Abstract

PROCEDIMIENTO PARA MODIFICAR EL CONTENIDO DE AGUA DE UN MATERIAL QUE ABSORBE AGUA O QUE DESPRENDE AGUA. SE UTILIZA UNA LAMINA QUE SEPARA A ESTE MATERIAL POR LO MENOS PARCIALMENTE RESPECTO DEL ESPACIO CIRCUNDANTE Y ES IMPERMEABLE PARA AGUA LIQUIDA, PERO PERMEABLE PARA AGUA GASEOSA. COMO LAMINA SE UTILIZA UNA DE POLI(ALCOHOL VINILICO), INSOLUBLE EN AGUA A UNA TEMPERATURA POR DEBAJO DE 80<025>C, QUE TIENE UN INDICE DE ESTER DE 0 A 200 MG DE KOH/G Y CUYA SOLUCION ACUOSA AL 4% EN PESO PRESENTA A UNA TEMPERATURA DE 20<025>C UNA VISCOSIDAD DE 4 A 100 MPA.S, SIENDO TRATADA EVENTUALMENTE LA LAMINA POSTERIORMENTE DE MODO MECANICO O QUIMICO.
