Abstract

PROCESSO PARA A PRODUÇÃO DE UM GEL DE POLÍMERO SUPERABSORVENTE COM FINOS POLÍMEROS SUPERABSORVENTES RECICLADOS; PARA A PRODUÇÃO DE DE UM GEL DE POLÍMERO SUPERABSORVENTE A PARTIR DA RECICLAGEM DE POLIMEROS SUPERABSORVENTE; PARA A RECICLAGEM DE POLIMEROS SUPERABSORVENTE FINOS NA PRODUÇÃO DE GEL DE POLIMERO SUPERABSORVENTE COM UM POLIMERO SUPERABSORVENETE FINO RECICLADO PARA FORMAR POLIMEROS SUPERABSORVENTE FINOS TRATADOS CAUSTICAMENTE. É descrito um processo para a reciclagem de polímeros superabsorventes finos em um processo que inclui o tratamento dos polímeros superabsorventes finos com soda cáustica e uma etapa de polimerização para fazer o gel de polímero superabsorvente . O processo requer o tratamento dos polímeros superabsorventes finos com uma solução cáustica, seguido pela mistura com uma sol ução de monômero polimerizável, e polimerização da mistura do polímero superabsorvente fino e monômero para formar o polímero absorvente fluido aquoso. No processo, os polímeros finos são incorporados no gel de polímero novo e tornam-se indistinguíveis. O gel pode então ser triturado em um particulado seco e, em seguida, separado em uma parte com um tamanho de partícula mínima desejado em uma porção fina tendo menos do que o tamanho desejado. O particulado pode então ser revestido com um agente de ligação de superfície e aditivos de superfície e aquecido para a conversão da superfície.
