摘要

针对以氯气为主要杀菌剂的系统

存在正磷升高、局部介质温度较高的换热器形成磷酸钙垢等问题进行了研究

在循环水处理配方中引入了耐氯分解能力强、分散能力好的缓蚀阻垢成分

筛选出代号为Fu-93a（P）的缓蚀阻垢剂

经生产应用腐蚀速率达到0.0222mm/a

粘附速率达到2.64mcm

水中正磷长期维持在1.0mg/L以下。

Abstract

The increase of ortho-phosphates and the formation of calcium phosphate scale in heat exchangers with partial high-temperature fluids in systems using chlorine as the main sterilizer are studied in this paper.A corrosion and scale inhibitor with the code 0f Fu-93 a（P）has been screened out by introducing corrosion and scale inhibiting ingredients with good dispersion and strong resistance against chlorine decomposition into the formula. The application of this inhibitor in production shows that the corrosion rate reaches 0.0222mm/a and the adhesion rate reaches 2.64 mcm

meanwhile the ortho-phosphates in the water always keep below 1.0 mg/L.
