Ingoa hua:Silicon oxide SiO2
Maamaa: 99%-99.999%
Rahi matūriki: 20-30nm, 50nm, 100nm, 45um, 100un, 200um, aha atu
Momo: hydrophilic, hydrophobic
Tae: paura ma
Kiato Nui: <0.10 g/cm3
Kiato Pono: 2.4 g/cm3
Whakaata Ultraviolet:>75%.

Āhuatanga:

Matūriki Nano-silikas rite ki to ratou hanganga kua wehea ki e rua momo: P-momo (matūriki poro) me S-momo (Matūriki porohita). P-momo nano-silica mata he maha o te nano-porous me te tere pore o 0.611ml /g; no reira, he nui ake te SSA momo-P ki te whakataurite ki te momo-S (Tirohia te US3440). Ko te US3436 he momo-S me tana SSA he ~170-200m2/g. I tua atu, P-momo ultraviolet reflectivity he> 85% , S-momo:> 75%.

Nga Tikanga Whakamatau:

1. Te tikanga tuku irahiko microscopy (TEM),matūriki nano-silicahe iti te rahi, he kuiti te tohatoha matūriki.
2. Ko te tikanga BET, ko te matūriki nano-silica he nui te waahanga mata motuhake.
3. Ko te tikanga whakakitenga infrared, he matūriki nano-silica te maha o nga roopu hydroxyl me nga here toenga haunga kore i runga i te mata, ka hanga i te rereke mai i te ahua pumau o te hangahanga waikura silicon.
4. Cary-5E tikanga whakamātautau spectrophotometer, matūriki nano-silica--te whakaata teitei ki te ngaru roa me te marama e kitea ana mo te UV.
5. Omnisorp100CX rohe mata me te porosity tātaritanga, P-momo nano-silica mata kei roto i te maha o nano porous ki te tere pore o 0.611ml /g.
