| 摘要 |
Materials and a method are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing --Si (OR") (where R" is H, an alkyl group, Na, K, or NH) are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream or a high level nuclear waste processing plant. When materials of the present invention are added to the alkaline process stream, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces. The present materials are effective at treatment concentrations that make them economically practical. |
