Do you know the classification of plastic color selection?

  Plastic is an important organic synthetic polymer material, which is widely used. However, the "white pollution" caused by waste plastics is becoming more and more serious, but plastic recycling and classification has become an important project. There are five kinds of general plastics, namely polyethylene, polypropylene, polyvinyl chloride, polystyrene and acrylonitrile butadiene styrene copolymers.
  The chemical resistance, lightness and robustness of plastics determine their important use in life or industry. With the progress of technology, the recycling of waste plastics is very difficult. How to achieve economic benefits?
  Most plastics need to be classified before recycling waste plastics using various plastic recycling methods. As shown in the figure above, this is a plastic particle produced in the market. In order to classify and recycle these different kinds of plastics, a plastic color sorter was produced.
  Plastic color sorter is a kind of equipment that can automatically separate heterochromatic particles in particle materials by photoelectric detection technology according to different optical properties of materials. The selected materials enter the machinery from the hopper at the upper part. Through the vibration of the vibrator device, the selected materials are transported along the channel and enter the observation area in the selected room through the sensor and the background plate. Under the action of the light source, the system generates an output signal according to the change of light intensity and color, drives the solenoid valve to blow the heterochromatic particles into the waste hopper, and the well selected materials continue to fall into the finished product hopper to achieve the purpose of selection.
