But in recycling, Xuancheng is a company that benefits the environment, by turning materials like used PET plastic into a raw material again. An important part of recycling PET lies in ridding it of carbon black, which can dull the recycled plastic’s usefulness. To clear carbon black properly, we must know about mesh density.
What is Mesh Density?
Mesh density is how many holes are in a screen mesh. In PET recycling, the screen mesh is especially important in eliminating carbon black particles. The diameter of the holes is a measure of what sizes of particles can penetrate them. With a denser metal steel mesh, the holes are smaller and are better at trapping small particles like carbon black.
The Influence of Mesh Density on Recycling
There are several methods in which we take out carbon black in PET recycling, but it depends much on the screens metal mesh density. The bigger carbon black particles, if the mesh density is too low, could slip through and never get trapped, resulting in inferior recycled PET. But when the mesh is too dense, the PET may not easily flow through the screens, which could slow down the recycling process. The right mesh density is very important to maintain recycling efficiency.
Removing Carbon Black
Carbon black is a pigment in a form of a fine powder and is used as a color for plastics, including in PET. When we recycle PET plastic, carbon black has the ability to affect the quality of the recycled material. Xuancheng is able to extract carbon black from the recycled PET by using screens with an appropriate Sintered Filter Mesh density, ensuring that the end product is a premium material.
Selecting an Appropriate Mesh Resolution
The choice of an appropriate mesh density to remove carbon black from PET recycling would be considering what size the carbon black particles are and how good of a quality we want the recycled PET to have. At Xuancheng, the PET material that is being recycled is closely examined to determine the best mesh density for their screens. By using such mesh density, carbon blacks can be effectively eliminated.
The Role of Mesh Density in Recycling
Optimal mesh density is needed to eliminate carbon black in PET recycling. Xuancheng uses advanced recycling machines equipped with screens for optimal mesh consistency. They monitor and adjust the mesh density to ensure the resulting recycled PET is top quality.
