Silica a na-akpọ Hydrophobic
Okwu Mmalite Ngwaahịa
Silica a na-akpọ ọkụ, ma ọ bụsilica pyrogenic, colloidal silicon dioxide, bụ ntụ ntụ inorganic ọcha amorphous nke nwere oke elu pụrụ iche, nha obere ihe nano na oke dị elu (n'etiti ngwaahịa silanol) nke otu silanol elu. Enwere ike ịgbanwe àgwà nke silica a gbanyere ọkụ site na mmeghachi omume ya na otu silanol ndị a.
Enwere ike kewaa silica a na-ere ere n'ime otu abụọ: silica a na-ere ọkụ na silica a na-ere ọkụ na-ekpo ọkụ na hydrophobic. A na-ejikarị ya eme ihe dị ka ihe dị mkpa n'ọtụtụ ụlọ ọrụ dịka rọba silicone, agba na plastik.
