Abstract

The separation of a three-component polymer mixture, high-density polyethylene/poly(ethylene terephthalate)/poly(vinyl chloride) (HDPE/PET/PVC), was studied on a modernized research station. The separation was performed in two stages. The first stage allowed for the separation of HDPE and the second for the separation of the remaining PET/PVC mixture. The obtained results showed a high efficiency of separation of HDPE from a HDPE/PET/PVC mixture. HDPE was separated with 100 % accuracy and 100 % effectiveness for the whole range of rotating speeds of a separating roller when the needle pressure force was 10 N. The most effective separation of the PET/PVC mixture with accuracy and recovery efficiency above 96 % was achieved for a needle pressure force of 3.5 N but the process had to be conducted at an elevated temperature (65 °C).
