Desiccant soda lime production methods : CaCO3 at about 1000 ℃ to burn 3-4h, is processed into quicklime obtained powder, and concentrated solution of NaOH, the role of iron in the 200-250 ℃ evaporated by the heating system of container Obtained solid mixture that is desiccant soda lime. In this process, the lime in the alkaline solution is completely generated Ca(OH) 2, and in 200-250 ℃ under the conditions of dry, far from Ca(OH)2 decomposition temperature of [Ca(OH)2 The thermal decomposition temperature is 580 ℃].
The actual composition of the desiccant soda lime is: Ca (OH)2 about 83%, NaOH about 5%, water about 12%.
