Dab tsi yog Silica Fume?
Apr 23, 2020
Silica fume yog qhov ua tau los ntawm kev tsim cov tshuaj silicon hlau lossis ferrosilicon alloys. Ib qho ntawm cov txiaj ntsig zoo siv rau silica fume yog nyob hauv cov pob zeb. Vim tias nws cov tshuaj lom neeg thiab lub cev, nws yog tshuaj lom neeg pozzolan heev. Cov pob zeb ua muaj silica fume tuaj yeem muaj lub zog zoo heev thiab tuaj yeem ua ruaj khov. Silica fume muaj muag los ntawm cov chaw muag khoom ntawm cov pob zeb ua admixtures thiab, thaum sau tseg, tsuas yog ntxiv thaum lub sijhawm kev ua vaj tse. Kev ua tiav, ua kom tiav, thiab siv cov pob zeb ua kua silica-fume yuav tsum muaj kev tshwj xeeb rau ntawm cov ntu ntawm tus kws ua vaj tse.
Cov ntaub ntawv raw yog quartz, thee, thiab woodchips. Cov pa luam yeeb uas tau tshwm sim los ntawm kev ua haujlwm rau lub cub tawg yog sau thiab muag li silica fume, es tsis yog muab pov tseg. Tej zaum qhov tseem ceeb tshaj plaws ntawm kev siv cov khoom siv no yog cov ntxhia hauv pob zeb ua ke.
