Cum să îmbunătățiți performanța cărămizilor ușoare de izolare cu mulit?

Cărămizile ușoare de izolare cu mulit au o temperatură ridicată de înmuiere a sarcinii, porozitate scăzută, și rezistență bună la coroziune. Sunt materiale izolante de înaltă calitate. Mullite insulation bricks with different physical and chemical indicators have different insulation effects. Cum să îmbunătățești performanța cărămizii de mullit cu greutate redusă?

What factors affect the performance of lightweight mullite insulation bricks?

Mullite insulation bricks usually contain impurity oxides such as TiO₂、Fe₂O3、CaO、MgO、K₂O and Na₂O. The impurity content in mullite produced from natural raw materials is higher than that in synthetic raw materials. These impurities Oxides act as fluxes in mullite, and the effects of various oxide impurities are different. Among them, K₂O and Na₂O have the greatest influence on the liquid phase formation temperature, and TiO₂ has the least influence.

Improve the performance of lightweight mullite insulation bricks

If you want to improve the insulation performance of mullite insulation bricks, you need to control the content of impurities. With the increase of Al₂O₃ content in mullite bricks, the insulation performance will increase, but the increase in impurities will reduce the insulation performance, especially It is the content of K₂O, Deja₂O and Fe₂O₃, which is an important measure to obtain high-quality lightweight mullite insulation bricks.
