Microsilica Fume yog dab tsi?

Microsilica fume, tseem hu ua silica fume lossis microsilica fume, yog cov khoom tsim los ntawm kev sau thiab ua cov pa luam yeeb thiab plua plav uas tawm nrog cov pa pa thaum lub sij hawm kub kub smelting ntawm industrial silicon thiab ferrosilicon nyob rau hauv industrial hluav taws xob furnaces. Hauv cov pa luam yeeb no, SiO2 cov ntsiab lus suav txog li 90% ntawm tag nrho cov pa luam yeeb. Cov particle loj me me heev, thiab qhov nruab nrab particle loj yog yuav luag nyob rau theem nanometer, li no lub npe microsilica hmoov. Cov khoom tseem ceeb ntawm microsilica hmoov yog SiO2, uas yog cov khoom tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis muaj kuab lom tsis muaj kuab lom tsis muaj cov khoom siv hlau ua haujlwm. Nws muaj qhov kub thiab txias tsis kam, acid thiab alkali corrosion kuj, thermal conductivity, siab rwb thaiv tsev, tsis tshua muaj expansion thiab tshuaj lom neeg zog. Cov khoom zoo xws li stability thiab siab hardness. Kev tsim cov hmoov microsilica belongs rau cov khoom lag luam uas tsis yog xim hlau hauv kev lag luam thiab yog dav siv los ua cov khoom siv raw thiab cov khoom siv hauv kev lag luam ib txwm muaj xws li cov khoom siv hauv tsev, metallurgy, tsheb, tshuaj, thiab lub teeb muaj tshuab. Nws tseem yog kev txhawb nqa rau kev lag luam high-tech xws li cov ntaub ntawv hluav taws xob, lub zog tshiab, thiab cov khoom siv tshiab. Khoom siv.
