Description

technical field [0001] The invention relates to the technical field of scale inhibitors, in particular to a preparation method of a complex high-efficiency scale inhibitor. Background technique [0002] In enterprises such as chemical or petrochemical industries, industrial water consumption is huge. If direct-flow water is used in the cooling process in this type of industry, it will cause a serious waste of water resources, so circulating water is often used for cooling. However, due to high-temperature evaporation and repeated use of circulating cooling water, the dissolved salt in the water will be concentrated, which will lead to problems such as corrosion and scaling on the surface of the equipment. On the one hand, this will increase the power consumption of the equipment and reduce the cooling efficiency; on the other hand, the increase of unstable factors in the production process may lead to serious safety hazards. At present, scale inhibitors are mostly used in ...
