Last issue, we mainly talked about the performance and application of mullite insulation fire brick. In this issue, we will mainly talk about its characteristics.
Characteristics of mullite insulation fire brick
1. Use foaming machine to produce bubbles in lightweight mullite insulation fire brick can obtain bubbles with uniform diameter.
2. The bubbles in bricks are independent, it is not easy to form connected holes. And the foamed concrete has a high closed cell ratio, so it has good thermal insulation and waterproof performance.
3. Use lightweight mullite thermal insulation fire bricks to produce foam concrete with a dry density of 300 to 1,200kg/m3 can reduce the amount of foam and improve the economic benefits.
4. Light mullite insulation fire brick has good adaptability to cement.
5. It is environmental friendly, non-toxic, non-corrosive, and safe to use.
6. Lightweight mullite insulation fire bricks are inexpensive and can greatly reduce costs.
7. Excellent foaming performance. Foaming ratio can be more than 30 times
