Abstract

PROCEDIMIENTO PARA LA REUTILIZACION DE DUROPLASTOS QUE CONTIENEN FIBRAS SE PROPONE UN PROCEDIMIENTO PARA LA REUTILIZACION DE MATERIAS RESIDUALES DE ESTRUCTURAS FIBROSAS IMPREGNADAS CON DUROPLASTOS NO ENDURECIDOS. LAS MATERIAS RESIDUALES TRITURADAS SE EXTRAEN EN UN DISOLVENTE DE BAJO PUNTO DE EBULLICION BAJO LA ACCION DE ALTAS FUERZAS DE CIZALLADURA. LOS MATERIALES FIBROSOS DISPERSOS SE TRANSFORMAN EN PRODUCTOS A MANERA DE VELOS, Y LA SOLUCION DE DUROPLASTO SE UTILIZA, DESPUES DE SU CONCENTRACION, COMO AGENTE IMPREGNANTE PARA ESTRUCTURAS FIBROSAS.
