Realizzazione di due metodi di laboratorio per valutare la pulizia della scaglia di polipropilene post consumo lavato dall' impianto di Sirmax S.p.A. I metodi sono accomunati da una prima fase di lavaggio simulato e differiscono nella seconda fase, in quanto in un test vengono misurati i solidi disciolti nell'acqua di lavaggio mentre nel secondo è misurata la domanda chimica di ossigeno(COD).

Abstract
Implementation of two laboratory tests to evaluate the cleanliness of post-consumer polypropylene flakes washed by the Sirmax S.p.A. plant. Both tests share an initial simulated washing phase but differ in the analysis, as in one case the dissolved solids in the washing water are measured, while in the other the chemical oxygen demand values are assessed."File | Dimensione | Formato | |
