表面活性剂由于具有不对称“两亲分子”的独特结构，可在界面形成定向排列，并在溶液中形成胶团，因而可以改变溶液的许多性质，起到改进生产工艺、增加产品品种、提高产品质量、节能、降低成本、提高劳动生产率的关键作用，在电力行业中也获得了广泛应用。为此以例说明，详细分析表面活性剂在火电厂热力设备清洗、给水处理、废水处理、循环冷却水处理及热力设备防腐蚀等方面的作用机理及应用。 Due to the unique structure of asymmetric “amphiphilic molecules,” surfactants can be aligned at the interface and form micelles in solution, thus changing many of the properties of the solution, improving the manufacturing process, increasing product variety and increasing The key role of product quality, energy saving, cost reduction and labor productivity is also widely used in the power industry. To illustrate this case, a detailed analysis of surfactant in thermal power plant thermal equipment cleaning, water treatment, wastewater treatment, circulating cooling water treatment and thermal equipment, anti-corrosion mechanism and application.
