Light Weight Mullite Insulation Brick
Light Weight Mullite Insulation Brick, mainly based on aluminum silicate-based refractory materials, with some excellent performance, (especially high temperature creep performance) living in natural raw materials production Of the high aluminum products first.
Mullite composition AL203 in about 79%, Si02 in 21% is more appropriate, but there are a certain amount of raw materials in the impurity composition, at high temperatures will cause the composition of the composition, so as the impurity composition increases, will make vitreous and corundum And the molybdenum is formed into coarse grain structure, which makes the porosity of the product increase, the thermal shock stability and corrosion resistance are reduced, and cracks are likely to occur.
Product Advantages:
- Low levels of iron and other impurities
- High mechanical intensity
- High refractoriness, can contact with the flame directly, suitable for various atmosphere
- High porosity, low volume density, low thermal conductivity
- Good heat insulating performance and energy-efficient
- Low creep rare at high temperature,good thermal shock stability
- Chemical corrosion resistance
- Long service life
