我们的日常生活离不开各种食品，但是食品的保质期是有限的，特别是在高温情况下，很容易出现变质的情况，而这时，就需要使用食品冷库，食品冷库担负着食品的储存、预冷、生产加工等工作，因此对于食品冷库的建造要求严格。而食品冷库隔热材料的选择，关系着冷库后期运转的方方面面，那么食品冷库的隔热材料有哪些呢？
Our daily life cannot do without all kinds of food, but the food shelf life is limited, especially under the condition of high temperature, it is prone to deterioration of the situation, and then, you need to use the food storage, food storage bears a food store, precooling, production and processing and so on, so for the construction of food storage strict requirements. And the choice of food cold storage insulation materials, the relationship between the late operation of the cold storage, then the food cold storage heat insulation materials have?
1、挤塑聚苯乙烯泡沫塑料
1, extruded polystyrene foam
挤塑聚苯乙烯泡沫塑料被认作是一种较为理想的冷库工程隔热材料，因其具有较强的抗湿性、抗压性、抗水蒸汽渗透性，在冷库地平保温的使用中也相当高，同时价格适中，对于食品冷库而言，是一款性价比非常高的冷库保温材料。
Extruded polystyrene foam is considered an ideal cold storage insulation material, because of its strong moisture resistance, compression resistance, water vapor permeability, in the use of cold insulation in the horizon is quite high, and moderate prices for food storage, cold storage is a very high cost of the insulation material.
2、聚氨酯泡沫塑料
2, polyurethane foam plastics
聚氨酯是最为常见的一种冷库隔热保温材料，分聚氨酯夹芯保温板和聚氨酯喷涂两种。聚氨酯泡沫保温材料相比其他类型的保温材料的最大优点是导热系数小、吸水率低、压缩强度大、耐久性高等，非常符合食品冷库隔热材料的各项要求。同时聚氨酯泡沫也是浩爽制冷各类冷库工程中使用最多的一种保温材料。唯一的缺点是聚氨酯泡沫价格较高，但却是最优质的冷库保温材料。
Polyurethane is one of the most common cold storage heat insulation materials, polyurethane sandwich insulation board and polyurethane spraying two. The biggest advantage of polyurethane foam insulation materials than other types of insulation material is small thermal conductivity, low water absorption and high compressive strength, high durability, is consistent with the requirements of the food cold storage insulation materials. At the same time, the polyurethane foam is one of the most widely used heat insulation materials in all kinds of cold storage projects. The only drawback is the high price of polyurethane foam, but it is the best quality of cold storage insulation materials.
3、聚苯乙烯泡沫塑料
3, polystyrene foam plastics
聚苯乙烯泡沫是一种价格比较便宜的冷库保温材料，但导热系数较低，吸水性较高，可以适用于一些温度较高的冷库中。
Polystyrene foam is a kind of cold storage heat preservation material with low price, but its thermal conductivity is lower and its water absorption is higher.
4、聚氯乙烯泡沫塑料
4, PVC foam plastic
是一种保温隔热防震隔声的新型材料，具有微细的独立气泡结构、热导率和密度小的特点。耐水性、抗蒸汽渗透、耐低温、阻燃、抗老化等各项性能指标均佳。按照发泡膨胀率不同，PEF有15倍、30倍和45倍三个系列。45倍发泡体用于库房墙面隔热层，30倍发泡体用于库房地面隔热层，15倍发泡体用于表面彩板保护层。
Is a kind of new material with heat insulation and shock proof and sound insulation. It has the characteristics of fine independent bubble structure, thermal conductivity and small density. Water resistance, resistance to steam penetration, low temperature resistance, flame retardant, anti-aging and other performance indicators are better. In accordance with the expansion rate of foam, PEF has 15 times, 30 times and 45 times the three series. 45 times the foam body is used for the thermal insulation layer of the warehouse, 30 times the foaming body is used for the thermal insulation layer of the storehouse, and the 15 times the foaming body is used for the surface color plate protection layer.
对于食品冷库的隔热材料有哪些今天就分享到这里， 冷库隔热材料的首要性能就是保温性能的好坏，同时作为食品冷库的隔热材料，还应具备耐腐蚀性、密封性、防潮性、抗寒性、坚固性等特性。
For insulation food storage what today is here to share, the primary performance of cold storage insulation material is heat preservation performance, at the same time as the insulation material of food storage, should also have the corrosion resistance, moisture resistance, cold resistance, strong sealing performance.
