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 ichiwedzera zvishoma 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.
