Nta:
Nano--silica hais raws li lawv cov qauv tau muab faib ua ob hom: p-hom (ntxeem tau) thiab s-hom (kheej kheej). P-hom nano-silica dego muaj ntau tus nano-ntxeem nrog tus nqi pore ntawm 0.611ml / g; Yog li ntawd, P-hom muaj ntau dua loj ssa sib piv rau s-hom (saib US3440). US3436 yog S-hom thiab nws SSA yog ~ 170-200m2 / g. Ntxiv mus ntxiv, P-hom ultraviolet refreas refreasing yog> 85%, S-hom:> 75%.
