Abstract

"PROCESSO E PROCESSO DE FIAçãO". Um material fluidificado é emitido a partir de um bocal que compreende jato de ventilador na saída, fazendo com que a mistura seja difundida à medida que é emitida. O material emitido é recolhido sobre uma superfície coletora móvel localizada em distância de 0,25 a 13 cm da saída do bocal, antes do início de turbulência em larga escala no jato de fluido. O produto resultante possui boa uniformidade de peso base.
