Khoom Description
Cov txheej txheem ntau lawm ntawmsilicon hlau 553Feem ntau suav nrog kev npaj cov khoom siv raw, hluav taws xob arc rauv smelting, refining thiab purification Raw khoom npaj: Kev tsim cov silicon hlau ua ntej yuav tsum tau npaj cov ntaub ntawv tsim nyog, thiab cov ntaub ntawv tseem ceeb yog quartz xuab zeb thiab coke ntawm lawv, quartz xuab zeb muaj ntau ntawm silica, thaum coke yog siv los ua tus neeg ua kom txo qis hauv cov txheej txheem ntawm kev npaj cov khoom siv raw, cov ntsiab lus ntawm impurity ntsiab yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov purity ntawm cov khoom kawg.

Cov khoom sib koom tes duab
1.Hluav taws xob arc rauv melting: Cov ntaub ntawv npaj tau muab ntxiv rau hauv hluav taws xob arc rauv thiab cov ntaub ntawv raw yog melted los ntawm qhov kub siab generated los ntawm hluav taws xob arcIn txheej txheem no, cov pa roj carbon nyob rau hauv lub coke undergoes ib tug txo cov tshuaj tiv thaiv nrog silica nyob rau hauv quartz xuab zeb. Txhawm rau tsim silicon hlau thiab carbon monoxide Thaum lub sij hawm melting txheej txheem, nws yog ib qho tsim nyog yuav tsum tswj qhov kub thiab qhov chaw nyob rau hauv lub cub tawg kom ntseeg tau tias cov kev vam meej ntawm cov tshuaj Refining thiab purification: cov silicon hlau tau los ntawm hluav taws xob arc rauv smelting kuj muaj qee yam impurity ntsiab, Yog li nws yuav tsum tau ua kom huv thiab huv hauv cov txheej txheem refining, los ntawm kev ntxiv cov additives tshwj xeeb, cov impurity ntsiab thiab additives yog chemically reacted los tsim cov tebchaw uas yooj yim rau kev cais, tom qab ntawd los ntawm qee yam kev ua haujlwm ntawm lub cev, xws li pom, distillation, thiab lwm yam., cov impurity ntsiab. tau muab cais tawm ntawm cov hlau silicon kom tau txais cov khoom siv siab purity silicon hlau Ua raws li kev kho mob: Cov hlau ua kom zoo thiab purified silicon hlau kuj yuav tsum tau ua tom qab ua tiav, xws li cua txias, crushing, tshuaj ntsuam xyuas, thiab lwm yam., kom tau raws li kev xav tau sib txawv ntawm tib lub sijhawm. , nruj zoo tswj cov txheej txheem ntau lawm kuj yuav tsum tau ua kom zoo thiab ruaj khov ntawm cov khoom. Los ntawm cov kauj ruam saum toj no, high-puritysilicon hlau 553tuaj yeem tsim los ua kom tau raws li qhov xav tau ntawm ntau yam kev lag luam.
