Features:
Nano-silica particles maererano nemaitiro avo akakamurwa kuva marudzi maviri: P-mhando (Porous particles) uye S-mhando (Spherical particles). P-type nano-silica surface ine nhamba ye nano-porous ine pore rate ye 0.611ml / g; saka, P-mhando ine yakakura zvikuru SSA tichienzanisa S-mhando (Ona US3440). US3436 iS-mhando uye SSA yayo iri ~170-200m2/g. Uyezve, P-mhando ultraviolet reflectivity iri> 85%, S-mhando:> 75%.

Nzira dzekuedza:
1. Transmission electron microscopy (TEM) nzira, nano-silica particle ine diki diki, nhete particle size distribution.
2. BET nzira, nano-silica particle ine yakakura chaiyo nzvimbo.
3. Infrared spectroscopy method, nano-silica particle iripo nhamba huru ye hydroxyl mapoka uye unsaturated residual bonds pamusoro payo, uye inoumba kutsauka kubva kune yakagadzikana mamiriro esilicon oxide chimiro.
4. Cary-5E spectrophotometer yekuedza nzira, nano-silica particles--high reflectivity kune refu wave uye chiedza chinooneka pamusoro peUV.
5. Omnisorp100CX nzvimbo yepamusoro uye porosity analyzer, P-type nano-silica surface ine nhamba ye nano porous ine pore rate ye 0.611ml / g.

Application:
1 Rubha yakagadziridzwa, sealant ceramic toughening modification, zvinonamira, zvinoshanda fiber additive, kugadziridzwa kwepurasitiki, pendi kuchembera zvinowedzera;
2 Ceramics, nano ceramic, composite ceramic substrate;
3 Polymer: inogona kuwedzera kugadzikana kwekupisa uye anti-kuchembera polymer;
4 Zvishandiso zvinodzoreredza moto uye machira, svikiro rakakwirira, zvigadzirwa zvekuzora;
5 Mu cluster butyl benzene uye chlorinated polyethylene inowedzera shoma shoma ye nano SiO2 inoburitsa ruvara rubber kutsungirira,
kureba, simba, flexural performance uye ultraviolet kuramba uye kupisa kuchembera kuita uye kuwana kana kudarika epdm;
6 Muchinyakare coating kuwedzera shoma shomanano silicon oxides, zvakanaka gadzirisa kugadzikana kwekumiswa, thixotropy uye murombo, kupera kwakashata.
