How to identify the grade and quality of plastic recycled materials
1. Surface finish is an important indicator to measure the quality grade of various recycled materials. Smooth surface lubrication of high quality recycled materials 2. Transparency is an important indicator to measure the quality grade of medium and high grade recycled materials. Transparent materials, good quality 3. Uniformity and consistency of color is an important indicator to measure the quality grade of colored recycled materials. (white, milky white, yellow, blue, black, etc.) 4. Particle compactness is an important aspect of testing the level of regeneration technology Poor plasticization, loose particles 5. See if the recycled particles are floating in water for testing the filling content of PP.PE particles. For recycled materials, different recycled materials have different uses, because it is not easy to formulate uniform standards to fully meet the user's process requirements!
