一些冷库中的货物堆放和存放都会适用到塑料托盘，厂家在选用的时候不知道选用什么样的，接下来塑料托盘厂家为你介绍一下。
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.
正负40℃之间时，不建议用聚丙烯材质的。这种材料不能抗低温。如果您在冷库中托盘需要上货架的话,好选用双面托盘，货物较轻的话可以选择田字的或者川字网格托盘。
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：在低温环境下使用，实践证明，改性聚丙烯可以完全胜任。改性聚丙烯为聚乙烯与聚丙烯的高温不完全聚合产物。他兼具了聚丙烯的韧性，聚乙烯的耐低温，物理性质稳定，抗磨耐摔。大型化工企业，低温冷库等环境一般建议使用该种材料。
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.
可以采用低压高密度聚乙烯生产的塑料托盘，纯原料生产的塑料托盘可以耐受零下30℃的低温。采用挤出--吹塑一次成型的高强度吹塑托盘，一般均会采用HMWHDPE塑料进行吹塑成型，其重均分子量达到35~40万左右;这种塑料原料具有对环境温度的超.强适应能力，可以在-40~40℃环境中稳定使用，是需要高强度使用环境的首.选塑料托盘，由于这种高强度吹塑托盘选择的塑料原料成本高，加工过程技术难度较高，产品的使用寿命特别长，可以达到5~10年。虽然一次购买时会较高，但是综合使用成本确是较低的。需要高强度使用时，可以选择这种高强度的吹塑托盘。
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.
