Abstract

Se refiere a un sustrato para uso en una pasta acuosa, tiene un recubrimiendo polimerico para proporcionar una superficie conforme y pegajosa. El recubrimiendo polimerico tiene un producto quimico que hace que la superficie sea hidrofobica para atraer particulas minerales hidrofobizadas o hidrofobicas en la pasta. La superficie tiene una estructura de rugosidad de la superficie en el rango de nanoescala a microescala. El sustrato puede adoptar la forma de una cinta transportadora, un talon, una malla, un impulsor, un filtro o una superficie plana. El sustrato tambien puede ser una espuma de celula abierta. El recubrimiendo polimerico puede ser modificado con adhesivos; plastificantes; agentes reticulantes; agentes de transferencia de cadena; extensores de cadena; promotores de adhesion; copolimeros arilicos o alquitranados; copolimeros fluorados y/o aditivos; agentes hidrofobicantes como hexametildisilazano; particulas inorganicas corno silice, silice hidrofobica y/o silice hidrofobica ahumada; resinas de MQ; y/u otros aditivos para el control y modificacion de las propiedades del polimero.
