有机物对Na_2SO_4饱和溶解度及液体防冻泵送剂析晶的影响

Influences of organic matter on the performances of the solubility of Na_2SO_4 and the crystallization of liquid anti-freezing pumping agents

文章主要研究了有机物(醇类)在不同温度下对Na2SO4溶解度的影响,仔细分析了有机物(醇类)对液体防冻泵送剂析晶的影响。试验结果表明:有机物(醇类)可以增大硫酸钠在-5～15℃下的溶解度,可以降低液体防冻泵送剂在0～5℃下的析晶量。

The influence of the organic matter （alcohols） on the tsolubility of Sodium sulfate at different temperature is discussed in the paper. The influence of organic material on the crystallization of liquid antifreezing pumping agent is also analyzed. The results show that organic matter （alcohols） can improve the saturated solubility of Sodium sulfate under -5 -15 ℃ and can decrease the crystallization of liquid antifreezing pumping agent under 0-5℃.
