Silicon hlau 441 nrog kev ua tau zoo

Silicon hlau 441 yog ib qho kev lag luam qib hlau silicon, feem ntau yog siv rau hauv kev lag luam alloy additives, semiconductor cov ntaub ntawv, thiab lwm yam. Nws yog grey, nws yog xim hlau xim, tawv thiab nkig. Cov ntsiab lus silicon (Si) yog qhov siab heev, feem ntau ntau dua 98%, thiab muaj qee yam ntawm cov impurities, xws li hlau (Fe) txog 0.4%, txhuas (Al) txog 0 .4%, calcium (Ca) txog 0.1%, thiab lwm yam. Silicon hlau muab faib ua ntau qib raws li nws cov ntsiab lus impurity, xws li 553, 441, 3303, 2202, thiab lwm yam. 441 yog ib qho ntawm cov qib. Silicon hlau yog cov khoom tsis yog xim hlau, tab sis nthuav tawm cov khoom zoo li hlau nyob rau hauv qee yam mob. Nws yooj yim reacts nrog cov ntsiab lus xws li oxygen thiab nitrogen los tsim cov sib txuas sib txuas.

Kev tsim khoom ntawm silicon hlau 441 feem ntau yog ua los ntawm silica (lub ntsiab lus tseem ceeb yog silicon dioxide) ua raw khoom los ntawm kev txo cov tshuaj tiv thaiv. Thaum lub sij hawm tsim khoom, cov khoom siv raw yuav tsum tau crushed, tshuaj xyuas, txo, ua kom zoo thiab lwm cov kauj ruam kom tau txais cov khoom siv hlau silicon uas ua tau raws li qhov yuav tsum tau ua. Nyob rau tib lub sijhawm, cov khoom tiav kuj yuav tsum tau soj ntsuam nruj me ntsis thiab tswj tau zoo kom ntseeg tau tias lawv cov kev ua haujlwm ruaj khov thiab txhim khu kev qha.

Kev siv lub ntsiab ntawm cov xim hlau silicon 441 yog qhov dav heev, tshwj xeeb tshaj yog ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. Hlau silicon 441 yog ib qho tseem ceeb raw khoom rau kev tsim aluminium alloys, silicon-aluminium alloys thiab ferrosilicon alloys. Los ntawm kev ntxiv cov xim hlau silicon, cov khoom siv kho tshuab ntawm cov hlau tuaj yeem txhim kho tau zoo, xws li nce hardness, lub zog thiab hnav tsis kam. Hauv kev tsim cov aluminium alloy, qhov sib ntxiv ntawm cov xim hlau silicon 441 tuaj yeem ua kom zoo dua qhov kev ua haujlwm casting thiab kev ua haujlwm ntawm cov hlau, thaum txhim kho nws cov corrosion kuj thiab kub ua hauj. Hlau silicon 441 tuaj yeem siv los ua cov khoom siv raw rau cov organic silicon tebchaw hauv kev lag luam tshuaj, xws li roj silicone, silicone roj hmab thiab silicone resin. Cov organic silicon tebchaw muaj qhov kub thiab txias tsis kam, tsis kub tsis kam, oxidation tsis kam, ozone tsis kam, hluav taws xob tiv thaiv thiab hluav taws xob rwb thaiv tsev, thiab tau dav siv hauv kev sib khi, lubrication, kev sib txuas, demoulding thiab kho qhov chaw.

Silicon hlau 441 tuaj yeem siv los tsim cov khoom siv refractory xws li refractory cib, refractory coatings thiab refractory pob zeb.
Cov ntaub ntawv refractory no muaj siab refractoriness thiab thermal shock tsis kam, thiab tuaj yeem tiv taus thermal shock thiab tshuaj yaig ntawm qhov kub thiab txias, yog li lawv tau siv dav hauv cov txheej txheem ntawm cov khoom siv hluav taws xob xws li metallurgy, iav thiab ceramics.
