次氧化锌粉制取一水硫酸锌的研究与实践

The experiment results in the paper show that quantitative additive putting in the hydration water can check the iron ion content of the monohydrate sodium carbonate,to attain the goal of improving the whiteness of dense soda ash,in the solid hydrated technological process.

在固相水合法生产重质纯碱工艺中 ,在水合水内加入一定量的添加剂 ,可抑制一水碱中Fe份对重灰白度的影响 ,从而达到提高重灰白度的目的。

The influence of drying condition of monohydrate sodium carbonate on the whiteness of dense soda ash is discussed in this paper.

主要研究一水碱干燥条件对重质纯碱白度的影响规律。
