Kev Qhia
Microsilica, tseem hu ua silica fume, yog kev ua haujlwm ntawm kev ua cov tshuaj silicon hlau lossis ferrosilicon alloys. Silicon hlau thiab alloys yog tsim hauv qhov cub hluav taws xob. 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 cov av ntim. Microsilica muaj feem ntau ntawm amorphous (tsis-crystalline) silicon dioxide (SiO 2 ), nws qhov nruab nrab granule taub yog 0.15 ~ 0.20 µm, thaj chaw tshwj xeeb thaj tsam yog 15000 ~ 20000 m 2 / kg, thiab nws muaj zog tsis tshua muaj siab ua haujlwm.
Lub ntsiab muaj nuj nqi
Low Tsawg heev permeability rau chloride thiab dej nkag.
Tshaj tawm hluav taws xob tsis tshua muaj qhov siab (20 txog 100 npaug ntau dua ntawm cov qhob yooj yim)
Muaj kev ua kom zoo ntawm cov nqov nyom, cov plag tsev, txoj kev loj thiab cov nkoj hiav txwv.
Ior Superior tsis kam mus rau kev siv tshuaj los ntawm chlorides, acids, nitrates thiab sulfates.
