Ob leegya tshauvthiabmicro silica (silica fume)yog cov ntxhia admixtures siv hauv pob zeb thiab cov khoom siv hauv tsev, tab sis lawv cov peev txheej, cov khoom siv thiab kev siv sib txawv.
Qhov chaw
Fly tshauv:Nws yog cov hmoov tshauv zoo uas tsim los tom qab kev sib xyaw ntawm cov thee hauv cov hluav taws xob hluav taws xob hluav taws xob thiab yog cov khoom lag luam. Nws yog cov yoov tshauv uas tsim thaum lub sij hawm combustion ntawm thee thiab yog sau los ntawm cov khoom siv tshem tawm plua plav.
Microsilica (silica fume):Nws yog cov hmoov av zoo uas tsim tawm thaum lub sij hawm tsim cov hlau silicon, feem ntau yog los ntawm cov pa roj plua plav tshem tawm ntawm lub cub hluav taws xob hauv kev tsim cov silicon alloys.
Kev sib xyaw thiab cov khoom
Fly tshauv:
Tshuaj muaj pes tsawg leeg: Cov khoom tseem ceeb muaj xws li silicon dioxide (SiO₂), aluminium dioxide (Al₂O₃), calcium dioxide (CaO), thiab lwm yam.
Particle loj: Cov particle loj ntawm yoov tshauv feem ntau loj dua thiab cov hais kuj coarse.
Lub cev muaj zog: ya tshauv feem ntau yog grey los yog dub thiab muaj qee yam ntawm hygroscopicity.
Microsilica (silica fume):
Tshuaj muaj pes tsawg leeg: Cov khoom tseem ceeb yog silicon dioxide (SiO₂), nrog rau siab purity.
Particle loj: Cov particle loj me me, feem ntau nyob rau hauv micron theem, txawm tias me dua li cov cement.
Lub cev muaj zog: Microsilica fume feem ntau yog grey los yog tsaus grey, thiab cov particle loj me me, uas muab rau nws qhov chaw siab heev.
Muaj nuj nqi thiab kev siv
Fly tshauv:
Kev ua tau zoo ntawm pob zeb: Raws li cov khoom siv ntxhia, ya tshauv tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb, ua kom muaj zog, thiab txo cov cement noj.
Cov txiaj ntsig ib puag ncig: Siv cov hmoov tshauv ya raws li cov khoom sib xyaw pab txo cov khoom pov tseg thiab txuag cov ntaub ntawv raw.
Microsilica fume (silica fume):
Kev ua tau zoo ntawm pob zeb: Lub siab reactivity ntawm microsilica fume ua rau nws txhim kho lub zog, ntom thiab hnav tsis kam ntawm cov pob zeb, thiab feem ntau yog siv hauv cov pob zeb muaj zog, pob zeb tshwj xeeb, thiab lwm yam.
Durability: Microsilica fume pab txo cov porosity ntawm pob zeb thiab txhim kho nws cov tsis kam mus rau tshuaj yaig.
Cov chaw thov
Fly tshauv:Siv dav hauv kev ua vaj tse zoo tib yam, kev tsim vaj tsev, sau, thiab lwm yam.
Microsilica fume (silica fume):Feem ntau yog siv rau hauv cov ntawv thov nrog kev ua haujlwm siab xws li cov pob zeb ua haujlwm siab, cov pob zeb muaj zog, thiab cov khoom siv refractory.
Piv txwv li, txawm hais tias ya tshauv thiab microsilica fume yog ob qho tib si pob zeb sib xyaw, vim lawv qhov chaw sib txawv, cov khoom siv thiab kev ua haujlwm, lawv muaj qhov zoo sib txawv thiab siv hauv cov ntawv thov tshwj xeeb.
