Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION DE VELLONES TERMOACTIVABLES, LIBRES DE MEDIOS DE SEPARACION Y DE SOPORTE SOBRE LA BASE DE POLIURETANOS HIDROXI POLIESTER CON VISCOSIDADES DESDE 600 HASTA 3.500 MPA.S, MEDIDAS COMO VISCOSIDAD DE SOLUCION EN METILETILENCETONA (15 % BROOKFIELD LVT-VISKOSIMETER, SPINDEL 3, 60 UPM, 23 PERFICIAL EN LA ZONA DESDE 5 HASTA 200 G/M2, QUE ESTA CARACTERIZADO PORQUE EL VELLON SE FORMA POR MEDIO DE UN PROCESO DE SOPLADO DE COLADA EN TEMPERATURAS DE MASA DESDE 230 HASTA 260 SE UTILIZA UNA BANDA DE DEPOSITO, CUYO MATERIAL MUESTRA UNA TENSION SUPERFICIAL DESDE 18,5 X 10 A LA MENOS 5 N/CM HASTA 46 X 10 A LA MENOS 5 N/CM. LOS VELLONES ELABORADOS CON EL PROCESO DE ACUERDO CON LA INVENCION SE DESARROLLAN LIBRE DE BLOQUEO SIN LA ADICION DE MEDIOS DE SEPARACION O DE DISTANCIA Y SON APROPIADOS PREFERENTEMENTE PARA EL PEGADO DE SUBSTRATOS DIFERENTES.
