Vaega

Nano-silic particles e tusa ai ma lo latou fausaga ua vaevaeina i ni ituaiga se lua: P-ituaiga (Porous particles) ma S-ituaiga (Spherical particles).P-ituaiga nano-silic surface o loʻo i ai se numera o nano-porous ma le fua o le pore o le 0.611ml / g;o lea, P-ituaiga e sili atu le tele o SSA faʻatusatusa i S-ituaiga (Vaai US3440).US3436 o le S-ituaiga ma lona SSA e ~ 170-200m2/g.E le gata i lea, o le P-ituaiga ultraviolet reflectivity o le> 85%, S-ituaiga:> 75%.

Metotia Su'ega

1. Transmission electron microscopy (TEM) metotia, nano-silic particle e laʻititi laʻititi, vaapiapi faʻasoa faʻasoa.
2. BET auala, nano-silic particle ei ai le tele o luga vaega faapitoa.
3. Infrared spectroscopy metotia, nano-silic particle o loʻo i ai se numera tele o vaega o le hydroxyl ma faʻamaufaʻailoga o loʻo totoe i luga o lona luga, ma faʻatupuina le vavae ese mai le tulaga mautu o le fausaga o le silicon oxide.
4. Cary-5E spectrophotometer metotia su'ega, nano-silic particles-maualuga le atagia i galu umi ma le malamalama vaaia e uiga i le UV.
5. Omnisorp100CX pito i luga ma le porosity analyzer, P-ituaiga nano-silic surface o loʻo i ai se numera o nano porous ma le fua o le pore o le 0.611ml / g.
