Qhov tseem ceeb - Nickel vs Stainless hlau
Nickel thiab stainless hlau yog ob hom hlau sib txawv thiab qhov sib txawv ntawm lawv tuaj yeem raug sau tseg raws li lawv cov khoom sib txawv thiab kev siv. Qhov sib txawv tseem ceeb ntawm ob cov hlau no yog, Nickel yog cov tshuaj dawb huv hauv d-block nrog qee cov khoom tshwj xeeb thaum stainless hlau yog cov hlau alloy uas muaj hlau, Chromium, thiab Nickel. Cov muaj pes tsawg leeg ntawm peb lub ntsiab sib txawv hauv cov hlau tsis muaj steel; npib tsib xee txhawb qhov tsawg kawg nkaus ntawm qhov muaj pes tsawg leeg. Cov ntshiab Nickel oxidizes maj mam ntawm chav tsev kub; Yog li ntawd nws yog ib tug kuj corrosion resistant keeb. Vim nws corrosion kuj, nws yog siv nyob rau hauv zus tau tej cov corrosion resistant hlau alloys. Ib qho piv txwv yog stainless hlau.
Nickel yog dab tsi?
Nickel yog cov khoom siv tshuaj (cim Ni thiab atomic naj npawb 28) nyob rau hauv lub rooj sib tham thiab cov hlau hloov pauv hauv d-block. Nickel yog siv nyob rau hauv ntau qhov chaw rau kev lag luam kev siv; Piv txwv li, hauv cov tsev, cov khoom siv dej, cov khoom siv hluav taws xob, kev lag luam tshuaj, kev lag luam thauj thiab khoom siv kho mob. Lub ntsiab yog vim li cas rau ntau yam ntawm daim ntawv thov no yog vim nws cov yam ntxwv ntawm ntau yam khoom. Hauv lwm lo lus, Nickel muaj qhov sib xyaw ua ke ntawm cov khoom; Nws yog cov hlau nplaum uas muaj qhov kub kub (1453 0 C), muaj cov khoom sib nqus ntawm chav tsev kub, thiab tuaj yeem siv los ua cov khoom siv rau qee cov tshuaj tiv thaiv.
Stainless Hlau yog dab tsi?
Stainless hlau yog cov hlau alloy uas yog tsim los ntawm kev sib xyaw ua ke ntawm ntau cov hlau; hlau, chromium, thiab nickel. Cov cuab yeej tseem ceeb ntawm stainless hlau yog nws cov corrosion thiab stain kuj; lawv yog cov khoom siv ruaj khov thiab siv tau ntau yam xws li lub tsev, kev thauj mus los, kev tuav zaub mov thiab dej haus, tshuaj nroj tsuag, thiab khoom siv kho mob. Stainless hlau yog qhov ruaj khov, thiab nws xav tau tus nqi kho qis; yog li ntawd nws yog siv nyob rau hauv ib tug ntau yam ntawm daim ntawv thov nyob rau hauv ntau lub teb.
Qhov txawv ntawm Nickel thiab Stainless Hlau yog dab tsi?
Kev sib xyaw ntawm Nickel thiab Stainless Hlau
Nickel: Nickel yog cov tshuaj ntshiab huv; nws kuj yog ib tug tswv cuab ntawm kev hloov hlau pawg. Nickel muaj tsib qhov tshwm sim nyob ruaj khov isotopes; 58Ni, 60Ni, 61Ni, 62 Ni, and 64Ni. Qhov ntau tshaj isotope yog 58Ni, thiab nws qhov tshwm sim ntuj yog li 68.077%.
Stainless Steel: Stainless hlau yog kev sib xyaw ntawm hlau (Fe), Chromium (Cr) thiab Nickel (Ni). Feem ntau, stainless hlau muaj cov hlau ntau thiab tsawg dua ntawm cov nickel (8% -10%). Chromium yog lub thib ob loj tshaj plaws nyob rau hauv nws muaj pes tsawg leeg. Kev siv Nickel hauv stainless hlau tsis raug nqi. Yog li ntawd, manufacturers sim siv tus nqi tsawg kawg nkaus ntawm Nickel.
Khoom ntawm Nickel thiab Stainless Hlau
Nickel: Nickel muaj cov khoom tshwj xeeb; Piv txwv li, nws yog cov hlau nplaum uas muaj cov khoom sib nqus. Nws oxidizes maj mam nyob rau hauv chav tsev kub, nyob rau hauv lwm yam lus, nws yog ib tug ruaj khov nyob rau hauv chav tsev kub thiab resists corrosion. Nickel muaj qhov kub kub kub, thiab nws tuaj yeem siv los ua cov khoom siv hauv qee qhov kev lag luam tshuaj.
Stainless Steel: Cov cuab yeej tseem ceeb tshaj plaws ntawm stainless hlau yog nws cov corrosion kuj thiab resistant rau stain. Tsis tas li ntawd, nws yog cov hlau uas muaj zog thiab ruaj khov rau ntau xyoo nrog tus nqi saib xyuas qis. Stainless hlau yog ib puag ncig-phooj ywg cov khoom vim nws tuaj yeem siv tau tag nrho.
Daim ntawv thov ntawm Nickel thiab Stainless Hlau
Nickel: Feem ntau ntawm Nickel ntau lawm yog siv los tsim Nickel steels; Raws li ib feem, nws yog kwv yees li 46% ntawm tag nrho cov khoom. Tsis tas li ntawd, nws yog siv los tsim cov tsis-ferrous alloys thiab super alloys thiab hauv electroplating. Muaj ntau ntau daim ntawv thov tshwj xeeb ntawm Nickel; los tsim cov hlau nplaum, npib, cov hlua guitar, roj teeb rechargeable thiab microphone capsules.
Stainless Steel: Stainless hlau yog siv los tsim cov khoom ua noj, tais diav, khoom siv hauv tsev, khoom siv kho mob thiab cov hniav nyiaj hniav kub.
