磷酸盐结合砖 phosphate-bound bricks search
The high temperature volume stability of phosphate-bound bricks is lower than that of ordinary burned bricks; the normal temperature and pressure resistance strength of phosphate-bound unburned bricks is higher than that of ordinary burned bricks, and the stomatal rate of phosphate-bound bricks is lower.
The solution of phosphate binding does not burn high aluminum bricks.When the heat treatment temperature did not reach 500℃, the binder generated AlH2P3O10, which was changed to AlH2P3O10 · 2H2O, which was the aluminum phosphate sample after 300 to 400℃ after the heat treatment of 300.
The effect of heat treatment temperature and atmosphere on the pressure resistance of high-burning aluminum bricks with phosphate binding shows that the pressure resistance of 800℃.The 1100℃ heat treatment is significantly better than the 600℃ heat treatment. The heat treatment temperature above the 1200 loses the superiority of no burning bricks like burning into high aluminum brick.
Phosphate binding brick, while introducing chromium zirconium elements, may produce uncertain chemical changes in different temperature states, which has a great impact on the production molding rate, overall strength, and stable stability of thermal shock.
