Silicon dioxide, ine kemikari formula SiO2, yakajairika zvakanyanya inorganic compound. Inowanikwa zvakanyanya mumasikirwo, kubva kune jecha rakanaka pamahombekombe kusvika kune quartz ores, inogona kuwanikwa kwese kwese. Mushure mekugadzirwa kwakakosha, yave yakakosha yekusimbisa kuzadza kune yakakwirira-tembiricha ine vulcanized silicone rabha.
1.Silicon dioxide inogona kuwedzera simba resilicone rubber
Silicon dioxide pachayo ine hurema hwakanyanya. Kana yawedzerwa kune silicone rabha, yakafanana nekuisa "simbi" yakaoma pamusoro peiyo silicone rubber. Mukushandiswa kwemazuva ese, kana zvigadzirwa zverubha zvesilicone zvichikwesha kune zvimwe zvinhu, iyi yakaoma nzvimbo yakapihwa nesilicon dioxide inogona kumirisana nechikamu chesimba rekupokana, ichideredza kupfekedzwa kwakananga kwesilicone rubber molecular cheni. Semuyenzaniso,-tembiricha yakakwira vulcanized silicone rabha ine sililicon dioxide yakaiswa pazvisimbiso zvemotokari inokwanisa kuchengetedza kuvharika kwakanaka uye kuwedzera hupenyu hwayo hwesevhisi kunyangwe pasi pe-nguva refu friction.
2.silicon dioxide inosimudzira kupfeka kusagadzikana kwesilicone rubber
Silicon dioxide ine yakakwira chaiyo nzvimbo uye chiitiko chepamusoro, sekunge kuve ne "zvikorekedzo zvidiki" zvisingaverengeki. Kana yawedzerwa kune yakakwirira-tembiricha yakanyungudutswa yesilicone rabha, "zvikorekedzo zvidiki" izvi zvinogona kuumba adsorption akasimba emuviri nemakemikari bond nesilicone rubber molecular cheni. Kana silicone rabha ichiiswa pasi pesimba rekunze, silica zvimedu zvinogona kuparadzira zvakaenzana kushushikana. Fungidzira kuti silicone rabha mambure makuru, uye silica ndiyo yakasimba anchor points yakagoverwa pamambure. Kana simba rekunze richikweva mambure, mapoinzi eanchor anoparadzira simba racho, zvichidzivirira kushushikana kubva mukunangana munzvimbo imwechete, nekudaro kudzivirira kutsemuka kusati kwasvika kwerabha molecular cheni uye kuwedzera zvakanyanya simba rekusimba uye kubvarura simba resilicone rabha.
