Abstract

"PROCESSO E APARELHO PARA PROCESSAR PARTìCULAS DE POLìMERO EXPANSìVEIS, ARTIGO DE ESPUMA FORMADO DE PARTìCULAS DE POLìMERO E PARTìCULAS". Processo para o processamento de partículas de polímero expansíveis por exemplo, poliestireno (EPS) que elimina a etapa de maturação entre as etapas de pré-expansão e de moldagem. As partículas expansíveis são primeiro superpressurizadas com gás, por exemplo, ar, dióxido de carbono, nitrogênio e misturas dos mesmos, a uma pressão de entre 500 e 8000 kPa e a uma temperatura de entre -20<198>C e 130<198>C durante 15 a 7200 minutos para criar uma pressão de gás nas partículas. Utilização da pressão de gás nas partículas, pré-expansão das partículas com um meio de aquecimento, por exemplo, vapor d'água a uma temperatura de entre 100<198>C e 120<198>C e uma pressao na faixa de acima da pressão atmosférica e abaixo da pressão de gás nas ditas partículas, isto é, 50 até 200 kPa durante 5 até 120 segundos. As partículas pré-expandidas são secas ao ar no pré-expansor enquanto se mantém uma pressão positiva nas partículas; são opcionalmente transferidas para um silo com pressão e então são transferidas para uma máquina de moldagem em que a pressão de gás nas partículas é usada para formar um artigo de espuma.
