Abstract

PROCEDIMIENTO PARA LA FABRICACION CONTINUA DE PERFILES DE ESPUMA SINTETICA TERMOPLASTICA. UN FLUJO DE MATERIAL SINTETICO TERMOPLASTICO FUNDIDO, CONTENIENDO UN AGENTE DE EXPANSION, SE INYECTA CONTINUAMENTE EN EL EXTREMO DE UN CANAL TUBULAR DE SECCION CERRADA, CUYAS PAREDES SE ENFRIAN DESDE EL EXTERIOR. EL MATERIAL SE HACE AVANZAR A TRAVES DEL CANAL A UNA VELOCIDAD TAL QUE LA ESPUMA SE EXPANDE Y LLENA COMPLETAMENTE LA SECCION TRANSVERSAL DEL MISMO, SIENDO LA LONGITUD DEL CANAL TAL QUE LA ESPUMA SALE CONSOLIDADA DIMENSIONALMENTE.
