1. Surface finish is an important indicator to measure the quality grade of various recycled materials: the surface of high-quality recycled materials is smooth and lubricated.
2, transparency is an important indicator to measure the quality grade of medium and high-grade recycled materials: the material with transparency, the quality is good.
3, the uniformity and consistency of color is an important indicator to measure the quality grade of colored recycled materials: white, milky white, yellow, blue, black and other colors.
4. Particle compactness is an important aspect of testing the level of regeneration technology: poor plasticization and loose particles.
5. See if the regenerated particles are floating and water for testing the content of filler material of PP and 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.
