Dab tsi yog qhov sib xyaw ntawm siab purity silicon hmoov?
Kev sib xyaw ua ke tsim ntawm silica fume qhob yog txiav txim siab raws li cov qauv tsim thiab cov qauv tsim qauv xws li silica fume mixing method, cov ntsiab lus zoo ntawm silica fume, cov ntsiab lus zoo ntawm cov dej txo tus neeg sawv cev, thiab kev hloov pob zeb.
1) High-purity silica fume mixing method: Silica fume feem ntau yog tov nrog pob zeb hauv ob txoj kev: ib qho yog kev sib xyaw nrog, thiab lwm yam yog kev sib xyaw sab nraud, siv ua ke nrog cov dej txo. Txoj kev sib xyaw sab hauv siv silica fume es tsis siv cov cement, siv qhov sib npaug ntawm silicon es tsis txhob sib npaug ntawm cov cement, thiab ib feem siv 1 kg ntawm silicon los hloov 1 mus rau 3 kg ntawm cement. Raws li kev tshawb fawb, nws feem ntau yog 5% mus rau 30%, thiab cov nqi dej feem ntau tsis hloov pauv. . Txoj kev sib xyaw sab nraud txhais tau hais tias silica hmoov yog tov rau hauv cov pob zeb zoo li cov khoom sib xyaw.
2) Cov ntsiab lus zoo tshaj plaws ntawm high-purity silica fume: Cov ntsiab lus ntawm silica fume nyob rau hauv cov pob zeb me me dhau lawm thiab yuav tsis txhim kho kev ua tau zoo ntawm cov pob zeb. Txawm li cas los xij, yog tias cov ntsiab lus siab dhau lawm, cov pob zeb yuav txawv dhau, nyuaj rau kev tsim kho, raug kev txom nyem los ntawm qhov loj me me thiab deformation, thiab muaj qhov tsis zoo txias. Thaum sib txuas nrog silica fume, qib siab yuav tsum tau pom kom tau txais cov txiaj ntsig zoo tshaj plaws. Feem ntau hais lus, cov nyhuv yog qhov txaus siab dua yog tias cov ntsiab lus tsis pub dhau 10%. Kev titration ntawm silicon feem ntau yog txiav txim siab los ntawm kev xaiv 3, 5, 7, 10% silicon, thiab lwm yam, raws li hom silica hmoov, cement siv, thiab cov khoom ntawm cov khoom sib sau ua ke, los tsim cov qauv pob zeb, thiab kos tus R. -SF (lub zog-silicon ntsiab lus) nkhaus. Tseeb. Nws yog ib nqi sau cia hais tias tus nqi ntawm silicon hmoov yog siab heev. Kev ntsuas thiab kev lag luam yuav tsum tau txiav txim siab thaum txiav txim siab cov ntsiab lus zoo ntawm silicon fume.
