I am an apprentice who just started to learn electroplating. I thought about the function and difference between antipyretic washing and cold water washing. Urgent! ! !

A: Hot water washing just wants to be cleaner, because some components in the electroplating solution will crystallize or precipitate when they meet cold water, but this will not happen with hot water at a certain temperature. For example, some pretreatment liquids have the function of cleaning the grease on the surface of the workpiece, but these pretreatment liquids generally have a sticky substance similar to a cleaner. When the workpiece is taken to the bath, if the water temperature is low, it will not be easy to wash out, which will adversely affect the subsequent electroplating. Therefore,
