Hauv cov khoom siv pob zeb thiab cov khoom siv refractory, cov hmoov microsilica feem ntau yog siv los ua cov khoom siv los txhim kho kev ua haujlwm ntawm cov ntaub ntawv. Feem ntau, hauv pob zeb, nws tsuas yog ua haujlwm kom muaj zog, thaum nyob rau hauv cov ntaub ntawv refractory, nws tuaj yeem txhim kho lub zog refractory thiab kub refractory. Txawm li cas los xij, qee zaum microsilica hmoov tsis tuaj yeem siv ib leeg. Yog li, hauv cov xwm txheej sib txawv, dab tsi yog qhov zoo dua los siv microsilica hmoov ua ke?
1. Microsilica hmoov + High - dej txo tus neeg sawv cev
When microsilica powder is added to concrete, it fills the pores between cement particles, increases the density of the concrete, and has a strong segregation property, which leads to a large number of cracks in the concrete in the later stage. Tshwj xeeb tshaj yog raws li qhov ntau npaum ntawm microsilica hmoov nce, qhov tshwm sim no yuav hnyav dua. Yog li ntawd, nyob rau hauv ib txwm txoj kev, cov dej -binder ratio yog hloov los txo cov kab nrib pleb. Tab sis qhov no yuav inevitably hloov lwm yam kev ua tau zoo ntawm cov pob zeb. Yog li ntawd, thaum cov hmoov microsilica ntxiv, cov dej- txo tus neeg sawv cev kuj tseem ntxiv rau tib lub sijhawm, uas tuaj yeem txo cov kab nrib pleb tom qab ntawm cov pob zeb tsis hloov cov dej -binder ratio.
2. Microsilica hmoov + ya tshauv
Txawm hais tias microsilica hmoov muaj peev xwm los txhim kho kev ua tau zoo ntawm pob zeb, nws yog qhov nyuaj rau kev ua tiav cov txiaj ntsig xav tau thaum siv ib leeg. Txawm li cas los xij, ya tshauv, raws li lwm cov khoom sib xyaw ua ke, txawm hais tias nws tsis zoo li kev txhim kho lub zog ntawm pob zeb xws li microsilica hmoov, tuaj yeem txhim kho kev tsim kho ntawm pob zeb. Yog li ntawd, thaum ob qho tib si sib xyaw ua ke, kev ua tau zoo ntawm pob zeb tuaj yeem txhim kho.
3. Microsilica hmoov + ya tshauv thiab slag hmoov
Lub compounding ntawm microsilica hmoov, ya tshauv thiab slag hmoov yog tsuas yog los xyuas kom meej lub particle loj tis ntawm pob zeb, ua rau lub pores nyob rau hauv lub pob zeb tsawg thiab muaj pes tsawg leeg ntau ntom. Tshwj xeeb tshaj yog nyob rau hauv ultra- muaj zog ua vaj tse, ntau cov ntxhia pob zeb yuav tsum tau muab sib xyaw. Qhov loj me me ntawm cov hmoov slag feem ntau yog nyob ntawm 1 txog 100μm. Tom qab sib tsoo, qhov me me ntawm slag hmoov siv hauv pob zeb yog qis dua 5μm. Hauv qhov sib piv, 80% ntawm cov khoom ntawm microsilica hmoov yog qis dua 1μm, nrog rau qhov nruab nrab particle loj li ntawm 0.1μm mus rau 0.3 μm. Lawv tuaj yeem ua raws li qhov loj thiab me pores ntawm pob zeb. Txhawm rau ua kom lub zog ntawm ultra- muaj zog ua vaj tse siab dua thiab nws cov impermeability thiab lwm yam khoom zoo dua.
