Product Features: (1) is a phosphate binding to plastic, use of high temperature, aluminum phosphate to form a three-dimensional network structure in the heating process, has strong toughness and wear resistance, resistant to high-speed dust particles in the flue gas and materials erosion. (2) has excellent thermal shock resistance. (3) plasticity, easy tamping, smooth surface after construction, not bulging. Using the site: the dense phase circulating fluidized bed boiler furnace zone air distribution plate, water wall extending walls, furnace exit, water and other parts of the cold room, or a more complex structure, can not stand shaped die casting parts. Working temperature about 900 ℃.
