Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA PREPARACION DE MATERIALES ESPONJOSOS A PARTIR DE MATERIALES PLASTICOS REACTIVOS DE DOS COMPONENTES, UTILIZANDO DIOXIDO DE CARBONO COMO AGENTE DE EXPANSION Y MEDIANTE MEZCLA AL MENOS DE UNO DE LOS COMPONENTES REACTIVOS CON EL DIOXIDO DE CARBONO BAJO PRESION Y GENERACION DE UNA MEZCLA CONTENIENDO DIOXIDO DE CARBONO LIQUIDO, MEZCLADO CON EL OTRO COMPONENTE REACTIVO, EXPANSION Y ENDURECIMIENTO DEL MATERIAL PLASTICO. DE ACUERDO CON LA INVENCION LA SEGUNDA MEZCLA CONTENDIENDO DIOXIDO DE CARBONO SE EXPANDE MIENTRAS ES SEPARADA DE FORMA REPETIDA NUMEROSAS VECES EN UNA PLURALIDAD DE FLUJOS INDIVIDUALES BAJO EL EFECTO DE CAMBIO FRECUENTE DE VELOCIDAD DE CORTE, QUE TIENE VALORES MAXIMOS DE AL MEMOS 200/SEC, SIENDO DISTENDIDO.
