I-silicon dioxide, enefomula yamakhemikhali i-SiO2, iyinhlanganisela evamile kakhulu ye-inorganic. Itholakala kakhulu emvelweni, kusukela esihlabathini esihle emabhishi kuya kuma-quartz ores, ingatholakala yonke indawo. Ngemva kokucutshungulwa okukhethekile, isibe isigcwalisi esibalulekile sokugcwalisa{3}}irabha ye-silicone enezinga lokushisa eliphezulu.
I-1.I-Silicon dioxide ingathuthukisa amandla erabha ye-silicone
I-silicon dioxide ngokwayo inobulukhuni obuphakeme kakhulu. Uma yengezwa kurabha ye-silicone, kufana nokugqoka "isivikelo" esiqinile ebusweni berabha ye-silicone. Ekusetshenzisweni kwansuku zonke, lapho imikhiqizo yerabha ye-silicone ihlikihla kwezinye izinto, le ndawo eqinile ehlinzekwa i-silicon dioxide ingamelana nengxenye yamandla akhuhlanayo, inciphise ukuguga okuqondile kwamaketanga e-molecular yerabha ye-silicone. Isibonelo,{3}}irabha ye-silicone enezinga lokushisa eliphezulu efakwe ku-silicon dioxide esetshenziswa kuma-automotive seal ingagcina ukusebenza kahle kokuvala futhi inwebe impilo yayo yesevisi ngisho nangaphansi{4}}izimo zokungqubuzana zesikhathi eside.
I-2.silicon dioxide ithuthukisa ukumelana nokugqokwa kwerabha ye-silicone
I-Silicon dioxide inendawo ethize ephezulu kanye nomsebenzi ophezulu, njengokuba nenani "amahhuku amancane". Uma yengezwa-kumazinga okushisa e-silicone enjoloba evundile, lawa "mahhuku amancane" angakha i-adsorption eqinile ebonakalayo kanye namabhondi amakhemikhali ngamaketanga emolekyuli yerabha ye-silicone. Lapho irabha ye-silicone ingaphansi kwamandla angaphandle, izinhlayiya ze-silica zingahlakaza ngokulinganayo ukucindezeleka. Cabanga ukuthi irabha ye-silicone iyinethi enkulu, futhi i-silica iyindawo eqinile yehange esakazwa enethini. Lapho amandla angaphandle edonsa inetha, amaphuzu okubamba ihange ahlakaza amandla, avimbele ukucindezeleka ekugxileni endaweni eyodwa, ngaleyo ndlela kuvinjwe ukuphuka ngaphambi kwesikhathi kwamaketanga erabha yamangqamuzana enjoloba futhi kwandise kakhulu amandla aqinile namandla okudabula erabha ye-silicone.
