How to choose the tray

Depending on the use of the environment, choose different materials tray. Temperature conditions. Different temperature directly influence the choice of pallet manufacturing materials. This is because the tray of different materials have to play their normal temperature range performance. Such as plastic pallets in temperature between + 40 ~ -25 ℃. Tray certain materials because of strong moisture absorption, such as wooden pallets can not be used in humid environments, otherwise it will directly affect the service life. The use of environmental cleanliness. To consider the use of environmental pollution on the pallet. A high degree of contamination of the environment to be sure to selec stain resistance, easy to clean tray. Such as plastic pallets, composite wood pallets and the like. Goods carried by the special requirements of pallet material. Sometimes the cargo pallet load of goods carried by corrosive or tray requires a higher level of cleanliness, we must choose the corrosion resistance of the plastic tray, tray or wood composite.

1, on the choice of materials:
Depending on the use of the environment, choose different materials tray. Different temperature directly influence the choice of pallet manufacturing materials. This is because the tray of different materials have to play their normal temperature range performance. Such as plastic pallets in temperature + humidity of between 40 ~ -25 ℃. Tray certain materials because of strong moisture absorption, such as wooden pallets can not be used in humid environments, otherwise it will directly affect the service life. The use of environmental cleanliness. To consider the use of environmental pollution on the pallet. A high degree of contamination of the environment to be sure to selec stain resistance, easy to clean tray. Such as plastic pallets, composite wood pallets and the like. Goods carried by the special requirements of pallet material. Sometimes the cargo pallet load of goods carried by corrosive or tray requires a higher level of cleanliness, we must choose the corrosion resistance of the plastic tray, tray or wood composite.

2, depending on the application options:
If the pallet load of goods for export. Since many countries importing goods for packaging materials used in fumigation insecticide-treated, equivalent to an increase of exports into the tray for export should try to choose disposable plastic trays or simple fumigation tray composites. Whether pallets on the shelves. For shelf stacking tray should be selected rigid, easily deformed, dynamic load large tray; such as steel and wood pallets harder hardwood wooden pallets.

3, pallet size selection:
Current national standard pallet specifications There are four, namely, 1200mm × 1000mm, × 200mm × 800mm, 1140mm × 1140mm and 1219mm × 1016mm. To make the tray has versatility for future use, should be used as much as possible these types of trays, so to facilitate the exchange and use of the future of the tray. Of course, as has long been the industry formed its own inherent Packing size would tray size specifications some specific different requirements, is understandable, but in the long perspective, or should choose GB size. To consider the means of transport and transport equipment size specifications. Pallet size should be appropriate just to meet transportation dimensions, this can increase sufficiently rational use of space transport, save transportation costs, in particular, consider the size of the box and container transport trucks. In addition to considering the format and size, but also consider the size of the warehouse, the size of each cargo grid; consider pallet loads of goods packaging specifications, selec the appropriate tray according to the size of pallet loads of goods packaging specifications, can maximize the use of the surface area of ​​the pallet. Consider the use of the tray section. Pallet load cargo flows directly affect the choice of pallet sizes. Flights to Europe usually cargo trays to choose 1200mm × 1000mm, the cargo destined for Japan to choose 1100mm × 1100mm tray.

4. selec the tray structure:
Tray structure directly affects the efficiency of the tray, a suitable structure can give full play to the characteristics of high efficiency operation of the truck. Tray use as ground floor slab, that tray after loading the cargo does not move, just to play the role of water moisture, choose a simple structure, low cost carrier, such as simple plastic tray, it should be noted static load tray, with in transport, handling, loading and unloading pallets, to selec high-intensity, dynamic load large tray. This type of trays due to repeated use, and you want to use with forklifts, pallet and therefore higher strength requirements, which requires the tray structure is "field" line or the "plain" word lines. Depending on whether you want to load cargo pallet stacking after determining the choice of single-sided or double-sided tray. Since only a single-sided pallet bearing surface, not suitable for stacking, or likely to cause damage to the underlying goods, so after a cargo stacking needs, we must try to selec duplex tray. If the tray is used in three-dimensional library shelves, but also consider the structure of the tray is suitable code on the shelves. Since usually only inserted and removed from the shelves of goods in both directions, so for pallet racking should be used as much as possible on all sides of the tray into the fork, it is easy to take the fork truck goods, improve work efficiency. Such a structure usually seleced tray swastika row.

5, plastic pallet identification skills
As different varieties of plastic, respectively, so that separation and recovery, one must master the knowledge of identification of different plastics, plastic simple identification method described below:
The appearance of plastic identification: by observing the appearance of plastic, plastic products may be initially identified belongs to categories: thermoplastics, thermosetting plastics or elastomers. Generally thermoplastics have crystalline and amorphous categories. Crystalline plastic is translucent, milky or opaque, and only state in the film was transparent, hardness from soft to horny. Generally colorless amorphous, when no additive is completely transparent to the hardness of the hard rubber-like keratinocytes (case often with plasticizers and other additives). Thermosetting plastics generally contain filler without clear transparent material, such as transparent when no filler. Elastomer with rubber-like feel, there is a certain elongation.

Identification of plastic heating: the heating characteristics of the three types of plastics also vary by heating method can be identified. Becomes heated and softened thermoplastic, meltable, molten transparent and often pulled from the wire to melt, are usually easy to heat. Thermosetting plastic material is heated to a former chemical decomposition, maintaining its original hardness does not soften, size relatively stable, the decomposition temperature carbonization. When the elastomer is heated until the chemical decomposition temperature, no flow occurs, the decomposition temperature of the material to decompose carbonization.
