目前,在大型石油化工企业、大型合成氨厂、大型轧钢厂、油井、气井等工业领域中,水质处理已成为极重要的课题。以冷却水为例,由于冷却过程的蒸发,水中溶解的无机盐被浓缩,随之而来的是产生结垢。结垢后设备传热系数下降,结果导致产量下降,因此对冷却水的缓蚀防垢研究引起了极大的注意。六十年代以前,防结垢剂主要使用无机化合物,如聚 At present, water treatment has become an extremely important issue in large-scale petrochemical enterprises, large-scale ammonia plants, large rolling mills, oil wells, gas wells and other industrial fields. Taking cooling water as an example, due to the evaporation of the cooling process, inorganic salts dissolved in the water are concentrated, followed by fouling. After fouling equipment heat transfer coefficient decreased, the result led to decline in production, so the cooling water corrosion prevention and control caused great attention. Before the sixties, antifouling agents mainly used inorganic compounds, such as poly
