三种多元共聚物的阻垢与缓蚀性能

PERFORMANCES OF SCALE INHIBITION AND ANTI-CORROSION OF THREE SYNTHETIC COPOLYMERS

对合成的３种多元共聚物的阻垢与缓蚀性能进行了评定，初步探讨了其性能与分子中所含特性基团之间的关系。结果表明，对于所合成的３种共聚物，其对碳酸钙的阻垢性能主要取决于分子中的羧基密度；苯环基因能够提高共聚物对氧化铁的分散能力；而酰胺基和羟基则增强它们对碳钢的缓蚀性能。

Relationships between performances and structures of three synthetic coPOlymers were studied. Experimental results indicate that scale inhibition properties of the copolymers on calcium carbonate mainly depend on the density of carboxylic group; their dispersing powers on ferric oxide are raised by benzene ring group; and their anti-corrosion performances on mild steel are enhanced by amidogen and hydroxy groups.
