    Abstract: Materials and a process are provided whereby polymers with the pendant group or end group containing - -Si(OR") 3 (where R" is H, an alkyl group, Na, K, or NH 4 ) are used to control aluminosilicate scaling in a Bayer process. When materials of the present invention are added to the Bayer liquor before the heat exchangers, they reduce and even completely prevent formation of aluminosilicate scale on heat exchanger walls. The present materials are effective at treatment concentrations that make them economically practical.

    Abstract: Materials and a method are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing - Si (OR") 3 (where R" 'is H, an alkyl group, Na, K, or NH 4 ) are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream. 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.

    Abstract translation: 提供材料和方法，其中具有至少0.5摩尔％的侧基或末端基团含有-Si（OR“）3（其中R”'为H，烷基，Na，K 或NH 4）用于控制具有碱性工艺流（例如制浆机工艺流）的工业过程中的硅铝酸盐垢。 当将本发明的材料添加到碱性工艺流中时，它们减少甚至完全防止在诸如蒸发器壁和加热表面的设备表面上形成铝硅酸盐垢。 本材料在治疗浓度上有效，使其具有经济实用性。

    Abstract: Materials and a process are provided whereby polymers with the pendant group or end group containing - -Si(OR')3 (where R' is H, an alkyl group, Na, K, or NH4) are used to control aluminosilicate scaling in a Bayer process. When materials of the present invention are added to the Bayer liquor before the heat exchangers, they reduce and even completely prevent formation of aluminosilicate scale on heat exchanger walls.
