隔热材料的选用必须因地制宜,既要有良好的隔热性能,又要经济实用。
Selection of insulation materials must adjust measures to local conditions, should not only have good heat insulation performance, and economic and practical.
隔热材料分几种类型,一种是加工成固定形状及规格的板块,有固定的长度、宽度和厚度,可根据库体安装的需要选择相应规格的板块,高、中温冷库一般选用10厘米厚的板块,低温库及冻结库一般选用12厘米或15厘米厚的板块;
Insulation several types, one is processed into fixed shape and specifications of the plate, a fixed length, width and thickness, can choose according to the needs of library body installation of corresponding specification plate, high and medium temperature cold storage generally selected 10 centimeters thick plate, low temperature library and freeze library generally selected 12 cm or 15 cm thick plate;
另一种可以用聚氨脂喷涂发泡,把材料直接喷到已经建成的砖或混凝土仓库中,定形后既防潮又隔热。
Another can use spray polyurethane foam, the material directly spray to have been built of brick or concrete warehouse, after setting is moisture-proof and insulation.
隔热材料板块有聚氨脂、聚苯脂等。聚氨脂不吸水,隔热性较好,但成本较高;聚苯脂吸水性强,隔热性较差,但成本较低。
Polyurethane and polystyrene insulation plate fat, etc. Better insulating polyurethane not bibulous, stays, but higher costs; Poor insulating polyphenyl ester water imbibition is strong, stays, but lower cost.
现代冷库的结构正向装配式发展,制成包括防潮层和隔热层的库体构件,做到现场组装,其优点是施工方便、快速,且可移动,但造价比较高。
Made including the development of modern cold storage structure was fabricated, moistureproof layer and insulating layer of library components, field assembly, its advantage is construction convenient, fast, and mobile, but the cost is higher.
