Abstract

PROCEDIMIENTO PARA LA REGENERACION DE POLIETILENO PARCIALMENTE DEGRADADO. PROCEDIMIENTO PARA LA REGENERACION DE POLIETILENO PARCIALMENTE DEGRADADO, ESPECIALMENTE DE POLIETILENO DE BAJA DENSIDAD UTILIZADO COMO CUBIERTA DE INVERNADERO Y PARCIALMENTE DEGRADADO POR ACCION DE LA LUZ SOLAR. EL PROCEDIMEINTO CONSISTE EN SOMETER AL POLIMERO PARCIALMENTE DEGRADADO Y SOMETIDO A UN TRATAMIENTO FISICO PREVIO CONDUCENTE A DISMINUIR SU TAMAÑO Y RETIRAR IMPUREZAS, A TRATAMIENTO CON UNA MEZCLA CONSTITUIDA POR UN AGENTE ESTABILIZANTE Y UN ANTIOXIDANTE JUNTO CON CANTIDADES VARIABLES DE MATERIA PRIMA VIRGEN EN UNA EXTRUSORA A TEMPERATURAS INFERIORES A 170GC. COMO AGENTE ANTIOXIDANTE PUEDE UTILIZARSE UN DERIVADO FENOLICO Y COMO ESTABILIZANTE UN FOSFITO. LAS GRANZAS ASI OBTENIDAS CUMPLEN LAS ESPECIFICACIONES TECNICAS NECESARIAS PARA SU POSTERIOR TRANSFORMACION Y UTILIZACION EN DIFERENTES APLICACIONES. ESTE PROCEDIMIENTO PERMITE EL RECICLADO Y REUTILIZACION DE PLASTICO AGRICOLA EVITANDO LA CONTAMINACION MEDIAMBIENTAL QUE SUPONE EL TRATAMIENTO INADECUADO DEL MISMO.PROCEDURE FOR THE REGENERATION OF PARTIALLY DEGRADED POLYETHYLENE. PROCEDURE FOR THE REGENERATION OF PARTIALLY DEGRADED POLYETHYLENE, ESPECIALLY OF LOW DENSITY POLYETHYLENE USED AS A GREENHOUSE COVER AND PARTIALLY DEGRADED BY ACTION OF SUNLIGHT. THE PROCEDURE CONSISTS OF SUBMITTING THE PARTIALLY DEGRADED POLYMER AND SUBJECTING TO A PREVIOUS PHYSICAL TREATMENT LEADING TO REDUCE ITS SIZE AND REMOVE IMPURITIES, TO TREATMENT WITH A MIXED PREVIOUS A VIRGIN DEPUTY OF A VARIOUS MISTERY, A PREVIOUS MISTERY, AND A FORTENING MATERNITY, AND A FORMER VINTAGE, A PREVIOUS DEBATE, AND ANTIOXITIRE, A VIRGIN DEMAND, A PREVIOUS MISTERY, AND ANTIOXITIRE, A PRESTIGENT, AND A PRESTIGIOUS DEPENDENT, TEMPERATURES LESS THAN 170GC. AS A ANTIOXIDANT AGENT A PHENOLIC DERIVATIVE CAN BE USED AND AS A PHOSPHITE AS A STABILIZER. THE GRAINS SO OBTAINED COMPLY WITH THE NECESSARY TECHNICAL SPECIFICATIONS FOR THEIR LATER TRANSFORMATION AND USE IN DIFFERENT APPLICATIONS. THIS PROCEDURE ALLOWS THE RECYCLING AND REUSE OF AGRICULTURAL PLASTIC, AVOIDING THE ENVIRONMENTAL POLLUTION THAT SUBSTITUTES THE IMPROPER TREATMENT OF THE SAME.
