Seeking help with PET recycling and granulation
Thread Content
During PET extrusion granulation, the extruded fluid breaks up and becomes discontinuous, which prevents successful filament drawing. I would like to ask everyone: **what is the reason for this, and are there any solutions?**
There is gas in the melt pipe. 1. The gas in the pipeline has not been completely removed. 2. Melt degradation also produces gas; check whether the reaction is excessive or if there are dead zones in the pipes
