I-Silica ikwabizwa ngokuba yi-silicone dioxide.I-silica ineendlela ezahlukeneyo zokusebenzisa: ukulawula i-viscosity yemveliso, ukongeza ubuninzi, kunye nokunciphisa ukucaca kokuqulunqwa.Iyakwazi ukusebenza njenge-abrasive.Ukongeza, inokusebenza njengesithwala i-emollients, kwaye ingasetyenziselwa ukuphucula ukuvakalelwa kolusu lwendlela.I-silica engqukuva inemingxuma kwaye ifunxa kakhulu, inamandla okufunxa ngokuqikelelwa ngokuphindwe ka-1.5 ubunzima bayo.Ibango eliqhelekileyo elihambelana ne-silica kukulawula ioli.Ifumaneka kwi-sunscreens, i-scrubs, kunye nolunye uluhlu olubanzi lokunakekelwa kwesikhumba, izimonyo, kunye nokulungiswa kweenwele.Isetyenziswe ngempumelelo kwi-hypoallergenic kunye ne-allergies-tested formulations.
I-Silica (SiO2) (RI: 1.48) yombiwa kwiidiphozithi ze-diatomaceous soft chalk-like rock (keiselghur).Eli liqela elibalulekileyo lee-extender pigments, ezisetyenziswa kwiintlobo ngeentlobo zobukhulu bamasuntswana.Zisetyenziswa njenge-agent ethe tyaba ukunciphisa ukukhazimla kweeayiti ezicacileyo kunye nokubonelela ngeempawu zokucheba ezibhityileyo kwiingubo.Abiza kakhulu.
I-silicon (IV) i-oxide, i-amorphous isetyenziswe njengabathwali, izixhobo zokusebenza, i-anti-caking kunye ne-free-flow agents kwisondlo sezilwanyana.Izicelo ze-Defoamer ezifana nepeyinti, ukutya, iphepha, i-textile kunye nezinye izicelo zamashishini.Ii-silicon dioxide zokwenziwa zisetyenziswa njengearhente yolawulo lwerheology kwiiplastiki.Ikwasetyenziselwa ukwenza i-adhesives, sealants kunye ne-silicones.
Ukwenziwa kweglasi, iiglasi zamanzi, iirefractories, abrasives, ceramics, enamels;i-decolorizing kunye nokucoca ioli, iimveliso zepetroleum, njl.;kwi-scouring- kunye nee-compounds zokugaya, i-ferrosilicon, i-molds for castings;njenge-anticaking kunye ne-ejenti yokukhupha ugwebu.
