制备方法与用途

用途 

用作电镀添加剂中间体，用于配制镀铜光亮剂，使其具有良好的延展性及光亮性

用途 

镀铜光亮剂，与聚醚和润湿剂等表面活性剂配合使用，也可与其他含硫光亮剂结合使用，可获得光亮延展性好的镀层。同时也可用于贵金属的化学镀，也可作为电镀稳定剂。DPS属于中电流密度区光亮剂，该产品最早由德国RASCHIG公司引入国内，主要作用是出光快，镀液的稳定性好。大致的使用方法：与SPS配合使用，对于优质的SPS而言，SPS与DPS按照1：1配合使用，而对于市购普通的SPS，由于其中含有DPS成分，则要调整其比例。添加DPS后，可以减少电镀故障，它可以调节SPS、M、N的平衡，并能络合一价的铜离子。
