Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UN CUERPO ESPUMADO CELULAR DE UNA RESINA BASADA EN CLORURO DE VINILO. SE MEZCLA LA RESINA BASADA EN CLORURO DE VINILO CON UN AGENTE NUCLEANTE Y UNA RESINA ACONDICIONADORA DE ESPUMA. SE INTRODUCE LA COMPOSICION EN UNA MAQUINA EXTRUSORA Y SE CALIENTA A PRESION ATMOSFERICA. SE IMPREGNA LA COMPOSICION CON UN AGENTE ESPUMADOR VOLATIZABLE, QUEDANDO COMPLETAMENTE GELIZADA. SE LLEVA LA MEZCLA A UNA ZONA DE PRESION REDUCIDA, CON REFRIGERACION SIMULTANEA, OBTENIENDOSE UN CUERPO CELULAR MEDIANTE LA EXPANSION DE LA MEZCLA EN ESTAS CONDICIONES.
