目前我国各种汽车发动机在冬季起动时越来越多地采用防冻液，而且已发展到全年使用。然而目前国内许多防冻液生产厂家的产品还不能满足全年使用的需求，甚至连冬季使用也不能满足，且质量亦难保证，距世界先进水平尚有相当的距离。本文据此提出控制防冻液产品主要性能指标的方法和改进途径，供防冻液生产厂及有关的研究人员参考。 At present, a variety of automobile engines in our country start to use more and more antifreeze in winter, and have been developed to be used throughout the year. However, at present, many antifreeze manufacturers in China are not able to meet the needs of the whole year. Even the use in winter can not be met, and the quality is hard to guarantee. There is still a considerable distance from the world advanced level. Based on this, the paper puts forward the method and the way of improving the main performance indexes of antifreeze products for reference of antifreeze manufacturers and related researchers.
