Ordinary plastic tray detection method is divided into two: one is plastic tray simple identification method, the other is the appearance of the plastic tray identification, the following were introduced to these two common detection methods.[url=http://plasticpalletforsale.com/plastic-pallet/3099.html]Egg Tray With Motor Of WQ 154[/url] First, a simple plastic tray identification method In the method using a variety of plastics recycling of waste plastics before recycling, mostly plastic needs to be sorted. As the plastic consumption channels are many and complex, and some post-consumer plastic and difficult to distinguish by its simple appearance, therefore, desirable to indicate the variety of materials in plastics. China to the American Plastics Association (SPE) to propose and implement a variety of materials developed marked GB / T16288-1996 "plastic packaging recycling logo", although the mark can be used to facilitate the sorting method, but China still has many unmarked plastic products, to sorting difficult, 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: Second, the appearance of discrimination plastic tray 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.[url=http://plasticpalletforsale.com/plastic-pallet/1664.html]Wooden Pallets Prices[/url] Plastic pallet according to the structure can be divided into: Tian-shaped grid of plastic pallets, plastic pallets Sichuan font, double-sided plastic mesh tray, double-sided flat plastic tray, plastic tray nine foot grid, nine feet flat plastic tray, moisture plate plastic trays, plastic composite plate tray disposable plastic pallets for export.
