I-silica yaziwa nangokuthi i-silicone dioxide.I-silica inezinhlelo zokusebenza ezihlukahlukene: ukulawula ukubukeka komkhiqizo, ukwengeza inqwaba, nokunciphisa ukuvezwa kokwakheka.Ingase futhi isebenze njenge-abrasive.Ngaphezu kwalokho, ingasebenza njengesithwali sama-emollients, futhi ingase isetshenziselwe ukuthuthukisa umuzwa wesikhumba owenziwe.I-silica eyindilinga inezimbotshana futhi imunca kakhulu, inamandla okumunca cishe izikhathi ezi-1.5 isisindo sayo.Isimangalo esijwayelekile esihlotshaniswa ne-silica ukulawula uwoyela.Itholakala kuma-sunscreens, ama-scrubs, kanye nohlu olubanzi lwezinye ukunakekelwa kwesikhumba, izimonyo, namalungiselelo okunakekelwa kwezinwele.Isetshenziswe ngempumelelo ekwakhiweni kwe-hypoallergenic kanye ne-allergies.
I-Silica (SiO2) (RI: 1.48) yembiwa emalini yetshe elithambile elifana ne-diatomaceous (keiselghur).Leli yiqembu elibalulekile lama-extender pigments, asetshenziswa ezinhlobonhlobo zamasayizi wezinhlayiyana.Zisetshenziswa njenge-ejenti eyisicaba ukuze kuncishiswe ukucwebezela kwezingubo ezicacile futhi zinikeze izakhiwo zokugeleza zokucwenga kwe-shear kuma-coatings.Abiza kakhulu.
I-silicon(IV) oxide, i-amorphous isetshenziswa njengabathwali, izinsiza zokucubungula, i-anti-caking kanye nama-free-flow agents ekudleni kwezilwane.Izicelo ze-Defoamer ezifana nopende, ukudla, iphepha, izindwangu nezinye izinhlelo zokusebenza zezimboni.Ama-silicon dioxide okwenziwa asetshenziswa njenge-ejenti yokulawula i-rheology kumapulasitiki.Ibuye isetshenziselwe ukwenza ama-adhesives, ama-sealants nama-silicones.
Ukwenziwa kwengilazi, ingilazi yamanzi, iziqhoboshi, iziqholo, izitsha zobumba, izinsimbi;i-decolorizing kanye nokuhlanza amafutha, imikhiqizo ye-petroleum, njll.;kuma-compounds wokugaya nokugaya, i-ferrosilicon, isikhunta sokubunjwa;njenge-anticaking kanye ne-ejenti yokuqeda amagwebu.
