Sharaxaada Alaabta

Hordhac kooban

Magaca alaabta: Silicon oxide SiO2
Daahirsanaanta: 99%-99.999%
Cabbirka qaybta: 20-30nm, 50nm, 100nm, 45um, 100un, 200um, iwm
Nooca: hydrophilic, hydrophobic
Midabka: budo cad
Cufnaanta Weyn: <0.10 g/cm3
Cufnaanta Dhabta ah: 2.4 g/cm3
Milicsiga Ultraviolet:>75%.

Astaamaha:

Qaybaha Nano-silica marka loo eego qaab-dhismeedkooda waxa loo qaybiyaa laba nooc: P-type (Pimples Porous) iyo S-type (Spherical particles). Nooca P-nano-silica dusha sare wuxuu ka kooban yahay tiro nano-porous ah oo leh heerka daloolka 0.611ml / g; Sidaa darteed, nooca P-ga waxa uu leeyahay SSA aad uga weyn marka loo eego nooca S (eeg US3440). US3436 waa S-nooca SSA-na waa ~170-200m2/g. Intaa waxaa dheer, P-nooca ultraviolet milicsiga waa> 85%, S-nooca:>75%.
