Shandong Qingdao inspection and Quarantine Bureau detected that the imported metal coated waste plastics exceeded the standard

January 23, 2013

[China paint information] in 2012, Shandong Qingdao inspection and Quarantine Bureau detected a total of 42 batches and 2060 tons of imported waste materials that were unqualified in environmental protection projects. Among them, there are 7 batches of waste plastics with metal coating exceeding the standard, weighing 236.22 tons, accounting for one sixth and one tenth respectively. Many customers consult the sleeve connection deformation detector. For such goods, Qingdao Bureau has issued the inspection certificate and disposal notice, and handed them over to the Customs for return processing

metal coatings mainly contain two kinds of pollutants such as aluminum, copper and zinc, and some pull nickel, chromium, lead and other first-class pollutants. Generally, metal coatings are sprayed, electroplated, vacuum sputtered, bonded and hot pressed. At present, the reuse of most metal coated waste plastics needs to be removed by chemical methods. Most of the coated metals are changed into corresponding metals to create the industrial chain of "magnetic materials and key supporting materials - magnet components - Special Electromechanical". The ions are dissolved in the cleaning water, which is very easy to cause serious pollution of the water system. In particular, class I pollutants have cumulative hazards, which will cause long-term and large-scale pollution through the food chain, with great environmental risks

in this regard, the inspection and Quarantine Department reminded relevant enterprises that before signing purchase contracts with foreign suppliers, they should strictly follow the standard requirements of limiting the weight of plastic films and plastic products coated with metal layers to 5 ‰ of the total weight of goods in the "control standard for environmental protection of imported solid wastes that can be used as raw materials" and ensure the quality of the source
