Abstract
The invention relates to an alkaline soaking and cleaning agent for electroplated parts and a using method of the alkaline soaking and cleaning agent, and relates to an oil and rust removing agent used in a cleaning process before metal piece electroplating, and a using method of the oil and rust removing agent. The alkaline soaking and cleaning agent is characterized by comprising the following components according to mass percent: 40 percent of sodium carbonate, 20 percent of sodium metasilicate, 20 percent of sodium gluconate, 10 percent of trisodium phosphate and 10 percent of a nonionic surface active agent NP-6. During the use, the electroplated parts are soaked into a cleaning agent solution for cleaning before electroplating, rust on surfaces of the parts is dissolved and removed under the effect of an etching agent in the cleaning agent solution, and oil fouling on the surfaces of the parts can be removed under the effect of emulsification. The alkaline soaking and cleaning agent provided by the invention has excellent oil and rust removing effect as well as lubricating and protecting functions, and has the advantages of low operation concentration and low temperature.
