3. Vim li cas NI200 tshwj xeeb tshwj xeeb tiv taus corrosion?
Teb:
Ni200 muaj cov ntsiab lus corrosion zoo tshaj plaws vim nws cov ntsiab lus nickel siab. Qee cov ntsiab lus tseem ceeb ua rau nws cov kev tiv thaiv muaj xws li:
Tsis-oxidizing tawm tsam:Ni200 ua tau zoo hauv kev txo qhov chaw ib puag ncig, xws li alkaline lossis acid daws, qhov twg ntau alloys yuav txwv.
Chloride Kuj:Nws muaj cov muaj zog tsis kam mus rau chloride-inducles corroside, tshwj xeeb hauv ib puag ncig zoo li dej hiav txwv lossis brine.
Ruaj khov txheej txheem:Tus ntshiab npib tsib xee nyob rau hauv Ni200 ua tiav, tus kheej kho oxide oxide txheej, muab cov nyom tiv thaiv oxidation thiab corrosion nyob rau ntau qhov chaw hnyav.
Zoo heev rau kev ntxhov siab-corrosion tawg:Ni200 muaj kev ntxhov siab heev rau kev ntxhov siab-corrosion cracking nyob rau hauv chloride ib puag ncig, tsis zoo li ntau ntau lwm yam xws li stainless hlau.
4. Dab tsi yog qhov tseem ceeb ntawm kev siv Ni200 tubing?
Teb:
Qhov tseem ceeb ntawm qhov zoo ntawm kev siv Ni200 tubing suav nrog:
Zoo heev corrosion:Tshwj xeeb hauv kev txo cov kua qaub, cov kev daws teeb meem alkaline, thiab chloride ib puag ncig zoo li dej hiav txwv.
Siab Purity:Nws ze li ze li Nickel muaj pes tsawg leeg ua rau nws zoo tagnrho rau kev siv cov qib impurity yuav tsum tsawg.
Zoo heev:Ni200 yog condile heev thiab tuaj yeem tsim tau yooj yim tsim rau hauv cov hlab lossis kav dej, ua kom haum rau cov qauv tsim nyuaj.
Zoo thermal thiab hluav taws xob conductivity:Zoo li lwm tus nickel alloys, Ni200 muaj qhov kub thiab hluav taws xob ua kom sov thiab hluav taws xob, uas yog qhov muaj txiaj ntsig hauv kev siv fais fab.
Xav muaj zog txhua yam:Txawm hais tias nws muaj kev coj dawb huv, NI200 tswj hwm txoj kev ua tau zoo, tso cai rau nws tiv thaiv kev ntxhov siab thiab siab hauv kev siv cov ntawv thov.
5. Cov kev txwv lossis cov nyom li cas thaum siv Ni200 Nickel Alloy?
Teb:
Thaum Ni200 muaj ntau cov txiaj ntsig, muaj qee qhov kev sib tw thiab cov kev txwv:
Txwv tsis pub siv lub zog-kub zog:Thaum nws ua tau zoo nyob rau hauv nruab nrab kub, Ni200 tsis haum rau cov ntawv thov kub siab piv tau piv rau lwm tus nickel alloys zoo li Inconel. Nws muaj qhov qis dua melting point thiab cov neeg kho tshuab hluav taws xob tsis muaj zog ntawm cov ntsuas kub.
Txwv tsis kam mus rau oxidizing ib puag ncig:Ni200 tsis zoo rau hauv cov oxidly oxidizing ib puag ncig (piv txwv li concentrated nitric acid) piv rau lwm cov alloys zoo li hastelloy lossis inconel.
Nqi:Nickel alloys, tshwj xeeb yog cov uas muaj siab purity zoo li ni200, zoo li yuav kim dua lwm cov ntaub ntawv ib yam li hlau hlau.
Machining nyuaj:Ni200, zoo li cov hlau zoo nkauj, tuaj yeem ua haujlwm-harden thaum lub tshuab machining, ua rau nws nyuaj txiav lossis daim ntawv tsis muaj siv cov cuab yeej tshwj xeeb.
Tsawg lub zog piv rau high-alloy nickel alloys:Ni200 lub zog thiab kev tawm tsam mus rau high-kub nkag tsis yog li ntau li lwm cov nickel-based alloys uas muaj cov chromium lossis molybdenum.
