Abstract

EL PRESENTE INVENTO SUMINISTRA UN PROCESO PARA LA PRODUCCION DE ARTICULOS MOLDEADOS MEDIANTE EXPANSION DE UNA RESINA DE POLIETILENO LINEAL DE BAJA DENSIDAD EN UN MOLDE QUE COMPRENDE LA COMPRESION DE LAS GOTAS DE RESINA DE POLIETILENO LINEAL DE BAJA DENSIDAD PREEXPANDIDO QUE TIENEN DOS PUNTOS DE FUSION (MEDIDOS MEDIANTE UN CALORIMETRO DE EXPLORACION DIFERENCIAL) Y QUE TIENEN UNA PROPORCION: 5% MENOR IGUAL A AH / AL X 100% MENOR IGUAL 80% USANDO UN GAS A PRESION, EL LLENADO DE UN MOLDE CAPAZ DE CERRARSE PERO INCAPAZ DE SER SELLADO CON DICHAS GOTAS COMPRIMIDAS, EL PURGADO DE DICHO MOLDE Y EL CALENTAMIENTO Y FUSION DE LAS GOTAS CON VAPOR, EN DONDE LA PROPORCION DE LA COMPRESION DE LAS GOTAS PREEXPANDIDAS INMEDIATAMENTE ANTES DE DICHO CALENTAMIENTO CON VAPOR CON RESPECTO A LAS GOTAS PREEXPANDIDAS ORIGINALES SE MANTIENE ENTRE EL 5 AL 60% (AL ES EL PUNTO MAXIMO EN EL PUNTO DE FUSION EN LA PARTE DE BAJA TEMPERATURA (TML) Y AH ES EL PUNTO MAXIMO EN EL PUNTO DE FUSION EN LA PARTE DE ALTA TEMPERATURA (TMH)). DE ACUERDO CON EL PRESENTE INVENTO, PUEDEN PRODUCIRSE ARTICULOS MOLDEADOS DE POLIETILENO LINEAL DE BAJA DENSIDAD QUE TIENEN UN RANGO DE CONTRACCION DIMENSIONAL MINIMIZADO (SEGURIDAD DIMENSIONAL BUENA) Y UNA PROPORCION DE FUSION EXCELENTE Y BUENA APARIENCIA DE SU SUPERFICIE.
