Abstract

PROCEDIMIENTO PARA LA OBTENCION DE MICROCAPSULAS. SE DISPERSA EN AGUA EL MATERIAL DEL NUCLEO DE LA MICROCAPSULA EN PRESENCIA DE POLIMEROS, HOMO O COPOLIMERIZADOS QUE CONTENGAN GRUPOS IONICOS CON CARGA NEGATIVA, CON UN PH DE 3-6,5, A TEMPERATURA DE 20-100 GC. PARA OBTENER EL MATERIAL DE PARED DE LA MICROCAPSULA SE AGREGA, REMOVIENDO, UNA SOLUCION ACUOSA DE PRECONDENSADOS DE MELAMINA/FORMALDEHIDO Y/O EL ETER METILICO DEL FORMALDEHIDO. UNA VEZ CUBIERTAS LAS GOTAS DISPERSADAS POR EL MATERIAL DE PARED SE ENDURECEN LAS CAPSULAS AGITANDO CON METODOS CONVENCIONALES. DE APLICACION EN SISTEMAS DE REGISTRO SENSIBLES A LA PRESION.
