Abstract

Un sustrato para uso en una suspension acuosa tiene un revestimiento polimerico para proporcionar una superficie adherente y pegajosa. El recubrimiento de polimero tiene una sustancia quimica para hacer que la superficie sea hidrofobica para atraer particulas minerales hidrofobicas o hidrofobizadas en la suspension. El sustrato puede tomar la forma de una cinta transportadora, una microesfera, una malla, un impulsor, un filtro o una superficie plana. El sustrato tambien puede ser una espuma de celda abierta. El recubrimiento polimerico puede modificarse con agentes de pegajosidad; plastificantes; agentes de reticulacion; agentes de transferencia de cadena; extensores de cadena; promotores de adherencia; copolimeros arilo o alquilicos; copolimeros fluorados y/o aditivos; agentes hidrofobizantes tales como hexametildisilazano; particulas inorganicas tales como silice, silice hidrofobica y/o silice hidrofobica ahumada; resina MQ ; y/u otros aditivos para controlar y modificar las propiedades del polimero.A substrate for use in an aqueous suspension has a polymeric coating to provide an adherent and tacky surface. The polymer coating has a chemical to make the surface hydrophobic to attract hydrophobic or hydrophobic mineral particles into the suspension. The substrate can take the form of a conveyor belt, a microsphere, a screen, an impeller, a filter, or a flat surface. The substrate can also be an open cell foam. The polymeric coating can be modified with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adherence promoters; aryl or alkyl copolymers; fluorinated copolymers and / or additives; hydrophobicizing agents such as hexamethyldisilazane; inorganic particles such as silica, hydrophobic silica and / or fumed hydrophobic silica; MQ resin; and / or other additives to control and modify the properties of the polymer.
