Abstract

PROCEDIMIENTO PARA ENDURECER RESINAS AMINOPLASTICAS. CONSISTE EN HACER REACCIONAR UNA RESINA AMINOPLASTICA, PREFERENTEMENTE EN FORMA DE UNA SOLUCION ACUOSA DE RESINA DE IMPREGNACION O DE AGLOMERACION, CON UNA SOLUCION ACUOSA NEUTRA, QUE PRESENTA UNA CONCENTRACION DEL 10 AL 60% DE SULFITO DE AMONIO JUNTO CON OTRAS SALES AMINICAS O AMONICAS DE ACIDOS MEDIANAMENTE FUERTES. DICHOS REACTIVOS ESTAN EN UNA PROPORCION DEL 0,1 AL 5% EN PESO DE SULFITO DE AMONIO CON RESPECTO AL CONTENIDO EN SUSTANCIA SOLIDA DE LA RESINA AMINOPLASTICA. LOS AMINOPLASTICOS ENDURECIDOS SE EMPLEAN COMO AGLOMERANTES DE PLACAS DE VIRUTA Y COMO AGLOMERANTES DE FIBRAS DE VIDRIO.
