Thawj qhov koj yuav tsum paub yog tias microsilica hmoov yog tsim rau cov khoom siv refractory; Raws li cov yam ntxwv sib txawv ntawm cov khoom siv raw cov ntaub ntawv, orthogonal tsim yog nqa tawm thiab cov txheej txheem sib txuam raug txheeb xyuas los ntawm kev sim sib piv. Feem ntau, unencrypted silica hmoov yog xaiv raws li cov khoom kub resistant. Nws muaj kev sib raug zoo nrog dej txo tus neeg sawv cev, ya tshauv, ntxhia hmoov thiab fiber ntau; vim qhov sib txawv filling phenomenon thaum siv.
Silica hmoov kuj muaj viscosity muaj zog, yog li qhov tsim ntawm kev ntxiv silica hmoov rau pob zeb rau deterioration yog 2 ~ 3cm siab dua li cov pob zeb zoo tib yam; Raws li qhov sib xyaw ua ke, thaum ua cov pob zeb ua kom muaj zog thiab txhaj tshuaj, qhov sib xyaw ntawm silica fume yog 6 ~ 6 npaug ntawm cov cement. 12% yog '; qhov sib tov ntim ntawm underwater engineering pob zeb yog me ntsis siab dua; Thaum silica fume yog siv los ua lub twj tso kua mis ntxiv, tag nrho cov tshuaj txo qis rau li 2%. Qhov piv txwv no tau lees paub los ntawm kev ntsuas piv. Kev sib xyaw ntawm silica fume, cement thiab aggregates yuav tsum tau ua raws li cov lus qhia nruj, thiab kev saib xyuas yuav tsum muaj zog.
Vim nws qhov tshwj xeeb zoo tshaj plaws, silica fume yuav tsum tau qhia tam sim tom qab pub mis. Microsilica fume tsis tuaj yeem muab ntxiv rau pob zeb. Los yog ntxiv cov hmoov microsilica, lub sij hawm sib tov yog 30-40 vib nas this ntev dua li cov pob zeb zoo tib yam, thiab homogeneity yog qhov zoo. Tsis muaj kev tshwj xeeb rau kev thauj mus los, ib yam li cov pob zeb zoo tib yam.
Tsis tas li ntawd, thaum siv cov hmoov silicon, txhua tus neeg yuav tsum coj mus rhaub thiab ua kom nws sib zog kom tsis txhob xau lossis ntau dhau kev co. Lub sijhawm vibration feem ntau yog 10-30 vib nas this; yuav tsum tau muab cov pob zeb txuas ntxiv los tiv thaiv cov kab mob khaub thuas thiab cov phom sij zais. Tsis txhob stubble ntau tshaj 100 feeb. Nws tseem yog ib qho tseem ceeb los tiv thaiv cov dej evaporation ntxov ntxov.
Yog li ntawd, tam sim ntawd tom qab nchuav cov hmoov silicon, npog nws nrog ib zaj duab xis, kis lub hnab thiab dej rau kev tu. Feem ntau, nws yog compressed microsilica hmoov rau kev siv, thiab koj tuaj yeem xaiv kev pub mis los yog pub mis tsis siv neeg. Vim nws cov khoom tshwj xeeb ultra-nplua, nws yuav tsum tau muab ntxiv tam sim tom qab muab cov khoom noj. Tom qab sib tov qhuav, ntxiv dej thiab lwm yam khoom xyaw.
