近来,上海沪东造船厂将国产不燃性保温材料泡沫玻璃和岩棉制品应用于船舶的冷藏系统,进一步增强了船舶的防火能力,并在设计上达到了当前最高船规的要求。目前船舶的冷藏系统普遍采用的保温材料主要是聚苯乙烯泡沫塑料、聚氨酯泡沫塑料以及灌注喷涂料。这类材料虽然热导率及密度小,可以减薄使用厚度,吸湿性和吸水性也比较小且能长期保持良好的保冷效果,但由于它们均属于有机材料,因而具有可燃性,即使配入各种阻燃、难燃的助剂,一遇 Recently, Shanghai Hudong Shipyard has applied domestic non-combustible insulating material foam glass and rock wool products to ships’ refrigeration systems, further enhancing the ship’s fire protection capabilities and achieving the current highest ship regulations in design. At present, the insulation materials commonly used in ship refrigeration systems are mainly polystyrene foam, polyurethane foam, and spray-in spray paint. Although these materials have a small thermal conductivity and density, they can be used in thinner thicknesses, have less hygroscopicity and water absorption, and can maintain good cold-keeping effects for a long period of time. However, because they are all organic materials, they are flammable even when formulated. Various flame-retardant and flame-retardant additives
