一些冷庫中的貨物堆放和存放都會適用到塑料托盤，廠家在選用的時候不知道選用什么樣的，接下來塑料托盤廠家為你介紹一下。
Some cold storage of goods stacking and storage will be applied to the plastic pallet, manufacturers do not know what to choose when choosing, the next plastic pallet manufacturers to introduce you.
正負40℃之間時，不建議用聚丙烯材質的。這種材料不能抗低溫。如果您在冷庫中托盤需要上貨架的話,好選用雙面托盤，貨物較輕的話可以選擇田字的或者川字網格托盤。
When the temperature is between plus and minus 40 ℃, polypropylene is not recommended. This material is not resistant to low temperature. If you need to put the pallets on the shelves in the cold storage, you can choose double-sided pallets. If the goods are lighter, you can choose Tian or Chuan grid pallets.
另：在低溫環(huán)境下使用，實踐證明，改性聚丙烯可以完全勝任。改性聚丙烯為聚乙烯與聚丙烯的高溫不完全聚合產物。他兼具了聚丙烯的韌性，聚乙烯的耐低溫，物理性質穩(wěn)定，抗磨耐摔。大型化工企業(yè)，低溫冷庫等環(huán)境一般建議使用該種材料。
In addition, it can be used in low emperature environment, and the practice shows that the modified polypropylene can be fully competent. The modified polypropylene is the product of high temperature incomplete polymerization of polyethylene and polypropylene. It has the toughness of polypropylene, low temperature resistance of polyethylene, stable physical properties, wear resistance and drop resistance. It is generally recommended to use this kind of material in large chemical enterprises and low temperature cold storage.
可以采用低壓高密度聚乙烯生產的塑料托盤，純原料生產的塑料托盤可以耐受零下30℃的低溫。采用擠出--吹塑一次成型的高強度吹塑托盤，一般均會采用HMWHDPE塑料進行吹塑成型，其重均分子量達到35~40萬左右;這種塑料原料具有對環(huán)境溫度的超.強適應能力，可以在-40~40℃環(huán)境中穩(wěn)定使用，是需要高強度使用環(huán)境的首.選塑料托盤，由于這種高強度吹塑托盤選擇的塑料原料成本高，加工過程技術難度較高，產品的使用壽命特別長，可以達到5~10年。雖然一次購買時會較高，但是綜合使用成本確是較低的。需要高強度使用時，可以選擇這種高強度的吹塑托盤。
It can be made of low-pressure high-density polyethylene and pure raw materials, which can withstand the low temperature of - 30 ℃. Hmwhdpe plastic is usually used for blow molding of high strength blow molding tray with extrusion blow molding, and its weight average molecular weight is about 350000 ~ 400000; This kind of plastic material has super strong adaptability to the ambient temperature, and can be used stably in - 40 ~ 40 ℃ environment. It is the first choice for high-strength environment. Because of the high cost of the plastic material selected for this kind of high-strength blow molding tray, the processing technology is difficult, and the service life of the product is particularly long, which can reach 5 ~ 10 years. Although the price of a purchase will be higher, but the comprehensive use cost is lower. When high strength is needed, the blow molding tray with high strength can be selected.
