I-silicon diokside, kunye nefomula yeekhemikhali i-SiO2, yinto eqhelekileyo ngokugqithisileyo. Ikhona ngokubanzi kwindalo, ukusuka kwintlabathi entle kumanxweme ukuya kwi-quartz ores, inokufumaneka kuyo yonke indawo. Emva kokulungiswa okukhethekileyo, iye yaba sisixhobo esibalulekileyo sokuqinisa-irubha ye-silicone enobushushu obuphezulu.
I-1.I-silicon dioxide inokunyusa amandla erubha ye-silicone
I-silicon dioxide ngokwayo inobunzima obuphezulu. Xa yongezwa kwirabha ye-silicone, kufana nokubeka "isikrweqe" esiqinileyo kumphezulu werabha ye-silicone. Ekusetyenzisweni kwemihla ngemihla, xa iimveliso zerabha ye-silicone zikhuhla kwezinye izinto, lo mhlaba oqinileyo obonelelwa yi-silicon dioxide unokumelana nenxalenye yamandla e-frictional, ukunciphisa ukunxiba ngokuthe ngqo kwe-silicone irabha ye-molecular chain. Umzekelo, -ubushushu obuphezulu berabha yesilicone efakwe kwisilicon dioxide efakwa kwiimoto zokutywina inokugcina ukusebenza okugqwesileyo kokutywinwa kwaye yandise ubomi bayo benkonzo naphantsi kwe{4}}zemeko zokukhuhlana kwexesha elide.
I-2.i-silicon dioxide iphucula ukuxhathisa ukunxiba kwerabha ye-silicone
I-silicon dioksidi inommandla othile ophakamileyo ophezulu kunye nomsebenzi ophezulu, njengokuba nenani "amagwegwe amancinci". Xa idityaniswe kubushushu obuphezulu berabha yesilicone, ezi "huku zincinci" zinokwenza intengiso eyomeleleyo yomzimba kunye neebhondi zekhemikhali kunye ne-silicone yerabha yamatsheyini emolekyuli. Xa irabha ye-silicone ixhomekeke kumandla angaphandle, amasuntswana e-silica anokusasaza ngokulinganayo uxinzelelo. Khawufane ucinge ukuba irabha ye-silicone ngumnatha omkhulu, kwaye i-silica ngamanqaku e-anchor eyomeleleyo asasazwe kumnatha. Xa amandla angaphandle atsala umnatha, amanqaku e-ankile ayawuchithachitha amandla, ethintela uxinzelelo ekugxininiseni kwindawo enye, ngaloo ndlela kuthintelwa ukwaphuka kwangaphambi kwexesha kwamatyathanga erabha yeemolekyuli kunye nokuphucula kakhulu amandla okuqina kunye namandla okukrazula irabha ye-silicone.
