Problems solved by technology
At present, domestic recycled plastics have been used on a large scale, but there are no corresponding testing standards and technical standards in China to regulate and characterize the product
Due to the complexity of recycled plastic recycling production, there may be problems such as large impurities in recycled plastic products and product quality defects.
The existence of these problems has greatly restricted the use of recycled plastic products and affected the confidence of users

The invention discloses an automatic intelligent judgment method and device for recycled plastics. The automatic intelligent judgment method comprises the following steps that infrared spectrum test,thermogravimetric curve test and DSC test are correspondingly carried out on standard samples of newly produced plastics and the recycled plastics of a first type, and the infrared spectrum curve, thermogravimetric curve and DSC curve are analyzed to correspondingly obtain a plurality of characteristics of the infrared spectrum curve, thermogravimetric curve and DSC curve of the standard samples of the newly produced plastics and the recycled plastics of the first type; infrared spectrum test is carried out on a sample to be judged of the first type, and the infrared spectrum curve is analyzedto obtain a plurality of characteristics of the infrared spectrum curve; whether the infrared spectrum curve aiming at the standard sample of the newly produced plastics of the first type has sufficient degree of distinction or not with the infrared spectrum curve aiming at the standard sample of the recycled plastics of the first type is determined; and if the sufficient degree of distinction exists, specified operation is performed. The automatic intelligent judgment method has high judgment efficiency and accuracy.
Description
technical field [0001] The invention relates to the field of intelligent devices for plastic production, in particular to an automatic intelligent judgment method and system for recycled plastics. Background technique [0002] Parallel with the development of the plastics industry is the only way for the recycled plastics industry to be standardized and high-tech. Harmful substances that may endanger the environment and human health may exist in recycled plastics. At present, domestic recycled plastics have been used on a large scale, but there are no corresponding testing standards and technical standards in China to regulate and characterize the product. Due to the complexity of recycling and production of recycled plastics, there may be large impurities in recycled plastic products and defects in product quality. The existence of these problems has caused the use of recycled plastic products to be greatly restricted and affects the confidence of users. The European Uni...
