| 发明名称 | Methods of using sand composites to control dust | ||
| 摘要 | A composite is characterized by particulates of sand wherein at least a portion of the surface of the particulates is coated with a polycationic polymer. The presence of the polycationic polymer on the surface of the particulates reduces the amount of dust generated during handling and use of the sand. The polycationic polymer further reduces the amount of dust generated during transport of the sand as well during manufacture, treatment or processing of the sand. | ||

| 主权项 | 1. A method of reducing the amount of dust generated from particulates of sand consisting of forming a composite consisting of the sand particulates and a coating coated onto at least a portion of the surface of the sand particulates, the coating consisting essentially of (i) a polycationic polymer; or (ii) a polycationic polymer and surface-charged nanoparticles capable of binding to the polycationic polymer. | ||
