JM Series Bubble Mullite Insulating Refractory Brick for Tunnel Kiln
The Description:
Mullite insulation brick It is made of high bauxite clinker as the main material, plus a small amount of clay. Good protection of clay resources, so the emergence of mullite insulation bricks when the product of modern science and technology, aluminum used to be the aristocracy can use things, but modern technology makes aluminum this resource can be used to produce a variety of products. The performance of Mullite insulation brick, high refractoriness, can resist high temperatures of 1800 degrees Celsius, but at 1600 to 1700 degrees Celsius, the insulation brick will begin to soften and will not burn.
