Eminyakeni yakamuva,i-sodium fluorosilicateivele njengomdlali obalulekile emikhakheni eyahlukene, ikhombisa ukuguquguquka kwayo kanye nokusebenza kwayo kahle ezinhlelweni ezahlukahlukene.
I-sodium fluorosilicate ivela njengekristalu elimhlophe, i-crystalline powder, noma amakristalu angenambala angenama-hexagonal. Ayinaphunga futhi ayinambitheki. Ubuningi bayo obuhlobene bungu-2.68; inamandla okumunca umswakama. Ingancibilikiswa ku-solvent efana ne-ethyl ether kodwa ayincibiliki ku-alcohol. Ukuncibilika ku-asidi kuhle kakhulu kunokwamanzi. Ingancibilikiswa ku-alkaline solution, ikhiqize i-sodium fluoride ne-silica. Ngemva kokusha (300 ℃), incibilikiswa ibe yi-sodium fluoride kanye ne-silicon tetrafluoride.
Izitshalo zokwelapha amanzi emhlabeni wonke ziye zaphendukela kakhulu ku-sodium fluorosilicate njenge-ejenti ephumelelayo ye-fluoridation. Le khompawundi idlala indima ebalulekile ekuthuthukiseni impilo yamazinyo ngokuvimbela ukubola kwamazinyo uma ingezwa emanzini omphakathi. Ucwaningo olunzulu luye lwasekela izinzuzo ze-fluoridation elawulwayo, kanti i-sodium fluorosilicate isibe yisinqumo esikhethwayo ngenxa yokuncibilika kwayo kanye nokusebenza kahle ekufinyeleleni amazinga aphezulu e-fluoride.
Ngaphezu kwendima yayo empilweni yomlomo, i-sodium fluorosilicate isetshenziswa emkhakheni wokwelashwa kobuso bensimbi. Izimboni ezithembele ekumbozweni kwensimbi, njengezimoto kanye nezindiza, zisebenzisa ikhono lale nhlanganisela lokuthuthukisa ukumelana nokugqwala. Izakhiwo zayo eziyingqayizivele ziyenza ibe ukukhetha okuhle kakhulu kokuvikela ubuso bensimbi emiphumeleni emibi yokuchayeka emvelweni, ukuqinisekisa ukuhlala isikhathi eside nokuqina kwezingxenye ezibalulekile.
Imboni yamakhemikhali nayo isebenzise i-sodium fluorosilicate ngendima yayo ekukhiqizweni kwengilazi. Isebenza njenge-ejenti yokushintshashintsha, yenza kube lula ukuncibilika kwezinto zokusetshenziswa emazingeni okushisa aphansi, inciphise ukusetshenziswa kwamandla kanye nezindleko zokukhiqiza. Abakhiqizi bengilazi emhlabeni wonke basebenzisa i-sodium fluorosilicate ukuthuthukisa ukusebenza kahle kwezinqubo zabo ngenkathi begcina ikhwalithi nokucaca komkhiqizo wokugcina.
