Cov kev siv tseem ceeb ntawm microsilica hmoov
Micro-silica hmoov, tseem hu ua silica tshauv, yog cov plua plav rov qab los ntawm cov pa roj ntawm cov hlau smelting xws li silicon hlau lossis ferrosilicon. Qhov nruab nrab me me ntawm micro-silica hmoov yog 0.2um, thiab thaj chaw tshwj xeeb yog 15000-25000 m2 / kg. Nws cov khoom tseem ceeb yog silicon dioxide, nrog 85 feem pua -95 feem pua cov ntsiab lus, thiab cov impurity Cheebtsam yog sodium oxide, sodium oxide, calcium oxide, hlau oxide, txhuas oxide thiab lwm yam hlau oxides thiab ib tug me me ntawm singlet carbon thiab silicon. , thiab lwm yam Txij li silica hauv microsilica hmoov yog cov khoom siv amorphous nrog kev ua haujlwm siab, cov khoom zoo, thaj chaw loj tshwj xeeb thiab cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, nws tau siv los suav tias yog cov khoom siv pov tseg, tab sis tam sim no nws tau nce ntxiv raws li qhov muaj txiaj ntsig zoo. , ib yam ntawm cov hmoov superfine tsis crushing ua thiab pheej yig, uas tuaj yeem siv dav hauv cov pob zeb, cov khoom siv refractory, cov ntaub ntawv phab ntsa, cov khoom siv cement, mortar, flooring, tshuaj lom neeg kev lag luam thiab lwm yam tseem ceeb siv hauv cov haujlwm tshwj xeeb.
Micro-silica hmoov yog qhia tshwj xeeb hauv cov hauv qab no ntawm daim ntawv thov.
1, Micro-silica hmoov yog siv los ua ib qho ntxiv hauv cov ntaub ntawv refractory
Tuam Tshoj yog lub ntiaj teb cov neeg siv khoom loj tshaj plaws ntawm refractories, thiab kev siv thev naus laus zis ntawm Sanyuan microsilica hmoov nyob rau hauv refractories yog tus paub tab, tshwj xeeb tshaj yog zoo microsilica hmoov muaj cov yam ntxwv ntawm fluidity siab, tsis tshua muaj dej cia, siab density thiab siab zog. Nws yog tsuas yog siv los ua kev ua haujlwm siab refractory castables, prefabricated qhov chaw, cov ntaub ntawv ladle, breathable bricks, nws tus kheej ntws refractory castables thiab qhuav thiab ntub cov ntaub ntawv. Raws li oxide bonded silicon carbide khoom, kub kub hom calcium silicate lub teeb rwb thaiv tsev ntaub ntawv, corundum mullite laub phaj rau electromagnetic kilns, kub hnav resistant cov ntaub ntawv thiab cov khoom, corundum thiab ceramic khoom, thiab lwm yam.
2, micro-silica hmoov rau pob zeb ua kom muaj zog ntxiv
Kev lag luam pob zeb yog qhov kev tshawb fawb ntxov tshaj plaws nyob rau hauv txawv teb chaws micro-silica hmoov kev siv dav dav, kev ua tau zoo tshaj plaws, kev siv dav tshaj plaws hauv kev lag luam. Raws li micro-silica hmoov muaj cov khoom zoo, thaj chaw loj tshwj xeeb, siab purity ntawm SiO2, volcanic tshauv thiab lwm yam ntxwv ntawm lub cev thiab tshuaj lom neeg, micro-silica hmoov ua cov khoom sib xyaw ntxiv rau cov pob zeb tuaj yeem txhim kho kev ua tau zoo ntawm pob zeb hauv ntau yam, xws li txhim kho cov khoom adhesion ntawm cov yas pob zeb thiab cohesion, txo tus nqi ntawm rebound, nce lub thickness ntawm shotcrete ib zaug, txo lub sij hawm tsim kho, txuag tus nqi ntawm qhov project.
Nyob rau hauv lub tshav pob ntawm kev ua tau zoo zoo tib yam thiab ultra-high-kev ua tau zoo active hmoov pob zeb, micro-silica hmoov raws li ib tug admixture los tsim high-strength pob zeb, nws lub zog qib tuaj yeem ncav cuag ntau pua MPa lossis ntau dua. Piv txwv li: RPC pob zeb, HPC pob zeb, yeeb nkab pob zeb, thiab lwm yam.
3, Micro-silica hmoov yog cov khoom sib xyaw ntawm cov cement
Xyoo 1982, Lafarge Cement Company ntawm Fabkis siv micro-silica hmoov tov nrog Portland clinker los tsim cov cement sib xyaw rau hauv kev ua lag luam. Feem ntau, micro-silica hmoov ua rau hauv spheres yog hauv av ua ke nrog clinker los tsim cov cement sib xyaw uas muaj txog 6 feem pua ntawm cov hmoov micro-silica. Tam sim no, qee qhov tshwj xeeb ntawm cov cement hauv tsev, tau dav ntxiv micro-silica hmoov sib xyaw cov cement lossis cov cement tshwj xeeb.
4, Micro-silica hmoov yog cov khoom tseem ceeb ntawm sab nrauv phab ntsa rwb thaiv tsev STP hollow rwb thaiv tsev board
Siv cov yam ntxwv ntawm qhov ceev qis, tsawg noo noo kom qhuav, zoo nkauj ntawm cov khoom pib (thiab lwm yam khoom siv silica, thiab lwm yam kev sib tw ntawm cov duab loj ntawm cov khoom phab ntsa, airtight thiab compressed, thiab kos rau hauv lub hollow. Silica fume li inorganic non-metallic cov ntaub ntawv, thermal conductivity tsawg heev, ua los ntawm hollow rwb thaiv tsev board muaj ib tug sib dua, ntau zog-txuag rwb thaiv tsev yam ntxwv.
5, Micro-silica hmoov yog ib qho tshuaj ntxiv rau mortar, siab grout, grouting khoom, thiab lwm yam.
Phab ntsa zog txuag, rwb thaiv tsev, tiv thaiv hluav taws yog kev lag luam hotspots nyob rau hauv xyoo tas los no, yog li ntawd, rwb thaiv tsev mortar, foamed qhob panels thiab aerated qhob yog sawv tawm. Silica fume raws li kev txhim kho lub zog, fluidity yam kuj tshwm sim hauv cov khoom siv no.
Nyob rau tib lub sijhawm, nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm high-speed railway technology thiab kev tsim kho kev xav tau, los ntawm kev txhim kho cov tshuab grout, kev siv cov cement ntxiv ya tshauv ntxiv silica fume ntxiv rau cellulose ntxiv rau defoamer ntxiv rau cov dej txo tus neeg sawv cev ntxiv rau kev nthuav dav. tus neeg sawv cev, thiab lwm yam., tsim los rau hauv tus kheej super ntws, siab zog, ntom pore siab grout. Cov thev naus laus zis no tau dhau los ua neeg paub tab thiab tau siv dav hauv kev loj, txuas hniav thiab kev tsheb ciav hlau ceev.
