Kev tshawb Silicon
Aug 30, 2019
Kev tshawb fawb ntawm cov kab mob silica fume tau pib hauv Scandinavia. Txawm hais tias muaj qee qhov kev nkag siab thiab kev tshawb fawb ua ntej txog lub luag haujlwm ntawm silica fume hauv xyoo 1950, nws tau thov hauv kev siv tswv yim tsim txij li xyoo 1970. Ua ntej, Norway thiab Qee lub tebchaws xws li Sweden tau siv cov pob zeb ua kua silica fume hauv cov chaw nres nkoj, Beihai cov roj av thiab cov av hauv av. Xyoo 1982, Norway lees saws cov tshuab ua kua silicon hmoov pob zeb txhaws ntawm lub pas dej Funovs. Thaum xyoo 1980s, Canada tau tsim hauv Quebec. Silicon hmoov pob zeb ua pob zeb, thiab kev sim tshawb fawb txog qhov loj-ntau qhov tseeb silicon hmoov ua vaj tse, sib xyaw ua ke 10,000 cubic meters ntawm cov qib siab ua vaj tse. Xyoo 1983, Asmeskas tau siv cov tshuaj silicon hmoov pob zeb los kho lub pas dej Kacha Dam tseem nyob rau ntawm tus dej Orifny, muaj cov txiaj ntsig zoo. Lwm lub tebchaws hauv ntiaj teb kuj tau tshawb nrhiav thiab thov nyiaj. Txawm li cas los xij, Tuam Tshoj muaj keeb kwm ntev ntawm kev tshawb fawb ntawm silicon hmoov. Tsuas yog ntau tshaj 10 xyoo, xyoo 1985, Lub Tuam Txhab ntawm Hydrology ntawm Sab Hnub Tuaj Lub Tuam Txhab ntawm Kev Kho Hluav Taws Xob thiab Kaum Tshav Hluav Taws Xob Hluav Taws Xob ntawm Ministry of Dej thiab Hluav Taws Xob ua ntej kuaj silica fume qhob hauv Yuzixi theem nrab fais fab chaw nres tsheb hauv Sichuan. Cov pob zeb ua ke yog xyaw nrog silicon hmoov li 3% mus rau 7% txhawm rau txhim kho thaum ntxov ua kom muaj zog thiab ua kom nrawm nrawm nrawm los ua kom tiav cov txiaj ntsig. Tsis tas li ntawd, nyob rau hauv rab phom ntawm qhov sib tw sib txawv ntawm lub qhov siab, silica hmoov yog 715% kom txo qhov rov cuam tshuam ntawm pob zeb. Silica fume pob zeb ua tiav siv hauv Dahuofang Qhov Chaw Ua Haujlwm Kev Tiv Thaiv Kev Nyab Xeeb, Longyangxia Dej Ua Vaj Tsev thiab Kev Kho Vaj Tsev Qoj Hauv Tebchaws Gezhouba Lub koom haum ntawm Kev Tshawb Fawb Txog Kev Tshawb Fawb ua kom lub sijhawm siv dej ntawm silica fume concrete thiab silt cement algae grouting cov khoom. Qee qhov kev tshawb nrhiav tau tau coj los ua qhov kev sib koom ua ke ntawm Ertan Hydropower Station. Lub Pas Dej Panjia Lub Tuam Txhab dhau los tsim kho lub chaw, Ankang thiab Sichuan Qiuda hydropower chaw nres tsheb ntau qhov kev kho thiab lwm qhov dej num siv silicon hmoov pob zeb ua, silicon hmoov MAAs grouting. Tag nrho cov no qhia tias daim ntawv thov ntawm silica fume pob zeb ua kev ua tau zoo siab rau kev ua vaj tse hauv engineering tau dhau los ua qhov tseem ceeb dua, yog li kev tshawb fawb ntawm nws qhov kev ua tau zoo, tshwj xeeb nws lub zog thiab kav ntev, kuj tau txais ntau lub siab.
