[1] Txawv sib txawv hauv lub cev thiab tshuaj
Txawm hais tias chromium (CR) thiab npib tsib (NI) yog qhov sib txawv ntawm cov hlau hloov, xws li kev sib txawv ntawm kev sib txawv ntawm lawv, feem ntau yog concentrated nyob rau hauv cov nram no sib xws:
Qhov sib txawv hauv qhov ntom ntom: lub ntom ntawm chromium yog 7.1,9 g / cm {{3.
Qhov txawv txav ntawm melting thiab cov ntsiab lus boiling: lub ntsiab lus melting ntawm chromium yog siab npaum li xyoo 1907 degrees yog siab npaum li 2672 degrees Celsius; Nyob rau hauv sib piv, lub suab me me ntawm Nickel yog 1453 degrees Celsius thiab qhov cub npau yog 2732 degrees Celsius.
Qhov sib txawv hauv cov khoom siv tshuaj sib txawv: cov chromium paub txog nws txoj kev ua tau zoo heev thiab muaj feem ntau siv hauv kev tsim cov hlau stainless, cov log thiab dav hlau; Thaum lub nroog npib tsib xee tau siv dav hauv kev tsim cov khoom siv kub, casting pwm vim nws cov roj kub yas ua kom zoo thiab tawv.
Qhov sib txawv hauv kev thov hauv cov hlau stainless: chromium plays lub luag haujlwm hauv kev tsim cov roj chomium oxide uas tsis yooj yim hauv cov hlau stainless; Thaum Nickel tuaj yeem txhim kho lub zog, ductility thiab corrosion tsis kam ntawm cov khoom .
Qhov sib txawv hauv cov khoom sib txawv: chromium muaj cov khoom sib nqus muaj zog, yog li cov khoom siv uas tuaj yeem raug tshuaj tiv thaiv yooj yim los ntawm cov hlau nplaum ntau muaj ntau cov chromium .
Qhov sib txawv hauv cov xim tsos: cov khoom kho nrog Nickel plating muaj lub ntsej muag-dawb thiab daj; Thaum cov khoom kho nrog chrome plating muaj lub ntsej muag zoo nkauj thiab ntsej muag xiav .
[2] Txawv siv
Chromium thiab Nickel muaj qhov sib txawv tseem ceeb hauv kev thov, uas tau cuam tshuam tshwj xeeb hauv cov hauv qab no:
Cov chaw thov lub ntsiab ntawm chromium: kev tsim khoom ntawm stainless hlau, hlau chrome qhov chaw, log thiab aircraft {}}
Cov chaw thov npe tseem ceeb ntawm Nickel: Qhov tsim cov khoom siv kub, casting pwm thiab cov khoom siv roj av hauv lub hwj huam teb .
Qhov sib txawv hauv kev thov cov khoom siv: Daim ntawv thov ntawm chromium yog feem ntau concentrated hauv metallurgy, kev lag luam chemical, tshuab thiab nqus; Thaum lub sijhawm Nickel muaj ntau dua, npog kev kho mob, kev lag luam, txua hluav taws xob thiab lwm cov liaj teb.
Hauv cov ntsiab lus, txawm hais tias Chromium thiab Nickel zoo sib xws hauv lawv cov kev siv lub cev thiab cov tshuaj sib txawv, cov khoom siv sib txawv hauv kev tsim tawm, lub neej thiab thev naus laus zis.
Kev npaj txoj kev ntawm Nickel hais
Sol-gel txoj kev, cov thev naus laus zis ua haujlwm hauv cov khoom siv ua ntej, thiab cov khoom siv hydraulic Txhawm rau ua kom ruaj khov kho pob tshab sol System {{4 4} {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Thaum mus kom qhuav thiab sintering solidification, molecular thiab txawm tias cov ntaub ntawv nano-cov khoom siv, xws li cov nickel hais, tuaj yeem npaj .
