Abstract

HABITUALMENTE, LA ESPUMA DE LATEX SE FABRICA EN MOLDES METALICOS QUE SE CALIENTAN CON VAPOR. EN MOLDES PROFUNDOS, EL TIEMPO DE GELATINIZACION Y VULCANIZACION ES LARGO; EL PROCEDIMIENTO REQUIERE MUCHOS APARATOS Y CONLLEVA ALTOS GASTOS DE ENERGIA. EL INVENTO PROPONE QUE LA ESPUMA DE LATEX SE VIERTA EN UN MOLDE DE UN MATERIAL NO METALICO CUYA TEMPERATURA EN LAS SUPERFICIES DE CONTACTO ENTRE LA ESPUMA Y EL MOLDE PUEDE OSCILAR ENTRE 45 C Y 100 C, Y SE CALIENTA DE 3 A 10 MINUTOS, MEDIANTE MICROONDAS, COMO MAXIMO, HASTA UNA TEMPERATURA DE 100 C, POR LO CUAL LLEGA A VULCANIZARSE. AUN CUERPOS DE ESPUMA GRUESOS ADOPTAN ASI UNA ESTRUCTURA POROSA HOMOGENEA Y UNAS CALIDADES DE ROTURA Y FLEXION REGULARES. MEDIANTE ESTE PROCEDIMIENTO, SE FACILITA UNA PRODUCCION DE ESPUMA LATEX DE CONSTANTE CALIDAD Y POCO COSTOSA, TAMBIEN EN GROSORES ELEVADOS DE CAPA.
