Silica fume (tseem hu ua micro silica fume) (lub npe scientific: "silica fume", Microsilica los yog Silica Fume), silica fume kuj hu ua silica fume.
Nws yog hais txog cov txheej txheem ntawm smelting industrial silicon thiab ferrosilicon nrog kub kub los ntawm kev lag luam hluav taws xob rauv, thiab cov pa luam yeeb thiab plua plav tawm nrog cov pa tawm yog sau los ntawm cov cuab yeej tshwj xeeb ntes.
Ua tiav. Hauv kev khiav tawm cov pa luam yeeb, cov ntsiab lus ntawm SiO2 suav txog li 90 feem pua ntawm cov pa luam yeeb tag nrho, qhov loj me me, thiab qhov nruab nrab particle loj.
Txog 0.3 μ m. Yog li nws yog hu ua silica fume.
Kev tshawb fawb ntawm silicon hmoov pib nyob rau hauv Scandinavian lub teb chaws, txawm hais tias tib neeg paub lub luag hauj lwm ntawm silicon hmoov nyob rau hauv 1950s.
Thiab kev tshawb fawb ua ntej, tab sis nws tau siv rau cov haujlwm ua haujlwm txij li xyoo 1970s. Ua ntej, Norway thiab Sweden thiab lwm lub tebchaws nyob hauv Hong Kong
Silica fume pob zeb yog ib feem siv nyob rau hauv wharf, North Sea roj teb thiab underground mine. Xyoo 1982, Norway
Silica fume pob zeb tau raug siv los ua kev tsim kho lub pas dej. Thaum xyoo 1980s, Canada tau tsim silica fume pob zeb hauv Quebec, thiab
Kev sim thiab kev tshawb fawb ntawm huab hwm coj silica fume pob zeb, sib tov 10000 cubic meters ntawm qib siab pob zeb. Xyoo 1983, silica fume tau siv hauv Tebchaws Meskas
Lub pob zeb tau kho lub Kacha Dam tseem nyob rau ntawm tus dej Orifuni nrog cov txiaj ntsig zoo. Lwm lub teb chaws hauv ntiaj teb kuj tau nce kev tshawb fawb thiab
Daim ntawv thov. Txawm li cas los xij, kev tshawb fawb keeb kwm ntawm silica fume hauv Suav teb tsis ntev, tsuas yog ntau tshaj 10 xyoo
Lub Kaum Ob Hlis Ntuj Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm ntawm Dej thiab Hluav Taws Xob tau sim silica fume ua vaj tse thawj zaug hauv Yuzixi II Hydropower Chaw nres tsheb hauv Sichuan, thiab ntxiv silicon rau hauv lub zog ua vaj tse.
Hmoov 3 feem pua ~7 feem pua los txhim kho lub zog thaum ntxov, ua kom lub zog ntawm kev ua haujlwm, thiab ua tiav cov txiaj ntsig xav tau. Tsis tas li ntawd, tshuaj tsuag hauv qhov taub taub hau
715 feem pua silica fume yog tov nyob rau hauv cov pob zeb kom txo tau cov rebound ntawm cov pob zeb. South Academy of Sciences tso cov pob zeb hauv Dahuofang Reservoir Project thiab Longyang Gorge
Silica fume qhob yog siv rau hauv cov qauv dej, Gezhouba sluice qhov rooj kho thiab lwm yam dej num uas muaj txiaj ntsig zoo
Lub durability ntawm pob zeb thiab silica fume cement thiab algae grouting cov ntaub ntawv yog kawm, thiab consolidation grouting yog nqa tawm rau lub hauv paus ntawm Ertan Hydropower Station
Nyob rau hauv Tuam Tshoj, silica fume yog siv nyob rau hauv lub Panjia Dam overflow nto kho qhov project, Ankang thiab Sichuan Qiuda Hydropower chaw nres tsheb diversion spillway qhov kho qhov project, thiab lwm yam
Pob zeb thiab silica fume cement grouting. Tag nrho cov no qhia tias silica fume pob zeb, raws li kev ua haujlwm siab ua vaj tse, yuav tsum
Kev siv tau dhau los ua qhov tseem ceeb, yog li kev tshawb fawb ntawm nws qhov kev ua tau zoo, tshwj xeeb tshaj yog nws lub zog thiab kav ntev, kuj tau txais kev saib xyuas ntau.
