前言天然气液化、乙烯分离、空分等工程的经济效果直接和低温绝热技术相关。常压低温绝热方式仍然被普遍地应用,这应归功于新型绝热材料和新式绝热方式的研究成果。十几年来泡沫玻璃和硬聚胺酯泡沫塑料被认为是良好的常压低温绝热材料,以它们为基料的各种绝热方式在工程上也不断出现

Preface Natural gas liquefaction, ethylene separation, air separation and other economic effects of the project directly and low temperature insulation technology. Atmospheric pressure and low temperature insulation methods are still widely used, which should be attributed to the research results of new insulation materials and new insulation methods. More than a decade of foam glass and rigid polyurethane foam are considered good atmospheric pressure and low temperature insulation materials, and the various insulation methods based on them are constantly emerging in engineering
