Hydrophobic SiO2 nano ufa wathu umakonzedwa ndi organic hybridization ndipo njira yopangira ndi gawo la nthunzi.

Mosiyana ndi silika yoyambirira ya hydrophilic, silika ya hydrophobic fumed silinganyowetsidwe ndi madzi.Ngakhale kachulukidwe ka silika wa hydrophobic fumed ndi wamkulu kuposa wamadzi, amatha kuyandama pamadzi.Ndi pamwamba mankhwala a fumed silika, ntchito yake luso akhoza wokometsedwa m'madera ena enieni ntchito, amene angathe bwino kusintha rheological katundu ambiri madzi polima kachitidwe, makamaka kachitidwe epoxy utomoni.

Fumed silica ndi imodzi mwazofunikira kwambiri zaukadaulo wapamwamba kwambiri waukadaulo wamakono.Chifukwa chaching'ono tinthu kukula, ali lalikulu enieni padziko, amphamvu padziko adsorption, mkulu mankhwala chiyero, uthenga kubalalitsidwa, matenthedwe kukana, kukana magetsi, etc. The ntchito yapadera, ndi apamwamba bata, kulimbikitsa, thickening ndi thixotropy, ali mawonekedwe apadera m'magawo ambiri ndi magawo, ndipo ali ndi gawo losasinthika.Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zowonjezera, zonyamulira zonyamula, mafuta a petrochemicals, zolimbitsa mphira, zodzaza pulasitiki, zokutira inki, zofewa zazitsulo zopukutira, zotsekera ndi zotchingira kutentha, zodzaza zodzikongoletsera zapamwamba zatsiku ndi tsiku ndi zida zopopera, ndi zina zambiri.
