Abstract

Un procedimiento incluye mezclar un material hidrófobo seco con un polímero superabsorbente seco para mejorar la fluidez del polímero en condiciones húmedas dentro de un pasaje de máquina que tiene un tiempo de residencia. La aplicación de polímeros superabsorbentes en agricultura es deseable para ayudar al crecimiento de las plantas en condiciones cada vez más cálidas y secas. Sin embargo, las aplicaciones en plantaciones en granel seco que se utilizan normalmente en la agricultura requieren que la enmienda seca pase a través de canales confinados y poros estrechos. Esto es problemático porque los polímeros absorben rápidamente la humedad del ambiente y se adhieren al equipo de plantación causando incrustaciones y obstrucciones. La mejora en la fluidez proporcionada por las composiciones desveladas en el presente memoria es en la medida en que el polímero similar al almidón superabsorbente se puede aplicar usando aplicaciones de siembra en granel secos en las condiciones húmedas de Florida en la primavera. Inesperadamente, las mezclas secas mejoran la fluidez sin socavar la capacidad de los polímeros para absorber rápidamente la humedad de la lluvia.
