Iyini i-Silicon Dioxide CAS 7631-86-9?

I-Silicon dioxide iyi-ejenti enhle eqinisa irabha eqinisayo, engathuthukisa kakhulu amandla aqinile kanye nokumelana nokugqoka kwenjoloba ene-vulcanized, inciphise inani lenjoloba esetshenzisiwe, inciphise izindleko, futhi ibe nokuhlobana okuqinile, iyenze ibe nekhono elikhulu lokuhlakazeka kwerabha eluhlaza. Izakhiwo ezibonakalayo ezakhiwe yizinhlayiya ze-silica nezinhlayiya zenjoloba zingcono kunekhabhoni emnyama ekuthuthukiseni amandla emishini namandla okudabula enjoloba eshisiwe.

Isicelo

I-Silicon dioxide isetshenziswa ezimbonini ezinjengamathayi, imikhiqizo yerabha ebonisa ngale kanye nephezulu, kanye nezinsimbi zenjoloba nezintambo. Isetshenziswa kakhulu emikhiqizweni yenjoloba njengamabhande okuthutha kanye namarola erabha.

I-Silica (SiO2) (RI: 1.48) yembiwa emalini yetshe elithambile elifana ne-diatomaceous (keiselghur). Leli yiqembu elibalulekile lama-extender pigments, asetshenziswa ezinhlobonhlobo zosayizi bezinhlayiyana. Zisetshenziswa njenge-ejenti eyisicaba ukuze kuncishiswe ukucwebezela kwezingubo ezicacile futhi zinikeze izici zokugeleza zokucwenga kwe-shear kuma-coatings. Abiza kakhulu.
