Abstract

The invention discloses a dehydrating agent used after plating. The dehydrating agent is based on organic acid and organic amine reactions, and then is formed by adding a complexing agent, a surfactant and polyalcohol. According to the dehydrating agent, an electroplated workpiece to be processed is soaked into a dehydrating agent working solution prepared by adopting the dehydrating agent, and then the workpiece is taken out after a period of specified processing time, and therefore, the effect of rapidly stripping a water film on the workpiece can be achieved, and the workpiece can be completely separated from water; the water stain of the workpiece subjected to dewatering treatment by using the dehydrating agent is greatly reduced after the workpiece is dried, the working efficiency ofthe whole technological process can be effectively improved, and the quality of the workpiece can be improved; and furthermore, the dehydrating agent does not contain heavy metal, no toxic organic solvent is contained, and the agent does not have the gas which is volatile and has the pungent smell, and therefore, the working environment of the operating staff can be effectively improved, the directive requirements of the European Union WEEE & RoHS are met, stainless steel, PVC and other materials can be used as a container, and the selection range is wide.

Description

technical field [0001] The invention relates to a dehydrating agent after electroplating. Background technique [0002] With the continuous development and updating of industrial technology and the continuous improvement of people's living standards, the demand for electroplating products in various industries has increased rapidly. At the same time, electroplating products have also penetrated into our daily life. However, due to the various electroplating processes and complicated operations, a large amount of waste substrates will be generated in actual industrial production. The base material needs to be cleaned with clean water after electroplating, which often causes water droplets to hang on the surface of the base material, so that the base material is prone to watermarks during the drying process. Once the watermark is formed, it will be difficult to remove, which will seriously affect the appearance of the product. To remove the watermark from the substrate requir...
