7、4Pit吕离子交换树脂是火力发电厂水处理用的一种重要材料，用量大、品种多、价值高，其性能优劣直接影响水处理系统工作的安全性和经济性。本标准是对DL/T519-1993《火力发电厂水处理用离子交换树脂验收标准》的修订。与DL1T519-1993版标准相比，本标准发生了如下主要变化:—删去了原标准的附录E和附录Fo—对原标准的附录C、附录D和附录G给出了测定方法允许差。—改用渗磨圆球率表示凝胶型树脂的强度，同时给出了指标。—改用范围粒度、上限粒度和下限粒度表示树脂的粒度，同时给出了指标—对混床树脂的有效粒径进行了规定。—增加了凝结水处理用离子交换树脂的技术指

8、标。—增加了丙烯酸系阴离子交换树脂的技术指标。本标准的附录A是资料性附录。附录B
