Khoom Description

Micro silica, tseem hu ua silica fume lossis micro silica, yog cov khoom lag luam ntawm silicon hlau lossis ferrosilicon alloys. Silicon hlau thiab alloys yog tsim nyob rau hauv hluav taws xob furnaces.Cov ntaub ntawv raw yog quartz, thee thiab woodchips.Cov pa taws uas tshwm sim los ntawm lub cub tawg yog sau thiab muag raws li silica fume, silica fume muaj feem ntau ntawm amorphous (non-crystalline) silicon dioxide (SiO2). ), nws qhov nruab nrab granule txoj kab uas hla yog 0.15 ~ 0.20um, tshwj xeeb thaj chaw yog 15000 ~ 20000m2 / kg, thiab nws muaj zog heev nto active.
