Abstract

UN METODO PARA PREPARAR PRECURSORES ACRILICOS CON CARACTERISTICAS MEJORADAS APROPIADOS PARA LA TRANSFORMACION EN FIBRAS DE CARBONO DE CARACTERISTICAS MECANICAS SUPERIORES COMPRENDE EL ENROLLADO HUMEDO DE UN POLIMERO ACRILICO DISUELTO EN DIMETILACETAMIDA SEGUIDO POR LA COAGULACION EN UN BAÑO DE MEZCLA BINARIA DISOLVENTE-NO DISOLVENTE DE COMPOSICION Y TEMPERATURA RIGUROSAMENTE CONTROLADAS, Y UNA SERIE DE OPERACIONES DE ESTIRAMIENTO DE ESTADO CONTROLADO CON FASES DE LAVADO INTERCALADAS, SEGUIDO POR EL SECADO DE LOS HILOS SU RECOGIDA FINAL. EL METODO SE CARACTERIZA ESENCIALMENTE POR SU FASE DE COAGULACION, QUE SE LLEVA A CABO EN CONDICIONES DE TEMPERATURA Y COMPOSICION DEL BAÑO RIGUROSAMENTE CONTROLADAS, PARA OBTENER AL FINAL DEL PROCESO UN HILO ACRILICO QUE TIENE UNA ESTRUCTURA PERFECTAMENTE COMPACTA LIBRE DE IMPERFECCIONES (HUECOS), UNA SECCION PERFECTAMENTE CIRCULAR Y UNAS CARACTERISTICAS MECANICAS QUE SON CLARAMENTE MEJORES QUE LAS DE HILOS ACRILICOS DE IDENTICA COMPOSICION OBTENIDOS MEDIANTE PROCESOS DE ROTACION DEL TIPO CONOCIDO. EL DESTINO ESPECIFICO DEL HILO ACRILICO ES LA PRODUCCION DE FIBRAS DE CARBONO DE ALTO RENDIMIENTO.A METHOD FOR PREPARING ACRYLIC PRECURSORS WITH IMPROVED CHARACTERISTICS SUITABLE FOR THE TRANSFORMATION INTO CARBON FIBERS OF SUPERIOR MECHANICAL CHARACTERISTICS COMPRISES THE WINDING OF A DISSOLVED POLYMER LAUNDRY DISPOSED BY DIGETILACENTE BAUTIO, AVAILABLE STRICTLY CONTROLLED, AND A SERIES OF CONTROLLED STATE STRETCHING OPERATIONS WITH INTERWASHED WASHING PHASES, FOLLOWED BY THE DRYING OF THE THREADS THEIR FINAL COLLECTION. THE METHOD IS ESSENTIALLY CHARACTERIZED BY ITS COAGULATION PHASE, WHICH IS CARRIED OUT IN RIGOROUSLY CONTROLLED TEMPERATURE AND BATH COMPOSITION CONDITIONS, TO OBTAIN AT THE END OF THE PROCESS AN ACRYLIC THREAD, WHICH HAS A PERFECTLY COMPACT STRUCTURE. PERFECTLY CIRCULAR SECTION AND SOME MECHANICAL CHARACTERISTICS THAT ARE CLEARLY BETTER THAN THOSE OF ACRYLIC THREADS OF IDENTIFIC COMPOSITION OBTAINED THROUGH ROTATION PROCESSES OF THE KNOWN TYPE. THE SPECIFIC DESTINATION OF ACRYLIC THREAD IS THE PRODUCTION OF HIGH PERFORMANCE CARBON FIBERS.
