How to improve the transparency of PP recycled particles?

The variety of plastic waste is complex and it is difficult to establish uniform quality standards. So far, PP recycled pellets have neither corporate standards nor national or international standards. It can be affirmed that as long as the recycled plastics are classified, cleaned and pulverized, the recycled PP particles have certain market value, and there is no pass or fail.

In order to obtain PP recycled particles with excellent transparency, it is necessary to use higher grade scraps for reprocessing raw tea. To measure the transparency of PP recycled particles, it is necessary to investigate the transmittance, haze, refractive index birefringence and Standard basis such as dispersion.

The transparency of the PP recycled particles can be improved by reducing the crystallinity, controlling the clean quality, increasing the refractive index, and reducing the original principles and methods such as birefringence. Adding improved transparency of the plastic, a nucleating agent can be added, which is the most effective way to increase the transmittance of the transparent resin, which can promote the crystallization of small molecular substances. It can function as a nucleus in the resin. Blending improves the transparency of plastics by adding other resins to the transparent resin to improve transparency. The two-way stretching improves the transparency of the plastic, and can break the original crystal particles in the product to make the crystal size smaller, and achieve the purpose of improving the light transmittance. It can be seen that there are certain differences in the improvement methods of the transparency of different kinds of recycled materials. In actual operation, only the correct principles and conditions can be used to carry out standardized and orderly production and processing.
