Abstract

PROCEDIMIENTO PARA PRODUCIR UNA TUBERIA DE POLIURETANO QUE ESTA FIRMEMENTE FIJADA DENTRO DE UNA TUBERIA DE HORMIGON APLICANDOLE A LA CARA INTERIOR DE LA CITADA TUBERIA DE HORMIGON AL MENOS UNA PRIMERA CAPA DE POLIURETANO IMPERMEABLE QUE PUEDE TRASPASAR LOS POROS DEL HORMIGON. ESTE PROCEDIMIENTO CONSTA DE LAS FASES DE: (A) GIRAR LA CITADA TUBERIA DE HORMIGON EN TORNO A SU EJE LONGITUDINAL A TEMPERATURA AMBIENTE; (B) INTRODUCIR EN LA TUBERIA QUE GIRA UNA MEZCLA DE PRECURSORES DE POLIURETANO EN UNA CANTIDAD SUFICIENTE COMO PARA FORMAR UNA CAPA SOLIDA DE POLIURETANO CON AL MENOS 2 MM DE ESPESOR, TENIENDO LA CITADA MEZCLA UNA TEMPERATURA NO INFERIOR A 65 GRADOS CENTIGRADOS; (C) CONTINUAR EL CITADO GIRO, A TEMPERATURA AMBIENTE, A UNA VELOCIDAD Y DURANTE UN TIEMPO BASTANTES PARA SOLIDIFICAR LA MEZCLA. PRODUCTO COMPUESTO QUE CONSTA DE UNA TUBERIA EXTERNA DE HORMIGON Y UNA INTERNA DE MATERIAL POLIMERICO FORMADA AL MENOS A PARTIR DE UNA PRIMERA CAPA DE POLIURETANO EN CONTACTO CON LA SUPERFICIE INTERNA DE LA MENCIONADA TUBERIA DE HORMIGON.
