Abstract

"PROCESSO PARA PREPARAçãO DE PARTìCULAS DE RPET COM DIMENSõES EXTREMAMENTE REDUZIDAS". Trata-se de um processo para preparação de partículas de RPET de dimensões extremamente reduzidas, compreendendo a provisão de uma quantidade de flocos de RPET, aumento da cristalinidade dos flocos de RPET, separação de uma parte dos flocos de RPET com uma menor densidade de partícula dos restantes flocos de RPET, e trituração dos restantes flocos de RPET, para preparação de partículas de RPET com um tamanho médio de partícula inferior a cerca de 500 mícrons.
