Mullite Andalusite Brick and Andalusite high alumina brick each has their own advantages. Although mullite bricks and high alumina bricks have the main components of alumina, the crystals of the two are different.
When the red pillars are heated to 1300℃, it will become mullite stone has the characteristics of resistance to cold and cold, and the advantages of strong impact resistance and high load transformation points. Mullite itself was swollen and low during the conversion process. There is no need to burn in red pillar stones, and it can be directly added to the fired or unpaid Mullite brick and high alumina brick. The red pillars have the advantages of resistance to degeneration. During use, impurities can cause premature softening of refractory bricks and have a great impact on creep. Therefore, a certain percentage of red pillar stones are added to mullite bricks or high alumina bricks. Make it high temperature, emergency and cold.
Andalusite high aluminum bricks are based on Andalusite as the main raw material, adding aluminum alum soil, and fired by high -voltage molding, drying, and 1500℃. The characteristic of Andalusite high aluminum bricks is that the temperature resistance is high, the softness temperature is high, the peristalsis is low at high temperature, and the high temperature volume is stable and stable. The fire resistance of red pillar stone is 1830℃. The chemical corrosion resistance and adding red pillar stones to the high alumina refractory brick can make the high alumina brick with abrasion resistance and higher load softening temperature and better anti -emergency heat heat performance. At high temperature, you can cause tight brick seams to increase the overall density of high alumina brick masonry, thereby increasing the penetration of residue.
Mullite Andalusite Brick is a kind of refractory tiles made of red pillar stones and mullite stone. This brick has good antioxidity, strong fire resistance, high pressure resistance, low proportion, and anti -peeling performance. Good, high temperature resistance strength, high service life.
In short, there is the same point, and there is a big difference between Mullite andalusite brick and andalusite high aluminum bricks. Mullite Andalusite Bricks are higher than red pillars high aluminum bricks, while red pillars high alumina brick high temperature resistance is strong. The mullite andalusite bricks are flexible and stronger.
