磷酸盐结合砖 phosphate-bound bricks search

磷酸盐结合砖高温体积稳定性低于普通烧成砖；磷酸盐结合的不烧砖的常温耐压强度高于普通烧成砖；磷酸盐结合砖的显气孔率较低。

磷酸盐结合不烧高铝砖的潮解问题。当热处理温度没有达到500℃时，结合剂生成AlH2P3O10，易吸湿转变成AlH2P3O10·2H2O，这正是磷酸铝试样经过300~400℃热处理后，露置在大气中发生溃散粉化。

热处理温度和气氛对磷酸盐结合的不烧高铝砖耐压强的影响，结果表明，还原气氛对耐压强度没有影响；随着温度升高，耐压强度升高，似乎800℃略有下降现象。1100℃热处理明显好于600℃热处理的，热处理温度超过1200就像烧成高铝砖一样失去了不烧砖的优越性。

磷酸盐结合砖，引入铬锆元素的同时，在不同温度状态下，可能产生不确定化学变化，对磷酸盐砖的生产成型率，整体强度，以及热震稳定行产生较大影响。

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.
