纯碱碳酸钠用途:
The manufacture of glass is one of the most important uses of sodium carbonate.When it is combined with silica(SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures,then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
玻璃的制造是碳酸钠重要的用途之一。当它与二氧化硅(SiO2)和碳酸钙(CaCO3)结合并加热到很高的温度时,然后迅速冷却,玻璃就产生了。这种玻璃被称为“碱石灰玻璃”。

联碱法以食22盐、氨及合成氨工业副产的二氧化碳为原料,轻质纯碱重质纯碱,同时生产纯碱及氯化铵,即联合产纯碱与氯化铵,简称'联合制碱'或称'联碱'主要反应为: NaCl+NH3+H2O+CO2= NaHCO3 ↓+NH4Cl NaHCO3 = Na2CO3+CO2↑+H2O↑ 根据加入原料的次数及析出氯化铵温度的不同,联合制碱有多种工艺流程。我国多采用:一次碳化,两次吸氨,一次加盐,低温析铵流程。
