1、性能 Performance
本品是一种新型分散阻垢剂,对于分散循环水中的悬浮物等杂质效果明显。它适宜于用水灰尘多的循环水中作为阻垢剂，如水泥厂自备电厂。本品对钙、镁有一定的络合作用。
SADP is a new type dispersing scale inhibitor, has good effect on dispersing the suspended substance in the circulating water. It is adept to circulating water with dusts as scale inhibitor, likeautonomous power plant （APP） of cement plant.It has certain complexation with calcium and magnesium ions.
2、用途 Usage
本品主要用于电厂、化工厂循环水中作为阻垢缓蚀剂。由于本品分散性能特别好，所以多用于灰尘多的循环水系统中作为阻垢剂。
SADP is widely used for scale and corrosion inhibitions in circulating water treatment in fields of power plant and chemical plant. Due to excellent dispersion performance, it is excessively used in circulating water system with dusts as scale inhibitor.
