sab nraud, tiv thaiv cov phaj hlau los ntawm kev oxidized, thiab ua kom cov hlau tsis kam tiv thaiv.Tom qab cov zaj duab xis passivation raug rhuav tshem, qhov corrosion kuj txo.
Stainless hlau phaj feem ntau yog ib lo lus dav dav rau stainless hlau phaj thiab acid-resistant steel phaj.Taw qhia thaum pib ntawm lub xyoo pua no, txoj kev loj hlob ntawm stainless hlau phaj tau tso ib qho tseem ceeb ntawm cov khoom siv thiab cov txheej txheem rau kev txhim kho kev lag luam niaj hnub thiab kev tshawb fawb thiab thev naus laus zis.Muaj ntau ntau hom stainless hlau phaj nrog cov khoom sib txawv.Nws tau maj mam tsim ntau pawg hauv txoj kev txhim kho.Raws li cov qauv, nws tau muab faib ua plaub pawg: austenitic stainless hlau, martensitic stainless hlau (xws li nag lossis daus hardening stainless hlau), ferritic stainless hlau, thiab austenitic ntxiv rau ferritic duplex stainless hlau.Cov tshuaj lom neeg muaj pes tsawg leeg lossis qee cov yam ntxwv hauv cov phaj hlau tau muab faib ua chromium stainless hlau phaj, chromium nickel stainless hlau phaj, chromium nickel molybdenum stainless hlau phaj, qis carbon stainless hlau phaj, siab molybdenum stainless hlau phaj, siab purity stainless hlau phaj. , thiab lwm yam raws li cov yam ntxwv ntawm kev ua tau zoo thiab kev siv ntawm cov hlau phaj, nws muab faib ua nitric acid-resistant stainless hlau phaj, sulfuric acid-resistant stainless hlau phaj, pitting corrosion-resistant stainless hlau phaj, kev nyuaj siab corrosion-resistant stainless hlau phaj. , high-strength stainless hlau phaj, thiab lwm yam. Raws li cov yam ntxwv ntawm cov hlau phaj, nws tau muab faib ua tsis tshua muaj kub stainless hlau phaj, tsis-magnetic stainless hlau phaj, dawb-txiav stainless hlau phaj, superplastic stainless hlau phaj, thiab lwm yam. . Cov txheej txheem kev faib tawm feem ntau yog muab faib raws li cov yam ntxwv ntawm cov phaj hlau, cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov phaj steel thiab kev sib xyaw ua ke ntawm ob.Feem ntau muab faib ua martensitic stainless hlau, ferritic stainless hlau, austenitic stainless hlau, duplex stainless hlau thiab nag lossis daus hardening stainless hlau, thiab lwm yam los yog muab faib ua ob pawg: chromium stainless hlau thiab nickel stainless hlau.Kev siv ntau yam Kev siv: cov khoom siv pulp thiab ntawv cov khoom siv hluav taws xob sib hloov, cov khoom siv kho tshuab, cov khoom siv dyeing, cov khoom siv ua yeeb yaj kiab, cov kav dej, cov khoom siv sab nrauv rau cov tsev nyob hauv ntug dej hiav txwv, thiab lwm yam.
Stainless hlau phaj muaj ib tug du nto, siab plasticity, toughness thiab mechanical zog, thiab yog resistant rau corrosion los ntawm acids, alkaline gases, kev daws teeb meem thiab lwm yam xov xwm.Nws yog cov hlau alloy uas tsis xeb yooj yim, tab sis tsis muaj xeb kiag li.
