Abstract

Phase equilibria at temperatures of 0 to –60°C are studied in sections of the urea–propylene glycol–water system with urea to propylene glycol ratios of 3 : 1 to 1 : 3. It is found that the introduction of propylene glycol into the urea–water system makes it possible to obtain anti-icing compositions that are effective at temperatures below –11°C, down to temperatures of –35 to –40°C, with satisfactory melting capacity for ice. The compositions are promising for the development of anti-icing reagents on their basis.

基于尿素和丙二醇的防冰组合物

研究了尿素-丙二醇-水体系中尿素与丙二醇比例为3:1 ~ 1:3的部分在0 ~ -60℃温度下的相平衡。研究发现，在尿素-水系统中引入丙二醇，可以获得在-11°C以下、-35°C至-40°C的温度下有效的防冰组合物，并具有令人满意的融冰能力。在此基础上，该组合物具有开发防冰剂的前景。
