1. Ukubuka KweMikhiqizo I-silica e-fumed iyinano-powder esebenzayo eyenziwe ngenqubo ye-fumed (ukuhlanza okushisayo kwe-silicon tetrachloride emlilweni we-oxy-hydrogen). Ingashintshwa ubuso (uhlobo lwe-hydrophobic) noma igcine izakhiwo zayo ezisemqoka ze-hydrophilic ngokuya ngezidingo zokusebenza. Umkhiqizo uhambisana ngokuqinile nezindinganiso zezimboni, izincazelo zamazwe omhlaba ze-ISO 1248-2019, kanye nezidingo zok regulation ze-EU REACH. I-Zhonglian Fumed Silica inezici ezisemqoka ezifaka phakathi ukuhluza okuphezulu (≥99.8%), usayizi we-particle omkhulu (7-40nm), kanye nesakhiwo esihlanganisiwe esifana nenethiwekhi (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lubonisa i-hydrophilicity enhle kanye nokuhlanganiswa, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (ukuhlangana kwamanzi ≥120°, ukumuncwa kokungcola ≤0.5%). Ezinhlakeni zokunamathela, ukumboza, kanye nezinhlelo zokwakha, inikeza imisebenzi eyinhloko efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqinisa, kanye nokumelana nokuhlaselwa. Ngasikhathi sinye, inezinga elihle lokuzinza kwemichiza futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene ezihlanganisa ezisekelwe kumasampula, ezingenamasampula, nezisekelwe emanzini, ihlangabezana nezidingo eziqinile zokuhambisana kokusebenza nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
