苛性石灰

The recovery of alumina in the high mole ratio aluminate solution was studied.

对加入石灰后的高苛性比铝酸钠溶液中氧化铝的回收进行了研究。

Pulp mills can use partial borate autocausticizing to increase their causticizing capacity or reduce energy intensity by adding sodium metaborate to the liquor cycle which drives autocausticizing reactions in the recovery boiler and forms sodium hydroxide in the smelt dissolving tank without the use of lime or additional causticizing processes.

纸浆厂可以利用硼酸盐自动苛性微粒来提高他们的苛性化能力或是通过在循环液中增加驱动回收炉中的自动苛性化反应和在冶炼溶解池中形成氢氧化钠而不使用石灰和额外的苛性处理的硼酸钠来减少能源的强度。

The thermodynamic calculation results indicated that the formation of calcium aluminate hydrate from aluminate solution with CaO is easier than that with Ca2, and the value of αk is great at low temperature; the temperature rise leads to the reduction of stability of calcium aluminate hydrate in the aluminate solution, and it can be decomposed at high temperature, which can both substitute for Ca2 and recover alumina in the process of Bayer.

热力学计算结果表明，氧化钙较氢氧化钙更容易使铝酸钠溶液中的铝酸根离子转化为水合铝酸钙，使铝酸钠溶液的平衡苛性比能达到很高的值；水合铝酸钙随着温度的升高，稳定性降低，因而能在拜尔法高温溶出过程中分解以代替石灰，并回收其中的氧化铝。

" Adding water to lime yields calcium hydroxide (slaked lime, calcium hydrate, hydrated lime, or caustic lime), which is used in mortar, plaster s, cements, whitewash, hide dehairing, and water softening and purification and as a source of other calcium salts."
