摘要
循环水系统换热设备出现换热效率降低、设备腐蚀、结垢现象是普遍存在的;结垢物质一般有碳酸钙垢、锌垢、磷酸钙垢、硅酸盐垢、硫酸钙垢,而硫酸钙垢是比较难处理的。当补水中硫酸根离子浓度过高时就会产生硫酸钙垢,而且可能会引起垢下腐蚀;因此研发出高效的阻硫酸钙垢缓蚀阻垢剂应用在硫酸根离子含量高的冷却水系统中具有重要的意义。
The main causes of heat exchange efficiency reduction and leakage of heat exchange equipment in circulating water system are scaling and corrosion.The scaling substances generally include calcium carbonate scale,zinc scale,calcium phosphate scale,silicate scale and calcium sulfate scale.When the concentration of sulfuric acid ions in the rehydration water is too high,calcium sulfate scale will be produced,and it may cause scale corrosion.Therefore,it is ofgreat importance to develop effective calcium sulphate scale inhibitor for cooling water system with high content of sulfate ions.
