Synthetic Cryolite Rau Casting |15096-52-3
Product Description:
Cryolite yog siv nyob rau hauv casting tam sim no.Cryolite kuj tseem siv tshwj xeeb hauv kev tsim cov hlau ductile.Cov lus qhia tseem ceeb yog raws li nram no:
1. Txau rau saum npoo ntawm cov hlau molten, tus nqi yog 0.1% -0.3%, thiab nws lub luag haujlwm yog tshem tawm slag thiab npog tag nrho.
Cryolite tuaj yeem dilute cov slag kom nws tuaj yeem khaws thiab tshem tawm.
Cryolite decomposes thaum rhuab (ntau tshaj 1011 ℃) los tsim cov roj fluoride (AlF3) roj, uas tuaj yeem tiv thaiv cov hlau molten thiab tiv thaiv oxidation, tab sis cov roj no muaj kev phom sij rau tib neeg lub cev.
2. Qhov saum npoo ntawm cov kab noj hniav ntub yog npog nrog cov hmoov cryolite, uas zoo tiv thaiv qhov tshwm sim ntawm subcutaneous pores.
Tom qab lub pouring, muaj ib tug cryolite yaj txheej ntawm cov hlau-pwm interface, uas muaj peev xwm yaj cov dej vapor txo cov tshuaj tiv thaiv ntawm lub interface, uas yuav txo tau lub hauv paus yuav tsum tau rau hydrogen evolution nyob rau hauv lub interface molten hlau txheej los ua npuas core;
Cov roj txhuas fluoride uas tsim los ntawm kev decomposition ntawm qis cryolite tuaj yeem tiv thaiv cov txheej txheem ferroelectric los ntawm cov tshuaj sib txawv ntawm cov txheej txheem interfacial, tiv thaiv cov txheej txheem interfacial ferromagnetic los ntawm absorbing hydrogen.
Cryolite lub cev muaj zog: sodium hexafluoroaluminate, molecular mis Na3AlF6, molecular hnyav yog 209.94, belongs rau complex, nws yog tsis yooj yim sua ua ob ntsev, Na + ion thiab [AlF6] 3- ion muaj nyob tom qab dissolution.
Non-toxic, dawb, off-dawb, daj hmoov los yog crystalline hais vim impurities, nws melting point yog 1025 ℃, bulk ntom yog 0.6 ~ 1.0g / L, tseeb ceev yog 2.95 ~ 3.05g / cm3, tshav kub tiam yog 225KJ ,
Qhov tshwj xeeb lub ntiajteb txawj nqus yog 2.75 ~ 3.00g / cm3, lub tshav kub ntawm fusion yog 107KJ, tsis muaj kob monoclinic crystals, zoo li yuav luag cubic, thiab cov khoom ntshiab yog xim tsis muaj xim.Nws feem ntau yog tawm-dawb, lub teeb daj, lub teeb liab, thiab dub vim yog impurities.
Nws feem ntau yog ib qho thaiv uas tsis haum rau kev faib.Nws cov luster yog pob tshab thiab moist, nws kab txaij yog dawb, thiab nws muaj lub iav luster.
Yooj yim nqus dej thiab noo noo, me ntsis soluble hauv dej, cov kua dej aqueous yog acidic, thiab nws tso tawm cov pa phem HF thaum nws ntsib sulfuric acid.
Feem ntau yog siv los ua ib qho flux rau aluminium smelting, tshuaj tua kab rau cov qoob loo, ua ib qho flux rau ceramic glazes, thiab ua tus neeg sawv cev opalescent;nws kuj yog siv los tsim cov iav opalescent, thiab nws kuj tseem siv tau los ua cov khoom siv electrolyte rau kev tsim cov aluminium alloys, hlau alloys, thiab boiling steels, thiab rau kev sib tsoo log, Cov khoom xyaw thiab lwm yam.
Pob: 25KG / hnab lossis raws li koj thov.
Cia: Khaws ntawm qhov chaw muaj cua, qhuav.
Executive Standard: International Standard.
