Abstract

PROCEDIMIENTO DE OBTENCION DE ESPUMAS LIQUIDAS PARA SU UTILIZACION COMO MATERIALES CELULARES SOLIDOS REFORZADOS. CONSISTE EN INCORPORAR MECANICAMENTE UN GAS O UNA MEZCLA DE GASES EN UNA RESINA DE POLIESTER INSATURADO. PARA REALIZAR LA INCORPORACION DEL GAS SE UTILIZA UNA TURBINA PROVISTA DE UN ROTOR CON SALIENTES PRISMATICOS Y CON VELOCIDAD PERIFERICA DE 200 A 500 METROS POR MINUTO. COMO MATERIAL DE REFUERZO SE EMPLEAN FIBRAS SINTETICAS QUE TIENEN UNA LONGITUD MAXIMA DE 5 MILIMETROS. EL PORCENTAJE EN PESO DEL MATERIAL DE REFUERZO CON RELACION A LA RESINA ESTA COMPRENDIDO ENTRE EL 10 Y EL 30 POR 100.
