Refractories Co., Ltd., Zhengzhou City shangzhuang learned alumina brick surface network of cracks more products produced in the brick yard brick surface cracks. It can be inferred that when the kiln excess air coefficient, or produce a reducing atmosphere, due to the small cracks between the blocks, carbon monoxide (CO) is easy to stay in these places, so that the products of iron oxide (Fe2O3) is reduced to ferrous oxide ( FeO); for the passage of clay brick surface insulation tiles, airflow is smoother, it is not affected by changes in climate affect clay insulating bricks, did not produce a network of cracks. Of particular note is the clay insulation bricks in the firing process should try to avoid frequent changes in the nature of the combustion atmosphere. Therefore, the role of this change will alternate surface damage. Refractories Co., Ltd., Zhengzhou City shangzhuang tell everyone to use burnout Additions Production of Light aluminum bricks advantages are: pellets substantially non-absorbent, so that after forming the embryo moisture content in small, brick culture during the drying process are not deformed, so that the production of the finished product size is relatively uniform, accurate, eliminating the step of grinding modified clay insulating bricks, you can achieve the required size. Meanwhile, in order to help deliver the brick moisture and prevent cracking of adobe bricks caused, we add some wood and foam beads mixed.
