Test Method:
1. Transmission electron microscopy (TEM) txoj kev, nano-silica particle muaj me me, nqaim particle loj tis.
2. BET txoj kev, nano-silica particle muaj thaj tsam loj.
3. Infrared spectroscopy txoj kev, nano-silica particle muaj ib tug loj tus naj npawb ntawm hydroxyl pawg thiab unsaturated residual bonds nyob rau hauv nws nto, thiab tsim cov deviation los ntawm qhov khov kho ntawm silicon oxide qauv.
4. Cary-5E spectrophotometer test method, nano-silica particles - siab reflectivity rau ntev nthwv dej thiab pom lub teeb txog UV.
5. Omnisorp100CX nto cheeb tsam thiab porosity analyzer, P-hom nano-silica nto muaj ib tug xov tooj ntawm nano ntxeem tau nrog lub pore tus nqi ntawm 0.611ml / g.
