1. Ukuhlaziywa Komkhiqizo 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 izici zayo ezisemqoka ze-hydrophilic ngokuya ngezidingo zokusebenza. Umkhiqizo uhambisana ngokuqinile nezindinganiso zezimboni, izincazelo zamazwe omhlaba ze-ISO 1248-2019, kanye nezidingo zokulawula ze-EU REACH. I-Zhonglian Fumed Silica inezici eziyisisekelo ezihlanganisa ukujula okuphezulu kakhulu (≥99.8%), usayizi we-particle oyinhloko we-nano-scale (7-40nm), kanye nesakhiwo se-network esithathu (indawo ethile: 50-400 m²/g). Phakathi kwazo, uhlobo lwe-hydrophilic lukhombisa i-hydrophilicity enhle kanye ne-dispersibility, kanti uhlobo lwe-hydrophobic lukhombisa i-hydrophobicity ephawulekayo (ukuhlangana kwamanzi ≥120°, uku吸湿 ≤0.5%). Ku-adhesive, coating, kanye nezinhlelo zokwakha ezihlanganisiwe, inikeza imisebenzi eyinhloko efana nokwandisa, ukuthuthukiswa kwe-thixotropy, ukuvimbela ukuhamba, ukuvimbela ukuwa, ukuqina, kanye nokumelana nokuhlanza. Ngasikhathi sinye, inezinga elihle lokuzinza kwezem kemikhakha futhi iyahambisana nezinhlelo zokukhiqiza ezahlukene kuhlanganise nezisekelo ze-solvent, ezingenazo izixazululo, nezisekelo zamanzi, ihlangabezana nezidingo eziqinile zokusebenza okuqhubekayo nokwethembeka emikhiqizweni ephakathi nendawo kuya phezulu. 2.
