Abstract

Phase equilibria in the sections of the Ca(NO₃)₂–CO(NH₂)₂–H₂O system and the deicing properties of calcium nitrate and carbamide mixtures with a ratio between the components ranging from 90 : 10 to 40 : 60 have been studied. Eutectic temperatures with ice, melting ability at a temperature of –5 and ‒10°C, and the character of interaction with water (the occurrence of an endothermic or exothermic effect) have been determined for these mixtures. Mixtures having the best anti-icing properties are revealed.

Ca(NO3)2–CO(NH2)2–H2O 系统各部分的相平衡和硝酸盐–尿素混合物的除冰性能

摘要

Ca(NO ₃ ) ₂ –CO(NH ₂ ) ₂ –H ₂ O 系统部分的相平衡以及硝酸钙和尿素混合物的除冰性能，组分之间的比例为 90 : 10 到 40 : 60已经研究过了。已确定这些混合物的与冰的共晶温度、在 –5 和 –10°C 温度下的熔化能力以及与水相互作用的特征（吸热或放热效应的发生）。揭示了具有最佳抗结冰性能的混合物。
