Yintoni iSilicon Dioxide CAS 7631-86-9?

I-silicon dioxide yi-arhente yokuqinisa irabha elungileyo, enokuphucula kakhulu amandla okuqina kunye nokumelana nokunxiba kwerabha evulziweyo, ukunciphisa inani lerabha esetyenzisiweyo, ukunciphisa iindleko, kunye nobudlelwane olomeleleyo, iyenza ibe namandla okusasazwa okukhulu kwirabha ekrwada. Iimpawu ezibonakalayo ezenziwe ngamasuntswana e-silica kunye ne-rubber particles zingcono kunezo zekhabhoni ezimnyama ekwandiseni amandla omatshini kunye namandla okukrazula irabha evuzayo.

Isicelo

I-silicon dioxide isetyenziswa kumashishini afana namatayara, iimveliso zerabha ezingafihliyo nezingafihliyo, kunye neentambo zerabha kunye neentambo. Isetyenziswa kakhulu kwiimveliso zerabha ezifana namabhanti okuhambisa kunye neerola zerabha.

I-Silica (SiO2) (RI: 1.48) yombiwa kwiidiphozithi ze-diatomaceous soft chalk-like rock (keiselghur). Eli liqela elibalulekileyo lee-extender pigments, ezisetyenziswa kwiintlobo ngeentlobo zobukhulu bamasuntswana. Zisetyenziswa njenge-agent ethe tyaba ukunciphisa ukukhazimla kweeayiti ezicacileyo kunye nokubonelela ngeempawu zokucheba ezibhityileyo kwiingubo. Abiza kakhulu.
