Lub ntsiab sib txawv ntawm precipitated silica thiab fumed silica dag nyob rau hauv particle loj thiab huv.
Precipitated silica feem ntau nyob rau theem micrometer, thaum fumed silica feem ntau yog nyob rau theem ntawm Nanometer. Precipitated silica muaj lub siab impurity cov ntsiab lus thiab lub suab huv ib puag ncig 93%, thaum fumed sihurity cov ntsiab lus thiab lub purity uas tuaj yeem ncav cuag tau ntau tshaj 99%. Vim muaj qhov sib txawv tseem ceeb hauv qhov loj me me thiab huv si, fumed silica outperated silica nyob rau hauv thickipitated silicenated precipitated silicenated precipitated sillica
