Khoom siv
Alkali ntau lawm kev lag luam, chlor-alkali chemical kev lag luam thiab organic chloride ntau lawm, kev lag luam ua zaub mov, kub halogen thiab ntsev corrosive ib puag ncig, hluav taws xob ntsuas qhov chaw, dej kho, ntau yam muaj zog alkali resistant khoom.
Lub cev thiab tshuaj lom neeg ntawm nickel:
Nickel yog cov nyiaj dawb-dawb ferromagnetic hlau thiab yog cov khoom tseem ceeb ntawm ntau cov khoom sib nqus.
Nickel kuj muaj oxidation zoo thiab muaj zog corrosion kuj.
Nickel yog nyiaj-dawb ferromagnetic hlau. Qhov ceev 8.9 g / cm3, melting point 1455 degree.
Nickel yog hlau nplaum thiab yog cov khoom tseem ceeb ntawm ntau cov khoom sib nqus.
Nickel kuj muaj oxidation zoo. Nyob rau hauv cov huab cua, ib tug NiO zaj duab xis tsim nyob rau saum npoo ntawm npib tsib xee, uas yuav tiv thaiv tau oxidation ntxiv.
Kev sim tau ua pov thawj tias npib tsib xee nrog purity ntawm 99% yuav tsis xeb hauv 20 xyoo. Nickel muaj zog corrosion kuj, tshwj xeeb tshaj yog tiv thaiv caustic alkali. Nyob rau hauv 50% boiling caustic soda tov, tus nqi corrosion ntawm npib tsib xee tsis tshaj 25 microns ib xyoo.
Nickel kuj muaj lub zog zoo thiab plasticity thiab tuaj yeem tiv taus ntau yam txheej txheem siab.
Nickel yog siv ntau ntau los ua ntau hom stainless hlau, mos magnetic alloys thiab alloy structural steels.
Nickel yog cov khoom tseem ceeb rau kev tsim cov nickel-cadmium, nickel-hydrogen roj teeb thiab nickel mesh.
Nickel kuj tau siv dav hauv electroplating thiab catalyst ntau lawm.
Nickel yog siv ntau ntau los ua ntau hom stainless hlau thiab mos sib nqus hlau nplaum (uas tuaj yeem nkag siab yooj yim xws li: cov hlau nplaum sib nqus uas yooj yim magnetized nyob rau hauv qhov kev txiav txim ntawm sab nraud magnetic teb thiab nws qhov sib nqus induction siv (magnetic induction) pib ploj. tom qab cov hlau nplaum sab nraud raug tshem tawm.
