Tib yam siv
Kev lag luam metallurgical li deoxidizer
Ob leeg Silicon hlau 441 thiab 553 tuaj yeem siv los ua deoxidizers hauv steelmaking thiab casting txheej txheem. Vim tias silicon muaj kev sib raug zoo nrog cov pa oxygen, lawv tuaj yeem hnov mob nrog oxygen hauv cov hlau los yog hlau los tsim cov silicon dioxide. Piv txwv li, cov tshuaj tiv thaiv mis yog tias cov khoom tsim tawm silicon dioxide yuav ntab rau ntawm cov kua dej hauv daim ntawv ntawm slag, yog li txo cov pa oxygen hauv cov hlau molten, txo qhov tsis xws luag xws li pores thiab slag inclusions, thiab txhim kho cov hlau zoo. cov ntaub ntawv.
Kev lag luam metallurgical ua tus neeg sawv cev alloying
Ob leeg tuaj yeem siv los ua cov neeg ua haujlwm alloying hauv cov hlau thiab casting kev lag luam. Lawv tuaj yeem sib xyaw cov ntsiab lus silicon rau hauv cov hlau matrix los txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov hlau. Piv txwv li, thaum ua silicon steel, ntxiv Silicon hlau 441 lossis 553 tuaj yeem ua rau cov hlau nplaum permeability ntawm cov hlau thiab txhim kho nws cov khoom siv hluav taws xob; Thaum casting aluminium alloys, silicon cov ntsiab lus tuaj yeem kho cov nplej thiab txhim kho lub zog thiab tawv ntawm aluminium alloys.
Kev siv sib txawv
Kev lag luam hluav taws xob
Silicon hlau 441: Vim nws cov ntsiab lus impurity tsawg, tshwj xeeb tshaj yog kev tswj nruj ntawm impurities xws li hlau, txhuas, thiab calcium, silicon hlau 441 yog qhov tsim nyog rau kev lag luam hluav taws xob. Nyob rau hauv cov txheej txheem tsim khoom semiconductor, high-purity silicon hlau 441 yog ib qho tseem ceeb raw khoom. Tom qab cov txheej txheem ntawm kev ua kom huv si, xws li lub cev vapor deposition, tshuaj vapor deposition, thiab lwm yam, nws tuaj yeem ua rau ib leeg siv lead ua silicon rau kev tsim cov khoom siv hluav taws xob siab xws li kev sib xyaw ua ke thiab cov chips. Cov khoom siv hluav taws xob no muaj qhov xav tau siab heev rau silicon purity, vim tias impurities tuaj yeem cuam tshuam rau cov khoom siv hluav taws xob thiab kev ruaj ntseg ntawm cov khoom.
Silicon hlau 553: Vim nws cov ntsiab lus siab impurity, nws daim ntawv thov hauv kev lag luam hluav taws xob yog txwv. Txawm li cas los xij, hauv kev tsim khoom ntawm qee cov khoom siv hluav taws xob uas tsis tas yuav muaj qhov tshwj xeeb ntawm silicon purity, xws li qee cov khoom siv hluav taws xob ntim khoom lossis kev tsim cov khoom siv hluav taws xob rau qee cov khoom siv hluav taws xob qis, silicon hlau 553 tuaj yeem siv los ua cov khoom siv raw, thiab nws cov nqi kuj tsawg, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov khoom no rau qee yam.
Kev lag luam tshuaj
Silicon hlau 441: Nws muaj ntau qhov zoo hauv kev tsim cov purity organosilicon compounds. Piv txwv li, thaum tsim ib co high-end silicone roj, silicone roj hmab los yog silicone resins, high-purity silicon qhov chaw yog yuav tsum tau los xyuas kom meej cov kev ua tau zoo thiab zoo ntawm cov khoom. Silicon hlau 441 tuaj yeem hnov mob nrog cov tebchaw xws li organochlorosilanes, thiab tom qab ua cov txheej txheem polymerization thiab hloov kho, tsim cov khoom zoo silicone. Cov khoom no feem ntau siv rau hauv aerospace, high-end electronics thiab lwm yam kev lag luam uas yuav tsum tau nruj me ntsis rau cov khoom ua tau zoo.
Silicon hlau 553: Feem ntau yog siv los tsim qee cov khoom siv tshuaj uas tsis tas yuav muaj kev purity tshwj xeeb. Piv txwv li, hauv kev tsim cov khoom siv hauv tsev zoo tib yam, cov khoom siv silicone roj hmab, thiab lwm yam, Silicon hlau 553 tuaj yeem siv los ua cov khoom siv raw. Nws tuaj yeem hnov mob nrog lwm cov khoom siv tshuaj lom neeg los tsim cov tshuaj silicone intermediates, thiab tom qab ntawd ua tiav rau hauv ntau yam khoom siv tshuaj lom neeg kom tau raws li qhov xav tau ntawm qee qhov kev lag luam niaj hnub thiab pej xeem.
