No matter whether they are native particles or recycled particles, if they contain a large amount of impurities or insufficient purity, it is very easy to encounter quality issues during processing: the existence of impurities may cause surface defects and performance degradation in products, and serious cases may directly result in the entire batch of products being scrapped. Therefore, ensuring the high purity of recycled particles is crucial to safeguarding the value of downstream plastic processing enterprises.

Common Quality Issues of Plastic Particles:

1. Non-uniform color: In the same batch of plastic particles, there are differences in color depth. Some plastic granules have lighter colors, while others have darker colors. This may be due to uneven raw material colors, improper color matching, or unreasonable production process parameters.

2. Foreign impurities: Other substances such as metal, paper, dust, etc., are mixed into the plastic particles. These foreign impurities may be mixed in from the raw materials or may be particles and chips generated by equipment and tool wear during the production process.

3. Non-uniform particle size: Inconsistent sizes of plastic particles, irregular particles, etc., may be caused by the equipment's rotation speed being too fast or too slow, which can affect particle crushing. Additionally, when adjusting equipment parameters, if they are not set correctly according to the characteristics of the raw materials and production requirements, it may result in uneven particle sizes.

4. Extremely small black spots: During the granulation process, due to insufficient cleaning of the equipment before startup, uneven mixing of the reaction vessel mixture, uneven temperature and humidity in the heating or cooling system, etc.

Challenges in Overcoming Micro Quality Inspection:

Common problems such as large color differences, uneven shapes and sizes, and foreign matter mixing can usually be identified by the naked eye or traditional sorting equipment. However, in the case of extremely small black spot particle sorting issues, traditional identification technology is inadequate.

Applications:

1. Sorting of various plastic particles including transparent particles, opaque particles, and semi-transparent particles.

2. Sorting of large particles, irregular particles, mixed-color particles, and dirty particles.

3. Sorting of micro-color difference particles.

4. Support for sorting tiny black spots above 0.1 millimeters.

Core Technology of Independent Research and Development:

1. Micro-difference camera recognition system, ultra-high-definition imaging, ultra-low distortion: By capturing images of plastic particles with an ultra-high-definition camera, tiny differences in color, shape, and texture between particles can be identified. Ultra-low distortion technology ensures the accuracy and authenticity of imaging, avoiding misjudgments caused by image deformation.

2. Stereoscopic focusing sorting technology: The equipment can obtain three-dimensional information of plastic particles, not just two-dimensional images, thereby improving the accuracy of sorting.

3. Multi-dimensional mirror recognition technology: Combining image information from multiple angles and perspectives enables a more comprehensive understanding of particle characteristics by synthesizing information from multiple views.

4. Micro-flaw color recognition technology: This technology is specifically designed to identify tiny defects and color differences in plastic particles.
