Chii chinonzi Silicon Dioxide CAS 7631-86-9?

Silicon dioxide chinhu chakanaka chinosimbisa rabha, chinogona kuvandudza simba rekusunga uye kuramba kupfeka kwerabha rakaputirwa, kuderedza huwandu hwerabha rinoshandiswa, kuderedza mitengo, uye kuva nesimba rakasimba, zvichiita kuti rikwanise kupararira zvakanyanya murabha risina kuputirwa. Hunhu hwepanyama hunoumbwa nezvidimbu zvesilica nezvidimbu zverabha huri nani pane hwekabhoni nhema mukuwedzera simba remakanika uye simba rekubvaruka kwerabha rakaputirwa.

Kushandiswa

Silicon dioxide inoshandiswa mumaindasitiri akadai sematairi, zvigadzirwa zverabha zvinopenya zvishoma uye zvakakwirira, pamwe chete netambo dzerabha netambo. Inonyanya kushandiswa muzvigadzirwa zverabha zvakaita semabhandi ekufambisa zvinhu nemaroller erabha.

Silica (SiO2) (RI: 1.48) inocherwa kubva mumatombo edombo rakapfava rakaita sechaki (keiselghur). Iri iboka rakakosha remapigment ekuwedzera, anoshandiswa muhukuru hwakasiyana-siyana hwezvikamu. Anoshandiswa senzira yekupeta kuti aderedze kupenya kwemavara akajeka uye kupa hunhu hwekuyerera kwemavara kumavara. Anodhura zvakanyanya.
