Abstract

composições e métodos para melhorar a capacidade de fluir de polímeros superabsorventes. um método inclui misturar um material hidrofóbico seco com um polímero superabsorvente seco para melhorar a capacidade de fluir do polímero em condições úmidas dentro de uma passagem de máquina com um tempo de residência. a aplicação de polímeros superabsorventes na agricultura é desejável para auxiliar o crescimento das plantas em condições cada vez mais quentes e secas. no entanto, as aplicações de plantio a granel seco normalmente usadas na agricultura exigem que a emenda seca passe por canais confinados e poros estreitos. isso é problemático porque os polímeros absorvem rapidamente a umidade do ambiente e aderem ao equipamento de plantio, causando incrustações e entupimentos. a melhoria na capacidade de fluir fornecida pelas composições divulgadas neste documento é na medida em que o polímero superabsorvente tipo amido pode ser aplicado usando aplicações de plantio a granel seco nas condições úmidas da flórida na primavera. surpreendentemente, as misturas secas melhoram a capacidade de fluir sem prejudicar a capacidade dos polímeros de absorver rapidamente a umidade da chuva.
