Dab tsi yog qhov txawv ntawm nickel 200 thiab 201?
Nickel 200
Nickel 200 muaj cov khoom siv zoo heev nrog rau cov khoom siv zoo thiab kev sib txuas. Nws kuj muaj cov khoom sib nqus thiab magnetostrictive, siab thermal thiab hluav taws xob conductivity, tsis tshua muaj roj cov ntsiab lus thiab tsawg vapor siab. Nws tuaj yeem siv rau ntau qhov chaw nrog qhov kub thiab txias hauv qab 315 degree (600 degree F).
Nws tsis kam mus rau corrosive ib puag ncig tsis txwv rau txo cov ntsiab lus - txawm hais tias qhov no yog nws lub zog - raws li nws kuj ua tau zoo nyob rau hauv tej yam kev mob oxidizing.
Nickel 200 feem ntau siv hauv kev lag luam hluav taws xob. Qhov no yog kev lag luam evolving sai heev thiab cov khoom tshiab tau raug tsim los ntawm kev nrawm nrawm. Yog li ntawd, tsawg alloy nickel yog nyob rau hauv siab thov. Nickel 200 tuaj yeem siv rau ntau yam khoom xws li cov phaj anode, passive cathodes, plating rods, transistor vaj tse, thiab lwm yam. Nws kuj tseem muaj nyob rau hauv qee lub tshuab kho qhov muag, xws li cov siv hauv telescopes thiab infrared emitters hauv cov koob yees duab thiab cov tshuab soj ntsuam. Nws kuj tseem siv tau rau cov khoom cua sov thiab cov roj teeb sib txuas.
Muab cov khoom siv siab corrosion kuj, nws kuj tuaj yeem siv rau hauv cov khoom siv tshuaj thauj khoom, tswj lawv cov qauv thiab kev ncaj ncees txawm tias thaum tawm tsam los ntawm corrosive media. Qhov no ua kom yooj yim rau kev khaws cia thiab kev thauj mus los ntawm cov khoom tsis zoo. Ib yam li ntawd, Nickel 200 yog siv rau hauv kev ua zaub mov thiab cov khoom siv hluavtaws fiber ntau.
Nickel 200 kuj muaj qee yam siv hauv kev lag luam aerospace thiab kev siv tiv thaiv. Qhov no suav nrog cov khoom siv nyob rau hauv missile systems.
Nickel 201
Nickel 201 muaj ntau yam zoo sib xws rau Nickel 200. Nws yog qhov zoo dua rau kev siv nrog kub siab tshaj 315 degree (600 degree F). Tsis zoo li nws tus npawg Nickel 200, cov ntsiab lus qis dua txhais tau tias tsis muaj graphite yuav tsim thaum raug kub hnyiab rau lub sijhawm ntev.
Nws muaj lub hauv paus hardness thiab qis dua ua haujlwm hardening, uas ua rau nws haum rau spinning thiab txias sib sau. Nws muaj kev tiv thaiv corrosion zoo thiab feem ntau siv rau hauv kev kho cov dej qab zib caustic, qhov twg nws tsim cov oxide zaj duab xis los tiv thaiv nws.
Yog li ib yam uas Nickel 201 paub txog yog nws siv nyob rau hauv cov txheej txheem caustic concentration (chlor-alkali), uas yog siv nyob rau hauv ntau industries. Cov txheej txheem no tsim cov tshuaj chlorine thiab sodium hydroxide (caustic soda), thiab tag nrho cov haujlwm ua haujlwm yog corrosive heev. Nickel 200 muaj qhov tsis sib xws ntawm corrosion tsis kam thiab yog cov khoom siv dav siv hauv kev tsim cov khoom siv cathode. Nickel 200 kuj tuaj yeem siv rau hauv cov txheej txheem no, tab sis cov pa roj carbon tsawg nickel 201 tuaj yeem siv rau hauv qhov chaw kub dua. Peb piav qhia txog daim ntawv thov no kom ntxaws ntxiv ntawm no. Cov ntawv thov tshwj xeeb rau cov txheej txheem chlor-alkali suav nrog cov evaporators thiab cov khoom siv rho tawm.
Zoo li Nickel 200, Nickel 201 kuj tuaj yeem siv rau hauv kev lag luam ua zaub mov vim nws tsis kam mus rau distilled thiab dej ntuj. Nws pab tswj cov khoom purity, uas yog qhov tseem ceeb thaum tuav cov khoom noj.
Nickel 201 feem ntau yog siv rau hauv cov hlab ntsha-cov hlab ntsha uas tsim los kom muaj cov pa roj lossis cov kua dej ntawm lub siab uas txawv ntawm qhov siab ntawm ambient. Nws raug pom zoo rau ASME Boiler thiab Pressure Vessel Code, Tshooj VIII, Division I, rau qhov kub txog li 1250 degree F (kwv yees li 677 degree).
