Teb:
Ni200 thiab NI201 Cov daim phiaj no Nickel yog siv nyob rau hauv ntau yam kev lag luam, suav nrog:
Kev Lag Luam(xws li, reactors, kev sib pauv cua sov, thiab pipelines nthuav tawm rau corrosive tshuaj)
Ib tug tub rog(Piv txwv, cov khoom siv uas yuav tsum muaj siab thermal ruaj thiab corrosion tsis kam)
Khoom siv hluav taws xob(piv txwv li, roj teeb ntau lawm, muaj peev xwm siv hluav taws xob, thiab kev siv hluav taws xob siab)
Tus sawv cev ua tub rog(xws li, feem uas raug rau dej hiav txwv lossis lwm qhov chaw nruab nrab)
Kev Ua Noj(xws li, cov cuab yeej siv sib chwv nrog zaub mov thiab dej haus, vim nws cov tsis muaj tshuaj lom thiab xeb-resistant xwm)
Cov alloys 'tshwj xeeb corrosion tiv taus rau ib puag ncig uas cov ntaub ntawv muaj kuab tshuaj ua phem lossis kub.
3. Dab tsi yog qhov zoo ntawm kev siv Ni200 / Ni201 daim hlau nrog lub ntsej muag ci ci?
Teb:
A Ci ci deg tiavNtawm Ni200 lossis NI201 daim hlau muaj ob peb qhov zoo:
Txhim Kho Kom Zoo Nkauj: Lub ci ci, du nto kom cov tsos ntawm cov khoom siv, ua rau lawv pom kev pom zoo rau cov neeg siv khoom lossis cov ntawv thov siab.
Zoo dua corrosion tsis kam: Lub chaw ci ci ci li cas txhais tau tias tsawg dua kev tiv thaiv kev xeb vim tias muaj kev phom sij uas tsis muaj tshuaj lom neeg.
Yooj yim ntawm cov fabrication: Ci ntsa iab, du surfaces pub rau machining zoo dua, vuam, thiab sib sau ua, ua rau cov khoom siv yooj yim rau cov txheej txheem lossis cov khoom siv.
Txhim kho kev ua tau zoo: Lub polished saum npoo txo kev sib txhuam thiab hnav, ua rau nws haum ntau rau cov ntawv thov uas muaj kev cuam tshuam nrog lwm cov ntaub ntawv yog qhov tseem ceeb.
4. Dab tsi yog cov tuab tuab muaj rau Ni200 / Ni201 Cov ntawv ntshiab Npib Daim Hlau, thiab cov tuab npaum li cas cuam tshuam rau lawv qhov kev ua tau zoo?
Teb:
NI2 {{0 0 thiab ni201 Cov ntawv ntshiab ntawm Nickel yog feem ntau muaj nyob rau hauv ntau thicknesses, los ntawm cov phiaj thickness (piv txwv li, 10mm lossis ntau dua). Lub thickness ntawm lub phaj ua lub luag haujlwm hauv nws cov yam ntxwv thiab haum rau cov ntawv thov sib txawv:
Daim hlau nyias: Muab cov khoom siv hloov tau thiab feem ntau siv hauv cov ntawv thov lossis cov khoom siv uas yuav tsum tau ua raws li cov duab tshwj xeeb. Daim phiaj plhawv nyias tseem muaj ntau dua rau cov ntawv thov hauv cov khoom siv hluav taws xob lossis cov phab ntsa nyias nyias.
Tuab daim hlau: Muab cov tshuab ua kom zoo dua qub thiab tiv thaiv kom hnav thiab kev ntxhov siab, ua rau lawv haum rau cov txheej txheem kev ua haujlwm hnyav uas yuav tsum muaj.
Qhov kev xaiv ntawm cov tuab nyob ntawm cov ntawv thov tshwj xeeb thiab txawm hais tias muaj zog lossis hloov tau yog qhov tseem ceeb.
5. Tus nqi Ni200 thiab NI201 ntshiab Nickel daim phiaj sib piv rau lwm cov ntaub ntawv li stainless hlau lossis titanium?
Teb:
Ni200 thiab ni201 ntshiab nickel phaj yuav uapheej yig duatshaj li kev ua haujlwm siab alloys zoo li titanium tab siskim duatshaj li stainless hlau. Txawm li cas los xij, tus nqi yog kev ncaj ncees los ntawm cov khoom tshwj xeeb ntawm cov ntshiab npib tsib xee, xws li nwsZoo heev corrosion, thermal stability, thiab yooj yim ntawm vuamCov. Tus nqi kuj tseem yuav sib txawv raws li lub phaj tuab, nto tiav, thiab ntim ntawm qhov kev txiav txim. Rau cov ntawv thov uas corrosion tsis kam thiab cov khoom ruaj khov nyob rau hauv kev ua yeeb yam (xws li aerospace
