新型热水锅炉阻垢缓蚀剂SG-218的研究与应用

Research and Application of A New Type Scale and Corrosion Inhibitor SG-218 for Hot-water Boiler

新型热水锅炉阻垢缓蚀剂SG-218,能够在金属表面形成致密的保护膜,可在锅炉给水自然p H条件下使用,在投加量100 mg/L时,对中高硬度水质阻垢率可达到90%以上、对碳钢的缓蚀率可达到90%以上。同时该药剂对铜、铝也有很好的缓蚀作用。

A new type scale and corrosion inhibitor SG-218 for hot-water boiler can form a compact protective film on the metal surface and can be used in boiler feed water under natural pH conditions. The scale inhibition rate can reach more than 90 % and the corrosion inhibition can reach above 90 % in high water hardness at dosage of 100 mg/L. At the same time, the agent on copper and aluminum has good corrosion inhibitionhas.
