Silicon hlauyog cov khoom siv tseem ceeb rau ob qhov kev lag luam loj: aluminium alloy ntau lawm thiab organosilicon synthesis. Peb qhov kev lag luam feem ntau yog qib kev lag luamSilicon hlau 553, Silicon hlau 441thiabSilicon hlau 3303. Ntau tus neeg yuav khoom tsuas yog xaiv cov qib raws li tus nqi tag yam tsis muaj kev nkag siab txog impurity kam rau ua ntawm lawv tus kheej cov txheej txheem ntau lawm.
Nyob rau hauv aluminium smelting, ntau hlau thiab calcium tuaj yeem degrade casting kev ua tau zoo thiab nce seem seem. Rau organosilicon monomer ntau lawm, taug qab hnyav hlau impurities yuav tshuaj lom tooj liab raws li catalysts, qis dua monomer tawm los thiab tsim ntau yam khoom uas tsis xav tau. Kev siv cov qib silicon hlau tsis raug yuav ua rau cov khoom poob qis txawm tias cov khoom siv raw khoom zoo li kev sib tw.
Kev ua tau zoo sib txawv ntawm peb qib
553 yog qib purity qis tshaj ntawm peb. Nws nta ntau dua hlau, aluminium thiab calcium cov ntsiab lus. Tus nqi tsim khoom nyob ntawm tus nqi qis. Nws impurity kam rau ua yog txwv. Cov ntsiab lus calcium siab thiab hnyav hlau txwv nws txoj kev siv hauv cov tshuaj rhiab heev.
441 yog cov hom phiaj siv dav tshaj plaws. Nws sib npaug purity thiab ntau lawm tus nqi. Hlau thiab txhuas yog tswj kom 0.40% siab tshaj plaws, thiab calcium yog txwv rau 0.10%. Nws haum rau feem ntau cov txheej txheem tsim khoom thiab ua haujlwm rau ob qho tib si txhuas thiab organosilicon kev lag luam. Nws yog qib workhorse rau loj ntim manufacturing.
3303 yog siab purity silicon hlau. Hlau thiab txhuas yog capped ntawm 0.30%, thiab calcium yog nruj me ntsis tswj hauv qab 0.03%. Boron, phosphorus thiab cov hlau hnyav hnyav kuj tseem khaws cia ntawm qib qis dua. Cov khoom xa tuaj ruaj khov rau cov kab ntau lawm, tab sis cov khoom siv raw khoom yog siab dua 553 thiab 441.
Basic Qib txhais thiab tshuaj Specification
Txoj cai plaub tus lej npe rau cov hlau silicon sawv cev rau cov ntsiab lus siab tshaj plaws ntawm hlau, txhuas thiab calcium nyob rau hauv ib ntus. Piv txwv li Si 553 txhais tau tias Fe Tsawg dua lossis sib npaug rau 0.50%, Al Less dua lossis sib npaug li 0.50%, Ca Less dua lossis sib npaug li 0.30%. Peb lub ntsiab lus no yog cov khoom tswj hwm thawj. Rau cov ntawv thov siab kawg, cov neeg yuav khoom kuj yuav tsum tau saib xyuas boron, phosphorus thiab taug qab cov hlau hnyav xws li npib tsib xee, tooj liab thiab titanium.
