Abstract

La presente solicitud revela un método de encolado para producir papel. Un anhídrido alquenilsuccínico (ASA) se añade a un proceso de fabricación de papel. Una sal de aluminio se añade en una o varias etapas del proceso durante el proceso de fabricación de papel. Con preferencia, la sal de aluminio es una sal de aluminio que puede generar ion de aluminio libre en solución acuosa. El método de encolado de la presente solicitud mejora la eficacia de uso de un agente de encolado y la sal de aluminio, y proporciona papel con un alto contenido de humedad.
