Silicon slag, ib tug by-product ntawm silicon hlau thiab ferrosilicon ntau lawm, tau lug siv nyob rau hauv ntau yam industries, xws li steel-ua, cement ntau lawm, thiab chiv. Nws yog cov khoom siv pheej yig thiab muaj txiaj ntsig zoo uas tuaj yeem txhim kho kev ua tau zoo thiab zoo ntawm cov khoom no.
Hauv kev lag luam steel, silicon slag yog siv los ua deoxidizer thiab desulfurizer tus neeg sawv cev. Ntxiv ib qho me me ntawm silicon slag rau hauv cov hlau molten tuaj yeem tshem tawm cov impurities thiab txhim kho qhov zoo ntawm cov khoom kawg. Tsis tas li ntawd, silicon slag kuj tuaj yeem ua rau lub zog tensile thiab elongation ntawm cov hlau, ua rau nws ruaj khov thiab txhim khu kev qha.
Hauv kev lag luam cement ntau lawm, silicon slag yog siv los ua lwm txoj hauv kev limestone thiab av nplaum. Nws tuaj yeem hloov tau txog li 30% ntawm cov khoom siv raw siv hauv cov txheej txheem tsim cov cement, txo kev siv hluav taws xob thiab cov pa hluav taws xob hauv tsev cog khoom. Ntxiv mus, silicon slag tuaj yeem txhim kho kev ua tau zoo ntawm pob zeb los ntawm kev txhim kho nws lub zog compressive thiab txo nws cov permeability.
Hauv kev lag luam chiv ntau lawm, silicon slag yog siv los ua silicon fertilizer. Nws tuaj yeem muab cov nroj tsuag nrog cov khoom noj tseem ceeb silicon, uas muaj txiaj ntsig zoo rau lawv txoj kev loj hlob thiab kev loj hlob. Tsis tas li ntawd, silicon slag tuaj yeem ua rau muaj kev tiv thaiv ntawm cov nroj tsuag mus rau ib puag ncig kev ntxhov siab, xws li dej qhuav thiab kab mob.
Zuag qhia tag nrho, kev siv cov silicon slag muaj qhov zoo ntawm ntau yam kev lag luam. Nws tuaj yeem tsis tsuas yog txhim kho cov khoom zoo tab sis kuj txo cov nqi tsim khoom thiab kev cuam tshuam ib puag ncig. Yog li ntawd, cov kws tshawb fawb thiab kev lag luam tab tom tshawb nrhiav ntau txoj hauv kev tshiab los siv thiab siv silicon slag los tsim lub neej yav tom ntej.
