كيفية تحسين أداء طوب العزل الموليت خفيف الوزن？

طوب العزل الموليت خفيف الوزن لديه درجة حرارة تليين عالية, مسامية منخفضة, ومقاومة جيدة للتآكل. إنها مواد عزل عالية الجودة. Mullite insulation bricks with different physical and chemical indicators have different insulation effects. كيفية تحسين أداء طوب موليت خفيف الوزن?

What factors affect the performance of lightweight mullite insulation bricks?

Mullite insulation bricks usually contain impurity oxides such as TiO₂、Fe₂O3、CaO、MgO、ك₂O and Na₂ا. 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, ك₂O 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 Al₂ا₃ 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 K₂ا, بالفعل₂O and Fe₂ا₃, which is an important measure to obtain high-quality lightweight mullite insulation bricks.
