Abstract

resumo processo para a produção de pós de dispersão a invenção oferece um processo para produção de pós de dispersão através da secagem por pulverização de dispersões poliméricas aquosas e adição de agentes antibloqueantes em um secador de atomização rotativa, caracterizado pelo fato do agente antibloqueante ser transmitido através de ar comprimido, total ou parcialmente, por uma fenda circular que é formada por uma moldagem disposta concentricamente em torno da estrutura do atomizador rotativo, e que termina a uma distância acima da extremidade superior da placa do atomizador rotativo.
