Silicon yog cov khoom tsis yog xim hlau, grey-xiav, nws yog xim hlau, tawv thiab nkig, cov ntsiab lus ntawm silicon yog li 26% ntawm cov khoom siv hauv ntiaj teb, cov npe nrov npe ntawm silicon hlau thaiv feem ntau yog raws li cov ntsiab lus ntawm hlau, txhuas, calcium peb thawj impurities muaj nyob rau hauv silicon hlau yog cais. Raws li cov ntsiab lus ntawm pawg hlau, txhuas, calcium hauv silicon hlau, silicon hlau tuaj yeem muab faib ua 553, 441, 411, 421, 3303, 3305, 2202, 1101 thiab lwm qib.
Silicon hlau thaiv kev siv:
(1) silicone, silicone resin, methyl silicone roj thiab lwm yam silicon tooj liab ntau lawm thiab raug. Silicone toughness, tshav kub-resistant, siv los ua cov khoom siv kho mob thiab kub-kub gaskets. Organic silicone resin yog siv los tsim kev tsim peb cov xim pleev xim, kub kub resistant xim thiab lwm yam. Methyl silicone roj yog roj-soluble tshuaj, viscosity los ntawm ambient kub tsis muaj teeb meem. Nws yog siv nyob rau hauv zus tau tej cov lubricants, polishing agents, kua torsion caij nplooj ntoos hlav, electrolytic nruab nrab kua, thiab lwm yam, kuj yuav ua tau rau hauv ib tug tsis muaj kob pob tshab kua, raws li ib tug tshuaj tsuag rau saum npoo ntawm lub tsev.
(2) Kev tsim khoom thiab tsim cov khoom siv hluav taws xob siab purity semiconductor. Feem ntau ntawm cov khoom siv hluav taws xob tam sim no yog tsim los ntawm cov hlau purity silicon hlau, thiab cov hlau purity silicon hlau yog siv los ua cov khoom tseem ceeb rau cov xov hlau fiber ntau. Silicon hlau tau dhau los ua kev lag luam hauv cov ntaub ntawv hnub nyoog.
(3) Ua aluminium alloy. Aluminium alloy profile yog silicon alloy uas muaj ntau cov xim hlau silicon, silicon aluminium alloy yog ib qho muaj zog deoxidizer. Hloov cov ntshiab txhuas hauv cov txheej txheem steelmaking tuaj yeem txhim kho qhov kev siv tus nqi deoxidant, ntxuav thiab kho cov kua hlau, thiab txhim kho cov hlau zoo. Aluminium muaj qhov ntom ntom, qis coefficient ntawm linear expansion, zoo forging thiab hnav tsis kam. Aluminium alloy castings forged nrog txhuas muaj kev cuam tshuam zoo thiab kev cog lus zoo, uas tuaj yeem ua rau muaj kev pab cuam lub neej. Nws yog feem ntau siv nyob rau hauv zus tau tej cov aerospace tsheb thiab automotive qhov chaw. Silicon-tooj liab-nickel alloys muaj qhov zoo weldability thiab tsis yooj yim ua rau hluav taws kub thaum muaj kev sib tsoo. Nws yog hluav taws kub resistant thiab haum rau cia tank.
Silicon hlau thaiv qhov tseem ceeb tag nrho cov txheej txheem yuav tsum tau sib tov ntau, uas yog raws li cov hauv paus ntsiab lus ntawm compressed roj. Lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov tshuaj lom neeg hauv cov khoom siv raw cov tshuaj tiv thaiv kinetic qauv tus qauv, ua kom cov slagging tus nqi, tshem tawm cov av thaum ntxov, txo cov cua sov thiab kev sib txuas ntawm silicon. Vim tias muaj cov hlau silicon tsawg heev hauv nws cov khoom siv ntuj tsim, feem ntau ntawm cov hlau silicon hauv lub neej txhua hnub yog tsim los ntawm tib neeg kev ua haujlwm.
