我們的日常生活離不開各種食品，但是食品的保質期是有限的，特別是在高溫情況下，很容易出現變質的情況，而這時，就需要使用食品冷庫，食品冷庫擔負著食品的儲存、預冷、生產加工等工作，因此對于食品冷庫的建造要求嚴格。而食品冷庫隔熱材料的選擇，關系著冷庫后期運轉的方方面面，那么食品冷庫的隔熱材料有哪些呢？
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、擠塑聚苯乙烯泡沫塑料
1, extruded polystyrene foam
擠塑聚苯乙烯泡沫塑料被認作是一種較為理想的冷庫工程隔熱材料，因其具有較強的抗濕性、抗壓性、抗水蒸汽滲透性，在冷庫地平保溫的使用中也相當高，同時價格適中，對于食品冷庫而言，是一款性價比非常高的冷庫保溫材料。
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
聚氨酯是最為常見的一種冷庫隔熱保溫材料，分聚氨酯夾芯保溫板和聚氨酯噴涂兩種。聚氨酯泡沫保溫材料相比其他類型的保溫材料的最大優點是導熱系數小、吸水率低、壓縮強度大、耐久性高等，非常符合食品冷庫隔熱材料的各項要求。同時聚氨酯泡沫也是浩爽制冷各類冷庫工程中使用最多的一種保溫材料。唯一的缺點是聚氨酯泡沫價格較高，但卻是最優質的冷庫保溫材料。
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
聚苯乙烯泡沫是一種價格比較便宜的冷庫保溫材料，但導熱系數較低，吸水性較高，可以適用于一些溫度較高的冷庫中。
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
是一種保溫隔熱防震隔聲的新型材料，具有微細的獨立氣泡結構、熱導率和密度小的特點。耐水性、抗蒸汽滲透、耐低溫、阻燃、抗老化等各項性能指標均佳。按照發泡膨脹率不同，PEF有15倍、30倍和45倍三個系列。45倍發泡體用于庫房墻面隔熱層，30倍發泡體用于庫房地面隔熱層，15倍發泡體用于表面彩板保護層。
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.
對于食品冷庫的隔熱材料有哪些今天就分享到這里， 冷庫隔熱材料的首要性能就是保溫性能的好壞，同時作為食品冷庫的隔熱材料，還應具備耐腐蝕性、密封性、防潮性、抗寒性、堅固性等特性。
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.
