The components of alkaline lime are calcium oxide and sodium hydroxide, both of which belong to alkaline substances. Of course, it can absorb some acidic gases, such as carbon dioxide, sulfur dioxide, hydrogen sulfide, nitrogen dioxide, chlorine and so on.

Generally, 25kg three-layer plastic woven bags are used for soda lime, with plastic woven bags for the inner and outer layers and plastic inner bags for the middle layer. Flake caustic soda is classified as Class 8.2 alkaline corrosive product by Classification and Labeling of Commonly Used Hazardous Chemicals (GB 13690-92), which belongs to Class 8 dangerous goods, and its code is 1823.

Extended data:

Function: Carbonate can be decomposed by heating to produce CO2, only (NH4)2CO3 or NH4HCO3. After the mixed gas produced by decomposition passes through alkali lime, CO2 and H2O are absorbed, and pure NH3 is obtained. (for impurity removal and drying)

Its drying effect can be used to remove impurities in gas, such as NH3(H2O).

Alkaline lime can also remove SO2, H2S, HCl, CO2 and other acidic gases.

Desiccant, as its name implies, is used for drying. Of course, according to the nature of desiccant, the types of substances to be dried are different.
