ＰＡＧ淬火剂是以特定的聚醚类非离子型高分子聚合物（ＰＡＧ）加上能获得其他辅助性能的复合添加剂和适量的水而制成的。使用中，淬火液可能发生的变化主要有两类：一类是其冷却性能上的变化，另一类是其防锈和防腐败等性能的变化。因为使用ＰＡＧ淬火剂的目的是调节水的... PAG quenchants are made from specific polyether nonionic polymers (PAGs) plus complex additives to obtain other ancillary properties and the right amount of water. In use, quenching fluid may occur in two main categories: one is the change in its cooling performance, and the other is its rust and anti-spoilage performance changes. Because the purpose of using PAG quenching agent is to regulate the water ...
