Cov txheej txheem ntau lawm ntawm lub ntsej muag ntshiab npib

Raws li cov khoom lag luam tseem ceeb, cov xov tooj liab uas muaj cov xov tooj no tau siv dav hauv ntau thaj teb vim nws lub cev thiab tshuaj lom neeg zoo. Npib Nickel yog yog ua los ntawm Nickel keeb thiab feem ntau muaj siab corrosion tsis kam, zoo heev neeg kho cov khoom siv.

I. Cov yam ntxwv yooj yim

1. Tshuaj lom neeg

Nws cov tshuaj tua cov khoom tseem ceeb muaj xws li:

Corrosion Kuj: Lub npib ntshiab: Cov neeg ua yeeb yaj kiab tiv thaiv oxide zaj duab xis hauv huab cua, uas ua rau nws muaj cov tshuaj tiv thaiv corrosion zoo tshaj plaws. Nws tuaj yeem tiv thaiv corrosion los ntawm ntau yam ntawm cov acids, alkalis thiab ntsev, uas ua rau cov khoom no zoo nyob hauv cov chaw hnyav.

Oxidation tsis kam: raws li cov kev mob siab, Nickel hlau tuaj yeem ruaj khov thiab tsis yooj yim oxidized. Nickel Oxide kuj muaj cov kev ruaj khov zoo thaum muaj kev kub siab, ua kom muaj kev pabcuam ntev ntawm Nickel hlau.

2. Lub zog lub cev

Nws muaj cov khoom siv lub cev zoo heev:

Kev ua haujlwm siab: Npib xaim hluav taws xob muaj qhov ua tau zoo dua ntau cov hlau thiab feem ntau siv los ua cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob.

Cov khoom siv zoo: Nickel xo xaim muaj lub zog zoo thiab muaj peev xwm tswj tau cov cuab yeej ruaj khov kho hauv qab cov kev kub siab thiab cov xwm txheej siab. Nws lub zog tensile thiab ductility ua nws haum rau ntau qhov chaw muaj kev ntxhov siab.

3. Thermal Khoom

Siab melting taw tes: ntshiab nickel muaj lub siab melting point, uas ua rau cov khoom muaj kev ruaj khov zoo nyob hauv ib puag ncig kub siab.

Cov thermal zoo heev: npib xaim hluav taws xob muaj qhov siab thermal conductivity thiab tuaj yeem hloov kho cov ntu uas yuav tsum tau ua kom sov.

2. Cov txheej txheem ntau lawm ntawm Cov Ntshiab Nickel xaim

1. Cov Khoom Siv Khoom Raw

Npaj cov khoom noj muaj menyuam loj-purity npib hlau raw. Nickel ore yog smelted thiab purified kom tau txais high-purified ailth hlau, uas yuav raug siv los ua cov khoom siv yooj yim rau kev tsim khoom Nickel hlau.

2. Melting thiab casting

High-purity npib hlau yog melted rau hauv kua thiab tom qab cam khwb cia. Cov txheej txheem casting tuaj yeem siv pwm pov lossis txuas ntxiv casting los cam cov pas nrig tuab rau cov txheej txheem tom ntej.

3. Xaim kos duab

Lub cam khwb cia nickel rods raug txiav rau hauv qhov ntev thiab ces hlau kos. Cov txheej txheem hlau kos duab maj mam tig cov pas nrig npib tsib mus rau hauv cov me me npib npib tsib xee cov xov hlau los ntawm kev txuas ntxiv ncab thiab compression. Cov txheej txheem no yuav tsum tau nqa tawm hauv qhov kub thiab txias kom ntseeg tau tias qhov kev sib txuam thiab ruaj khov ntawm npib tsib xee.

4. Annealing Kev Kho Mob

Lub npib tsib xee txuas tom qab kev kos duab feem ntau yuav tsum tau annealed kom tshem tawm cov kev ntxhov siab sab hauv lub sijhawm thaum lub sijhawm kos duab. Kev qhia annealing yog nqa tawm ntawm qhov kub tshwj xeeb, uas tuaj yeem txhim kho cov khoom siv tshuab thiab kev sib txuas ntawm cov xee npib tsib xee thiab ua kom nws qhov ruaj khov hauv cov ntawv thov txuas ntxiv.

5. Nto Kho

Txhawm rau txhim kho cov xeb tsis kam thiab tsos ntawm cov ntshiab npib tsib xee xaim xaim hluav taws xob, kev kho deg feem ntau yuav tsum muaj. Qhov no muaj xws li cov txheej txheem xws li kev tu, polishing lossis txheej txheej tiv thaiv kom ntseeg tau tias cov npib tsib xee thiab dawb ntawm qhov tsis xws luag.

Ntshiab Nickel xov yog qhov tseem ceeb ntawm kev lag luam kev lag luam thiab cov khoom siv siab thiab tshuaj lom neeg thiab ntau yam kev siv tshuaj. Los ntawm kev ua tsis tu ncua ua kom tau cov txheej txheem ntau lawm thiab txhim kho cov ntaub ntawv tshiab, kev ua tau zoo thiab kev ua lag luam tau txuas ntxiv mus txuas ntxiv.
