Txoj haujlwm ntawm semi silica cib

Semi - Silica Cib yog tsim nrog kev siv cov ntaub ntawv av nplaum - raws li cov ntaub ntawv refractory ntawm cov ntsiab lus siab sio₂. Lawv ua tiav los ntawm tshuab nias thiab raug rho tawm haujlwm ntawm qhov kub. Cov khoom lag luam tsawg heev porosity, siab ntom thiab lub zog siab. Tshwj xeeb, tus nqi nkag yog tsawg heev, tsuas yog hais txog {2}}. 08% ntawm 1050 degree rau (5 - 25 h). Thaum lub sijhawm thov, lawv cov txiaj ntsig zoo tshaj plaws yog cov anti siab - kev nkag mus thiab acid - corrosion tsis kam. Yog li ntawd, semi - silica bricks tau siv dav nyob rau hauv cov kab ntawm cov khoom siv xws li Coke Ncu, tsis yog - Ferrous hlau smetting chaw thiab torpedo tsheb.
