【摘要】 对比了在远洋船舶冷库中广泛使用的岩棉和聚氨酯泡沫塑料作为绝热材料的优缺点。以硬质聚氨酯泡沫塑料作为装配式冷库的绝热材料,讨论了不同施工工艺的优缺点。在现代化造船产业中,聚氨酯泡沫塑料成为了一种可以提升船舶预安装比重、性价比高、施工周期短、适应性强的材料,在造船产业中有着广阔的应用前景。更多还原

【Abstract】 This paper compared advantages and disadvantages of rock wool and polyurethane foam as thermal insulation materials widely used in the cold storages of oceangoing ships. It also discussed the merits and faults of different construction technology of rigid polyurethane foam as a thermal insulation material for prefabricated cold storage. In the modern shipbuilding industry, polyurethane foam becomes one kind of material which can improve the proportion of the ship’ s preinstallation and has features of cost-effectiveness,short construction period and strong adaptability,so it has a broad application prospect in the shipbuilding industry.更多还原
