Abstract

"MéTODO PARA A FABRICAçãO CONTìNUA DE GRANULADO PLáSTICO EXPANSìVEL". A presente invenção refere-se a um método, com o uso do qual granulado plástico expansível (G) pode ser fabricado continuamente, com um material derretido de plástico (F) sendo impregnado usando um agente de expansão de fluido (B) e o material derretido impregnado sendo granulado. O método é executado por meio de uma instalação, que inclui os seguintes componentes: - pelo menos um aparelho de alimentação de produção de pressão (10) para o material derretido, que é em particular um aparelho de alimentação de bombeamento volumétrico, - um aparelho de medição (9) para o agente de expansão, - aparelho de contato e homogeneização (2) para a impregnação do material derretido, - pelo menos um esfriador (3) para o material derretido impregnado, - um granulador submerso (6) e - um controle de instalação (1). A granulação é executada usando um líquido que é usado no granulador como um meio de resfriamento e transporte para o granulado. O líquido é em particular água ou uma salmoura. Uma pressão elevada é exercida pelo líquido usado durante a granulação, visto que uma ação de expansão do agente de expansão no granulado ainda não solidificado é pelo menos parcialmente suprimida. A regulação dos parâmetros a serem ajustados para a granulação, a saber, a temperatura e a pressão do material derretido impregnado é efetuada na entrada do granulador. Nessa regulação, as medições dos parâmetros citados são feitas e também os valores de medição são comparados com valores desejados e os desvios dos valores desejados devido ao controle da unidade são usados para influenciar a absorção de calor do material derretido impregnado pelo esfriador ou esfriadores.
