Silica Zvidhina

Silica zvidhinha zvinoreva zvigadzirwa zvine SiO2 zvemukati pamusoro pe90%. Silica chidhinha chakagadzirwa nesilica ine SiO2 zvemukati zvisiri pasi pe96% senge mbishi zvinhu.

Iyo yakagadzirirwa nekuvhenganisa, kuumba, kuomesa uye kusvina iyo mineralizer uye inosunga mumiririri. Iyo yakakwira iyo SiO2 zvemukati mune iyo silica mbishi zvinhu, iyo inokwidziridzwa iyo yekutsoropodza kwechigadzirwa. Kune mhando dzakasiyana dzemasilina zvidhinha, izvo zvakakamurwa kuita: silika zvidhinha zvecokoni ovhoni, silika zvidhinha zvemoto unopisa zvitofu, silika zvidhinha zvemagetsi emagetsi, uye silika zvidhinha zvemagirazi kilns. Zvinoenderana neshanduko iyi, yakakamurwa kuita: zvidhinha zvakajairika, zvidhinha zvakajairika, zvidhinha zvakaumbwa-zvakaenzana uye zvidhinha zvakaumbwa.

Hunhu hwe silika zvidhinha:

Silica zvidhinha ndeye acidic inoratidzira zvinhu, ine yakasimba kuramba acid acid kana acid mhinduro. Iyo yepamusoro yekupfavisa tembiricha iri pasi pemutoro hunhu hwakanaka hwesilica zvidhinha, kazhinji 1640-1680 ℃.
